How to sharpen a chainsaw for a Stihl chainsaw

Sharpening angle of chainsaw chainsaw calm on the machine

ANY CUTTING TOOL, NO MATTER SHARP AND HARD IT IS, WILL BE DULLED IN THE PROCESS OF WORK. TO PRESERVE ITS ORIGINAL PERFORMANCE, THE USER HAS TO PUSH HARDER ON IT WHILE OPERATING, WHICH INCREASES FRICTION.

THIS USUALLY RESULTS IN INTENSIVE HEAT GENERATION IN THE CUTTING AREA, AND WHEN CUTTING WOOD, SMOKE AND A BURNING SMELL MAY APPEAR. TO ELIMINATE THIS SITUATION, IT IS NECESSARY TO PERIODICALLY SHARPEN THE CUTTING TOOL TO RESTORE ITS ORIGINAL PROPERTIES.

HOW TO MANUALLY SHARPEN A CHAINSAW YOURSELF? SERGEY GEKMAN, STIHL AND VIKING PRODUCT TRAINER, TELLS US ABOUT THIS TODAY.

About the design of the chain saw saw set

First, a few words about the design of the saw chain. All modern saw chains are three-link and are designed on the same principle. They consist of driving links, connecting links, as well as left and right cutting teeth (installed alternately).

Over time, it is the cutting links that become dull, even though STIHL makes them only from wear-resistant chromium-nickel steel. The chain is put on a tire with a guide groove along which its leading links slide.

Note that in STIHL chains, the supporting surface adjacent to the bar is induction hardened during manufacturing to increase wear resistance.

The tires have perfect symmetry, allowing them to be flipped, swapping bottom and top, allowing the load to be distributed evenly on both sides.

Tools for home and garden, handicrafts, etc. prices are very low

The chain is driven by a drive sprocket on which the chain is placed. During manufacturing, each chain is necessarily subjected to pre-stretching, which reduces elongation during initial use to a minimum, increases its service life and reduces wear.

Circuit Parameters

The main geometric parameters of the saw chain are pitch, profile height and shape of the cutting tooth, thickness of the drive link, number of links. The pitch is half the distance between the centers of three consecutive rivets.

It is usually measured in inches, and each has a symbol (see table 1). Based on the height of the tooth profile, saw chains are divided into low- and high-profile. Thus, for powerful chainsaws, STIHL provides Rapid chains with a higher tooth, and for less powerful chainsaws, Picco chains with a lower tooth. The number of links determines the length of the chain, depends on the power of the engine installed in the saw, as well as the type of work performed and corresponds to the size of the tire.

The thickness of the drive link is measured in millimeters (mm) and must correspond to the width of the groove of the tire used (c/i. Table 2). The last number of this thickness is stamped as a symbol on each drive link of the chain.

Saw chains may also differ in the shape of the cutting tooth. Chains produced by STIHL have two such forms - Micro (M), Super (S). Without going into the intricacies of the design, we note that a saw chain with a Micro cutting tooth shape is universal; it combines high cutting performance, ease of use, long service life and simple maintenance.

Meets the requirements of construction, agriculture and forestry. The Super tooth shape saw chain combines maximum cutting performance, high plunge-in efficiency and low feed force to meet the highest demands on professional forestry tools. These chains cut faster and are good for cutting hard or frozen wood. There are certain features when sharpening a Super saw chain.

In addition, STIHL has a Duro saw chain with carbide-tipped teeth. It combines the highest wear resistance, ease of use and good performance. Stable when working with dirty wood or in short contact with the ground, when sawing formwork boards or scaffolding after finishing work.

Highly effective when used in forest areas damaged by fire. Duro chains last up to 10 times longer than non-carbide-tipped saw chains. Such chains are much more expensive, and are sharpened with an electric sharpening machine with a diamond sharpening wheel in specialized service centers.

The cutting teeth work on the principle of a plane: they cut chips from the wood. The depth of penetration of the cutting tooth into the wood and thus the thickness of the chips is determined by the distance between the depth stop and the upper part of the cutting tooth.

If this distance is not enough, then the saw chain will not capture the chips (that is, cut), but will only slide along the wood. Conversely, the greater the height difference between the stop and the tip of the cutting tooth, the thicker the chips, but at the same time the greater the vibration produced by the chain, and the higher the load on the drive mechanism.

Therefore, it is necessary to achieve an optimal balance between chain vibration and performance, and in all STIHL saw models this ratio has been selected.

How to determine when it’s time to sharpen a chainsaw chain

Frequent use of a chain saw leads to rapid dulling of the cutting teeth, and when abrasive particles (for example, earth) enter this process accelerates. Sometimes it is necessary to restore the cutting ability of a saw several times during one working day: with timely sharpening, less steel will have to be removed each time, which will increase the service life of the entire cutting set as a whole. We list the most characteristic signs of a dull chain:

• — the saw does not cut into the wood itself, requiring significant pressure on the motor block;
• — instead of large chips, the saw chain throws out small sawdust;
• — the appearance of smoke and a burning smell when sawing, despite the impeccable operation of the oil pump and sufficient chain tension;
• — the saw “leads” to the side due to uneven wear of the cutting teeth;
• — when sawing, the chain “beats” and “jumps,” which can be caused by the small distance between the tops of the depth stops and the corresponding cutting edges.

