Jumped up the chain on the chainsaw how to dress. Ways to check the degree of tension

Jumps out of the tire chain

The chain tension on chainsaws plays a large role in ensuring the normal performance of these tools. In the case of a poor stretch of the circuit, it is very easily damaged or slipped from the guide tire during the saw process.

If you wondered why the chain flies on your chainsaw, then there are some problems in the mechanism. There are three main causes of this problem: improper functioning of the tire, stretching the chain and poorly fixed led star. We will analyze in more detail each of the possible reasons for the breakdown.

Problems with the bus

If problems with the tire occur, the stretch of the chain almost always weakens. Usually this problem occurs at the site of tire attachment.

This place is in the groove between the outer plate, which is located on the casing of the chain headset and the internal plate located on the engine body. The casing with the bus is fixed by a bolt. This mount is called the “engine knot”. Leading star and tire mounts are protected by special lids.

If the fixing bolts are weakened, the tire begins to move or vibrate. If the tire is serviceable, then the chain stretch should be normal. After stretching, she will walk at least five working days without suspenders. Therefore, you need to carefully clamp the bolts that holds the tire.

Did you know? In the city of Nora, which is located in Canada, a tanning ribbon thread is highly developed. All the streets and squares of this town are decorated with products that the masters of chainsaws created.

To understand how to pull the chain on the chainsaw, first you need to find and lower the chain brake. The tension screw is located next to the tire, it is turned until the chain is stretched onto the tire. Then pull the chain in the direction of the clockwise. If it does not move, then it needs to be a little weaken, checking the tension screw in the opposite direction.

The chain stretched out

If you sag a chain on a chainsaw, then this indicates a malfunction of a mechanism, one of the options is the wear of the chain itself.

Over time, the metal is deformed and the chains become 0.5-1 cm longer. It is best to eliminate this problem with the purchase of a new chain, but there is a way to return the old one to work. Experts claim that this is very difficult and almost impossible, but we will tell you how to do it at home.

The usual chainsaw chains are made of strong steel, so it is difficult to disconnect it. You need to dissolve the chain on the inside of the rivet, which serves as a connecting mechanism.

First you need to fix the graders in a vice, and then gradually grind the protruding part. You need to grind a file or a file. It is not recommended to use corner grinder, since there is a risk of damaging the side parts of the links. After grinding, rivets are knocked out with a beard. A knocked out rivet should not be thrown away. Perhaps you cannot find her replacement. Manufacturers of gasoline saws do not produce individual parts for the chain, since they do not suggest that consumers will be able to repair the chain themselves. Most likely you will not succeed in making a new rivet yourself, so you have to install the old.

In order to shorten the chain, it needs to be divided in two places. But remember that the number of guide protrusions from the inside of the chain and the distance between them should be combined with the leading star.

Important! When welding the link, set the current to the minimum value. Pick up an electrode with the least diameter, so you will not hurt neighboring links.

After removing one or more links (depending on the degree of stretching of the chain), you can combine. We connect to old rivets, while tightly press them on the sides.

Next, we need a welding machine. The rivet must be welded to the side parts of the link. After that, we grind the excess that formed when working with welding. The chain can be considered again good.

A lawn mower and a gasoline trimmer for grass will help to maintain order in your summer cottage.

The leading star is poorly fixed

One of the possible options for a sagging chain on your device is a problem with a leading star. Most often everything happens due to the fact that the star is poorly fixed. Now we will tell you how to fix the star and then put the chain on the chainsaw.

First you need to remove the protective cover of the engine. Next, remove the protective cover of the candle, pull out the air filter. Then you need to unscrew the candle with a special key. A special stopper is put in its place, which fixes the piston in a certain position. A special key (you can use a universal key for an angular grinder), we twist the clutch disk clockwise until the piston takes the extreme upper position. If you look at the hole of the candle, then the piston should remain below. In the role of a stopper, you can apply a thick rope, it is better to fold it several times. After fixation, you can clamp the leading star, scrolling the clutch disk counterclockwise.

Did you know? The Friendship Basil got its name at the Honor of the three hundredth anniversary of the Ukrainian connection in 1954.

After clamping, you need to do everything in the reverse order, that is, collect a chainsaw. The grade is put on the tire, he must get to the leading star, which holds him. The tire is placed in special openings for fastening and screwed with bolts. Then the protection is put.

