How to Sharpen a Makita Electric Saw Chain with Your Own Hands

Do-it-yourself chain sharpening of a chainsaw (electric saw)

Having bought a chainsaw once, you don’t need to think that it always works as well as on your first day. The initial apparent ease of processing wood may disappear over time. An inexperienced saw owner may not immediately realize or not see that the saw has become dull.

Ultimately, this no longer leads to sharpening the chainsaw chain for preventive purposes, but to restoring it in special service centers, using machines for sharpening the chain, or even worse, to replacing it with a new one. In this same article, we wanted to talk specifically about timely maintenance and chain sharpening .

When, how and with what help it is necessary to carry out such procedures so that you can saw without problems, and your saw can work efficiently and for a long time.

How to extend the period from sharpening to sharpening a chainsaw

Maybe now we will utter common truths, but some people neglect them, apparently in the hope that everything will work out without it, according to the phrase of the hero of the famous cartoon “Vovka in the Thirtieth Kingdom.” “Oh, that’ll do.”

Under no circumstances should you cut with a saw if there are foreign objects in the wood or board, first of all, nails that have not been removed, or a metal strip. Once you “drive” over a normal nail, you will, of course, even saw it through, but after that, take a look at the cutting edges of the chainsaw chain, because sometimes this is an irreparable defect, with chips and plastic deformation of the teeth.

In such cases, a hand chain sharpening tool may not always help. Before starting work, check the saw area for the absence of any foreign objects; the wood must be clean, preferably dry, although this will depend on how it turns out. You should not cut on the ground without placing something under the cut.

In this case, after cutting you will have to go deeper into the ground, and this is oh, how undesirable for your chain. Earth, sand, stones, all this can also quickly and irrevocably damage the chain of your chainsaw, forcing you to start sharpening it after one or two uses of the new chain.

Make sure that the saw does not “bite” while cutting, so as not to overheat the metal and the blade of the saw. Monitor the chain lubrication and the oil level in the tank. As a result, as you understand, the chainsaw, which seems to be such an “invincible” hand tool, itself needs protection if you want accurate, timely and efficient work from it.

Signs that a chainsaw (power saw) chain needs to be sharpened

Having briefly outlined our thoughts in the previous paragraph about what not to do so as not to start sharpening immediately after 5 minutes of working with the saw, in this paragraph we will talk about the signs of a dull chain, that is, when the time for sharpening has already come, it doesn’t matter how long have you worked? Pay attention to the saw shavings. So, with a blunt chain, it will be smaller, in some cases not light, but slightly darker than usual.

Everything is explained very simply, dull edges cannot remove the proper cutting layer, which leads to shredding, and high speeds without proper heat removal, along with the chips, overheat the wood, causing it to burn and darken.

And of course, the main signs indicating the need for sharpening is a direct visual inspection of the chain.

There should be no radii on the cutting edges, there should be no damage in the form of tears or changes in the shape of the tooth and cutting edge of the chain.

Otherwise, the chain must be sharpened.

Sharpening chainsaws and electric saws. How to easily sharpen a chain

As it turns out, sharpening a saw chain is quite a simple and quick task. All you need is a thin round file.

Negative consequences in case of untimely sharpening of a chainsaw chain

If you continue to saw, despite the fact that the chain is dull, then this will primarily affect your productivity and possibly your nervous system, which does not accept such ordeal. This will also affect the service life of the electric or chainsaw, due to the fact that the engine will overheat.

Increased consumption of gasoline and electricity. It will also be reflected in the shank, which the saw will go through much more times in order to cut the same thickness, compared to a sharpened chain.

The chain may get into such a state that it will have to be adjusted by a machine in a specialized center, or worse, replaced, we have already talked about all this

The process of sharpening a chainsaw chain with your own hands

Sharpening a chain means having a special tool, even for manual sharpening. In fact, this is a set that can be purchased in stores. It consists of a set of two files (round, flat), a mandrel and a gauge. Sometimes it is supplemented with a hook for removing chips from the slots of the chain. One of the files, round, is combined with the mandrel. The flat file and gauge are used on their own, separately.

The chain is sharpened directly on the saw blade. The mandrel is placed on the edge of the cutting tooth, taking into account the chamfer sharpening angle. The sharpening angle is usually 30 degrees or 10.

The most difficult thing about manual editing and sharpening is maintaining this very angle. Here you need to have some practice and feel the direction of sharpening in order to precisely correct the direction of movement of the round file, and not sharpen your own angle.

Also, when sharpening, you should pay attention that the movement of the file should be in a perpendicular plane relative to the saw blade. The main difficulty of manual sharpening is that all angles must be maintained manually, which will require proper dexterity and experience from you.

The file itself should protrude slightly above the tooth when sharpening it.
Sharpening is carried out in one direction, that is, only in a translational motion, and not in a reciprocating motion. Next, after sharpening the first tooth, we turn the chain on the shank and similarly proceed to sharpening the second, then the next one, etc.

After you have “walked” along all the cutting edges of the teeth, it’s the turn of the cut stops. In fact, these are protrusions on chains that do not have cutting edges. The limiters are located on the same plate with the tooth. Their main task is to limit the cutting depth.

If they protrude too much, the chain will slide rather than cut. If they are too deep, the saw will “bite” in the wood.

To adjust the cut stops, you need to take a gauge and apply it also to the edges of the cutting teeth. The end plate with the slot should be exactly at the level of the limiter. If the limiter protrudes from the caliber, then it should be trimmed to size. The stops are leveled with a regular flat file, and also work with the file in a plane perpendicular to the saw blade and in one direction.

Sharpening a chainsaw chain in specialized centers, on a machine (features and cost)

If your chain is in a very poor condition or you feel that you are not able to sharpen it yourself, then contact a specialized center, or purchase a chain sharpening machine that minimizes the influence of the human factor when sharpening the chain.

In this case, the chain is removed from the bar and installed on the machine guide. Next, it is tensioned by a roller and a ratchet holding it by the cutting tooth. The sharpening angle is set according to the protractor on the machine. Next, the abrasive wheel is lowered and literally a few tenths of a mm are removed, that is, the chain is straightened and sharpened.

Next, the chain is moved to the next tooth, etc.

Such sharpening makes it possible to meet higher requirements for the size of the cutting part of the chain and its shape. The disadvantage is also obvious that here you will have to buy an expensive machine, which is not always advisable for one-time sharpening of a chainsaw chain.

The cost of such a procedure in service centers will be about 3-5 dollars, but the machine itself can cost several thousand rubles.

An alternative option for a private owner would be to use a manual machine; it is somewhat cheaper than an electric one, but the processing speed will be somewhat lower, although the accuracy is comparable to the machines used in the service.