In addition, special lines are applied to the cutting links of STIHL chains - these are wear markings. If the chain wears down to these lines, the chain needs to be replaced.

Practical recommendations for sharpening the chainsaw of a Shtil chainsaw

Sharpening a saw chain, if you have the appropriate knowledge and skills, is not difficult, but it requires compliance with certain rules. Let's look at the most useful and necessary ones.

When working with a saw for a long time, you have to periodically sharpen its cutting part during the day, since all cutting teeth must first of all have the same length, sharpening angle and position of the depth stop.

To do this, we first find the shortest tooth, take it as the starting point, and during the sharpening process we adjust all the other cutting teeth of the chain to its length. If it is in the right row of teeth, then fix the guide bar in a vice with the end sprocket to the left, but if in the left row, then turn the guide bar with the end sprocket to the right. Then we place this tooth in the sharpening zone and turn on the chain brake. Sharpening is carried out with a round file of a certain diameter depending on the chain pitch

Proper sharpening of a chainsaw chain with a file

The chain is considered an important part of any chainsaw, because with its help all work with trees is performed. Therefore, when using a chainsaw frequently, the chain needs periodic maintenance, and one of these points is sharpening the chain with a round file.

How to determine the need for sharpening?

Everything is very simple, when using a chainsaw, look at the sawdust obtained from the work; if it looks unusual and looks like dust, the chain most likely needs to be sharpened or completely changed. It all depends on the duration and correct operation. Please note that you need to check the suitability of the chain on dry trees, do not use wet wood.  

Also, if you cut in the longitudinal direction, you can determine chain wear by detecting gross defects on the cut surface in the form of chips of wood and tears at the saw site. Other noticeable signs include:

• While moving to the top edge from the chainsaw workplace, you notice a different radius;
• If there is a cut, the chainsaw may vibrate during the process, increasing noise;
• Resistance increases when you first try to start sawing wood.

Be careful when working with unsharpened chains, otherwise you will experience overheating of the chainsaw and the appearance of defects on the cylinder.

How to sharpen a chainsaw chain?

If you do not want to change the chain several times a year, you can perform the sharpening procedure yourself using simple tools. The main methods include:

1. Machine. Usually available from specialists or special service centers, so the procedure, although effective, is not so accessible. The machine is also used for those chains that have heavy wear;

2. Bulgarian. It’s better not to try without experience; sharpening with a grinder requires certain knowledge. Otherwise you will damage the chain;

3. File. The simplest and most popular tool for sharpening, its small size allows you to carry the file with you and sharpen it right on the job site.  

How to sharpen a chainsaw chain with a file

Although the file is inexpensive and easy to use, for chainsaw chains you will have to acquire a special type. To work, you will need two types of files - round and flat. The standard work kit looks like this:

• round file with a permissible diameter of 4.5-5 mm;
• flat file for changing the limiter;
• a holder with lines, the task of which is to position the chain on the permissible upper edge;
• hook, needed to remove sawdust and working shavings.

Please note that the diameter of the file is selected so that it corresponds to the rounding of the working part of the saw tooth. If you use chainsaws for domestic purposes, round files with a diameter of 4 and 4.8 mm will be the most optimal. More powerful and professional chainsaws will require a round file with a diameter of 5.2 or 5.5 mm.  

Important: in order for the chainsaw to cut correctly in the future, in addition to sharpening the cutting edges of the teeth, you will have to change the limiter responsible for the depth of cut. Otherwise, the chain will not be able to cut to the proper depth, which will result in longer, harder work with the wood. The limiter is adjusted using a flat file described above.

Files for sharpening chainsaw chains Shtil 180

First it is important to buy the right file for the job, if you are using a Stihl 180 model, the round file will have to be selected based on the chain pitch (0.325 inches), the presence of serrations and the length of the file itself. Based on the GOST 1465 standard, round files are classified by length by number. The following files are ideal for the Shtil 180 brand:

• No. 4 - working length 200 mm;
• No. 5 - working length 250 and 300 mm.

The second option is more suitable, because the longer length will make the sharpening procedure convenient and effective. 

Notches on round files can be of two types - notched and cut. We recommend choosing notched ones due to the smaller cutting angle range. The most suitable files are those made from tool steel; we recommend products from the Zubr brand. The manufacturer creates them specifically for handmade work and offers many different sizes.  

Chain sharpening procedure

First of all, place the chainsaw on a flat surface; at home it can be a table; when working in the forest, a large block of wood is perfect. It is important that the chain is tensioned when sharpening, otherwise the procedure will be a failure. Sharpening takes place in the following stages:

1. A round file is installed in a perpendicular direction when moving the teeth on the chain in a vertical position; if the teeth are in a horizontal position, the file is installed at an angle from 15 to 200 degrees. For horizontal teeth, you can use a holder.

2. For the procedure to be successful, when installing the file into the tooth mouth, make sure that it is installed just above the edge; 1 mm is enough;

3. The third stage is installing the holder on the tooth. The lines on such a tool will show the correct direction of movement of the file in a horizontal position.

