Proper sharpening of a Stihl chainsaw chain. Sharpening a saw chain using a machine. As a conclusion

Chainsaws are actively used by many summer residents and owners of country houses. This tool is indispensable for collecting firewood and other garden work. Its effective use is possible provided that the saw chain always remains sharp. Let's see how you can sharpen it yourself if necessary.

When sharpening is needed - signs of a dull saw

A sharp chainsaw chain is a prerequisite for the safe and productive use of the tool we are interested in. A special machine allows you to sharpen it. But not every home craftsman has it. Therefore, most summer residents use a file for sharpening. Such work is quite complex, which is due to the special geometry of the saw teeth, which have two cutting edges - the top and the side. Moreover, the first of them has a clearly adjusted bevel

With active use of the tool, the chain very quickly loses its sharpness. This significantly complicates the process of using the saw and leads to unpleasant results:

the tire and drive sprocket of the cutting device may well collapse, which will require their replacement or expensive repairs;
a chainsaw consumes a lot of fuel;
the tool is subjected to high cyclic load;
cutting wood becomes of poor quality and requires additional effort;
The useful life of the device is reduced due to wear and tear of its mechanisms and components.

Of course, this cannot be tolerated. The sooner we put a dull chain in order, the faster and better we can complete all planned work using a saw. Sharpening of the described tool should be carried out without delay in the following cases:

1. If we feel that the saw is starting to cut the wood poorly (it takes serious effort to cut the latter). A normally sharpened device is pulled into the cut without strong pressure.
2. When the chips flying out from under the saw have changed color. In particular, it became darker.
3. If instead of thick and large chips, only thin and small chips start to come out of the cut.

In addition, the dullness of the tool is easy to see with the naked eye. And craftsmen who use the saw quite often, even without additional inspection, perfectly feel when it needs regular sharpening. As soon as we notice that work productivity drops and the use of a tool becomes difficult, this is a clear sign of its dullness.

Tooth characteristics – what do you need to know?

The cutting link of the gasoline engine device we are considering structurally includes: a base, a blade, and a special limiter.

There is a first blade (end blade) on the blade of the tooth. It is located vertically. Above it (horizontally) is another blade. In order for the saw to function truly effectively, we need to give both cutting elements angles of a certain size. Let's briefly describe them:

1. Angle (back) of the upper blade. It is formed by the back of the tooth. It allows the chainsaw to cut into the material being processed.
2. End blade angle. Formed by a scapula narrowed backwards. It makes it possible to trim chips on the sides.
3. Front corner. It is formed by the sliding surface of the blade and its edge.

The sharpening angle can be selected individually, focusing on what kind of work you plan to perform with the saw. There are two nuances to consider here. The first is that reducing the sharpening angle when processing hard wood reduces tool vibration. This ensures smooth running of the latter. Secondly, when cutting soft trees, increasing the sharpening angle increases the performance of the saw.

There is a depth limiter on each individual link. It is located in front of the scapula of the tooth. The size of the limiter is the distance between its edge and the cutting back of the tooth. It determines the performance of the cutting process, as it sets the depth of immersion of the saw into the wood. In most cases, the limiter distance is taken within 0.5–0.8 mm.

A set of files - we will make any saw sharp

The easiest way to sharpen the chain of a modern chainsaw at home is with a special set of tools. It is recommended to purchase a standard set of devices for performing such work, which includes:

1. Round file. With its help we will sharpen the cutting tooth of the saw.
2. Flat file. It is used to grind down the depth stop.
3. Special template. It is necessary to check turning and dressing parameters.
4. A special hook that allows you to clean sawdust from the chainsaw.

The round file is equipped with a holder on which round marking lines are applied. They make it possible to position the sharpening tool as correctly as possible in relation to the chain being processed. The holder is mounted along the indicated lines on the saw tooth. In this case, the file itself is located under the cutting edge. Important point! We select files taking into account the type of chain of our saw. There are many options. Flat files can have a width from 4 to 12 mm. And the diameter of round devices varies from 3 to 6 mm.