Tools necessary for work

Starting to the rivet, the first thing you need to remove the link from the chain, for this you need to plug the rivets. To rivet, you will need an anvil, a hammer, thin beards, a vice, an angular grinder with a grinding circle or a sandpaper. These tools do not allow you to work efficiently, but they will find them for everyone. A more cultural and careful way to remove rivets using a special punch.

There are several designs of the breakdowns, we will talk about the most popular.

Rubber for rivets

Punch. a machine used to remove rivets.

It is mechanical, works on the principle of the press. The kit has a special anvil in which grooves are selected for installing a headset with a different step. There are also interchangeable tips, which are squeezed out of the rivets.

Important: the size of rivets in different types of chains differs, so when buying a breakdown machine, make sure that there are several tips that are used for different types of headset.

We suggest watching a video that shows how to flan out a saw chain using a mechanical punch.

After the chain is flared up, it is necessary to remove the old link, install a new one and stuck. For this, the machine is used to rivet. It is electric, so it costs much more than a breakdown machine.

The rivet-probe machine

A gearbox with a high torque is installed on the machine.

It is used for riveting and rolling the headset in steps from 1/4 ″ to 0.404 ″. The depth of cut chains that can be stuck with this machine from 1.1 mm, to 2 mm (0.043 ″. 0.080 ″). Together with the machine, special rotating inserts and anvils for different types are delivered. Inserts and anvils are marked. Marking “a” means that the inserts are designed for a headset with a 3/8 ″ and 0.404 ″ step. “B”. for 1/4 ″ and 0.325 ″.

The machine works as follows. The saw chain with a new link and rivets is installed in the guide inserts. The repair link with rivets installed in it is pressed by a working roller to the anvil, after which the engine turns on and the roller begins to rotate, gradually crushing the rivet, at this moment, the machine operator slightly increases the force of the roller, tightening the adjusting screw. For clarity, we suggest watching a video about the work of a riveted-rolling machine.

Use such a machine in order to rivet at home is not profitable, t. to. it is expensive. If you need to block not regularly, then you can do without it. Consider how to shorten the chain of chainships with your own hands without using expensive machines. You need to start with riveting and lifting the link.

The advantages of the machine are that the rivets stained with its help are practically no different in quality from those that riveted in the factory.

Why the chain flies?

These problems relate to both gasoline and electric saw. If a chain flew during the work, then there are several reasons why this happens:

Problems with the bus

If you revealed that the chain flies due to problems with the tire, then the reason must be sought in the place of its fastening. The groove is located between the plate on the chain headset and the other plate on the case itself. Mounting with a bolt is called a motor node. In all models of the chainsaw, the tire mount is hidden under the plates. Over time, the bolts are loosened and keep not so tight, so the vibration of the tire increases.

The device of the saw tire

If, upon visual inspection, you determined that the chain tension is good, the work of the saw also does not cause complaints, and the tire is loose, then it should be fixed and tested.

Substance of the chain

Over time, it becomes noticeable that the chain begins to sag. Like each tool or spare parts, the chain has its own service life, after which it is necessary to conduct inspection and it is possible to repair. Since it is the chain that is subject to the greatest loads, it can not only stretch, but also dull. You need to shorten the saw if you have already opened the adjustment screw. Usually remove no more than 1 or 2 links.

Stretching occurs for the following reasons:

• There were malfunctions in the oil pump due to violation of oil supply or its complete absence. When heated, the chain is subject to stretching to a greater extent.
• Adverse conditions during work. Dust, dirt and sawdust fall on the saw set of headset, polluting it and acting as an abrasive. Over time, the attachment points of the links are wiped and the chain stretches.
• If low.quality oil is poured for lubrication of the chain or working out from the engine of the machine, then the particles that are present there also act as an abrasive.
• After a while, the chain is stretched naturally.

The main problems of the chain of the chainsaw

Those who have encountered such equipment know that all types have a special brake. It looks like a large pen that is pushed to block rotation. People without experience can forget about this feature, and during the file they will not remove the lock. The operation of the tool with this approach will be the result of a breakdown of brakes or clutch. In this case, it is not difficult to diagnose the problem, however, there are situations when the chain weakens. Some cannot understand why the chain flies on the chainsaw during sawing.