4. Once positioned correctly, you can make a couple of strokes with the file until metal shavings form. The shavings are removed with a previously prepared hook;

5. You need to sharpen the chain in a position away from you; with the correct choice of file diameter, the notches should fit smoothly into the tooth.

6. For better efficiency, sharpening is carried out through 1 tooth, in the opposite direction the process is carried out along the missing teeth.

7. It is important to always apply a little pressure on the file during the procedure, this will increase the amount of shavings removed and speed up the process.

Manual machine

For those who do not like to go into details and do the above sharpening of the chain with their own hands using a file, you can give preference to a manual machine.

This machine is based on the same file and can be replaced with a suitable diameter in a few seconds. This machine is attached directly to the tire; if necessary, there is a function for adjusting the sharpening angle.

The machine is capable of creating a stop that will hold the tooth while sharpening. A good device that is low cost and easy to use.  

The machine is used by both novice craftsmen and experienced workers with chainsaws. The cost of the machine is significantly higher than that of expensive electric models. It is recommended to purchase a standard Stihl manual lathe.

Important features when sharpening

If you work with a file and are ready to sharpen it yourself, pay attention to the following nuances and recommendations:

• A standard file will sharpen a chain a maximum of 2 times;
• Cleaning up shavings is most convenient with a crochet hook;
• Mechanical sharpening with a file is faster and cheaper than using a grinder or a machine;
• To determine the height you will need a template;
• You can buy a file for sharpening a chainsaw at chainsaw stores;
• It is advisable to sharpen teeth from problem areas first.

At first glance, the procedure seems complicated, but after the first successful attempt, you will understand how to properly sharpen a chainsaw chain right at your workplace.

Sharpening Chainsaw Chains Calm Manually

Do-it -yourself chainsaw

The chain tooth planes wood like a plane, and the thickness of the chips is adjusted by the height of the stop.

The intense work of the saw leads to rapid dulling of the chain. Several sharpenings may be required during the first day. The problem is also made worse by the fact that the tooth quickly becomes dull when it meets the ground. It’s enough to hit the soil with the tire once or twice, and you can stop working - the chips become small and the saw stops going deeper into the tree.

The earlier dull teeth are sharpened, the less material needs to be removed when sharpening, and as a result, the service life of the saw chain is longer. Finding the moment when sharpening is quite easy. The main feature is the feed force.

correctly sharpened chain is pulled into the cut even with a slight pressure. If, on the contrary, the chainsaw is forced to cut by increased feed force, then the teeth have become dull.

dull chain can also be recognized if, instead of large thick chips, only small chips fly out of the cut.

In this situation, the chainsaw must be sharpened urgently. Do not cut with a dull or defective saw chain - the result will be severe stress on the body, high repetitive stress, and poor cutting results. In addition, this means a decrease in productivity, high fuel consumption and increased wear on all components of the chainsaw.

Chain teeth parameters

To achieve good cutting parameters, the tooth blades are given certain angles. The back of the tooth falling at an angle backwards forms the rear corner of the upper blade . This angle is needed to cut the upper blade into the wood.

The back-tapering blade of the tooth forms the rear angle of the end blade. This angle is needed for side cutting of chips.

The edge of the end blade forms a rake angle with the sliding surface of the cutting link. Rake angles for different types of chains vary from 60 to 85°.

The rear angle of the upper blade describes the backward tilt of the upper blade .

This angle is measured relative to the sliding plane of the cutting link and, depending on the type of saw chain, ranges from 50° to 60°. The top blade is the main blade, and the back corner of the top blade is the most important angle. The back angle of the upper blade is difficult to measure; its correct value is formed by observing other prescribed values.

The sharpening angle or leading angle is obtained by measuring from the top cutting edge at right angles to the guide bar.

The sharpening angle can be changed depending on the application. The basic rule: the larger the sharpening angle, the higher the cutting performance when cutting unfrozen soft wood. Reducing the sharpening angle when cutting frozen and/or hard wood makes the saw run smoother and reduces vibration. However, sharpening angles of more than 35° and less than 25° should be avoided (the exception is rip saw chains, in which this angle is 10°).

The rake angle, sharpening angle and top blade change during sharpening. These angles have a decisive influence on the cutting ability of the chain. Be sure to observe the prescribed values.

A depth limiter is located on each cutting link in front of the tooth blade. The difference in height between the top edge of the depth stop and the leading edge of the back of the tooth is defined as the depth stop .

The depth of cut of the upper blade into the wood (chip thickness) and thus the productivity on the distance of the depth stop depth stop distance is set depending on the chain pitch and type of design. Normally it should be 0.5-0.8 mm, more often 0.6 mm.

Higher values ​​will make the chainsaw more prone to kickback, excessive grip and chain vibration. Low values ​​lead to poor performance.

Since the distance of the depth stop decreases with each sharpening of the saw due to the reduction in the upper edge of the tooth, the depth stop also needs periodic filing - after 5-10 sharpenings of the chain.

How to sharpen chain by hand without removing it from the bar with a round file. Stihl. with your own hands

Many people don’t know how to sharpen the teeth on a chainsaw chain , but it’s quite simple. round file 4.8 mm and that’s it.

