Chainsaw chain sharpening: on the machine and manually
Who else but a gardener knows how important it is to have always working equipment at hand. Especially when it comes to a tool on which the speed of work and a high-quality final result depend.
In this article, we will tell you how important it is to carry out timely maintenance of consumables such as equipment such as a chainsaw. If you often use this device, then you need to be prepared for the fact that the chain headset will require regular sharpening. Because it is this process that allows you to achieve the best performance, without wasting power and excessive fuel consumption.
How to sharpen a chainsaw chain?
So that you can ensure the proper condition of your gasoline saw, it is enough to know when, how and with what tools you can sharpen, so that the sawing process is as efficient and safe as possible.
How to determine the state of a circuit?
When it is necessary to sharpen the chain, there are no exact guidelines. It depends on the intensity of use of the tool. However, it is also impossible to specially wait for the moment when the saw stops working efficiently. It is very important to pay attention to early signs of bluntness.
First of all, you need to make sure that the chain is securely fixed. If, when cutting wood, you notice that you are applying more force than before, then the tensioner is most likely unable to provide the correct operating tension. In this case, the chain is slightly stretched or sagged.
Pay attention to the quality of the chips. Ideally, it should be light, uniform and about the same size. With poor sharpening, the chips have a fine fraction of a dark color and with an abundance of visible impurities in the structure.
Sometimes you may notice that the chainsaw is tilted to the side. this is also a reason for sharpening.
How to sharpen a chainsaw chain correctly?
To learn how to sharpen correctly, it is enough to follow a few simple rules and have the necessary set of tools with you. Since the tooth of the chain is a complex geometric shape, this operation may seem quite complicated, but this is only at first glance.
Each tooth of the saw headset is represented by two cutting edges. lateral (vertical) and upper (horizontal), which has a bevel at a certain angle and is directed in the direction of the chain movement. Chip size and productivity depends on the depth gauge, which is located on each cutting tooth and serves to determine the maximum immersion of the cutting edges in the wood. They are sharpened only if necessary, as a rule, when you notice that the distance between the teeth and the separator has decreased significantly.
Tools for sharpening chains at home
There are two ways to sharpen a chainsaw chain. using a set of hand tools and a special mechanical or electric sharpening machine. Naturally, the first method is the most popular. However, professionals do not recommend using it very often, as this can lead to rapid wear and tear and disruption of the normal operation of equipment.
If you still prefer this method, then in your arsenal should be such devices:
- Round (cylindrical) file for sharpening cutting teeth.
- Depth gauge flat file.
- Template for ensuring rational sharpening parameters.
- Hook for easily removing sawdust, dust and other debris from the chain.
- Construction gloves to protect hands from unexpected cuts.
To fix the chain at home, you must use a round file of the appropriate diameter:
For chains with a groove width of 10.3 mm and a pitch of 3/8. a file with a diameter of 4 mm is suitable.
For chains with a groove width of 1.6 mm and a pitch of 3/8. file 5.2 mm
For chains with groove widths 1.3, 1.5 and 1.6 mm and chain pitch 0.325. files with diameters of 3.8 mm, 4.2 mm and 4.8 mm can be used.
If you are starting this process for the first time, then it will not be superfluous to watch an educational video, where experienced craftsmen share useful tips and gradually reveal all the secrets of successful sharpening.
How to sharpen a chainsaw chain with a file, and what rules must be strictly observed so as not to harm the tool
First of all, it is necessary to thoroughly clean the chain from oil, dirt and other debris. Inspect the blade carefully for damage, worn links and teeth. If flaws are found, its further use is dangerous for work. It is also worth paying attention to the length of the upper tip, it should be at least 1/4 inch. If the sharpening is shorter, then there is a high probability that the tooth will break during work.
Self Sharpening Chainsaw
Correct positioning of the device on the work plane is very important. It should be a flat and solid surface. For a high-quality performance of the operation, it is recommended to clamp the saw bar in a special vice. This will not only allow the blade to move freely, but also to adhere to the correct angle of inclination. The chain should be in a vise at an angle of 80 to 90 degrees to the surface. The sharpener, in turn, should move at an angle of 15. 35 degrees relative to the placed fixed chain.