When sharpening, 1/5 of the file must protrude above the cutting edge. This is a must. During the work process, move the file strictly in one direction, and not back and forth. In addition, we slightly sharpen the limiter every few sharpenings. In general, the scheme for restoring the sharpness of chainsaw teeth looks quite simple:

1. Clamp the saw between your knees. We install the chain brake.
2. We display the template included in the kit. Its guide arrows should point towards the front of the tire.
3. Mark the first tooth to be sharpened with chalk.
4. Move (away from us) the round file, sharpening.
5. Take a flat sharpening tool. We use it to remove the control tooth. In this case, you can move the file in any direction.
6. We process the remaining teeth in the same way.

As you can see, the process is simple. Although at first it causes difficulties for many home craftsmen. It's OK. Mastery comes with experience. We make smooth, unhurried and measured movements. From time to time we turn the file used for sharpening chainsaw chains to prevent wear on one side.

Nuance. When sharpening, count the number of file movements on individual teeth. It must be the same for all elements. Thanks to this, we get a chain with equal tooth lengths. If their sizes are different, the chainsaw will move unevenly, which is guaranteed to lead to the appearance of chips and cracks in it.

Sharpening machine - if the file does not cope

Some chains cannot be sharpened with a file. Similar situations occur when the saw was not looked after, the sharpness of its teeth was not restored for a long time, or it was used extremely carelessly. In such cases, there is only one way out - the use of special machines. They are manual and electric. The machines have a working part that is visually similar to a bow saw, in which the function of the sharpening surface is performed by a long round file.

Electrical units have become widespread. They can be adjusted to any sharpening angle. Many of them perform vice clamping and other operations automatically. The main advantage of such devices is the high accuracy of the work. The algorithm for sharpening chains on them is as follows:

1. Set up the chain clamp. The operation is performed using a screw or other device on the unit.
2. Place the chain in the groove of the machine. The saw blades should point towards the file.
3. Set the required processing angle.
4. Select the polarity, focusing on the option of sharpening the cutter (right- or left-handed).
5. Turn on the machine. We sharpen every second tooth (if we don’t want to constantly change the polarity) or everything in a row (then after each tooth we will have to set a new polarity).

After sharpening, experts advise blowing the chain with a jet of compressed air, and then placing it in machine oil for 20–30 minutes.

To sharpen a chain, you probably don’t need to put in a lot of effort, since it’s not very difficult. In this article, we’ll look at how to properly sharpen a chain on a chainsaw, and look at all the smallest details.

First you need to find out the reasons why the chain becomes dull.

So, let's go!

The chainsaw tooth you want to sharpen has a heavy geometry.

It has two cutting edges - one on the side, one on top - one of them is beveled at an angle that determines how the chain should move, and it makes the operation a little tricky.

A chainsaw with high power cuts down the entire tree, and with the help of a limiter you can determine how thick the chips will be, small or large.

Why does the chain get dull?

If you work a lot with a chainsaw, it will very soon become dull. And you will need to sharpen it a couple of times a day.
Also, the main problem why the chain becomes dull is the soil. If you accidentally snag the soil, you can immediately go sharpen it, since it will no longer cut as it should, the chainsaw no longer cuts into the tree as well, and you will immediately see that the chips become much smaller than before.

In order for the service life to become longer, you need to sharpen it as soon as possible, as soon as you see that the saw is no longer sawing as actively, go and sharpen the teeth, because if you tighten it, you will need to remove more material from it.

The main check when it comes to sharpening the teeth is to give the feed a little more.

If the chain is sharpened, it crashes into the tree very quickly. Well, when you constantly increase your feed to the maximum, you definitely need to sharpen.

A chain that has already become dull is very easy to calculate, as already written above - these are small chips.

Reasons why you should not cut with a chainsaw that has dull teeth:

Your body is very tense due to the high vibration going on
Immediately visible deterioration in cutting
Of course, productivity decreases
Fuel and oil consumption increases greatly
There is also a lot of wear and tear on all parts of the chainsaw, which will soon require repairs.