Sharpening a chain on a chainsaw with your own hands

sharpen a saw chain in the best way can be seen in this video. Continued

Chain sharpeners

The round file holder has lines that allow it to be positioned correctly relative to the chain. The holder is installed on the tooth being sharpened in accordance with the orientation lines. In this case, the plate itself rests on the upper edge of the tooth and the depth stop, and the file is located under the cutting edge.

Using a holder ensures that the file rests on the tooth at the correct height. There are different holders available for different saw chain pitches. The correct choice of holder in combination with the correct file diameter ensures that the file extends 1/5 of its diameter above the back of the tooth. Use only special files for sharpening saw chains.

Before sharpening chain , it is advisable to secure the bar. When sharpening, it is necessary, while maintaining the position of the holder and pressing the file against the edge being sharpened, to make several (2-3) turning movements away from you.

There is no need to try to press the file too hard; movements should be smooth and measured. Turn the file regularly to avoid one-sided wear. All other teeth are sharpened in the same way.

It is more convenient to first sharpen the teeth of one direction, then change the position and do the same with the teeth of the other direction.

When sharpening all teeth, make the same number of file strokes using the same pressure. This will ensure that the teeth have the same length. All cutting teeth must be the same length. Different tooth lengths cause uneven movement of the chain and the formation of cracks in it. If the tooth lengths are not the same, all cutting teeth should be filed to the length of the shortest tooth.

After several sharpenings of the cutting teeth, the depth stop is ground off. To do this, a template is placed on it so that the stop fits into the slot, and the tip protruding from the slot is ground off with a flat file.

Such sets, with different configurations, are sold in many stores that sell tools, for example, various sets and individual files are sold here (it’s better to buy through an online store, because in a regular store of this network the price may be higher).

The principle of using another kit for sharpening chainsaw chains is no different from the first, although its design is different.

A round file is also used to sharpen the cutting tooth, and a flat file is used to sharpen the depth stop . A special template provides sharpening parameters for both cutting teeth and stops.

In the first case, it is placed on the chain so that it fits into its slots. The file, placed on the template and brought under the cutting edge, rests on the guide rollers.

The direction of movement of the file should be parallel to the side edges of the template.

When grinding the stopper, the template is applied so that the stopper fits into the slot, next to which it says SOFT (for soft wood) or HARD (for hard wood). As in the case of the first device, grinding is done with smooth, even movements of the flat file away from you.

Chainsaw chain sharpening machines

Stihl produces two modifications of manual machines - stationary FG 2 and mobile FG 1, installed directly on the tire. There are analogues from lesser-known companies, comparable in price to the simpler devices described above, for example this

The working part of these devices is structurally reminiscent of a bow saw, into which a long round file is inserted instead of a saw blade. FG 1 and FG 2 not only sharpen chains, but also straighten them, adjusting the length of the upper edge of all teeth to the same size - according to the smallest tooth, which is taken as the control one.

A rather complex configuration mechanism allows you to set all the necessary parameters. Sharpening is done in 2-3 movements, after which they proceed to the next tooth, maintaining for it all the settings that were made for the control tooth. This ensures the same sharpening parameters for all teeth.

When grinding the stopper, the round file changes to a flat one.

An electric sharpening machine for chainsaw chains is simple and easy to use. It has an adjustment system that allows you to set the chain at the desired angle and bring the disc exactly to the edge to be sharpened. There are machines that automatically clamp the vice when lowering the disk onto the chain .

Instructions for sharpening STIHL chains for chainsaws

Normal and productive operation of a chainsaw can only be ensured with proper operation of the saw set and, above all, the saw chain. The fundamental rule for any chain saw owner should be to work only with a sharp chain. Never use dull chains for sawing.

To ensure that the chain on your saw is always straight, we recommend that you learn how to sharpen it correctly. Only a properly sharpened chain can always ensure efficient, safe and precise cutting.

Professionals know that even the power of a chainsaw engine does not affect work performance as much as a sharply sharpened chain.

How often should you sharpen your chain?

There are no standards defining clear timing for sharpening saw chains. The main indicator of the need for such a procedure is the elementary dulling of the chain. It depends on how often the chainsaw is used, what materials have to be cut and how accurately the rules for using the tool were followed. An indicator of a dull chain is a slower sawing speed.

The need to sharpen a chain may also arise if it was initially sharpened incorrectly. Signs of this may include various deviations from the norm during cutting, for example, the chain “leads” to the right or left.

Such a chain should also be sharpened, but before sharpening you need to additionally check the sharpening angles on each tooth. Craftsmen can determine the quality of sharpening of a cutting chain by the chips.

With a properly sharpened, sharp chain, the shavings are always uniform, and the sawdust is approximately square in shape, but with a dull chain, there will be a lot of dust in the shavings; Sparks may also fly out.

ATTENTION! If you cannot sharpen chains yourself, then you should entrust this process not to an ordinary sharpener, but to a chain sharpening specialist. Such specialists are always at your service in the “Service Center” of the KHK company.

Choosing a file for sharpening a saw chain

The diameter of the round file is selected depending on the height of the cutting tooth and the pitch of the saw chain. marking is located on the outer wall of the depth gauge.