The next step is to locate the leading torch. It is usually the shortest on the chain. If you are not observing it, then you can start sharpening from any blade. For convenience, mark with a marker the place where your work will begin.
Before you start sharpening the chain, place the template so that it fits into its slots. Then move the file along the cutting surface of the tooth and make several light movements with a protrusion of 3-4 cm, parallel to the lateral edges of the template. The direction of the file must be continuous and directed in one direction only. Moderate circular motions can be made to remove the resulting metal shavings. It is also important to keep the same number of strokes for each tooth. In the process of work, in no case should you rush. At this stage, it is very important to adhere to accuracy, care and accuracy.
Turn the tool over in a vise and move on to sharpen teeth that are in the opposite direction from those that you sharpened before.
If necessary, increase the distance of the depth gauge. Place the template and use a flat file to carefully grind off what falls under its slot.
Finally, lubricate the chain with special oil and check the tension.
Also on sale you can find such a set for sharpening, which consists of a flat file, a gauge template for sawing the limiter and a round file placed in a special metal plate (holder) with engraved lines.
When sharpening the chain with these tools, the cylindrical file with the plate should be positioned on the tooth in accordance with the indicated lines. The holder, in turn, rests on the top of the tooth and stop, and the file under the cutting edge.
To control the cutting depth limiter, a filing gauge is used, which contains special shaped slots. It is fixed on the cutting tooth and, using a flat file, that part of the stop that protrudes from under the surface of the caliber is grinded.
How to sharpen a chainsaw chain on a machine?
If you do not want to sharpen the chain by hand, you can use a manual or electric sharpener. The most popular, of course, is network technology.
The electric machine has a solid base, a movable upper part and fixing components, consisting of a fixing screw, a set screw, and a set wedge with a chain holder. The base of the case is represented by one start button, a depth stop and a scale for setting the angle and sharpening level. An abrasive grinding wheel is used as a working component. For the most convenient use, there is a handle and special protection elements.
The main advantage of the electric machine is that it has a certain system of settings, making it possible to place the cutting blade at the correct angle and bring the disc to the sharpened edge with maximum accuracy. Each tooth is sharpened separately, the user only moves the chain along the holder. There are also models that automatically clamp the vice when lowering the disc chain onto the tooth.
The procedure for sharpening is more than simple:
- Place the saw head in the machine, with the links towards the blade.
- Find the shortest tooth on the chain. this will be the main reference point for determining the level of sharpening.
- Set the required machine settings. Lower the circle to the shortest tooth, then without changing the settings, go to the next.
- At the end of sharpening, blow out the headset and treat it with oil.
To ensure that the sharpener will serve you as long as possible, after each use, blow the mechanism with clean compressed air and lubricate with machine oil.
As for hand-held machines, they are shaped like a ray saw, but instead of a saw blade, a cylindrical file is used. The use of such a device has several advantages. Firstly, all the working edges of the chain set are sharpened in exactly the same way. Secondly, the file moves at a given angle and the likelihood of even the smallest deviation is completely excluded. The required sharpening parameters are set by the user independently before starting work.
How to Sharpen a Chainsaw with Elegant Efficiency [smoother & straighter cuts]
You can buy a machine for sharpening chainsaw chains on our website, where a large selection of equipment of this type is presented, each model is described in detail, all technical characteristics are given.
After you have sharpened, do not forget to make sure that the chain tension is correct. A saw head that sags may come off the tire or get stuck in the wood during operation. Padding is also bad. excessive load on the engine is created.
Therefore, it is very important to control the chain tension and, if necessary, make adjustments before each start of work with the power off. The process of tensioning the chain is not difficult, all that needs to be done is to follow the correct sequence of actions, which is prescribed in the instructions for each tool.
First, loosen the fasteners on the chain saw cover that holds the saw headset. Then insert the screwdriver key into the corresponding groove, and carefully rotate, while pulling the chain. A couple of turns is enough. To check the tension, pull the chain by hand at the bottom of the bar in the direction of travel. If it does not move, then the fastener is too tight and needs to be slightly loosened. Ideally, the sliding of the blade should be smooth without snags and unnecessary sagging.