Now knowing about all the alternatives when sharpening a chain, you yourself can choose what seems to be the most suitable option.

How to sharpen a power saw chain video

Sharpening an electric saw chain is carried out almost as independently as sharpening any cutting tool. Due to the fact that the teeth of the electric saw have a complex design geometry, it is necessary to select a suitable set of sharpeners. The main difficulty of sharpening is due to the fact that the cutting side and top edges are located asymmetrically, the top one has a bevel at a certain angle to the line along which the chain moves. This is exactly what can cause some difficulties.

Due to the complex structure of the teeth of the electric saw chain, it is necessary to select the necessary tool to sharpen it.

The thickness of the chips will depend on how much the limiter is installed. If electric saws are used very often, it becomes necessary to sharpen the chain. There are times when sharpening needs to be done several times a day. Rapid dulling of the saw occurs during contact with the ground. If the saw touches the ground several times, the process of cutting wood will deteriorate significantly.

Read about aluminum welding technology here.

Practical recommendations

The sharpness of the teeth must be checked regularly. If the teeth become dull and the work continues, a large surface of the cutting elements deteriorates, subsequently sharpening will take more time, and the damaged surface will have to be removed. If you sharpen a chain on time, you can extend its service life.

The position of the file when sharpening the chain of an electric saw.

In order to determine the quality of the teeth, it is enough to pay attention to the chips. If it only comes out small, then the chain needs to be sharpened. This factor can also be determined when inserting the saw into the cut; if it enters with little effort, everything is fine, work can continue. If this requires great effort, the saw chain has become dull. You can also visually assess the condition of the instrument by inspecting all the elements.

A dull saw not only performs cuts poorly, it negatively affects the entire tool. Since the cut is carried out with great force, the tension spreads throughout the entire tool. The load on all components in the saw increases, productivity decreases, more energy is consumed, and productivity decreases. Such phenomena can damage the instrument and cause it to malfunction in the shortest possible time.

Basic parameters and elements of electric saw chain teeth

Cutting link design:

• base;
• tooth blade;
• depth limiter.

In order to get maximum results when cutting, all saw teeth must be sharpened at a certain angle. The rear corner is formed by the back, which falls at an angle back. This part is responsible for properly cutting the blade into the wood. The blade forms the back corner of the blade. This part of the part is designed for side cutting of wood chips.

Diagram of the electric saw tooth structure.

The end edge of the blade and the sliding surface of the cutting link itself will together form the rake angle.
Electric saw chains can have this angle in different sizes. But on average the range is 60-85°. The most important angle is the rear angle, which is responsible for the upper blade. There is no exact degree scale for this angle, but in order for it to be sharpened correctly, the rules described above must be followed.

The sharpening angle of the electric saw can be changed depending on the specific case. It is important to adhere to the rule: the higher the sharpening angle, the greater the cutting performance will be, especially when cutting soft wood. But despite this, it is necessary that the sharpening angle be within 35-25 °. There is only one exception - this is a rip saw, in which this angle will be equal to 10 °.

The depth limiter controls the depth to which the upper blade can go. On average, this figure is in the range of 0.5-0.8 mm. If the limiter is installed to a greater depth, vibration may occur, and the saw may also produce kickback. Settings that are too low will result in poor performance.

Basic rules: how to sharpen a chain

It is worth immediately noting that the contour of the inner surface of the tooth is very close in shape to a circle, so it is worth using a file with a small diameter to sharpen the chain. In addition, the metal from which the teeth are made is quite soft and sharpening the chain will not be difficult.

The location of the front sharpening angle of the cutting chain link.

It is very important to choose a file in accordance with the size of the chain, because sharpening requires strict concentration and a steady hand. The tool should protrude 20% relative to the top edge of the tooth when sharpening. If sharpening is carried out in a horizontal plane, the file must be held at a right angle. If sharpening is carried out vertically, the file should be held at an angle of 30 or 10 °.

To do a good job of sharpening teeth, it is necessary to use several tools, since it is quite difficult to complete all the work with just a file. To carry out such manipulations, you need to use a set of tools that comes with the electric saw. If there is no such set, it is worth purchasing it separately in the store; the tools can also be purchased separately, the main thing is that they fit the dimensions of the chain and teeth.

Basic tools used to sharpen a saw

The kit for carrying out such work must include:

• two files: round and flat;
• a special hook that is used to clean sawdust from sawdust.

Sharpen teeth or buy a new chain for your electric saw? | Electrician in the apartment, repair of household electrical appliances

How long does a regular hacksaw or two-handed “friendship” saw last without setting the teeth? For some, for years, for others, six months after purchase - “at least throw it away.” About the same thing happens with a chain for an electric saw.

If with a hand tool everything is clear, since even with a completely chipped tooth the saw can be reanimated, then with an electric saw this problem does not work: the speed of work and the force applied to the cutting site are much higher.

Because of one eaten tooth in one or two approaches to the tool, the entire chain fails.

The saw chain is the most loaded element of the electric saw, so the design provides for the possibility of replacing it. The ideal option is to purchase a product from the same manufacturer and the same dimensions, including the pitch of the teeth and their sharpening angle, that is, a complete analogue of the “native” one, but sometimes this problem cannot be solved: you need to work now, but the search may drag on for a month. You have to make a choice from what is available in the nearest market, or place an order via the Internet.

How to choose a saw chain for an electric saw

For an existing electric saw, a replacement chain is selected based on three main characteristics: pitch, thickness and length. Unfortunately, there are no tables of interchangeability of chains from different manufacturers; it remains to be understanding about each parameter.

The traditional definition of chain pitch is in inches, but since there are only three standard sizes for a power saw, they are not so difficult to remember: 1/4″, 0.325″ and 0.375″ (3/8″). More serious sizes 0.404″ and 3/4″ are designed for professional chainsaws; the power of the electric unit (plus or minus 2 kW) will not be enough to get a normal cut.

Thickness matters because the saw element is guided by a bar in which a groove is provided. Here the dimensions are simpler: 1.1 mm, 1.3 mm and 1.5 mm are variations in the width of the groove.

The length of the chain itself is rarely indicated in the accompanying documentation. The bar size is often indicated in centimeters or inches; for an electric saw, the maximum bar length is 45 cm (18″).

Use on your websites and blogs or as a clicker for adsense

But a chain selected solely by the length of the bar (with other suitable parameters) not from the manufacturer of the saw itself may not be suitable due to the fact that the number of drive links will not correspond to the size of the sprocket that sets the movement.

If the documentation for an electric saw indicates the number of links, this parameter should not be neglected; it is more important than the pitch of the teeth, which affects the quality of the cut (even or “it will do”) and performance, which is not important for an amateur. If the documents are lost, no one can stop you from counting the number of drive links manually and remembering them.