There are several reasons for this malfunction:

• Using a fresh chain and old stars. These two spare parts are involved in the cut at the same time, and their replacement is carried out evenly. So you can avoid troubles and achieve the best effect;
• The running.in is not taken into account. After installing the element, you should start the engine and “drive” the saw at small and medium speeds. All links will be lubricated with this effect, but the stretch will weaken. Further, before a repeated suspension, the mechanism is given time to cool;
• Low quality of products. In the construction market you can find many manufacturers, among which fakes often come across. Therefore, such purchases are advised to treat carefully;
• long use and lack of oil. From this, iron begins to overheat, and it loses all its properties (including elasticity).

Melting chain brake cover

Sixing the chain

These are not all the signs due to which troubles may arise. The key is the correct tightening. It is not difficult to make it, however, if you miss the slightest part, the chain will constantly subside. This can cause damage to a specialist. You can reduce the likelihood in one way: clearly observe the actions of the diagnosis and change of the chain.

An important point is the operation of the unit in the winter period. In this option, you need to install an additional filter that protects the main details from snow hit. To start and warm up, you need to remember about the suction and air damper, and store the tool in a warm room. If you neglect these rules, the low temperature will freeze the remaining liquid and dirt on the surface, which will lead to engine starting problems. Still sharp changes in temperature and humidity will have a destructive effect on all iron components.

Most of the part is made, and it remains only to carry out adjustment. To do this, you need to take a “flat” screwdriver and turning the appropriate design (in most models it is located below the casing bolts) to adjust. The chain stretch is made so that its lower side does not sag, and there was a free move along the axis. After the bolts on the case are clamped.

Important! To avoid hands injuries, all procedures are recommended in special dense gloves.

Many inexperienced workers do not pay attention to the position of the guide and perform fixation in an arbitrary position. However, during the cutting period, pressure occurs on the lower plane, which shifts and creates sagging. In order to avoid this, the configuration is advised to carry out with a guide tire raised upward.

Some wonder how to pull the chain on the Stihl chain from the German manufacturer. The fact is that the regulator of this manufacturer is made in front (next to the outer part of the guide), which creates bewilderment. All other actions are made in the same way and in the same order.

Of course, instructions are attached to the kit of most models on how to properly pull or replace the chain on a chainsaw, but many points are not indicated in it. Also, a large number of consumers prefers to buy secondopiles of used to save a significant part of the cash. And the past owners are unlikely to keep such trifles as the leadership.

Tools that are needed to pull the saw

First of all, it is necessary for elementary baggage of knowledge of working with mechanisms. In general, it all depends on the type of saw that you use. For example, in a rod, the tension is very simple. There is a built.in tensioner. The next list of actions will help to do everything correctly:

• The star lid is removed with a lamb nut;
• Rotating the adjusting wheel, sufficient tension is determined independently;
• The cover is closed, and the chain is fixed on the tire.

The chain of the chain of the chain if in the chainsaw, such as Sparky, is not provided for the tension mechanism, then the following actions must be performed:

• To twist the screws with a hexagon and remove the case;
• Unscrew the screw and get a nut;
• Polish the disk that part of the screw that adjacent to the saw case;
• Collect the saw in the reverse order;
• Peel.

Chains for chainsaws. lubrication, sharpening, stretch, types, shortening

A chain is an important attribute of any gasoline or electric saw. The effectiveness of the tool, as well as the amount of fuel consumed by it, depends on the serviceability and state of this part. Often it can be difficult for a beginner to determine which chain for a chainsaw is better. In this case, it will be necessary to study the basic characteristics of the saw headset, as well as the rules for its installation and maintenance.

What are the chains for chainsaws?

Today the market is full of many varieties of saw elements. They are divided by their characteristics and are divided into several categories.

According to the type of sawing, such types of details are distinguished:

• Transverse. a saw set of this type is characterized by the effect of smoothing vibration and reducing the load on the engine engine. This makes the use of the saw more simple and comfortable;
• longitudinal. details of this type are highlighted by high performance.

Another important characteristic is the step of the chain of the chain.

According to this factor, the saw set is divided into such types:

• 0.25 or 1/4 ”. one.handed household saws are equipped with these details;
• 0.325 or 3/8 ”. elements with this step are most often equipped with semi.professional tools;
• 0.404 or 3/4 “. such parts are suitable for use by concrete or aerated concrete.

As a rule, the performance of the headset directly depends on the step.