The chain should be sharpened at home with round files of the following diameters:► for chains with parameters of 1.1 mm and 1.3 mm (chain link width) and a pitch of 3/8″ (such chains are equipped with STIHL MS 170, 180, 181, 211 chainsaws , 230, 250) - a file with a diameter of 4 mm is used;► for chains 1.6 mm, 3/8″ (saws STIHL MS 290, 361, 440, 441) - a file of 5.2 mm is needed;► for chains with a width links 1.5 or 1.6 mm and pitch 0.325″ (for chainsaws MS 261C-MQ, 271, 291) round files with a diameter of 4.8 mm are used;► for chains 1.1 mm and pitch 1/4″ (cordless saws MSA 120C, 160C, 160T, 200C) a file with a diameter of 3.2 mm is used;

► for chains 1.6 mm, 0.404″ (saw MS 880) and for sharpening chisel-shaped discs on professional Stihl lawn mowers, use a file with a diameter of 5.5 mm.

NOTE! Finding and purchasing a suitable round file for sharpening your STIHL chain is quite easy. Any files and their prices are presented in our “Catalogue” , they are always available in our company stores, you can choose the one closest to you using the map.

Chain sharpening equipment

The necessary tools for sharpening a chain are round and flat files. A round file is inserted into a holder that is already marked with marks for the correct sharpening angle. A flat file is used to grind down the stop tooth.

Experts recommend that the best option is to have a sharpening kit for sharpening work, which already contains tools that are suitable specifically for sharpening your model of saw (it is better to purchase it immediately when purchasing a saw). You can always get advice on choosing a chainsaw, cutting accessories and sharpening tools from the managers of our company “KHK”.

Standard sharpening set includes:

1. A holder (a device for securing a round file), on the bar of which the sharpening angles of the cutting saw teeth are pre-marked.

Note : It should be borne in mind that when sharpening the cutting teeth of the chain with only a round file, without a bar, you will need to determine this sharpening angle (usually 30 degrees for most chainsaw models) approximately by eye and, if you sharpen the teeth at the wrong angle, the chain during operation it will “lead” to the left or right. The use of a holder allows the file to grind down two tooth edges in one pass.

2. Filing gauge (template). With its help, it is easy to determine the accuracy of grinding of the limiter tooth.

3. STIHL branded flat file with a fine notch, which is specially designed for grinding off the limiter tooth.

a vice when sharpening . They can make your work more convenient in many ways. By holding the tire in a vice, you can free your hands for other operations.

Chain sharpening technique. A little theory

The principle of operation of chain links is similar to the operation of small planes. The quality and productivity of sawing wood is determined by the difference in the height of the cutting tooth and the stop tooth . This difference in height between the teeth determines how deeply the tooth will cut into the wood.

The figure shows the elements of the cutting tooth of a saw chain. The cutting tooth consists of a tooth base (1), a depth stop (5) and a tooth blade (2), with an end blade (4) and an upper blade (3).

The end and top blades are located at a certain angle to each other. This angle is decisive for optimal cutting power. It can only be achieved when the sharpening angle is precisely adjusted.

The stop tooth should be 0.45-0.8 mm below the cutting tooth (depending on the brand of chain).

On each tooth, two marks are laser-etched (on top and on the side), which show the maximum wear of the tooth and at the same time indicate directions. At the same time, they should sharpen the teeth.

On the plates, which are the connecting links between the teeth, a triangle is extruded, showing the direction of movement of the chain. There is also a slight concavity at the bottom. When putting the chain on the bar, a small gap is created between the bar and the shape of the connecting plate.

This clearance is an indicator of chain wear . Once it is practically no longer visible, the chain must be replaced with a new one, even if the cutting teeth remain in good condition.

This should be done because as a result of abrasion of the connecting links, the area of ​​​​contact between the chain and the guide bar will increase, which can result in rapid abrasion of the bar itself.

On the chain links there are oil receivers - special hole channels that ensure a constant supply of chain oil to the rivets. In their lower part there is a semicircular oil intake. It serves to capture and pull the chain oil throughout the bar.

Note: During operation, be sure to ensure that the hooks are not worn out, otherwise the links will not be able to capture the chain oil and supply it through the channel to the rivets. As a result, the saw set and bar may overheat, the chain will stretch, and this may lead to its rupture.

Cutting teeth.

Sharpening of cutting teeth should be done as they become dull.

When sharpening chain teeth, your actions are as follows:

— place a file holder with a file on the chain. The arrows on the holder (30 degrees) must be parallel to the tire!.

— sharpen the teeth with light, measured movements, pressing forward should only be done at a right angle to the saw bar.

— sharpen the teeth first on one side, then on the other; professional craftsmen believe that this achieves a better effect and is much more convenient.

During operation, as the teeth become dull, it will be enough to just sharpen the teeth a few times with a holder. Attention: movements of the holder should only be from yourself, and not in both directions! In this case, it is necessary to periodically rotate the file to ensure even abrasion.

If the teeth are already completely worn out and blunt, then before sharpening you need to measure each tooth with a caliper and find the shortest one in the chain. All teeth must be ground to the size of the smallest tooth .

