How To Sharpen A Chainsaw Chain With A File Video
The round file holder has a mowing line that can be positioned correctly in relation to the chain. The holder is mounted on the sharpened tooth in accordance with the line orientation. In this case, the plate itself rests on the upper edge of the tooth and the depth gauge, and the file is located under the cutting edge.
The use of a holder ensures that the file will fit to the tooth at the correct height. There are different tool holders for different chain pitches. The correct choice of holder, combined with the correct file diameter, ensures that the file protrudes over the back of the tooth by 1/5 of its diameter. Use only special saw chain files.
Before sharpening the chainsaw chain, it is advisable to secure the bar. When sharpening, it is necessary, keeping the position of the holder and pressing the file to the sharpened edge, to make several (2-3) turning movements away from you. Do not try to press too hard on the file, the movements should be smooth and measured. Rotate 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 in one direction, then change the position and do the same with the teeth in the other direction.
When sharpening all teeth, file the same number of strokes with the same pressure. This will result in the same tooth length. All cutting teeth must be the same length. Different tooth lengths cause uneven chain running and cracking. If the length of the teeth is not the same, all cutting teeth must be filed to the length of the shortest tooth.
After several sharpening of the cutting teeth, the depth gauge is ground. To do this, a template is superimposed on it in such a way that the limiter falls into the slot, and the tip protruding from the slot is grinded with a flat file.
The principle of using a different set for sharpening chainsaw chains does not differ from the first, although its design is different.
A round file is also used to sharpen the cutting tooth, and the depth gauge is used to sharpen the depth gauge. Flat. A special template provides parameters for sharpening both cutting teeth and stops. In the first case, it is superimposed on the chain in such a way that it falls 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 must be parallel to the lateral edges of the template.
When sewing the stopper, the template is applied so that the stopper falls into the slot, near which it says SOFT (for soft wood) or HARD (for hard wood). As in the case of the first device, the file is seamed with smooth, even movements of the flat file away from you.
Chainsaw chain sharpening with your own hands
The chain tooth planes the wood like a plane, and the chip thickness is adjusted by the height of the stop.
Intense sawing will quickly dull the chain. Several sharpenings may be required within one day. The problem is aggravated by the fact that the tooth quickly dulls when it meets the ground. It is enough to hook the soil with the tire once or twice, and the work can be stopped. The shavings become fine and the saw stops digging into the wood.
The sooner dull teeth are sharpened, the less material needs to be removed during sharpening, as a result. The service life of the saw chain is longer. Determining the moment when sharpening is already required is quite simple. An important feature is the feed force. A properly sharpened chain is pulled into the cut with just a little pressure. If, on the contrary, the chainsaw is forced to cut by increased feed force, then the teeth are dull. A dull chain can also be recognized if only small chips fly out of the cut instead of coarse thick chips.
In this situation, the chainsaw must be sharpened urgently. Do not cut with a dull or defective saw chain. The consequence is high stress in the body, high cyclic load, poor cutting results. In addition, this means reduced productivity, high fuel consumption and increased wear of all parts of the chainsaw.
Chain teeth parameters
To achieve optimal cutting properties, the tooth blades are angled. The back of the tooth falling back at an angle forms the posterior angle of the upper blade. This angle is needed to cut the upper blade into the wood.
The backward tapering blade of the tooth forms the back angle of the end blade. This angle is needed for side cutting of the chips.
The edge of the end blade forms a rake angle with the sliding surface of the cutting link. The front angles for different types of chains vary from 60 to 85 °.
The back angle of the upper blade characterizes the tilt of the upper blade back.
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. This is the most important corner. The clearance angle of the upper blade is difficult to measure, the correct value is obtained by observing other prescribed values.
Grinding angle or entering 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. As a general rule of thumb, the larger the sharpening angle, the higher the cutting performance when cutting non-frozen softwood. Reducing the angle of sharpening when cutting frozen and / or hard wood contributes to a smoother saw blade and less vibration. However, sharpening angles greater than 35 ° and less than 25 ° should be avoided (except for rip chains where this angle is 10 °).
The rake angle, the sharpening angle and the upper blade angle change when sharpening. These angles have a decisive influence on the cutting performance of the chain. Be sure to observe the prescribed values.
A depth gauge is located on each cutting link in front of the tooth scapula. The difference in height between the top edge of the depth gauge and the front edge of the back of the tooth is defined as the distance of the depth gauge.