Is it worth sharpening your saw chain yourself?

When an electric saw is used occasionally, for your own needs, for example, to trim trees, prepare firewood for a bathhouse, repair a fence, gazebo or bench, it is irrational to fool around with its repair. Moreover, most often budget versions of electric saws are in use, and replacing a chain when the cutting edges of the teeth have worn out or “caught a nail” is a common and not very expensive thing. In financial terms, this will cost from 400 to 700 rubles.

But a real owner, who is used to doing everything himself and treating the existing tool with care, can very well extend the life of the chain by starting to restore it.

In the long term, this is economically beneficial, but in the short term it makes almost no sense, since decent quality cannot be achieved with one or more files without a special device, and it will take a lot of time.

A set of tools for almost professional sharpening of teeth (flat and round files, caliber, mandrel), which can be ordered or purchased either selectively or as a set, will cost about 1,000 rubles (vises are not included).

The cost of a manual device for sharpening saw chains for an electric saw or chainsaw starts from 1.5 thousand rubles, a machine with an electric drive – from 2.5 thousand rubles. The owner of the equipment will quickly justify the costs if he starts sharpening for friends and neighbors (not for free). In service centers, sharpening is expensive, about 100 rubles. for a bit, but with budget products, as a rule, they don’t go there.

When is it time to sharpen, and when is it better to change?

The easiest way to determine that the teeth are dull is by their appearance, and a change in the nature of the sawdust can be a reason to pay attention to them. Small pieces of wood, quite light in color, fall out from under the new electric saw. Over time, their size decreases to a dusty state and their color becomes darker. If these signs are completely ignored, even the smell of burnt wood may appear.

If you don’t want to buy a new saw, you need to monitor the condition of the saw chain.

Even if the owner himself cares for all components of the electric saw, it is a good idea to have a spare chain. For example, there is no time for sharpening, and work does not wait. The ideal solution is to immediately, along with purchasing the tool, buy a spare part similar to the installed one, but how many of us think about this? However, it is never too late to correct a mistake: you need to be prepared for the fact that after 6-8 sharpenings the teeth will not be restored. Just like urgently purchasing a replacement.

Electric saw chain - lubrication, sharpening, how to put it on correctly

The bar and chain are elements of an electric saw, the main function of which is to cut wood. Its effectiveness on the site largely depends on the condition and serviceability of the saw set of a garden tool: the ability to fell dry trees or carefully saw logs. To maintain high performance of the electric saw, its operator must monitor the condition of the bar and chain, regularly add new oil to lubricate them, and also change the saw parts as they wear out.

How to sharpen a power saw chain with your own hands?

To sharpen the saw blade of an electric garden saw evenly, its owner has 3 options. The first method is manual.

It consists of using two files - round and flat, as well as a holder necessary for attaching a round tool.

The round file must be selected taking into account the chain pitch - the larger it is, the larger the diameter of the file used. A flat file is needed to process the stopper, so it can be of any size.

The procedure for sharpening a chain with files is as follows:

1. First, the holder with a round file pre-fixed in it must be installed on the cutting chain of the electric saw. There are arrows on the bar that should be parallel to the guide rail;
2. Next you need to check the sharpening angle. After making sure that the upper blade of the cutting tooth of the chain is located at an angle of 25–30⁰, you can begin sharpening;
3. The operator's movements must be uniform and directed only forward. Each of the cutting teeth of the chain must be processed the same number of times.

The second way to sharpen the cutting parts of an electric saw is to use a set of files and a special template. The template already contains the necessary parameters: angles of inclination and processing of the teeth. In addition, sharpening the electric saw chain using a template allows you to evenly process the stop tooth.

During the restoration of the cutting teeth, the template is applied to each of them in turn. It is equipped with moving rollers along which the file slides while working with the chain. At the same time, the sharpening angle is not disturbed, which makes the restoration of each tooth uniform.

The only disadvantage of this method is the need to use a separate template for each specific type of cutting element, taking into account the pitch of the chain, the width of its shank, the drive link and other parameters.

The third sharpening method is to use an electric machine. This option is considered the simplest, fastest and most convenient. Most machines come complete with metric and graduated scales, which allow you to restore almost any chain, regardless of its pitch and number of links.

The use of an electric machine is suitable for people involved in regular felling and sawing of logs. In other cases, it is not practical to buy specialized equipment.

How to properly put a chain on a power saw?

To install a new cutting set, the user of a garden electric saw will need a screwdriver, gloves made of thick fabric, and a wrench.

To install the chain on the electric saw, you need to follow the following procedure:

1. First, you need to unscrew the guide bar mounting nuts using a wrench. Before doing this, it is important to make sure that the inertia brake is in the off position. Otherwise, the operator risks breaking the tension cable of the inertial mechanism;
2. Then you need to carefully move the brake pad to the side;
3. Next, you need to move the guide bar, while trying to engage the drive sprocket of the electric saw. This is necessary in order to remove the part of the tire mounted on the sprocket. The rest of the guide - its shank, is attached in special holes;
4. After this, you need to put the chain on the electric saw and adjust the tension of the cutting element, using a separate plastic tensioner for this;
5. Then you will need to install the protective cover and unscrew the bolts securing it completely.

How to sharpen a chainsaw chain with your own hands?

The chainsaw chain requires regular maintenance and sharpening. This affects the performance of the tool, wear rate and operator safety. You can determine the need to update the cutting edge of the teeth by the presence of sawdust on their surface and the characteristic dull sound during sawing. To sharpen the tire, you can use an electric or manual machine, an angle grinder, or a regular file. Each method has its own advantages and disadvantages, specific skills.

Circuit structure and parameters

Before starting work, you should determine the basic characteristics of the chain set. The choice of sharpening method, tool and the need for the procedure depends on this. What to look for:

• Features of the link . It consists of a base, a tooth blade, a depth stop, and two blades. You should carefully inspect each element, identify obvious defects and mechanical damage - they need to be dealt with first;
• Blade angle . It is this that allows the chain to cut wood and determines the volume and shape of wood chips. There should be no defects on it. The parameter of the upper blade varies from 50 to 60o, the end blade – from 60 to 85o;
• The tire profile height can be 0.625 mm or 0.762 mm . When processing limiters, you should fall within this range to reduce vibration of the tool during sawing.

Figure 1 – Types of saw chains

The second most important characteristics are the type of metal and chain pitch. For soft and medium-density materials, a regular file is suitable; it will do an excellent job of sharpening. For hard metal chains with frequent link pitches (from 0.36 inches), it is recommended to use only the machine straightening method.