How should you sharpen a saw, what tools should you use to sharpen it, and at what angle is it correct?

Let's start one by one, the sharpening angle of the chain is measured depending on your case for use, let's say, the higher you take the angle, the stronger and more productive it will cut soft wood.

The sharpening angle for the link that cuts affects the chain, on average it should be from 50° to 60°

When we reduce the angle, then the saw will enter hard trees very smoothly, and accordingly, the vibration is much reduced and does not radiate into your body.

Now we take a protractor and measure, it is strictly forbidden to sharpen the chain more than 35 degrees or less than 25 degrees (with the exception of a chain for longitudinal cutting, which has an angle of 10°)

Now you need to find out what tools you need to sharpen your chains. Since the contour of the tooth itself is similar in shape. You need to use a file (round) of small diameter.

Sharpening needs to be done very precisely, you should hold the file clearly, without changing the angle, its upper edge of the file, it should protrude at the upper edge of the tooth, approximately 1/5 of the diameter of the file.

An important step is what parameters of the teeth (chain), because it is for this that the files for the chain pitch need to be tapped. In standard cases, this diameter is 4-5.5 mm.

And the file is held at a clear angle of 90° in the plane (vertical), and 30-10° in the (horizontal).

Sharpening teeth using only files is a very labor-intensive process, and many people use other tools for sharpening, these are also kits that come in addition to the chainsaw itself, or if they don’t come together, they can be bought at a garden equipment store.

Now let’s take a closer look at the tools that can be used to sharpen chains:

A file (round) that is attached to a round holder.
A flat file that should be used to sharpen the stopper.
A template that provides the final operation.
A hook used to clear sawdust from a saw.

On the file (round) which is attached to the holder, there are special lines due to which it is correctly positioned relative to the chain and does not move to the side, and the plate rests as much as possible against the crown of the tooth, and thus the file becomes the cutting edge at the bottom.

Thanks to the holder, you will know for sure that the file at the correct height is adjacent to the saw tooth. And for every file with a holder, there are many holder options.

If you choose the right file with a holder, then you will know for sure that it comes into contact with the back of the tooth by 20% or 1/5 of the diameter.

During sharpening itself, you need to carefully strengthen the tire, and with smooth movements using a file with a holder, make 2-3 movements from yourself, for maximum effect.

To make the effect even greater, apply maximum effort to the file to sharpen it even more. Also, to protect it from wear, make turns so that it can be used from all sides.

We do this with all the teeth on one side, then we turn the saw and do the same on the other side.

The teeth also need to be made at the same length, you don’t need to sharpen one tooth 5-6 times, and the rest 2-3 times, do it the same way everywhere, so that the saw cuts well, it can also be due to an uneven stroke, it can often chip.

When we have finished sharpening the chain, we need to start sharpening the depth stop.

You need to put a template on it, namely so that it fits directly into the slot, then take a flat file and use it to grind off the end protruding from the slot itself.

When you sharpen the stop, the template should be close to where it says “Soft” (soft) or “Hard” (hard) wood.

And it should clearly fall into the slot, and when sharpening as with a round file, we make smooth movements, and with the help of a flat file we make the same movements from ourselves.

Examples of a couple of chainsaw sharpening machines

The entire chain, all the teeth can be sharpened using files if you get into the ground or sand, but if this process seems labor-intensive to you, you can use special sharpening machines.

Namely:

A company like “Stihl” produces two types of machines and 2 modifications of manual machines, the first is mobile (FG1) and the second is stationary (FG2).

They are installed on the tire.

These machines are very similar to crayfish saws, only a file (round) is used to replace the blade.

These machines, according to their principle, sharpen machines (FG1, FG2). and thus they are repaired by adjusting the edge to the same size, taking the smallest tooth by the head.

We do this on one tooth and move on to the next one, while the settings that you set remain unchanged, after you have adjusted the first tooth, this sharpening ensures that all teeth are uniformly sharpened to the correct size.