The third characteristic is the thickness of the shanks. To install the element, this parameter needs to coincide with the size of the grooves in the tire of the tool. Thus, the headset will be firmly fixed on the tire, and the risk of its accidental slipping will be minimized.

The following types of details are found on sale:

• chains, the thickness of the tailings of which is 1.1 mm. these parts are used to work with household tools;
• elements, the thickness of the tailings of which is 1.3 mm. the headset of this type is used to equip semi.professional chainsaws;
• products, the thickness of the shanks of which is 1.5 mm. are used for regular equipment of small, but powerful household tools;
• details, the thickness of the tailings of which is from 1.6 to 2 mm. this headset is mounted only on powerful industrial saws.

Many experts also divide the working bodies, if possible, installing them into a chainsaw with an independent sharpening function. Based on this property, a self.adjusting headset or a chain, which must be hidden manually, can also be found on sale.

How to choose a chain for a chainsaw?

The study of several important factors will help to choose a chain for a chainsaw for a chainsaw.

• The material of the headset. the most reliable will be products, in the production of which highly alloyed steel is used using nickel and chromium. For the possibility of sawing of particularly solid wood, it is best to choose a headset with winning attacks. It is important to take into account that the winning chain for the chainsaw is high in weight, so it needs to be installed only on a high.power tool. About the material from which the part is made will tell the marking on its cutting teeth;
• the number of links. the efficiency of the product depends on this parameter. To determine the number of elements, you need to calculate the teeth of the saw headset;
• The depth of the cut. this parameter depends on the height of the profile of the chain tooth. Today, buyers can choose one of two options. parts with a height of teeth 0.635 mm or a product, the height of the teeth of which is 0.762 mm. Products of the first type are used to equip household saws. Elements of the second type are installed on powerful semi.professional and industrial tools;
• chain length. directly depends on the size of the saw used. Suitable dimensions of the headset are usually indicated in the instrument operation instructions;
• The direction of the sawing. the buyer will need to determine in advance how exactly he will saw the wood. along or across. Each of these cases uses headsets of different types.

In the event that the buyer cannot independently determine the step of the chain of the chainsaw or its other important parameters, then you can use the available chain selection table for popular chainsaws.

How to pull the chain on the chainsaw correctly?

The chain stretch on the chainsaw can be performed in two ways.

• The traditional method of tension using the tool. to install the chain on the chainsaw, you will need a standard key, which is almost always supplied with a gasoline saw. The first side of the key is working, which is unscrewed by the nuts. The other side of the key is a slotted screwdriver. To correctly put the chain on the chainsaw, you must first weaken the nuts that are located on the lid covering the location of the standard tire. The main thing is not to rush, and slowly tighten the headset, regularly checking it with your hands. To do this, with one hand you need to slightly pull the part in the lower part of the factory tire. After adjustment, it remains to tighten the nuts in the lid;
• tension without tools. with this way, putting the chain on the chainsaw is easier and faster. To do this, in the side of the saw there is a factory tensioner. By its rotation, the operator will be able to control the position of the headset on the tire.

As soon as the installation of the chain on the chainsaw is over, you need to check it. With optimal tension, the headset will not sag in the lower part. If you pull the chain from the tire, then the internal teeth of the parts should exit the regular tire grooves by about 5 mm.

Chain. an important element of the chainsaw structure. It is on it that the greatest load is on the time, so high.quality and systemic care is required.

When using any model, it is important to know how to wear a chain correctly, monitor its stretch. If you fix it incorrectly, there is a risk of stretching and leaving the grooves.

The productivity of the saw is reduced, and the risk of injuries at high capacities is also increasing.

Why the chain flew?

There are several reasons why the chain can fly during operation. This may be due to the improper operation of the tire or insufficient stretch. The problem sometimes appears with an insufficiently fixed lead and led star. Determining the reason allows you to accurately choose the required repair, tools.

The tire weakened

With a decrease in the tension of the chain, the problem is often accompanied by a weakening of the tire itself.

To check its condition, you need to inspect the place between the upper plate on the casing of the headset and the inner surface on the case.

When weakening fixing bolts, the tire begins to move, which can be seen by characteristic vibration during sawing. With frequent operation, it is recommended to regularly clamp the bolts.

If you yourself decide to tighten the tire, then you need to find and lower the chain brake. Turn the tension screw so that the chain is tightly in the grooves. After that, pull the chain in the direction of movement, if it is too tight, loosen the screw.