Important ! The main parameters of the headset and its elements can be found in the operating instructions. Detailed technical specifications are always presented on the manufacturer’s website.

When is sharpening necessary?

You can determine the need to sharpen the chain teeth while working with wood. The speed of operation decreases, the instrument produces characteristic sounds. Typical signs of a dull blade:

• the saw does not bite into the wood, but moves from place to place, like a grinder;
• when working with hard rocks, the headset does not penetrate into the thickness of the log, so mechanical force must be applied;
• the chips take on a loose appearance and rarely crumble during operation;
• All parts of the chainsaw heat up above normal, and the smell of burnt oil appears.

A high-quality chain should have teeth with an even metallic sheen. There should be no rust or plaque on any part of the link. It is not recommended to use the tool if there are chips, dents or other mechanical damage to the cutting edge.

Types of sharpening saw chains

There are a number of tire sharpening technologies. In the field or at home, you can use a grinder or a file. This method is suitable for budget chainsaw models when high precision tooth adjustment is not required. The main disadvantage of this method is the need to control the mechanical pressure on the hand tool; with increasing pressure, you can remove an excess layer of metal and deform the teeth.

Professionals recommend using special machines for initial sharpening, and then a vice with guides for grinding and adjusting each link. This method helps save time, and when using holders adapted to a specific chain pitch, the likelihood of error is minimal.

How to sharpen using special equipment?

The most convenient way to sharpen a saw is to use special tools and machines. This allows you to quickly carry out work of any severity. When purchasing a chainsaw, it is recommended to immediately buy a template to determine the values ​​of the end and top blade, and the front edge angle. In addition, you need a file to eliminate minor defects.

Important ! All necessary tools, depending on the chosen method, must be prepared in advance. This will simplify the work and increase sharpening accuracy.

On a manual machine

Figure 2 – Sharpening on a manual machine

In practice, this method is usually used to trim the teeth after each long-term use of a chainsaw when working with hard wood. The “hand saw” looks like a regular beam saw with a small vice for mounting on a headset. Instead of a blade, there is a round file on it.

Before starting work, you should secure the tool to the headset and set the parameters in accordance with the features of the saw. This is done only manually using certain marks on the machine. Stopping at each blade, make 3-4 movements towards yourself to sharpen. This method is not suitable for restoring very dull saws.

On an electric machine

Figure 3 - Electric machine for sharpening saw sets

This is the most convenient way to sharpen a chainsaw bar of any brand. No special skills or abilities are required; the work process itself takes no more than 10 minutes. The machine is equipped with an electric drive and operates from a DC source with a voltage of 220-240 V. When choosing a device, pay attention to the following features:

• the presence of a function for sharpening teeth with different intervals of links, the volume of the upper edge;
• possibility of sharpening angle correction;
• replaceable grinding wheels included;
• stable cutting width.

The saw chain is fixed into a guide as part of the base platform; it also has a special mechanism for holding the teeth. It can move in a horizontal direction.

The grinding wheel is lowered at an adjustable angle to the cutting edge; the degree of pressure can be controlled with a regulator. The sharpening element is directly immersed by the operator.

For convenience and accuracy of work, all models have a measuring scale with which you can evaluate the degree of sharpening of all components of the chain teeth.

Bulgarian

This method is used only in the absence of other necessary devices for chain correction. It is optimal for rough straightening of teeth, but has a serious drawback - it is difficult to control the angle, and there is also a risk of damage to the connecting rivets.

To sharpen the chain, the angle grinder must be securely fixed in a vice. Turn on the tool, and then bring each cutting edge one by one and hold until shine appears. You can check the required angle using a caliper.

Important ! When using a grinder, the chain should be constantly lubricated with oil. This will help to avoid too much grinding of the cutting edge, burrs and other mechanical defects in the metal.

Angle of sharpening on the machine

A quality tool always has markings with which you can evaluate the quality of sharpening. When working, you need to focus on its indicators in order to maintain the performance of the headset. The table shows the main characteristics of the teeth depending on the chain pitch and the characteristics of the links.

Figure 4 – Recommendations for sharpening depending on the parameters of the chain

How to sharpen by hand using a file?

Using a file is the easiest and most cost-effective way to correct the sharpness of a cutting edge. The procedure will also require a vice to securely secure the tire in a stationary state. The choice of file type and diameter depends on the characteristics of the chain and the technology of the procedure itself.

Determining the file diameter

It is easier to sharpen a chain with a round file with a holder, the diameter of which is selected depending on the pitch of the links. The table provides information for proper selection of tools.

Step	File diameter
0,25	2×2
0,325	2×2,4
0,375	2×2,6
0,404	2×2,75

File parameters

Despite the simplicity of the operation, using a file can ruin the quality of the tire. Useful tips for sharpening:

• primary sharpening is carried out with a round file of different diameters, and to correct the sharpness of the metal, a flat tool is used;
• it should not extend beyond the top of the cutting blade by more than 20%; the same clamping force should be maintained;
• movements are performed from oneself, the number of repetitions should be equal for all teeth;
• to correct the vertical plane, place the file strictly at a right angle;
• horizontal elements are sharpened at an angle of 20-30o. Figure 5 – Set of files

It is necessary to take a fresh file with pronounced abrasion. A worn instrument will increase the duration of the procedure and reduce its effectiveness.

How to carry out the process yourself at home - step-by-step instructions

You can straighten a chainsaw chain using a file even at home. It is important to choose the right tool and follow the technology. Step-by-step algorithm:

1. Secure the tire with a vice so that its upper part is in a horizontal plane.
2. Mark the shortest tooth with a marker or nitro enamel - it will serve as a reference point.
3. Place the surface of the round file behind the main cutting edge and press it along the entire line. Due to the holder, it will automatically take the required position.
4. Without changing the angle, run the tool along the beveled surface 3-4 times. If necessary, rotate the file around its axis to achieve the required sharpness.
5. Check the height of the stopper with a special template, adjust the sharpening with a flat file. Figure 6 - Sharpening a chain with your own hands using a file

Repeat the manipulation with each link up to the marked reference point. Turn the chain over and sharpen all other teeth in the same way.

Important ! When sharpening a chainsaw with a file, you should blow off metal shavings as they appear. This will allow you to evaluate the sharpness of the metal.

Features of longitudinal and cross cutting

The sharpening angle requirements also depend on the characteristics of the chainsaw; depending on the purpose, the tire can be used for transverse and longitudinal sawing. In the second option, the edge should be very sharp, its angle should be in the range from 6 to 12°, for a transverse one - 25-30°. For longitudinal cuts, the chain should be sharpened as often and efficiently as possible; wear of the teeth can lead to uneven cuts, reduced productivity and clamping of the headset into the wood.