When we have already reached the limiter, we need to change the file (round) to a flat one.

There are also automatic (electret) machines, they have a system for setting up, which presses the chain, immediately takes the desired angle, and brings the disk to the stern which is sharpened, there are also machines that clamp automatically when you lower the disk to chain.

And you can also watch a video of sharpening a chainsaw chain

The quality of a construction tool is not just a matter of efficiency, but also of work safety. That is why you should carefully monitor the condition of the working parts of any tool, including chainsaws. It is necessary to sharpen the chain in a timely manner and it is not necessary to contact a specialist: you can carry out the entire process yourself. Below is a detailed description of the technology for sharpening a chainsaw chain with your own hands (video instructions are attached).

Sharpening a chain on a chainsaw: the need for the procedure and the subtleties of its implementation

In order not to waste your time in vain, you need to know for sure that the chain on the chainsaw is already dull. This is quite easy to determine. So, a well-sharpened saw gently and quickly enters the tree. If you feel even the slightest resistance while working with wood, this is the first sign that the chain is already dull and should not be delayed in sharpening it. The fact is that chain wear can affect very important indicators in the following ways:

tool productivity decreases;
fuel consumption increases greatly;
The chain links are overloaded, thereby reducing the service life of the tool.

Chainsaw

In order to properly sharpen a chainsaw chain, you need to have special skill, and it can only appear if you have an idea of the structural features of the saw. The fact is that the teeth of the chain have a rather complex and unusual structure, and accordingly, the sharpening process turns into a rather painstaking task.

So, the edge of the chain is densely covered with teeth, which have 2 edges: top and side. One chain link is represented by a base, a blade and a depth stop.

How quickly the saw chain becomes dull depends directly on the load on the tool and the conditions in which the work is carried out. So, all you need to do is hit the stone or ground with the saw a couple of times and you will have to sharpen the chain.

The best ways to sharpen a chainsaw chain

There are several ways to sharpen chainsaws, each of which has its own advantages and features. Further details about each of them.

Sharpening with a file

Sharpening with a file is one of the most common, simple and effective ways to sharpen a saw. Most often, specialized stores sell ready-made kits (sometimes together with a saw) for sharpening electric and chainsaws. The simplest set consists of the following elements:

a cylindrical file installed in a holder;
flat file;
hook and template to determine the desired stopper depth.

Sharpening with a file

Use a file to sharpen the teeth of the chain carefully, smoothly, without putting excessive pressure on the tool. It is advisable to secure the tire before starting work. After this you can start working. So, we install the holder on the tooth being sharpened, hold it in one position and lightly press the file against the edge being sharpened. After this, we make several smooth movements from ourselves.

We repeat the process in a similar way with all the remaining teeth. It should be remembered that all teeth must be sharpened equally. This can be achieved by using the same force to sharpen each tooth and performing an equal number of movements.

Advice. During the process of sharpening chain teeth, it is necessary to periodically turn the file in a circle. This will avoid severe wear of the sharpening tool on one side.

Sharpening with a grinder

This method is considered one of the simplest and most accessible, but with one caveat: if you have a grinder at hand and know how to use it. Otherwise, the sharpening process may not be so simple.

Sharpening can be done using a grinder

The peculiarity of this sharpening method is that the chain does not need to be removed from the saw while sharpening its teeth. For sharpening, you should prepare a previously used metal disc with a thickness of about 2.5 mm.

The grinder should be set to minimum speed, and the process itself must be carried out, gradually moving in order from one tooth to another.

Sharpening on a machine

Unfortunately, in some cases, manual sharpening of teeth is not enough. This occurs when the saw has been used so often and without regard for the consequences of careless use that the edge of the blade turns into something shapeless. It is for such cases that a machine can be considered the best option.

To sharpen chain teeth, one of the following types of machines is most often used:

Manual machine. This is more of a special device than a machine. The working part of a manual machine is similar to a bow saw, however, a cylindrical file is used here. The mechanism of such a machine is quite complicated, but with careful adjustment it is capable of completing the sharpening process in the most precise manner.