Important! In no case should the chain be tightened or replaced while hot, as after cooling it tends to contract again. Doing so can lead to irreversible deformation of the guide bar and damage to the motor. Wait for the moment of complete cooling, and only then proceed with the adjustment.
How to sharpen a chainsaw chain. sharpening principles using files, templates or machine tools
If you purchased a chainsaw, be prepared to sharpen it regularly. This is a prerequisite for the effective operation of the tool, without which performance suffers, fuel consumption increases, engine load and wear of all tool parts increase. In fact, sharpening your saw chain is more important than engine horsepower for quality performance. And if a low-power tool is quite suitable for small sawmill needs, then do not even try to work with a blunt saw. nothing good will come of it.!
The chainsaw must always be sharp.
How to sharpen a chainsaw chain by hand
The best tool for sharpening chainsaw chains is a file. Since the inner surface of the tooth is close to a circle in shape, a round file is used for this purpose. In order to grind off the depth gauge, you need another file. a flat one. It is not worth picking up the necessary tool separately. ready-made kits are available for sale, suitable for chains with various production characteristics. One of the most common sets consists of a round file for cutting blades, a flat file for a depth gauge and a template to ensure correct sharpening parameters.
Chain sharpening kit: round file, flat file and custom template
For sharpening the cutting teeth, the template is applied so that they fall into its slots. Then it remains only to bring the round file under the cutting edge and make several movements parallel to the lateral edges of the template. Movements need to be made only in one direction, and the same amount for each tooth, so that the grinding of all chain elements is uniform.
The movement of the file must be parallel to the edges of the template
If it is necessary to increase the distance of the depth gauge, a template is also superimposed on it. Anything that gets into the slot must be filed down with a flat file.
Sew the part of the stopper that falls into the slot of the template
Another popular chainsaw sharpening kit consists of a round file inserted into a holder, a flat file and a gauge for sharpening the stop. The holder is a metal plate engraved with straight lines that help determine the correct sharpening angles of chainsaws.
Popular set for sharpening saws: flat file, gauge and round file in holder
When sharpening the saw, the file with the holder is positioned on the tooth according to the reference lines. In this case, the insert rests on the stop and the upper part of the tooth, and the file is under the cutting edge.
Sharpening chains with a file in the holder can be done independently and, moreover, quickly enough
How to sharpen your own chainsaw teeth for less than $40
To control the height of the depth gauge, this set uses a gauge. a small plate with a slot. They put it on the cutting tooth and grind off that part of the limiter that looks out from under the surface of the caliber.
Features of the structure of the saw chain teeth
Chainsaw teeth are complex and can be difficult to sharpen. Each tooth has two cutting edges. a vertical side and a horizontal top, beveled at an angle. Each cutting link is also equipped with a depth stop, which determines the thickness of the chip and the productivity of the work. The height distance between the leading edge of the back of a tooth and the top surface of the depth gauge is called the depth gauge distance. On average, it is 0.5-0.8 mm. Since this distance decreases after each next sharpening of the cutting edges, the depth gauge must also be sharpened regularly. This should be done approximately every 5-10 sharpenings.

The structure of the cutting link of the chainsaw chain
Before starting work with a chainsaw, it is imperative to check the sharpness of the chain, because the earlier the dull blades are sharpened, the less metal will have to be removed. The service life of the saw will be increased accordingly. Of course, it is impossible to sharpen the chain ad infinitum. there is a limit that is knocked out on the teeth in the form of dashes. You cannot grind metal outside these lines. the chain will not work normally. As a rule, this happens after 10-15 sharpenings.
When it’s time to sharpen your chainsaw?
By the way, you can’t wait until the tool stops sawing and then just start sharpening. There are signs by which you can determine in advance that it is time to take out the file (this is the main tool that is used to care for the teeth of chainsaws).
A sharpened chain tooth is an ideal to strive for
Dull saw tooth in need of sharpening
So, if you find yourself using more force than usual when cutting wood, then the saw is most likely dull. Chip quality is also an indicator of poor tooth condition. Ideally, it should be large, about the same size. Dark shavings mixed with dust and fine chips indicate that the chain needs sharpening. On average, household chainsaw chains are sharpened 1-2 times a month. The tools of professional lumberjacks involved in felling should be sharpened more often. about once a day.