The depth of penetration of the upper blade into the wood (chip thickness) and thus the productivity depends on the distance of the depth gauge. The distance of the depth gauge is set depending on the chain pitch and type of execution. Normally, it should be 0.5-0.8 mm, more often 0.6 mm. High values will lead to an increased tendency of the chainsaw to kickback, too much grip and chain vibration. Low values lead to a drop in performance. Since the distance of the depth gauge decreases with each sharpening of the saw due to a decrease in the upper edge of the tooth, the depth gauge also needs to be filed periodically. After 5-10 chain sharpenings.
General rules for sharpening chainsaw chains. Chainsaw chain sharpening machines
Stihl produces two modifications of hand-held machine tools. The stationary FG 2 and the mobile FG 1, mounted directly on the tire. There are analogues of lesser-known companies, comparable in price with the simpler devices described above.
The working part of these devices structurally resembles a bow saw, into which a round long 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 top edge of all teeth to the same size. For 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 carried out in 2-3 movements, after which they proceed to the next tooth, keeping all the settings for it that were made for the control tooth. This ensures the same sharpening parameters for all teeth. When sewing the stopper, the round file changes to a flat file.
The electric chain sharpener is simple and convenient 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 sharpened edge. There are machines that automatically clamp the vice when lowering the disc onto the chain.
Manual and electric machines
How to sharpen a chainsaw chain if the cutting edge of the tooth has completely lost its shape due to prolonged work? Files can also be used, but the process will be counterproductive and time-consuming. The best option is to use machine tools, and here you will have to choose, because machines are different. manual and electric.
Stihl manual chain sharpener
Before work, parameters are set, and the processing process is performed much faster than with files: 2-3 movements are enough to sharpen each tooth. Electric machines are also complex to set up, yet work quickly and accurately.
An electric machine can save a lot of time, but not everyone is ready to shell out a large sum for it.
Sharpening of cutting teeth
The question arises: how to sharpen the chain so that all the teeth are evenly even and sharp? The work is facilitated by the use of a metal template, which is applied to the chain. It is installed in a strict position. according to the arrows, the ends of which are directed along the movement of the chain. The main pressure is applied to the leading edge, respecting the angle of inclination, which corresponds to the length of the chain pitch.
You need to try to have an equal number of movements for each tooth. The teeth are sharpened one at a time: one on the left side, the next on the right, and so on. For the convenience of performing the actions, the tire is clamped in a vice, and then processed through the prong on one side, then the same on the other.
During sharpening, the fixture must be held at a certain angle
The device and shape of the teeth
First of all, you need to understand the structure of the chain tooth, which must be sharpened. The tooth cuts wood like a plane. It has a complex configuration and an unusual cutting surface. two edges: one of them is lateral, and the other is upper, slightly beveled. The adjustable tooth stop adjusts the chip thickness. Of course, sharpening such teeth is much more difficult than, for example, a kitchen knife.
Chainsaw teeth have a more complex shape than other sharp objects to be sharpened
In this case, the correct angle of sharpening of the chainsaw chain should be set. It is clear that it is difficult to operate with one file, therefore there are various accessories that help to adhere to the exact parameters of sharpening. These kits are sold complete with chainsaws, as well as separately.
The diagram shows the angles of inclination that must be observed during sharpening
When sharpening, the location of the tool must be chosen correctly. The round file was not chosen in vain. due to the rounded shape of the inner contour of the tooth. The edge of the file should be 20% above the cutting surface of the file’s diameter, and the choice of diameter is influenced by the length of the chain pitch (typically 4 mm to 5.5 mm). The order of actions must be followed: first, the cutting teeth are processed, then the stop tooth.
What tools for sharpening are there
To start work, you need to stock up on tools that are divided into two types.
A set of tools required for sharpening saw teeth:
- Flat file, which is taught to use in labor lessons at school. Use it to grind down the depth gauge.
- A round file of a certain diameter, required for cutting a cutting tooth. An additional device is attached to it. a holder with fishing lines, which suggest how to properly hold the tool in relation to the chain. The holder is placed on the saw tooth, taking into account the guide lines, the file position is under the cutting surface.
- A template that serves for editing and observing parameters.
- The hook is required to remove sawdust from the chain.
Metal sharpening templates help you calculate the sharpening depth
When it’s time to sharpen the saw?
The periods between two sharpenings depend on the frequency of use of the tool. Some use it daily, others several times a year.
You can understand that the teeth are dull by some signs that come to light during operation:
- The chain stretches and sags, causing the saw blade to function inaccurately and slow down in the cut. Working with such a chain requires extra effort.
- The sawing process slows down, productivity drops, you have to spend twice as long on work.
- The type of sawdust changes: they become uneven, sharp, and smaller. Shavings from a sharpened saw looks different: the same pieces of an even rectangular shape.
If the saw loses accuracy and gets stuck in the cut, it’s time to start straightening the chain teeth.