Saw sharpening machine

Electric machine. Sharpening is carried out directly by an abrasive disc built into the machine. Automatic tuning allows you to set the optimal parameters quickly and in the best way. In addition to the machine, in some cases there is a protective mask that will prevent sparks and chips from getting into your eyes.

That's all you need to know in order to sharpen your chain quickly and competently. Good luck!

How to quickly sharpen a chainsaw chain: video

Any instrument needs timely care. A chainsaw is a type of equipment that requires special attention. The device poses a certain danger, but if the chain is blunt, then the risks increase significantly.

During intensive work, the need for sharpening arises often. Therefore, it makes sense to learn how to restore its functionality, since sharpening a chainsaw chain with your own hands is not a difficult operation, but having mastered it, labor productivity will increase, as well as work safety.

How to sharpen a chain on a chainsaw with your own hands

Determining when a tool needs servicing is easy. This becomes clear during the work process based on the following signs:

the chips become small;

requires significant effort;

the saw jams;

strong vibration is felt;

cutting time increases.

Taking a closer look at the chain, you can visually verify that the edges do not have the necessary sharpness. Having discovered that the time has come to sharpen them, you cannot postpone this procedure. Firstly, the work becomes unsafe for the performer. Secondly, there is an unwanted load on the power unit. And thirdly, a lot of time is lost, some of which is better spent on sharpening.

The sharpening principle is based on the design features of the link. It consists of a body on which an L-shaped cutting edge is located. The vertical edge is straight, and the horizontal edge is made at an angle. There is a cut depth limiter in front of the tooth. All these elements need processing.

Grinding the cutting part reduces the height of the chain profile. If the height of the stop is not removed at the same time, it will not allow the tooth to sink into the wood to the required depth, so it is also ground down. Editing of the stop is done in significantly smaller volumes.

The cutting edge decreases in height by fractions of a millimeter when sharpened. This is the value you need to focus on when processing the limit stop. For work, you can use a file, an angle grinder (grinder), special mechanical devices and electric tools.

Sharpening with a file

To work, you will need two files: round and straight. The first is chosen according to the oval in the link body. Diameters more than 6 mm There are no household chainsaws on chains. Usually this size does not exceed 5.5 mm. A larger file cannot be used. It will change the geometry of the cutter.

There are two main technologies for manual sharpening. The simplest method is when the file is controlled visually. The master follows the factory processing angles as much as possible and carefully processes the vertical edge under full visual control.

The tool partially touches the horizontal edge. Then, using a flat file, it is brought to the desired state and lightly passed along the limiter.

The second method is more accurate and productive; sharpening chainsaw chains with your own hands using a file is done using a special holder for a round product. With such a device, sharpening a chainsaw chain with your own hands becomes easier.

It is configured so that both faces can be processed in one pass. The file moves vertically across, and horizontally along the cutting edge. The device significantly reduces sharpening time and makes it better quality. The depth stop is removed with a straight file. Despite the technological difference, there are general rules for both methods:

the chain must be fixed in a vice;

the angle of the file relative to the bar is maintained (about 30°)

done 2-3 movements from yourself with the same effort.

You can make a device for sharpening chainsaw chains with your own hands in a maximum of an hour. The photo shows the factory device. Making the same thing at home is not difficult for the average home craftsman.

Electric sharpening machines

The most accurate and efficient way to restore a chain is to use specialized equipment. This is a machine for sharpening chainsaw chains with your own hands.

It costs quite a lot, but it completely eliminates the human factor and errors during manual sharpening. It is advisable to purchase it when the volume of work to be done is significant. However, there are budget models that are available to many owners of country houses and dachas.

It is necessary to set the angle of the chain and the abrasive wheel and the pitch of the links. Manufacturers offer several types of mechanisms for securing the chain. Recommendations for a specific model are in the user manual. Bring the device to the edge slowly.