How to sharpen a chainsaw chain on machine tools
Sometimes, when the chainsaw chain is very worn out and it is difficult to sharpen it manually, special machines can solve the problem. manual or automatic. Such accessories are used in service centers or tool repair shops, but you can also purchase it for personal use. Then the question of where to sharpen the chainsaw chain will lose relevance for you. you can do this work (moreover, in large volumes) at home.
[include title = “YAN. in text”]
Manual machines are stationary or mobile. The latter are lightweight and, when sharpening the chain, are put directly on the bar. These machines allow you to fix file movements at a certain angle and eliminate the likelihood of even the smallest deviation from the set course.
A mobile hand-held machine will allow you to sharpen the saw directly on site
complex devices are electrical machines that require permanent installation. In this case, sharpening is done using special discs. Any automatic chain sharpening machine is characterized by an efficient adjustment system that sets the chain at the right angle. This brings the disc to the tooth as needed. There are machines in which, when the disc is lowered onto the tooth, the vice is automatically clamped.
An automatic chain sharpener is an expensive option, but very effective.
However, automatic chain sharpening machines are rarely used even by professionals; round and flat files are most often used. You can see how the standard sharpening of the chainsaw chain takes place in a short video.
Do-it-yourself chainsaw sharpening
The tooth of the chain planes the wood like a plane, and the thickness of the shavings is adjusted by the height of the stopper.
The heavy work of the saw leads to a quick dullness of the chain. Sharpening angle for the link which you can also watch the video of sharpening the chainsaw chain. Several sharpenings may be required within 1 day. The problem is aggravated by the fact that the tooth rapidly becomes blunt 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 small, and the saw stops going deep into the tree.
The earlier the blunt teeth are sharpened, the less material needs to be removed when sharpening, as a result, the service life of the saw chain is longer. How to sharpen a chainsaw chain sharpen a chainsaw chain sharpen a chain to. Chainsaw Chain Sharpening | video in Zaporozhye. Finding the moment when sharpening is already required is quite easy. The main 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 an increased feed force, then the teeth are dull. A 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. this results in strong tension in the body, high repetitive stress, poor cutting results. In addition, this means a decrease in productivity, high fuel consumption and overestimated wear of all chainsaw units.
How to understand that the chain is dull
The long service life of any chainsaw depends on proper care and use, including the chain headset. The good performance of the latter affects the performance of the device and performance parameters. Failure to sharpen in time can cause some problems in the operation of the saw itself. Most often these are:
- curves cuts;
- large loads on the saw, as a result of which the wear of the device parts increases, and hence a decrease in the service life of the entire device;
- increased fuel consumption.
If, as a result of the sawing, small dust-like shavings are formed, and the saw itself sinks into the saw with great effort, then the target is dull.
There are other signs of chain bluntness:
- the speed of the tool has decreased;
- rough and sharp sawdust is formed;
- it is necessary to make great efforts to cut wood;
- the chain has stretched or began to sag.
Preventing the chain from dulling quickly
It is possible to extend the life of the chain without periodic sharpening if you pay special attention to careful maintenance of the headset. In particular, it requires:
- Use of specialized oil, which must be added when refueling the chainsaw. To select the required concentration, it is recommended to read the instructions for the oil itself.
- All unused volume must be disposed of.
- During operation, it is recommended to periodically check the dimensions of the gap between the stop and the edge of the tooth. Ideally, it should be 0.7 mm.
- In order to minimize the risk of tooth curvature and one-sided abrasion, the tire can be periodically rearranged 180 degrees.
- The drive sprocket must be lubricated systematically. This must be done before each use of the saw. You can choose the oil that is diluted with gasoline and added to the fuel tank. But the M8 brand has the best performance.
- Observe the tension indicators. The chain must be aligned with the grooves of the bar.
How to sharpen a chainsaw correctly
Timely and competent do-it-yourself sharpening of chains for a chainsaw will allow not only to extend the use of the device, but also to save effort and time for processing wood. Signs of a sharp chain are the formation of sawdust of the same size and regular geometric shape. To ensure the desired level of sharpness of the teeth, any device for sharpening chainsaws, for example, any sharpening tool, will do. These are a file, a grinder and a machine.