Repair work should not be postponed for a long time. The sooner you sharpen, the less material you have to grind, and accordingly, the longer the service life. And you don’t have to work with a blunt instrument for a long time, increase its wear and tear and waste your own physical strength.

The fact is that the chain tooth of a chainsaw has a rather complex geometry. 2 cutting edges. top and side, of which the first is chamfered to the mowing line of movement at a certain angle, make this procedure not too easy. The tools we need are as follows: a round file, a flat file, a special template and a hook that will help us clean the sawdust off the saw. In some cases, you have to resort to a special machine for sharpening a chainsaw. Well, now let’s move on to the description of the traditional sharpening of a chainsaw with a file.
How to sharpen a chainsaw chain?
In this article, we will figure out how to sharpen a chainsaw chain. It must be said that sharpening chainsaw chains is perhaps a little more difficult than any other cutting tool. In addition, high-quality sharpening is possible only if you have special tools for sharpening. We will start with them, and then we will also consider automated chainsaw sharpening systems.
Chainsaw chain sharpener and how to sharpen the chain correctly
Crazystroitel.Ru will tell you how to sharpen a chainsaw chain yourself. What tools and devices to use.
If you want your chainsaw to serve for a long time and reliably, you need to constantly monitor that the chain is sharp.
You can sharpen the chains yourself. There are no norms for the timing of sharpening the chainsaw chain. This is influenced by how often and for how long you work with the device.
How to determine that the chainsaw chain is dull?
How to properly sharpen a chainsaw chain on a machine
If, during operation, the chain plowed sandy or even gravel soil, or did not sharpen for a very long time, it will be very difficult to sharpen it with a file, since this will require significant effort and time from you. In this case, a machine for sharpening chainsaws will help us. Such machines are divided into manual and electric, which are equipped with grinding wheels. The working part of the machine is somewhat reminiscent of a bow saw, except that instead of a blade, a long round file is inserted. The machine can not only sharpen the chain, but adjust the length of the teeth to a single size according to the control, as a rule, the smallest tooth. The mechanism for adjusting the grinding machines usually allows you to set the required parameters. The sharpening itself is performed with just two or three movements, after which you can proceed to the next tooth, while maintaining all the settings made for the control tooth. And one more thing: if possible, it is best to use an electric machine for sharpening chainsaws, as it is simple and very convenient to use. The electric machine has a setting system that allows you to set the chain at the desired angle, as well as bring the disc to the sharpened edge very accurately. There are also machines that automatically clamp the vice when the disc is lowered onto the chain. Well, for clarity, we have prepared for you, the sharpening of the chainsaw chain, which is considered in great detail. It’s always better to see once.

How to sharpen a chainsaw chain correctly. we will tell you the tool yourself!
A chainsaw without a normal chain belt is like a machine without a motor. This proven postulate will be confirmed by any tech-savvy person. The chain should always be well sharpened if you want to always use your chainsaw. Otherwise, she will not forgive you for miscalculations. This means that you will not see accuracy, efficiency and safety of work.
Any professional will confirm that the final result of such a laborious activity as working with a chainsaw will depend on sharpening the teeth of your tool, even more than on the motor itself. Experienced lumberjacks give the following good advice. sharpening is necessary as the sharpening sharpness deteriorates. If you have to put in a lot more effort than before, the saw starts sawing as it pleases and changes the angle, slowing down your work, in which case you have no choice. start sharpening.
Pay attention to the sharpness of the chain and escaping chips. If everything is in order with sharpness and sharpening, then the chips will be almost uniform, and the sawdust obtained at the output will be square in shape. If there is a need for sharpening, then this will be seen by the dust in the shavings and sawdust in the form of needles.
File and chainsaw. a successful tandem!
Remember to pay attention to each link in the chain. The rule should also be taken into account that the efficiency of the saw is determined by the difference in heights: we are talking about the distance between the cutting teeth and the limiter itself. Differences in height parameters allow the teeth to cut into the tree (usually a stop tooth in its characteristics should be about 0.7 mm below the cutting tooth).
How to sharpen a chainsaw chain. instructions for action
Do you want to use sawing equipment for a long time? Then take care of its timely prevention. It is necessary to sharpen the tool as needed.
The chain sharpening process is more difficult than sawing!
Don’t think that everything will turn out so easy the first time. But if you get the hang of it, you will achieve success. The cutting teeth must be sharpened first. For this, a special template is imposed. When sharpening along it, the arrows will indicate the direction of movement. Do not use physical force in such cases, but try to carry out uniform pressing at an angle directly to the saw bar with smooth and precise movements.