Stihl has developed special recommendations for sharpening the tire with a file or grinding wheel. The general operating algorithm remains the same. The table shows the requirements for choosing a blade diameter depending on the chain pitch.

Figure 7 – Dependence of file sizes on Shtil chain pitch

Expert recommendations

There are useful tips for sharpening your chainsaw quickly and efficiently. General recommendations:

• first you need to run in the headset at low speeds, this allows the lubricant to get to each element of the tire;
• the circuit must be energized; loosening may result in injury, especially when using an electric machine;
• It is recommended to edit the headset after each prolonged use of the tool, carefully check the teeth before starting sawing;
• lubricate each element of the tire in a timely manner, which not only improves the process of working with wood, but also reduces the load on the rotor and engine.

The depth of cut, the condition of the cutting edge and the stop must be checked after 3-4 sharpenings. It is recommended to check the template for your specific headset model.

Sharpening a chainsaw chain is an integral part of working with this tool. The sharpness of the teeth affects performance and safety during sawing. To straighten the cutting edge of the tire, you can use an electric or manual machine; at home it is easier to use a file. You should take into account the features of a specific headset model and measure each element with a template.

How to sharpen a chainsaw chain: an overview of methods

Sooner or later, the chainsaw chain will need sharpening. Of course, you can take the saw to a service center, where everything will be done quickly and without problems, but many owners are interested in always being able to sharpen the saw with their own hands. And since this can be done in several different ways, it is worth considering them all, as well as the pros and cons, the convenience of one method or another.

What are the dangers of working with a blunt instrument?

Do not use a dull chainsaw chain

Working with a faulty tool in itself is fraught with many unpleasant consequences, and here are some of them:

1. Reduced efficiency, that is, less work will be completed in the same time.
2. The mechanism begins to wear out, and individual parts are also at risk of breaking.
3. Excessive fuel consumption.

How can you tell if a chain is dull?

There are several signs by which you can understand that the chain is currently not suitable for operation:

1. You need to put in more physical effort for the same action.
2. Chain stretching.
3. Feeling of vibration when working with a tool.
4. The unevenness of sawdust, which, moreover, becomes more like dust.

According to many experts, a well-sharpened chain is more important than engine power.

The chain can also become dull for several reasons:

1. Mishandling.
2. Contact with objects that are too hard, such as stones.
3. Too voluminous and long-term work.

Methods for sharpening a chainsaw chain

As mentioned above, there are several different ways to do this. The most popular are:

• sharpening with a file,
• grinder,
• electric machine
• and the so-called “manual” machine.

File

The file will do a good job of sharpening the chain

This type of sharpening is the simplest. This set includes a round and flat file, special holders, a gauge template, a hook for removing chips and others. And although the filing tools may differ slightly, they nevertheless have approximately the same logic and the same functionality.

The diameter of the round file directly depends on the size of the chain:

• Chains with a diameter of 1.3 require a file of ø 4 mm (used much more often).

Proper sharpening of a power saw chain - Ice advice

Do-it-yourself chain sharpening of a chainsaw (electric saw)

Having bought a chainsaw once, you don’t need to think that it always works as well as on your first day. The initial apparent ease of processing wood may disappear over time. An inexperienced saw owner may not immediately realize or not see that the saw has become dull.

Ultimately, this no longer leads to sharpening the chainsaw chain for preventive purposes, but to restoring it in special service centers, using machines for sharpening the chain, or even worse, to replacing it with a new one. In this same article, we wanted to talk specifically about timely maintenance and chain sharpening .

When, how and with what help it is necessary to carry out such procedures so that you can saw without problems, and your saw can work efficiently and for a long time.