It is recommended not to make a pass more than 2 seconds. If it is not possible to complete the treatment at once, the abrasive wheel is removed and after a short period of time the tooth is sharpened again. In this way, it is possible to avoid overheating of the metal, maintaining its performance qualities. The product passport indicates which saw blade should be used for the machine.

How to sharpen using an angle grinder

The method requires skill and skill. Unlike a sharpening machine, there are no limiters. The technician is required to be careful and comply with safety regulations. It is better for experienced people to use this method. The grinder (angle grinder) is pre-secured on a table or other stable place.

It is better to make a special clamp for this. After fixing, check whether there is vibration by turning on the tool in test mode for several minutes. If conditions are satisfactory, work can begin. Do-it-yourself chainsaw sharpening with a grinder is done directly bringing the link to the abrasive wheel.

In conclusion, we can say that no matter how you sharpen a chainsaw chain with your own hands, the main thing is the accuracy and precision of the master. With manual processing, angle errors and uneven grinding of the metal are possible, while with machine processing there is a risk of injury.

Today there is practically no man who does not have such a unique and powerful tool of its kind for gardening and construction work as a chainsaw (see). In fact, this device is the best mechanism for performing complex and large volumes of work, for example. Its power is enough to carry out its activities for at least twelve hours practically without stopping (see). Therefore, it is not at all surprising that in our time chainsaws have such a high level of popularity and demand. But, despite all its positive characteristics, this device, or rather its integral part, such as The chain may become dull due to long use. Naturally, as they say, it’s not a big deal, since you can sharpen it very simply and quickly with your own hands.

This is the topic that this article is intended for. Here you can learn about the direct mechanism of the chain, as well as how and through the use of which you can quickly sharpen “your tool” for work. You will also be presented with a couple of tips that will definitely be useful to you. So, let's begin to consider this topic.

Chain structure in a chainsaw

In fact, the circuit is quite simple. One of its main elements are the teeth, which are located on both the left and right sides, and which alternate. They are connected to each other through other links, namely connecting ones.

They are made directly from specialized steel material. In addition, the upper part of the steel is coated with a hard chrome coating, which significantly increases the service life of the chainsaw. Also Important parts of the chain of this type of tool are:

cutting link;
side and top edges;
depth shear limiter.

Now let's try to understand the issue regarding the reasons for the blunting of the chain itself. Why does this happen and what factors influence it. This issue is quite serious, since the productivity of the chainsaw itself depends primarily on the sharpness of the teeth on the chain. So, let's take everything in order.

If you own a chainsaw and are working feel strong vibrations from the instrument, and notice the slow movement of the tool, then be sure that the chain on your device is dull. This is mainly caused by intensive and excessive use of the tool.

In addition, contact directly with the ground or with much harder wooden elements is important.

In addition, it is worth noting that working with such a chainsaw is highly undesirable, since this kind of negligence can lead to significant problems. Among which are not only significantly high fuel consumption and very slow cutting, but also the impact of vibrations directly on the body, and this, in turn, leads to breakage of the sprocket and even the tire itself.

How to sharpen a chainsaw chain with your own hands

Now let’s actually look at all the direct ways by which you can produce high-quality, and most importantly, correct sharpening of the chain itself located on the chainsaw. So.

How to properly sharpen a saw chain with a file

The main advantage of this method is its cost-effectiveness, since, in fact, the file is quite inexpensive. Moreover, it is most likely that this kind of tool is in the arsenal of any owner. But it is worth noting that not every file can be suitable for sharpening, since first of all, or rather its diameter, must correspond to the width of the chain itself. For that To make it easier for you to navigate, we present the following indicators:

If the chain size is 1.3 mm, then you need a 4 mm file;
If the chain diameter is 1.6 mm, then a file with a size of 5.2 mm;

A flat-shaped file is also used directly so that you can use it to remove the so-called limiters that the cutting teeth have.

It is worth noting that the process of direct sharpening itself must be carried out at a certain immediate angle on the cutting tooth. It is important that Each tooth of the chain has a factory cut, in fact, on which data is indicated about exactly what angle this manipulation should be performed.