Experts remind that the angle of the slope itself in practice can be different and depends on the pitch of the chain. The main thing in such a jewelry and laborious work is not to rush and, as an option, remember how many movements you made. This practice of counting will allow you not to overdo it in one place and remember to perform the same amount of load in another.
Sharpened cutting teeth, it’s too early to rejoice. grinding of the stop tooth is ahead. A template is also used here (it is better to use a flat file here). As practice shows, if you sharpen without a template, then you can accidentally go beyond the mark, and then your chainsaw will "bite" into the tree and increase vibration when working with the material, which means you can simply forget about such an important characteristic as accuracy.
Things to consider:
If you are already ready to start sharpening, then it is better to do it right away, without postponing until later. And remember: the frequency of sharpening can vary significantly depending on the bark of the trees. If the bark from the logs is ripped off, then you can not sharpen the chain so often and, accordingly, cut longer. And don’t be afraid to use a chainsaw. If your trees and branches are small, you can always use different types of tree pruning tools. So good luck!
Sharpening the chain with a machine
Not all chains can be sharpened properly with a file. The most effective and efficient way is to use a special machine: manual or electric. This is the most accurate technology and can be done in two ways:
- Consistent sharpening with polarity reversal;
- Second cut method, when machining left-handed and then right-handed incisors without polarity reversal.
When performing work on the machine, several rules should be observed:
- The main reference point for the sharpening level is the bluest tooth;
- Grinding too deep will reduce the service life of the chainsaw and reduce the strength of the link;
- Experts recommend that after work, blow the chain with compressed air and put it in special oil for two hours.
This method has practically no drawbacks, except for significant time costs and great labor intensity.
How to sharpen a chainsaw chain
The level of performance of such a responsible and efficient device as a chainsaw is largely influenced by the care and timely maintenance of all equipment components, including the chain. A well-sharpened chain allows users to perform work with maximum comfort and safety. Qualified specialists note that knowing how to sharpen a chainsaw chain can significantly increase its service life, significantly increase the efficiency of the equipment and its productivity.
2 Sharpening chains from a chainsaw. when to grab the tool?
Even if you have never used a round tool, after buying a chainsaw, you will have to make friends with it. Her chains also tend to dull from time to time, but not throw them away! Much cheaper than buying a new chain will be to purchase (or dig out from the bottom of the toolbox) a round file for sharpening chains! By the way, if you have to buy a tool, then take an interest in the presence of a whole set, which is specially designed for sharpening chains.
The chainsaw tooth has a complex configuration. In fact, the chainsaw does not cut wood, but only slices very narrow chips, which is possible due to the two cutting edges. the side and the right. The upper edge is beveled at an angle to the mowing line of the chain movement, which allows it to plan. In addition to cutting elements, each tooth also has a stop-protrusion that regulates the saw to cut into the wood. With intensive work, chain sharpening may be required quite often, even several times a day. And if you accidentally hooked on the ground, then you can immediately go to this procedure. the teeth very quickly become dull from the small stones that are in the soil.
In any case, try to pay attention to the chainsaw as often as possible, then you will not have to linger for a long time at the chain, removing a decent layer of metal. The easiest way to understand the need for sharpening is by the operation of the chainsaw itself. a properly sharpened tool is literally pulled into the cut even with a slight pressure. And the chips will fly out large. If the teeth are dull, the effort will need to be applied much more, while the chips will be fine. But, in addition, fuel consumption will increase, wear of all parts of the tool will increase, and you yourself will get tired much faster from such a saw.
File the chain correctly. Circular file for sharpening chainsaw chains. learning to sharpen!
Any owner of the house keeps a file in a toolbox that can be used for sharpening. The main thing is to choose the right file sizes, which directly depend on the characteristics of the chain. For example, for a 1.3 mm chain, use a file with a 4 mm diameter file. A flat file is used to remove the "stops" from the teeth.
Cutting teeth are processed at a certain angle. You need to know that the tooth in the chain link is the manufacturer’s original notch indicating the recommended sharpening angle. In addition to the cutting tooth, there is a limiter in the chain link that regulates the maximum penetration of teeth into the wood. Restrictors are not sharpened as often, only when really necessary.
For the convenience and safety of work, a special auxiliary device is used. a clamp, with which the saw bar is fixed. In addition, one more equipment is used. a mold, which is equipped with convenient rollers for movement. It is important to choose the optimal sharpening angle and fix it with a piece. The template makes it easier to sharpen the chain and reduces the risk of incorrect movements.
Move the file in the same direction, not back and forth. Each tooth should have the same number of movements so that the surfaces are grinded as evenly as possible.
This method is one of the simplest and cheapest, but it takes consumers a lot of time and effort.