Important! The weakening of the tire is observed in both professional and household models of chainsaws. With intensive use of the tool, check the tension before each launch.

The chain stretched out

Figure 2. the chain on the chainsaw was stretched

• Any functional changes in the chain lead to a decrease in the productivity of the tool, injuries during operation.
• It should be regularly ensured that there is no deformation of metal and stretching more than 1 cm.
• If such a problem still arose, you need to purchase a new chain or adjust the old.
• Disconnect the links of the chain on the machine or fix it in a vice, hid rivets with a file and knock them out using a beard (it is not recommended to use a corner grinder).

Delete 1-2 links depending on the degree of stretching of the chain. After that, put all the elements in place, insert a rivet and beat it with a hammer, use a special riveting tool. For reliability, it is recommended to use a welding machine.

At the end of the work, to flow excess and burrs with a thin suction.

Problems with the leading star

Sometimes a sagging chain occurs due to problems with the leading star. The most common situation is when it is poorly fixed. A step.by.step algorithm to twist the asterisk:

• Remove the protective cover of the engine.
• Remove the air filter and unscrew the candle, putting in its place a special stopper for fixing the piston in real estate.
• The key for the corner grinder scroll the clutch disk clockwise to the maximum upper position. Check the density of fixation of the asterisk, adjust its position.Figure 3. Leading star on a chainsaw

After clamping, collect a chainsaw, be sure to put on a protective casing. When assembling, check that the chain is tightly on the tire.

How to put a chain on a chainsaw correctly?

In most models, the chain is easy to put on the tire by unscrewing the main screw, then the links must be placed on the leading star.

Before starting work, the general condition of all cutting surfaces and the guide groove and the installation wheel should be inspected.

Often, dirt and small shavings accumulate in it, which will subsequently lead to planned repair, worsening sliding. Step.by.step work algorithm:

• Free the screws fixing the protective cover of the asterisk, it usually twists with the help of a lamb nut.
• Turn the stretch star to the right until it stops.
• Put the links on the headset starting from the top. Get to get into the appropriate grooves.
• Fix the fastener of the chain star, tighten the nut. Guides must get into a special gutter.
• Release the chain brake, pull the circuit along the line for checking the tension. If necessary, twist the tensioner lever.Figure 4. setting the chain on the chainsaw

The installation wheel should freely scroll after installing the chain of the chainsaw. At the end of the work, it is imperative to lubricate all the moving elements of the tool to avoid quick wear.

Important! Installation of a headset should only be carried out in dense protective gloves. This will protect you from injuries and cuts with sharp edges of the cutting edge of the teeth.

How to install a tire with a chain on a chainsaw?

Often, problems in the operation of the chainsaws occur with improper installation of the tire. This can be determined by the characteristic rattling, vibration and low saw productivity during operation. The tire attachment to the case is between the external plate, the fixation is carried out by a special bolt.

The people call this part “engine unit”, it consists of a drive star and stop bolts. It is not difficult to install the tire along with the saw. you need to remove all the protective covers, unscrew the fixing bolts by a third of the length and put the headset. Then tightly pull all the nuts, twist the tensioner with a special lever.

Tire installation on Stihl and Husqvarna

Models of chainsaws from the manufacturer STIHL I can differ in the assembly process. Step.by.step guide:

• Open the lamb nut, remove the protective cover of the chain star. Turn it on the tire to the right.
• Put the chain on the tire, starting from the top, the cutting tooth on the upper side should look strictly forward.
• Attach the assembled tire to the chainsaw, pull the design onto the asterisk. Pour the guide on the bolt with a loop. Close the lid, falling with pin into the holes provided by the manufacturer.
• Turn the lamb nut until the star lid touches the engine body.
• Turn the clamping bolt forward, leading links should get into the grooves of the tire. Fully tighten the lamb nut.

Taking a machine with a machine

The methodology using an electric machine that allows us to achieve factory accuracy is considered the most effective. We will figure out how to sharpen a chain of chainsaws in this way, achieving the desired result with minimal temporary and labor costs. The saw is placed in a special hole. It is necessary to loosen a screw closing a circuit and configure the desired sharpening level on the tables or the stupid tooth itself. The process is performed in accordance with the selected parameters, after which the saw is processed with machine oil. You can use two methods when sharpening with a machine:

• Consistent effect on the teeth one by one, from time to time changing the polarity.
• The teeth are hidden through one, first the right, and then the left one, which allows you to do without changes in polarity.