In addition to the tooth itself, which cuts directly, each chain link has a certain kind of limiter, which actually determines the permissible depth of their entry into the wooden material. It is worth noting that sharpening of these particular limiters should be done extremely rarely, moreover, only when necessary.

An important role in the immediate sharpening is played out by the so-called clamp. Which is a kind of mechanism designed specifically for fixing and directly securing the saw bar. Basically, it is hooked either to the extreme corner of the table or to a workbench. Since a perfectly installed saw is a guarantee of high-quality sharpening.

Also of no small importance is the pattern, which has specific rollers directly for moving the saw and is attached specifically to the saw bar. You can choose the angle of direct sharpening yourself, after which you fix it using a pattern.

The process itself is up to you chaotic movement through a file directly in the groove of this type of device. It is worth noting that such a “tool” will reduce to a minimum the possibility of incorrect sharpening.

Using an ordinary grinder

Most owners avoid this method of directly sharpening the chain, as they believe that such a tool can seriously damage the cutting teeth. Moreover, this method is the most complex of all existing today. Such fears are not, as they say, taken out of thin air, since in fact, a chainsaw can cause harm, especially if you are a beginner in this matter.

It is for this reason that if you are going to carry out this kind of manipulation for the first time, the best thing you can do is to use the method presented above. But, nevertheless, we will still introduce you to the immediate features of a chainsaw using this method.

Sharpening a chain using a chainsaw machine

And so, in the process of sharpening do not remove the chain from its place, since the manipulation is carried out using a chainsaw. It is also important that it is necessary to use a special disk that can work with metal material and the diameter of which must be at least 2.5 mm. But remember that under no circumstances should the disk be new, but rather used and have rounded edges.

It is also important that you yourself can determine immediate angle, through which sharpening will be carried out. Remember that between the chain and the bottom of the tire you need to install a wedge, namely a wooden one. This process requires direct skills. This is a very effective method and through this type of sharpening the chain can last you from 4 to 7 such manipulations.

Take a look at the video:

Correct sharpening using a manual machine

Every owner who has been using a chainsaw for a long time knows that not all chains can be sharpened using a file. For example, if the chain cutting edge, through frequent use of the tool, has simply lost its original shape, then in this case, you are unlikely to be able to bring it back to life, at least such a process will take you not only a lot of time, but and strength.

That is why the best way is to use it directly. They are either electric or manual, equipped with either sharpening wheels or a sharpening stone. This kind of method may not be new, but nevertheless it is quite effective and accurate.

Now let’s actually get acquainted with the process of such sharpening itself. The first thing you should do is to directly loosen the chain clamp adjustment screw. After which you need to install the chain itself in such a position that the links that are on it are turned directly to the sharpening stone.

Then decide on the actual angle at which sharpening will be done. It is important that this kind of “turning” can be done using two methods. Namely:

The first method is sequential sharpening, which consists in the fact that you need to act on each tooth separately, while periodically changing the immediate polarity;

The second method is sharpening, but only every second tooth. For example, first you sharpen the right tooth, and then the left. It is worth noting that this method does not involve a direct change in polarity.

First of all, you must remember that before you carry out direct sharpening, you need to determine its level, starting from the most, let’s say, “dumb” cutter, since it is a kind of guideline in this process.

It is also important to remember that no need to get too carried away with manipulation and grind your chain deeply. Since in this way you will simply disrupt its direct functionality, and its immediate strength and the strength of the link will decrease as well.

It is also important that most experts recommend, after direct sharpening, to blow through the chain itself using compressed air. And after this process, place it in a container for several hours, but it must be clean.

To sum it up...

In this article, you learned how to sharpen a chainsaw chain at home using different methods. In fact, as you have already seen, the sharpening process itself is not difficult, the main thing is to have the necessary tools, patience and follow all the tips prescribed above. And then your chainsaw will perfectly fulfill its intended purpose for many years to come.