Sharpening a saw chain from a chainsaw on a machine purchased from OBI, my detailed instructions
The credit accessory is very comfortable.
When sharpening all teeth, do the same number of strokes with the ratfil at the same pressure. This will result in a uniform tooth length. All cutting teeth must be of the same length. Different tooth lengths are a prerequisite for uneven chain running and cracking. In this video I will show you how to sharpen a chainsaw chain at home. Sharpening the chain on a chainsaw is very convenient and just with the help of a file and a vice, you can easily sharpen the chain on. 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. Sharpening the chain on the bg60016 machine. Chainsaw equipment / chain sharpening correctly. 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 ratfil.
The principle of using another set for sharpening chainsaw chains does not differ from the first, although its design is different.
A round ratfil is also used to sharpen the cutting tooth, and a thin one is used to sharpen the depth gauge. The special template ensures the sharpening characteristics of 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 ratfil placed on the template and brought under the cutting edge rests on the guide rollers. The direction of movement of the ratfil should be parallel to the lateral edges of the template.
When grinding the stopper, the template is applied so that the stopper falls into the slot, near which it is written SOFT (for soft wood) or HARD (for hard). As in the case of the first device, sewing is done with smooth, even movements of a flat ratfil away from you.
Signs of wear on the chainsaw cutting edge and the required sharpening frequency
The operation of such household equipment requires mandatory compliance with certain requirements. An unsafe event such as sharpening chainsaw chains is the right thing to entrust to a professional owner.
First of all, it should be remembered that the processing of the saw blade should be carried out in accordance with the peculiarities of the shape of its tooth. Thus, in modern chain saws, teeth are positioned in two ways: from the side or from the top.
It is important to take into account the angle of sharpening of the chain, since the cutting elements are to a certain extent, which is almost the main criterion in the implementation of measures for sharpening the cutting edge. The sharpening angle is usually indicated on the packaging.
It is important to understand that the denser the cutting material, the deeper the sharpening angle. As a rule, craftsmen, who have been seen often and many times, have several chains with different angles of sharpening teeth. For example, for longitudinal sawing of a tree, its value is in the range of 10-12 degrees
The main signs of the need to perform the procedure associated with sharpening the chain are as follows:
- in the process of work, the tool moves randomly from side to side, regardless of the angle of inclination;
- the speed and efficiency of work falls;
- wood shavings from sawing wood differ from the standard appearance and texture;
- cutting blade not stretched enough.
As for the frequency of the grinding procedure, there can be no specific time, the main criterion here is the frequency of operation of the device and its functional characteristics.
The tool for sharpening a chainsaw may be different, due to the variety of models of these household appliances, as well as different workflow technologies that provide different procedures.
The main tools used to cut a gasoline saw blade are:
- File suitable for diameter (its shape can be round or flat and combined patterns are acceptable);
- Machine type;
- Automatic machine working with electricity;
- Standard Bulgarian.
The saw chain is a metal base with series-connected links that have teeth characterized by cutting properties. You can improve them if you sharpen the chainsaw chain at home, but you must follow the rules and use a tool specially designed for this. The latter can be homemade or factory made.
How to sharpen with a grinder grinder
When sharpening a chainsaw chain with a grinder, it is necessary to constantly monitor the level of chain sharpness, treat the drive sprocket with machine oil. At the same time, this method has one significant advantage. it is not necessary to remove the chain set from the saw, you can visually select the sharpening angle.
Although many owners of chainsaws and chainsaws believe that this tool can damage the cutting teeth of the chain, if the work is done by an experienced specialist, then the risk is minimal.
Only a special disc is suitable for working with metal. Its diameter must be at least 2.5 mm. In this case, it is recommended to select an already used disc with rounded edges.
Before you start sharpening, you need to insert a wedge of wood between the chain and the bottom of the bar to prevent the headset from moving.
Using the grinder
As a rule, it will be difficult for an inexperienced person to handle a grinder in such a matter. So there is a risk of ruining the instrument. This is a very difficult method, and it is better to refuse it by a person who does not know how to handle this equipment.