When working, you must always check the sharpening angles of the teeth (top angle - 30 degrees for all brands of chains, side angle - 75 degrees for household chains and 60 degrees for professional ones).

Angle deviations of no more than 2 degrees in both directions are permissible.

After sharpening the teeth, you must attach a template (caliber) to each tooth and check the height between the cutting tooth and the stop tooth . If the limiting tooth is at the level of the template, then the height is normal.

When the tooth is lower than the template , the height is higher than recommended and the cutting tooth will remove more wood than it should (the load on the chain and engine increases).

Therefore, using a holder with a file, you need to sharpen the cutting tooth again (reduce it).

If the limiter tooth is higher than the template , then the height is lower than recommended and, accordingly, this tooth does not cut the wood. For correction, a flat file with a fine notch is used. They need to grind down the limiter tooth to the level of the template. After this, parallel to the applied mark, make a rounding for a smoother entry of the tooth into the wood.

How to sharpen a Stihl chain correctly and quickly: instructions from the manufacturer

ANY CUTTING TOOL, NO MATTER SHARP AND HARD IT IS, WILL BE DULLED IN THE PROCESS OF WORK. TO PRESERVE ITS ORIGINAL PERFORMANCE, THE USER HAS TO PUSH HARDER ON IT WHILE OPERATING, WHICH INCREASES FRICTION.

THIS USUALLY RESULTS IN INTENSIVE HEAT GENERATION IN THE CUTTING AREA, AND WHEN CUTTING WOOD, SMOKE AND A BURNING SMELL MAY APPEAR. TO ELIMINATE THIS SITUATION, IT IS NECESSARY TO PERIODICALLY SHARPEN THE CUTTING TOOL TO RESTORE ITS ORIGINAL PROPERTIES.

HOW TO MANUALLY SHARPEN A CHAINSAW YOURSELF? SERGEY GEKMAN, STIHL AND VIKING PRODUCT TRAINER, TELLS US ABOUT THIS TODAY.

What is the sharpening angle of the Stihl chainsaw chain?

In the process of working with a chainsaw, the chain of any, even the highest quality tool, over time loses its original sharpness and needs to be sharpened. By what signs can you understand that the chain of an electric saw or chainsaw has become dull and it’s time to sharpen it?

Below are the main signs that it is time to sharpen your chain:

• during operation, the saw loses stability, breaks out of the hands and vibrates strongly;
• a chainsaw or electric saw produces only small chips and does not produce large chips;
• the saw part gets stuck in the material, sawing cannot be done efficiently and quickly;
• the chainsaw does not deepen into the wood on its own; in order to make a longitudinal cut, the tool has to be “sinked” into the material with your hands, applying force and pressing the blade;
• during sawing, a curved cut is formed;
• the chainsaw heats up quickly and strongly;
• chain wear occurs much faster;
• fuel consumption increases.

If you notice several of the described signs on your home tool, then it's time to sharpen the chain.

The original chainsaw chain can be sharpened several times, it will retain all its operating properties - cutting sharpness, cut quality, rotation speed along the bar.

A few important tips that will help you avoid sharpening your chainsaw chain longer:

• do not use a new chain with an old sprocket and vice versa;
• if during operation of the chainsaw you have already sharpened two chains, replace the sprocket with a new one;
• the chain must be run-in before full operation of the chainsaw with normal load (run-in is done immediately before sawing, 1 minute at low speeds, and then 1 minute at medium speeds);
• after the new chainsaw chain has cooled, you should check the degree of its tension;
• always use chain saw lube and high-quality oil;
• maintain the normal tension of the links, because during operation the chainsaw is often tilted in different directions, which increases the likelihood of the chain slipping off the bar;
• control the position and direction of the cut depth limiter; after the 3rd or 4th sharpening, check the limiter parameters.

Characteristics of chain teeth

Chain teeth have several important parameters. These parameters include:

• cutting link device (consists of a base attached to the chain, a tooth blade with two cutting edges, a depth limiter that controls how deeply the blade cuts into the tree, an end and top blade), the cutting action is performed not by the chain itself, but by the links, that is , teeth. They move on a chain, as if on a base, on a tree, and the link cuts the tree;
• The angle of the end blade that allows the chain to cut the wood (it is because of this angle that wood chips are formed when cutting).

To properly sharpen a chain, the owner needs to know:

• chain metal type (soft, hard, medium);
• chain pitch;
• depth stop distance.

How to properly sharpen a chain depends on these two parameters. The softer the metal of the chainsaw, the more carefully you need to handle the file when sharpening by hand. The upper edge of the file during sharpening should be located at an angle of 90° in the vertical plane and 30° or 10° in the horizontal plane.

about the sharpening angle of a chainsaw chain

This video shows how to properly sharpen a chainsaw chain and shows the main parameters of saw chains.

The following video is from a chainsaw owner on how to sharpen a chainsaw chain with your own hands

Rake angles for different types of chains can range from 60 to 85°. The greater the degree of rear angle of the upper chain blade, the more it will be inclined back, the average value of this angle is from 50° to 60°. For the cutting process, the most important indicator (degree) of the rear angle of the upper blade, and the upper blade itself is very important for high-quality sawing.