Poorly fixed leading asterisk

One of the possible sagging options on your device is the problem with the leading star. Most often everything happens, because the star is poorly fixed. Now we will tell you how to fix the star correctly, and then put the chain on the chainsaw.

Read how to cut ceramic tiles on the wall

First you need to remove the engine cover. Then remove the protective cover of the candle, pull out the air filter. Then you need to unscrew the candle with a special key. A special plug is placed in its place, which fixes the piston in a certain position. Using a special key (you can use a universal key for the Bulgarian language), turn the clutch plate clockwise until the piston reaches the extreme upper position. If you look at the hole of the candle, the piston should stay downstairs. In the role of a traffic jam you can apply a thick rope, it needs to be folded several times. After fixing, the leading star can be clamped by scrolling the clutch plate counterclockwise.

After the clamp, you need to do everything in the reverse order, that is, collect a chainsaw. The chain is worn on the tire, it should go to the leading star, which holds it. The tire is placed in special openings for fastening and bolt. Then put the protection.

How to adjust the degree of tension of the headset with a non.clock system

Increasingly, owners of new chainsaws contact the service centers with the question of how to adjust the tension of the chain on the tool with a non.clue mechanism. Today, manufacturers of chainsaws improved the mechanism for adjusting the tension of the cutting headset, thereby excluding the need to use keys and screwdrivers.

If the unit is equipped with a modern tension mechanism, then to set up the chain will need to carry out manual movement of a special wheel. The movement of the wheel contributes to the shift displacement, which is achieved due to a special mechanism consisting of a star and a stretch washer. The main advantage of such a system is that adjustment is performed without the use of additional tools, which means that the time spent on the procedure is reduced. Only the disadvantages of such mechanisms are much larger:

• The complexity of the design, which contributes to the occurrence of breakdowns, as well as difficulties with setting.
• Difficulties with installing a saw set.
• Small adjustment stroke, so a slightly stretched circuit cannot be pulled, as in the case of conventional tension mechanisms.

The method of adjusting the degree of tension on the chainsaws with the non.closing system is also called the non.conductive method. In fact, it is much easier to cope with this system, but the most important difficulty is that with a slight wear of the headset, it will need to be replaced.

Interesting to know! Experts recommend better not to reach the chain than to pull. When it is plugging, an excess load on the engine occurs. In addition, the degree of friction between the tire and the chain increases, and as a result, they heat up stronger, and wear out faster.

Reasons. why the chain weakens on the chainsaw

Often beginners are interested in why the chain tension is periodically weakened on the chainsaws? Everything has their own explanations, and therefore, to understand how often it is necessary to adjust the tension of the headset, we will understand in this matter in more detail.

The reasons for the weakening of the chain tension on the chainsaws are as follows:

• When working with the tool, colossal temperature loads are experienced not only by the engine, but also by the cutting headset. The effects of high temperatures leads to the expansion of the metal, and as a result, its elongation. Repeating the process of temperature fluctuations contributes to the fact that the chain is gradually lengthened due to the expansion of the metal.
• The links of the chain are interconnected using bushings. The boring holes for bushings at each link has an increased diameter, due to which the backlash is provided, and the ability to fold the chain in the ellipse. When moving the headset, it increases the length due to the increased diameter of the holes for the bushings. During operation, the tool diameter of the holes for bushings gradually increases, which helps to lengthen the headset.
• The chain is stretched not only due to its natural wear, but also with the edges of the leading and driven stars, as well as the groove of the tire. Licking the upper edge of the tire contributes to the fact that the tension of the chain decreases on the chainsaw.

As you can see, the reasons why the chain tension decreases on the chainships more than enough. Working a tool with a slightly stretched or tattered chain is strictly contraindicated. To achieve the efficiency of work with the tool, it is necessary to first maintain its maintenance.

Interesting to know! When running a new tool or when installing a new chain on a chainsaw, it is important to understand that checking the degree of tension must be checked every 30 minutes of work. After all, in the process of grinding a new headset, its accelerated wear is observed.

Summing up the above, it should be noted that a certain interval for checking the quality of the chain tension does not exist, does not exist. Each master should independently understand when the headset needs to set up. Drinking wood with a dull set of settings contributes to its speedy stretching, so it cannot be limited to certain terms. It is better to double.check the readiness of the tool for work than to get to the hospital with serious injuries.