How to get rid of a toothache, read the article.
It is necessary to take a disc for metal with a thickness of 2.5 mm and put it on the grinder. There is absolutely no need to remove the chain from the chainsaw. The sharpening angle is chosen exclusively by eye. Experts recommend only installing a wooden wedge between the chain and the underside of the bar.
The positive aspects of this method are that you have to spend a little time, and the service life of the equipment can be extended even at home.
The disadvantages when working with a grinder include the need to adhere to safety measures. It is imperative to have a protective face mask and gloves for hands.
Chainsaw chain sharpening
It is better to entrust such a difficult matter as sharpening the cutters of such a device to a specialist who at least has an idea of the tools with which to work in the process. It is not difficult to determine the time when to take emergency sharpening measures. As a rule, the chainsaw itself manifests itself from the bad side and this happens at the moment:
- reducing the speed of rotation of the saw;
- when the instrument starts twitching in different directions;
- characteristic changes in the quality of the shavings, it seems to turn not into sawdust, but into needles.
In addition, you can understand that it is time to sharpen the teeth of the tool by dust in the chips. It simply should not be noticeable during the workflow.
Every owner wants to try to do it on his own, relying on the good result of his work. over, there are many ways and tools to help you do this. For this you will need:
- files of various sizes and shapes;
- sharpening kit;
- quality chain sharpening machines.
Sharpening of the tool can be carried out in time depending on the intensity of use of the chainsaw. Of course, if there is no special need to turn it on, then the teeth will remain sharp. Of course, it is more difficult for lumberjacks, because they practically do not part with this tool, and summer residents constantly grind down the chain during the pruning season.
How to sharpen a chainsaw chain yourself
In order to ensure the quality of work with the chainsaw and increase its service life, it is necessary to regularly sharpen the tool chain. It is important to do this in a timely manner, as you can violate safety rules when working with a chainsaw and injure yourself. The final result of the laborious process depends on how to sharpen the chain. According to experts, the sharpening of the teeth should be done as their sharpness deteriorates.
Helpful Tips for Maintaining the Chain
Only with proper maintenance of the tool, you can not worry about its service life. You can take the saw to the workshop in a timely manner as a preventive measure, or you can just talk with specialists in order to understand how to sharpen its chain yourself.
Here are some helpful tips for caring for this tool:
- it is necessary to control the sharpness of the chain so that the teeth do not grind off completely;
- periodically, for example, before starting work, you need to lubricate the drive sprocket with machine oil;
- the tire should be rearranged from time to time so that it does not wear off on one side;
- it is necessary to regularly check the condition of the fuel, as well as the air filter, which are in the engine, in the tool for water and dirt;
- before starting to work with the tool, you need to check the tightening of the nuts and screws so as not to injure.
Not many people use a chainsaw regularly. It is usually only needed during the pruning season. It also happens that the tool is gathering dust for a long time, no one uses it. To protect it from breakdown, you need to pour the fuel mixture into the engine, start it so that it can stand for a while. It is better to inspect the tool in a timely manner than to pay for the repair of the carburetor and engine later.
The video will clearly demonstrate the process of sharpening the tool chain.
Using a sharpening machine
Such a machine may be needed when the situation is completely neglected and the files can no longer cope with their work. These devices are of two types: manual and electrical.
The principle of operation of the manual machine depends on the bow saw, which must be installed on top. With its help, the teeth of the tool will be sharpened. Thus, each link can be adjusted to the same size.
You should not change the settings of the machine during operation, so as not to knock down the entire mechanism. All links must work with the same precision, thanks to the same type of movement of the machine. It is also worth remembering about the limiter, the work on which begins only at the end of the sharpening of the teeth. Change the round file to a flat file. On an electric machine, this process is also reduced to automation.
Find out how to sharpen a ceramic knife here.
It would seem to be a pleasure to work with an automatic machine. You do not need to set the settings yourself and monitor the chain clamping. True, there are some nuances here:
- before installing the chain in the machine, you need to loosen the screw, and direct the teeth towards the grindstone;
- the sharpening angle must be sharp;
- in order not to be confused with the polarity, if the machine does not change it on its own, you must initially sharpen the even teeth, and then the odd ones, counting from the control one;
- the chain should be carefully placed so as not to sharpen very deeply, as this may affect the performance of the chainsaw in the future;
- at the end of work, it is necessary to process the chain: clean it of dust and debris and leave it in engine oil for a couple of hours.