How to sharpen a chain saw

» Articles » Repair » Repair

Good afternoon friends. We will devote this video to saw chains of petrol and electric saws. 4 or 5 times we sharpened the chain at the Petrovichs and Mikhalychs, i.e. from the local Kulibins. After which they successfully turned our beauty into such a stub. It became a little offensive, and they began to figure it out themselves. We watched a bunch of videos, read articles and realized that the truth had to be literally picked out from this pile. First, about the circuit design. Like a regular one, it consists of links. One link, two links, three links. Each has two rivets. The most convenient way is to count the rivets and divide them in half. We had 104 rivets, which means 52 links. The saw has 2 sprockets - one driving and one driven at the end of the bar. For the chain to move normally, it must match their pitch. Chain pitch is the distance between any first and any third rivet, divided in half. For more accurate measurements, you can expand the range. We have approximately 9.5 mm, which means the standard is 3\8″. The chain slides along the bar. There is a groove in the tire for this. And the chain has an element - a shank, which fits into this groove. Of course, they must match in size. But but but. Our tire did not have a groove size. We tried it on. About 1.5 mm. This means the shank should have either 1.3 or 1.5. And the length of the chain must also match the tire. The tricky thing here is that for some reason the tire size is approximately this distance. We measured it - 35 cm, or 14″. To our great joy, we found confirmation on the casing. That's it, you can buy a new chain. We bought Husvarna rubles for 600. Tire 14″ pitch 3\8″ shank 1.3 mm 52 links. Everything is like in a pharmacy. I couldn’t bear to wait for filming, so we immediately tested the new chain in action. No questions. Now, let's remove the dirty one. The saw chain has cutting teeth. Some are left-leaning, others are right-leaning. They go through one. This and much more of the chain is done to reduce vibration. Here is an element called a cutting depth limiter. The lower it is below the cutter, the deeper it cuts. (For amateur saws, this gap is somewhere from half to one mm. For professionals, it can be larger.) The tooth has two cutting edges - a working horizontal one and a lateral vertical one. One of the main parameters is the working angle, or angle of attack. (The teeth for sawing across the grain and along are very different. For a saw across the grain, the angle is from 25 to 35 degrees. For longitudinal - from 5 to 15 degrees.) Here are the basic standards for chain pitch and shank thickness. The question is why in the step size they use either decimal values ​​or fractions. We answer - exclusively, so that it would be easier to distinguish them and not be confused. It's time to sharpen. This is where the Kulibins make a rustling sound and use whatever they can to sharpen them. Let's figure it out. The cutting tooth is made of special steel that has undergone heat treatment. This means that it cannot be overheated. It turns out that when sharpening with an emery wheel, as in conventional metalworking, the processing area needs to be cooled, for example with water. Nobody does this. Go ahead. In the same Husvarna, Shtil, etc. Scientists and engineers are sitting there, they think, testing these chains of theirs for years. Find the ideal sharpening geometry for each chain. Then we come and do our geometry. We don't give a damn about these capitalists. We show you - here is the factory sharpening. We had a sharpening machine. To give a greater degree of freedom, we removed the head part. And even with all the freedoms, it is completely unrealistic to get here with an emery wheel while maintaining the geometry of the tooth. And if the machine is assembled, there is nothing to do there at all. Of course, among a thousand sharpeners there will be one left-handed, self-taught person who won’t overheat a tooth with a grinder and will maintain the geometry. But he has to perform for money in the circus or at the Olympics, and we are simple people, many have not held a grinder in their hands. Please note that all branded rollers are sharpened exclusively with files using guides. Scientists are respected. We take an even closer look at the packaging of the chain. There is no hint of either the sharpening angle or the diameter of the file. And the Internet does not respond to all local numbers. Clearly, the machinations of the CIA. We take the reference table from the smart article. For the shank we need a file of 4 mm, for a pitch of 5.2 mm, according to the seller of files 4.8 mm and let's get ahead a little - according to our subsequent measurements it would be better to take 3.2. We trusted the seller and took a package of 4.8 for 70 rubles each. We secured the saw; it would have been better to put the tire in a vice, but it wasn’t at hand. We begin to insert the file. Well, you get the idea. The country of the Soviets lives and wins. In the same clever article we find this drawing. You see the ratio. This is more like the truth. Let's get ahead of ourselves again - they called Shtil later. Their smallest diameter is 4 mm. We've arrived. But, nevertheless, the idea is clear - using rods, pencils, nails, you select the ideal diameter for yourself and then buy the right files. There's nothing to do, let's show this. According to the instructions, or by eye, determine the angle of the factory sharpening. We are working. You see how the file moves, and with it the sharpening angle. This is not sharpening - this is squalor. Capitalists use guides. Here are their examples. In my deep conviction, such devices will not save, at least a young fighter, from file wobbling. And it’s a pity to occupy two hands. Yes, and you need to buy it first. But this option is already closer to the truth, only we will offer it 100 times simpler and several times more accurate. We go to the barn, find a thin rod, connect it to the file with simple electrical tape. We take a beam and attach a piece of iron to it. We make a mark on the tire. Every right Tooth should be here. We set the correct sharpening angle and drill a hole in the right place. The right teeth have run out, we set the angle again, changing the position of the beam or tooth. We sharpen the left ones. That's it. This device is more accurate than all the previous ones combined. Because the further the support, the smaller the angle of deflection. Geometry. Every man with his hands, even on the basis of his own barn, can improve this design ad infinitum. But his hands are not official ones either. We mechanize. One of the ideas we looked at was, of course, a jigsaw. There is no need to change anything in the design. The option with a drill or screwdriver is not so bad. But then you need to connect the file and the rod through a tube. A similar structure can be built in the forest. But there is a significant problem here. If the teeth are too hard and the file is weak, then the tooth will sharpen the file, and not vice versa. Therefore, when buying a combination of chain and file, you need to use your maximum intelligence. Another option we looked at is a diamond-coated file. But additional tests are needed here. And one last thing. When sharpening, the height of the cutting tooth decreases; the depth stop must also be filed down. This is where a simple cutting template will be useful. Of course, there are chains that you can get to with a machine. Their teeth have a special geometry, and they themselves are designed for longitudinal cutting. Discussion So how to properly sharpen a saw chain? There are many opinions and methods. Some of them are true, others simply don't work. So in our case, we bought the right 4.0 file and the sharpening went like a charm. There are wealthy saw owners who buy a couple of spare chains at once and change them, I have also met professionals who sharpen the chain perfectly without any tools. But they don’t need our considerations. We tried to offer a method that is easy and cheap to implement and that will prevent an “amateur” from damaging the chain. What do you think? We are waiting for business comments. We recommend viewing Personally, in this video I liked the explanation about the control notches that are made in order to indicate the limit of tooth grinding. After all, grinding further is simply dangerous!

Sharpening a power saw chain

As with chainsaws, the main working parts of an electric garden tool are the bar and chain.

https://www.youtube.com/watch?v=yrFrBHIwrIw

The performance of an electric chain saw, the volume of fuel it regularly consumes, as well as the quality of the wood cutting line largely depend on their quality and technical parameters.

In order to constantly maintain stable operation of a garden tool, its owner must study the rules for selecting, installing, maintaining and repairing a cutting set. This will allow you to maintain the operation of the tire and chain of the electric saw in order until the end of their service life.

How to choose a chain for an electric saw?

To choose the best cutting attachment for a particular electric saw, the gardener needs to study several important parameters and criteria of the chain:

• length - must correspond to the length of the installed metal guide. Some novice users try to install shortened cutting parts on the tires of their tools, believing that over time they will still stretch and fit tightly onto the tire. This is a big mistake, since the length of the guide and the new headset should be the same. If the chain sag as a result of use, it can be easily shortened by removing several links;
• Factory sharpening angle – parts sharpened at an angle of 30⁰ are easier to bear increased loads. For regular work with frozen and damp wood, headsets with an angle of 10⁰ will be most effective;
• manufacturer - in order for the cutting tool to fit perfectly onto the bar, you need to choose products from the manufacturer of the installed guide and the electric saw itself. For example, for electric saws and tires manufactured by Makita, you need to choose chains from the same manufacturer.

To choose a chain for a power saw, the owner of the equipment must take into account the purposes for which the cutting set will be used. To be able to cut relatively large wood, chains with a pitch of 3/8″ are suitable. If the loads are not high, then for installation on a power tool it is better to choose cutting sets with a pitch of 0.325″.

How to properly put a chain on a power saw?

Most often, to allow the operator to independently install a new cutting element, a side tensioner is provided in the electric saw device. To install a chain on a power saw with such a mechanism, its owner must perform the following steps:

1. While lowering the brake lever, move the plastic operator protection shield with your other hand;
2. Carefully turn the built-in tension screw using a screwdriver;
3. Unscrew the nut to release the tension on the cutting element;
4. Carefully remove the instrument body cover;
5. Remove the metal guide from the sprocket;
6. Remove the worn out old chain;
7. Place the chain on the guide and install the cutting parts back on the saw.

The tension of the electric saw chain should be smooth, without jerking. To do this, you need to slowly tighten the headset, install the protective plastic cover of the saw, and tighten the saw body using a nut and screw.

Installation of the chain on some modifications of electric saws is done using built-in wing nuts, which allow you to quickly install and tighten the headset. Replacing a chain on a power saw with this type of fastening should be like this:

1. The operator will first need to lower the brake lever, unscrew the retaining nut and remove the factory protective cover;
2. Next, you need to move the guide back and carefully remove the old headset;
3. After this, you will need to install a new chain, putting it first on the sprocket, and then along the entire length of the guide;
4. Then all that remains is to install the built-in sprocket in its original place and tighten the nut tightly.