The main condition when sharpening the chain of a chainsaw or electric saw: cutting performance is directly proportional to the sharpening angle, that is, the higher it is, the better the chainsaw will cut the material. The smaller the sharpening angle, the smoother the tool will move, and the less vibration there will be during operation.

Avoid sharpening angles greater than 35° and less than 25°. In chains for rip sawing, an exception for the sharpening angle is allowed; in these chains, the sharpening angle can be 10°.

Sets of necessary tools, templates and accessories for sharpening chains

The most popular chain sharpening tools:

• round file;
• flat file;
• holder;
• template for depth gauge;
• hook for removing sawdust.

The sizes of files for sharpening chainsaw chains vary, but in ordinary life, for domestic needs and home use, files with diameters of 4.0 are recommended for sharpening chains with pitches of ¼, 0.325″, 3/8″ and 0.404″; 4.8; 5.2 and 5.5 mm. For some chains, cylindrical needle files with a diameter of 3.2 mm are used. For manual sharpening with your own hands, the ideal option would be a file 200 mm long with a diameter of up to 5 mm.

Some manufacturers sell these tools as sharpening sets, or you can purchase them separately. A round file is one of the most popular tools, with the help of which many owners sharpen a chain no worse than on machines. Each set is designed for a specific chain pitch and size. To choose a set for sharpening chains, you need to know these two parameters.

Markings are applied to the holder - they help the chainsaw owner determine the correct angle position for sharpening the chain. The holder is installed simultaneously on the upper part of the stop and the tooth, and the round file is placed under it immediately next to the blade. The holder holds the file at the required height; according to the standards, it should rise 1/5 above the blade.

To sharpen a chainsaw chain at home, the bar is secured with a vice or clamp. It is important to keep the tool still while sharpening. The holder is placed on the marking, and then the file is moved along the chain away from you 2-3 times. Each tooth is treated the same way. From time to time, the file is turned to the other side so that it does not grind unevenly.

For convenience, the teeth are sharpened evenly on one side, after which the saw is turned over and aligned on the other side.

Sharpening begins with the smallest tooth, since the length of the remaining teeth must coincide with it. When the blades are sharpened, the stops are processed. Place the template from the kit on the chain so that the stop fits into the hole, and grind off all protruding edges with a flat file from the sharpening kit.

Sharpening a chainsaw chain with your own hands at home, the correct angle for sharpening the chain of the Shtil device

The guarantee of long-term operation and good performance of your tool is correct and timely maintenance. To make the sawing process comfortable, it is necessary to sharpen chain saws in a timely manner. Blunt teeth can be sharpened by contacting a specialist, or you can do it yourself. The process is simple. But given that the teeth have a non-standard shape, you need to know some nuances and acquire a special tool.

Causes of the problem

A chainsaw is a hand tool that is used for longitudinal and cross cutting of wood. The cutting element of the saw is equipped with teeth with a cutting edge; they are sharpened in a special order. Wood is a relatively soft material, despite this, with intensive use of the chain, the teeth become naturally dull, and small defects and chips appear on them.

These defects lead to a decrease in the efficiency (efficiency) of sawing, a significant weighting is felt, as well as a delay in the process. Do-it-yourself chainsaw edits improve performance. This standard procedure can be performed using various devices.

Circuit State Determination

Pronounced signs of wear on the cutting part of the tool include the following manifestations:

1. When cutting wood, the tool “walks” from side to side.
2. In electric saws, at maximum speeds, the load on the engine is significantly felt.
3. Excessive width and unevenness of the cut is observed.
4. An abundance of small chips appears.
5. The usual cutting time increases and work productivity decreases.

During work, additional efforts must be made; this not only leads to rapid fatigue of the worker, but also increases the risk of tool breakage or chain breakage. Therefore, you should not hesitate to resolve the issue of eliminating defects, and in some cases, replacing the chain.

Options for doing the job

It is important to know how to sharpen a chainsaw chain at home, so as not to delay the process of working with lumber and not break the tool. Sharpening an electric saw chain with your own hands is no different from straightening the cutting element of a saw with a gasoline engine. You can choose one of the available methods:

1. Straightening teeth using a file is the most common and easiest method, which allows you to sharpen directly on the job site.
2. The teeth can be sharpened using the PowerSharp system.
3. Using a special sharpening machine - this method is used by service centers, but it can also be used at home.
4. Using an angle grinder (grinder). This method is unlikely to be used by inexperienced users, since it is rarely used and requires certain skills.

Shtil chainsaw sharpening angle

It is important to maintain the sharpening angle of the rear corner of the upper blade; this can only be done using a template. It is extremely difficult to achieve this in other ways, since its value ranges from 50 to 60°.

The angle of the leading edge can be changed depending on what type of sawing you will be doing. The harder the wood, the smaller the angle, otherwise the edge will bend. The optimal angle values ​​are 1012° for longitudinal cutting, and 2530° for cross cutting.

Its performance depends on which edge angle is used in a particular case.