Using a hand-held machine, you also need to clean the chain from metal dust at the end of the work. Machine oil has always been lubricated with such parts for better gliding of the tool on wood.
Sharpening with a special set
Typically, such a set consists of two files, a round and a flat file, a holder, hooks for easy cleaning of the teeth, a template, gauges and several handles that can be put on files.
The holder contributes to the successful fixing of the position of the file in the working process in relation to the chain, controlling the protrusion in the chainsaw above the edge of the tooth and responding to all possible tilt angles.
The gauge allows you to adjust the exact depth of the tooth edge. It is a metal plate on which there is a limiter, which is required specifically before sharpening.
The template performs useful functions of both the gauge and the holder, as it is responsible for sharpening the cutting teeth and the stop.
When working with a sharpening kit, you must adhere to a certain sequence of actions:
- Install a tight clip for the chain, which will slow down its sliding.
- Secure the template as much as possible. It is important that the arrows embossed on the template point exactly to the nose of the tire.
- Make a mark on the first tooth, from which sharpening will begin, so as not to get confused.
- Carry out work with sharpeners from yourself.
- Change a round file to a flat file and take a control tooth.
If the teeth of the chain are not dull, then you can get by with a sharpening kit. For more serious work with the tool, you will have to use the machine.
When working with round and flat files, be aware of the distance between the teeth, which should be adhered to. It is unlikely that everything will work out the first time with an inexperienced specialist. This is a very laborious process that requires close attention.
First you need to sharpen the cutting teeth, to which it is better to attach a template. Without applying excessive force, you need to carry out equivalent clicks at an angle with smooth movements, gradually approaching the saw bar. The angle of inclination can be very different, depending on the pitch of the chain.
After the sharpening of the teeth has been finished, you should start grinding the stop tooth. In this case, it is also better to use a template so as not to accidentally protrude beyond the mark. When working with the limiter, a flat file is useful.

I bought a device. an ordinary round file, plus something like a template to control the angle. All this cost 250-300 rubles. I sharpened for a long time, probably an hour, it seemed like it got better, but still I can’t compare it with a new one. My hands are probably crooked. Then I got tired of it, and bought a special electric sharpener for 900 rubles. Although it is China, it sharpens very quickly and well. about 5 minutes per chain. So advice. do not suffer, but immediately take an electric sharpener
Chainsaw chain sharpening is not so difficult and anyone with any experience in sharpening any cutting tool can handle it. But still, without special devices, you cannot cope with it.
The chainsaw tooth has a complex geometric shape, it consists of two edges: side and beveled at a certain angle. the top. All this complicates the operation a little.
In this article we will give several correct ways to sharpen a chainsaw chain with your own hands.
Possible ways and methods of sharpening the chain
We sharpen with a grinder
Professionals consider this work to be primitive. There is a risk of tire damage, and not only.
Process (seemingly easy, but really difficult)
- The chain also stays on the bus;
- We attach a cutting disc for metal with a thickness of 1.5-2 mm to the grinder. It is advisable to take not a new one, that is, with an underworked edge;
- We put an obstacle in front of the chain and the tire (the chip will come off);
- We sharpen at the desired angle;
- Upon completion of work, the chain must be properly tightened.
With a professional approach and a “full hand”, the number of sharpenings in this case can be more than 7.
“For a beginner, it is better not to“ experiment ”with a saw, a chain, etc. with your body parts! “
Advantages of the method: Fast, cheap and does not take up energy;
Disadvantages: Requires special skills, a steady hand and the ability to comply with safety techniques.
Chainsaw teeth have a specific geometry. You need to understand and know what part of them should be sharpened. In general, the “logic” of cutting wood resembles a plane.