At the end, the operator must turn the tension wheel in the direction indicated by the arrow and tighten the standard “thumb” to the end.

Do-it-yourself electric saw chain sharpening

It is best to entrust the restoration of the cutting set to professionals from the service center. If this is not possible, then you can sharpen the electric saw chain yourself.

To do this, the gardener will need a kit that includes:

• a round file with approximate lines marked on it;
• flat file necessary for adjusting the depth stop;
• calibration device;
• mandrel required to select the correct angle.

When processing teeth with a round file, the operator must constantly ensure that its surface protrudes above the chain teeth by no more than 1/5 of its length. It is best to mark the first tooth to be processed in advance so that you do not have to sharpen it again later. All operator movements must be strictly in one direction.

After processing each tooth, it is necessary to proceed to the restoration of its limiter. To do this, you need to attach a calibration device to its edge. As a result, the end part should be located next to the limiter. Otherwise, the stop will need to be trimmed using a flat file. Thus, the calibrator must be perpendicular to the saw bar.

Sharpening a chainsaw chain with a set of files, a grinder, on an electric machine and using a special system

Electric and chainsaws are included in the arsenal of many private home owners, along with such devices as a drill, hammer drill, etc. This tool has one negative side - the chain gets dull from time to time. You can sharpen it yourself if you know how to do it correctly.

How to determine if a chain is dull

Anyone who has ever used a sharp chainsaw will quickly understand when the chain needs sharpening. There are several ways to determine this:

• instead of shavings, when cutting wood, practically dust falls out;
• the time of operations increases;
• you feel the strain on your hands;
• fuel consumption increases;
• the saw gets stuck and breaks out of your hands;
• The cuts turn out crooked.

Sharpening should be carried out as soon as possible, and not only because it becomes difficult to work with the tool. When using an unsharpened chain, its service life is shortened and the mechanism of the chainsaw itself wears out faster and fails ahead of schedule.



What to sharpen

Sharpening a chainsaw chain is not an easy process. There are three options that are used today:

• using a file;
• Bulgarians;
• special sharpening machine.

Similar methods are used when sharpening knives, scissors and other cutting tools, so nothing extraordinary has been invented here. However, there are also special tools for sharpening the PowerSharp system. They allow you to quickly sharpen saws at home, which have a special mark indicating the design features.



File

Using a set of files is the most common method that can be done at home. But it is not as simple as it might seem at first glance. To carry out sharpening, you will need two types of files: round and flat. Each of them has its own purpose.

Using a round tool, you need to sharpen the working edge of the saw tooth, because its configuration is rounded. For household chainsaws, a file with a diameter of 4-5 mm is used, because the saw teeth are small. Professional saws are sharpened with files with a diameter of 5.2-5.5 mm.

Use a flat file to sharpen the cutting depth limiter. If this edge is not adjusted, the chain will not cut into the wood to the required depth, which will reduce the cutting speed. And this will directly affect both excessive fuel consumption and overheating of the saw engine.



How to sharpen with files correctly

First of all, the power tool must be prepared. It is installed on a flat surface, it can be a table or a workbench. The chain is tensioned to the maximum, set to brake mode, for which the locking lever is turned. The saw teeth are inspected for defects: chips, cracks, complete fractures, etc.

As for the process of sharpening chainsaw chains with your own hands, there are several recommendations:

• The teeth must be sharpened with a file from the inside out;
• there is a mark on the chain that the manufacturer applies specifically to indicate the degree of sharpening;
• The tooth to be sharpened should be located in the middle of the chain for ease of work;
• sharpened, removed the chain from the lock, moved the next tooth to the middle, and put it on the brake.

You need to work with the saw carefully, wearing protective gloves, because the teeth of the chain are quite sharp. The number of movements along the plane of the edge varies depending on the damage to the teeth.

Accessories

Construction stores sell special holders that make it easy to sharpen the chain of an electric or chainsaw, because they clearly indicate the sharpening angle and the depth of the stop. Having installed the device on the chain, you just need to adhere to the configuration of the holder without going beyond the stops. In principle, this will not work, so the teeth sharpened on the holder have the required angle and depth parameters.

Another device that makes sharpening easier is the so-called machine for straightening the teeth of saw chains. The device is secured to the chain bar with special clamps included in the design of the device. The guide is set at an angle that determines the degree of sharpening. It can be adjusted by changing the parameter.

The tooth to be sharpened is secured with a special stop, on which a file is also placed. This type of machine is produced by a large number of different manufacturers. The instruments may differ purely in appearance, but structurally they are all the same.

Please note that first the working edges of the teeth are sharpened by hand, and only after that the depth stop is trimmed. In this case, it is necessary to strictly maintain the difference in the height of the tooth edge and the upper plane of the stop.



PowerSharp system

It should be noted that this device cannot sharpen all types of chains. They are suitable for their own chains and tires marked PowerSharp. The bar is easily inserted into any saw, and it has one difference from the standard ones - an additional hole in the front.

The sharpening system comes with a plastic block into which the sharpening stone is installed. That is, a bar is inserted inside the block, on which a chain is previously put on. It is fixed there with a pin, which is inserted just through an additional hole in the tire. The block is closed with a lid. At the front of the block there is a key that functions as a lever. It must be bent, thereby pressing the abrasive stone to the teeth of the chain.



After this, the saw must be rested on the ground with the key and turned on at maximum speed. A couple of seconds, and the saw is sharpened.

Sharpening machines

Nobody in service centers uses files for a long time. Because correct sharpening of a chain means precisely maintaining the parameters of the angle of the teeth and the height of the stop.

It is difficult to achieve this manually, but the service center guarantees the quality of the operation with long-term operation of the electric or chainsaw.

The variety of sharpening machines is amazing. There are both ordinary simple mechanical devices and electrical ones. At the same time, manufacturers offer small-sized machines that are installed directly on the bar, desktop ones, in which the chain is installed without a bar.

The simplicity of the sharpening procedure is due to the fact that the sharpening machine has a retainer in its design in which the chain is secured. It is installed so that the chain is fixed vertically in it.

You can adjust the installation location of the device. This is quite simple to do, because the latch can move in a horizontal plane. The angle of inclination is determined by the abrasive disk (circle), which is mounted on the motor shaft. This way the sharpener is positioned at the required angle set at the factory. But it can also be changed depending on the required degree of inclination.



For example, for cutting hard wood an angle of 20-25° is required, for soft wood - 30-35°; to cut wood along the grain, you can use chains with a tooth angle of 10°.

The rotation of the disk is carried out by an electric motor, but its immersion is carried out manually by the operator. But even here you can set the necessary parameter so as not to increase the depth of the cut. By the way, the disk is a removable element.