Editing the chain with a file

Chainsaw chains are sharpened using two types of files: round and flat. The round file must correspond to the rounding diameter of the sawing teeth of the particular chain. For example, to sharpen a Shtil 180 chainsaw with your own hands, you will need a file with a diameter of 4 mm. For other chains of this type, files with a diameter of 3.8 to 4.8 mm can be used. For chains used on professional saws, needle files with a diameter of 5.2 to 5.5 mm are used.

To properly straighten the chain, using only a round file is not enough, because, in addition to sharpening the teeth, it is necessary to adjust the cutting depth limiter. If you miss this important point, the chain will not be able to bite to the required depth into the body of the sawing material, and this will significantly reduce the speed of the work being carried out and will affect the service life of the engine. For this type of sharpening you must use a flat file.

When sharpening, protect your hands with thick gloves and your eyes with goggles.

Useful tips

The following recommendations will be useful in your work:

1. To begin, place the tool on a flat, stable surface—a table or bench works well. If you are in a forest, then just find a wide log or stump. Check the teeth around the entire circumference for chips and other defects: it may turn out that some teeth have broken.
2. Set the saw brake to working condition - this action will block the movement of the chain along the bar. Make sure that the cutting element is taut during sharpening. It is recommended to place a stand in the form of a log or a regular piece of branch under the tire - this way it will not fall through when pressed. You can purchase special clamps to hold the tire in a stationary position.
3. During the sharpening process, the file moves from the inside of the tooth to the outer edge of the edge, turning the file around its axis. In this case, the tool must be moved parallel to a special mark located on the chain. This mark serves as an indicator of the correct sharpening angle of the cutting edge. For the convenience of the process itself, the tooth you are processing should be located in the center of the splint.
4. All sharpening work must be carried out in protective clothing and gloves, since the cutting edge of the teeth is very sharp, so there is a high probability of injury. For uniform sharpening, manufacturers recommend performing the same number of file movements for each tooth; in practice, this recommendation can only be applied to teeth that are not damaged.
5. For easier sharpening, the file can be used in conjunction with a special holder, on which the permissible angles are marked. With the help of such marks, teeth can be sharpened not only for transverse, but also for longitudinal cutting of wood. Using a holder will also be useful for people who, unlike professionals, do not have proper experience in this matter.

Sharpening a chainsaw chain on a machine

The machine is a portable device for convenient sharpening of teeth. It uses the same file as an abrasive tool, which can be changed depending on the caliber of the chain. The device is attached directly to the saw bar. As in the case of the holder, the machine has marks for maintaining the desired sharpening angle, as well as a lock for the tooth being sharpened.

The manual straightening machine is perfect for beginners. The undeniable advantage of such a device is its low price and the fact that with it you can achieve high-quality results comparable to electric sharpening. Externally, the machines may differ, it all depends on the manufacturer, but the results are equally good.

PowerSharp system

With this method, teeth can be sharpened in a matter of minutes, without the need to remove the chain from the bar. The system is equipped with a PowerSharp chain, an abrasive element, a tire and a sharpening device . The process itself consists of 3 simple steps:

1. Installing the PowerSharp bar and chain on the saw.
2. Fasten the abrasive inside the device and install the device on the tire.
3. Press the edge of the saw with the device into any solid body, turn on the chainsaw for a few seconds.

Sharpening a chain on an electric machine

This type of sharpening is used by service centers or enterprises. On an electric machine, the process is significantly accelerated. The machines may have external differences in design, but their sharpening principle is the same: the chain is installed in a special guide groove, which is located on the turntable and has a special stop for fixing the tooth being sharpened. The design of the clamp is equipped with regulators.

Sharpening is carried out by a movable machine, which is equipped with an abrasive wheel and placed at a certain angle. The device has an adjustable cutting depth (for inexperienced users). Once turned on, the operator lowers the abrasive and sharpens the tooth. If necessary, the grinding wheel can be changed. After finishing one side, the chain must be turned over, and the teeth on the other must be sharpened in the same way.

Sharpening with a grinder

This method is less common . This is due to the fact that safety requirements are increased here. But some saw users use it. To sharpen a chain with a grinder, the saw bar must be clamped in a vice so that when the saw brake is off, the chain can move freely. The following actions are performed:

1. A control tooth is selected (the first tooth to be sharpened).
2. The saw brake is set to working position.
3. The grinder turns on and sharpening begins. It is important that the wheel on the grinder is a sharpening wheel and not a cutting wheel.

The disadvantage of this sharpening is that it is very difficult to maintain the required edge angle. It is equally important that there is a risk of damage by the grinder disc to the eye of the link, which may result in the chain breaking during the sawing process.

Despite the fact that sharpening with a grinder is quite feasible, you should still not abuse it. It is better to use the manufacturer’s recommendations and use only certified chain sharpening devices - this will save time and money. Sharpening a chain is not such a complicated process as it might seem at first glance. Even if the first time you manage to do it not very well, do not be upset: rest assured that over time you will gain the necessary skills.

As a conclusion

You learned about simple ways to properly sharpen chain teeth . You should always remember that the cutting element of the saw must be sharp, otherwise the hardware may be damaged, including failure of the power unit. If you notice a lot of wear on the teeth, it is recommended to replace the cutting element as soon as possible. Otherwise, the chain on the chainsaw may break and injure you.