The cutting surface has two edges. One is lateral, the other is slightly beveled. The cutting depth limiter adjusts the thickness of the chips. Let’s take a closer look. The elements of the cutting-working link are arranged as follows:
- Base with axle holes;
- Tooth scapula;
- Cutting depth limiter;
- End face of the blade (placement. vertical);
- Upper edge of the blade (placement. horizontal);
Sharpened edge Dull After touching the ground
After sharpening, the height of the stop and the angle of the sharpened working edges should not differ greatly from the parameters specified by the manufacturer. This is an important condition and it needs an “eye and eye” behind it. Otherwise, the saw will not work as expected.
Do not over-grind or change the location of the links. The normal operation of the instrument depends on the identity of their location. Otherwise, increased stress on the chassis, tire and engine is likely. The cut can be crooked. There is also a small chance of breaking the circuit.
We work with a file
The best solution is simple gadgets for sharpening work. This set includes a round and flat file, special holders, a gauge template, a hook for removing chips, etc. Structurally, “adaptations” may differ, but the functionality has a common logic.
The diameter of a round file is directly related to the size of the chain:
- – Chains with ø 1.3. require a file of ø 4 mm (used much more often);
- – Chains with ø 1.6. require a file ø 5.2 mm;
- – To sharpen the depth gauge, use a flat file.
- Having previously “turned on” the chain brake, firmly grip the tire of the chainsaw in a vice (a firmly clamped saw is the key to successful sharpening)
- Set the template so that the arrow points towards the nose of the tire. Be sure to mark (with chalk) the tooth from which you started sharpening, otherwise you can go along the second circle;
- Sharpen in the direction of the arrows. Remember, there is a special factory cut on each tooth in the chain. It indicates the maximum sharpening angle.
- In addition to the cutting tooth, there are stops on each link. They are sharpened as needed. This is necessary when, as a result of sharpening, the height of the tooth decreases, and problems arise in the operation of the chainsaw. As a rule, the limiter is sharpened after 2-3 sharpening of the teeth;
“If you don’t have the skills to sharpen, it’s better to start with inexpensive chains.”.
- The file should not go beyond the upper part of the cutting edge by more than 1/5 of the working part of the file. The pressure is carried out with the same effort;
- The movement of the grinding tool is performed in one direction “away from you”, and the number of movements for each tooth must be equal;
- To sharpen a vertical plane, the position of the file must be at right angles;
- For sharpening the horizontal plane, file position, at an angle of 20-30 °
- If there are teeth of different heights, the reference is the smallest.
Advantages: Ability to “charge the saw” in the field. At the same time it’s cheap.
We sharpen the chainsaw chain with our own hands. All possible and available ways
“The lumberjack working with a blunt ax was advised:. Sharpen the ax.
He replied:. There is no time. It is necessary to cut down the forest. “
Greetings to all readers!
Today I decided to tell you about the tool, without which, as it seems to me, today it is simply impossible. A good tool should work well, and this largely depends on its owner.
Cleaning the autumn garden, preparing firewood for winter, building a bathhouse, repairing a wooden fence will require not only time and desire, but also the readiness of the “cutting” tool. If it is a chainsaw, then it must be properly sharpened.
Of course, there are paid specialists, and you, for example, have extra money. But we know that such a procedure is performed periodically and therefore a natural question arises: how to sharpen a chainsaw chain at home? I’ll tell you about that. Go!
In this article, you will learn:
First about the horror stories
If you cut with a blunt chainsaw, you will get three negative factors:
- Reduce the efficiency of your process. For example, instead of two cubes, file one (at the same time);
- Expose the mechanism to intense wear, with the risk of destroying the drive sprocket and tire;
- Get increased fuel consumption;
There is also a fourth, perhaps not so significant factor. “torn” cut of the saw cut.
And of course, you will get tired more, you will (possibly) be angry with yourself, like “why should I be a fool, do not sharpen in advance, now suffer.”
Here is a test question for you (photo on the right). Guess what kind of shavings “came out” from under the sharp and dull chain? (the answer will be below).
Electric sharpening machines
They are equipped with special adjustment functions to help you position the chain at a certain angle. At the same time, it is possible to accurately and accurately bring the disc to the chain teeth. There are machines equipped with automatic vices. They are switched on when the disc approaches the edge to be sharpened. Convenience and functionality are of course high. You can find models at “lifting” prices.