Sharpening with a grinder

As it turns out, the grinder is a universal tool. It is used not only to cut various materials or grind surfaces. Many craftsmen sharpen drills, screwdrivers and other tools with them. They also did not ignore the chains of gas and electric saws.

Note! This type of saw sharpening is unsafe, because the saw teeth are brought by hand to a rotating circle mounted on the angle grinder shaft.

The shaft rotates at a fairly high speed, and it transfers a serious load to the chain. And this is not the only disadvantage, here are just a few of them:

• uneven sharpening of the teeth in terms of maintaining the angle and thickness of the layer being removed;
• the ability to cut through the connecting element (eye) that holds the chain links together;
• difficulty in adjusting slices to the required parameters.

The very process of sharpening with a grinder is that the power tool is clamped in a vice. We must ensure that it does not move or vibrate. They try to secure the grinder so that the disc is in a vertical plane. If you have experience, then you can do everything the other way around, that is, secure the saw in a vice, and bring the grinder to the chain with your hands. Both methods are unsafe.



Which method is easier is clear and without comment. Using simple guides and files makes it possible to sharpen a saw chain at home in quiet conditions. But this option will take time. Ideally and with a guarantee, everything should be done in a technical service, where the teeth will be sharpened on an electric machine with the required angle of inclination. Such a service is inexpensive, the main thing is that such a service is close to home.

How to properly sharpen saw chains

Chainsaws are one of the main tools that a gardener cannot do without. There are gasoline and electric saws that are indispensable for performing complex and regular work on sawing and felling trees.

The Foresta website offers a wide range of gardening equipment, including chainsaws and power saws for working with hardwood trees. The power of the devices is enough for use throughout the day.

The tools are intended not only for household work, but also for performing tasks in the construction or forestry industry. You can purchase products in Ukraine through the website or in company stores.

The performance of electric saws and chainsaws depends on the correct operation of the device, including the saw set and chains. A sharp, properly sharpened chain is the key to efficient and safe operation. To sharpen it, you can use the services of specialists. However, you will have to sharpen your tools regularly, so the best option is to find out how sharpening is carried out and do it yourself, without involving specialists.

Tools for sharpening saw chains

Professionals will tell you that a sharp chain is more important than a strong engine. There is no exact time when the part needs to be sharpened. It all depends on how often you use electric and gas tools.

The first sign of a failure is its slow operation and a large amount of dust. When cutting with a sharp electric saw or chainsaw, the sawdust will be square; otherwise, it will resemble small needles.

There are many devices for sharpening chains of electric saws and chainsaws, let's look at the main ones.

Professional chain sharpening devices allow you to sharpen your tool as quickly and efficiently as possible. However, not every gardener will want to buy such a setup. It is much easier to sharpen a part using tools that are found in every craftsman’s home.

As for hand tools, you will need a flat file, a round one for processing the cutting teeth, and a hook for removing sawdust. If the cutting part of the teeth is completely deformed, then sharpening the chain with a file is quite problematic, and the work will take a lot of time. The optimal replacement is the use of manual machines. The process occurs several times faster: 3–5 movements are enough. The main condition is to set the operating parameters correctly.

One of the most popular and inexpensive devices for sharpening chain saws is a grinder. Any craftsman can find such a tool in his home, and sharpening the equipment is very easy. Let's take a closer look at each method.

How to sharpen an electric and chainsaw chain with a file

Sharpening electric saws and chainsaws is done in the same way, and the main advantage of this method is cost-effectiveness. A file can be found in every home, and you can buy it very inexpensively, even if you choose a diamond file for sharpening a chainsaw chain.

We will tell you below how to choose a file for sharpening a chainsaw chain. You'll need:

• A round file for sharpening a chain, the diameter of which should correspond to its width. If the chain size is 1.3 mm, select a 4 mm file; with size 1.6, the diameter of the file for sharpening the chain is 5.2 mm.
• Flat is used for cutting tooth stops.
• A sharpening pattern or template is attached to the part to be ground and used to guide the abrasive tool.

Sharpening a chainsaw chain is done manually and consists of the following steps:

• First you need to firmly secure the chain. The better you fix the part, the easier it will be to work.
• The work is performed at a certain angle, without changing it throughout the entire process.
• The file should not protrude above the tooth more than one-fifth of its thickness.
• You only need to apply pressure on the file when moving forward.
• To ensure that each tooth has the same sharpness, you must rotate the file regularly and perform the same number of movements each time.
• If the teeth are of different lengths, grind them all down to the size of the shortest one.

How to sharpen a saw chain with a grinder

Not every chain can be sharpened by hand, especially if the tool is very dull and sharpening is needed to correct serious flaws. The grinding process takes only a few minutes, but requires certain skills. To sharpen the equipment, you do not have to remove the chain; the work is done on the body. Use a 2.5 mm metal disc, and sharpen at minimum speed, processing the teeth one by one.

It is important to follow safety precautions, be sure to use goggles and gloves. You can purchase personal protective equipment on the Foresta website. Accessories are used to protect eyes and hands from external influences, are designed for safe work and will be needed not only to sharpen chain saws, but also when performing other gardening and repair work.

Manual chain sharpening machine

Using a manual chain sharpening machine guarantees efficient and precise results. However, this method is quite long and tedious. The process occurs in several stages:

• It is necessary to loosen the clamp that holds the chain.
• For accurate and safe operation, securely fasten the part.
• Next, set the appropriate sharpening angle.
• The level of sharpening is determined by the degree of the most dull tooth.
• After completion of work, the chain must be cleaned and placed in oil.

To make work easier, instead of a machine for manually sharpening a chainsaw chain, it is better to use an automatic device - a machine that is used in woodworking enterprises and workshops.

Professional sharpening machines for chain saws

A professional machine for sharpening chains of electric saws and chainsaws will allow you to quickly and efficiently service the device. Many people prefer to do without it, carefully filing each tooth with a file. However, an electric chain sharpener is easy to use and will help make your work as easy as possible. Chain sharpening machines are designed for long-term tasks; sharpening is easy with a machine, but whether it is worth buying a device exclusively for home use is up to you to decide.

Sharpening a chainsaw chain on a machine is not difficult: you need to fix the chain in special guides, adjust the width of the groove, select the correct angle and lower the sharpening disk. We move the chain along the holder, clamp it and process each tooth.

Sharpening the chain of petrol and electric saws occurs on the emery stone of the machine. This method does not require professional skills and takes very little time. Its main drawback is the financial costs that will have to be allocated to purchase the device.

Therefore, gardeners more often use hand tools, machines or a grinder. When choosing a tool, consider the degree of dullness, the time required and the desired result.

At the same time, be sure to use protective equipment (goggles, gloves or a face shield) for safe and productive work.