How to pull a chain on a chainsaw

Before pulling the chain, refer to the instructions. it is spelled out in detail how and what you need to pull it. Depending on the model, the tension may vary. If there is no instructions or it is in another language, use our methods. They will be below.

Consider two types of chainsaws. classic and with a tension adjustment handle.

• Take the key from the kit, its shape resembles the letter T. The key has two work sides: one for unscrewing the nuts, the second. a screwdriver. to rotate the tension bolt.
• First loosen the nuts of the lid, but do not unscrew them.
• The second side (screwdriver) rotate the tension adjustment screw. It is located near the nuts.
• Scroll the screw clockwise until the sagging of the chain from below is about five millimeters.
• Twist the nuts.

Such models are less popular. they are put only on expensive equipment. On the side of the cover is the handle, during the rotation of which the chain will be pulled or weakened. Close. tension, against. weakening. Again, get sagging no more than 5 millimeters.

Before starting work, you need to check once again how the chain is stretched:

It should sag by ± 5 millimeters. Check with your hand how it goes. scroll it. The course should be easy.

Worst of all, if you pulled the chain. Weakly stretched chains fly quickly and make themselves felt. The tattered chains do not make themselves felt immediately. you may not even notice the difference for a long time, but the wear of the details will increase.

How to understand that the chain needs to be pulled?

Firstly, by external inspection-the chain sags from below, and is shifted at the top to the side. Such a chain is slightly stretched. She wear out faster, can distort or slip during operation. With a sagging chain, a tire, asterisk and a saw canvas wear out faster. If the chain slides, the tire can get stuck in the material.

Try to scroll it. She should go without much effort. If not, weaken it. Correctly pulling the chain means that it should not sag, but it should not go hard.

When it is pulled, it is more difficult to turn it to the engine. The wear of the chainsaw elements also increases, in particular, shaft and stars. The latter’s teeth are erased stronger, so with a tattered chain it will be necessary to change the stars more often.

often monitor the tension of new circuits. they stretch after first use. If this is not done, as we described above, the wear of the elements of the chainsaw and the chain itself will increase. Investigation is also increased.

How to carry out repairs

If the reason is associated with weak tension, it is necessary to tighten the chain slightly. And it does not matter which chain on YT4334 01 or other models. Their device and the principle of action are the same. To eliminate the malfunction, they act as follows:

• Weaken the nut that fastens the tire.
• Using a screwdriver, twist the adjusting screw next to the tire.
• Then tighten the nut.
• Check the move. it should be smooth, not too tight, but also without sagging.
• If necessary, adjust and check again.

There is also a problem in which the chain on the electric saw is not lubricated. The main reasons are associated with clogging the oil filter, tube or malfunction from the oil pump. In these cases, they act as follows:

• Remove the protective casing.
• Remove the tire, chain.
• Clean all the holes through which the oil is supplied.
• Then you need to understand how to assemble an electric saw. For this they perform the same actions, but in the reverse order.

It is not recommended to start work immediately. At first it is better to make sure that the oil does not proceed anymore, since it should only act during operation. To do this, put a sheet of paper on the table and turn on the lamp. Then connect the saw to the outlet and launched over this sheet. If drops of oil appear on it, then the problem is solved.

Fault prevention

Repair of electric saws can be carried out at home. But to avoid problems, it is recommended to observe standard preventive measures:

• Regularly clean and lubricate the filter using technical oil.
• If necessary, it is better to replace the filter so that the saw works properly.
• Before starting work, check the bolts and nuts. they should be tightened quite tightly.
• Regularly lubricate bearings and asterisk.
• Turn the chain in time. You can do this yourself with the help of a file or contact a master who works with a professional tool.

Thus, the chain almost always flies due to weak tension. You can eliminate the malfunction yourself. At the same time, do not pull it too tight. otherwise the chain may break.

How to put a chain and a tire on a chainsaw: Assembly

The procedure under consideration is quite simple. It is characterized by the following features:

• First, the chain brake is released.
• The tension screw is in close proximity to the bus.
• The next step is to pull the cutting element clockwise.
• If the circuit is difficult to move, then we have to weaken the fixing screw.

Modern chainsaw designs greatly simplify such work. Therefore, you can perform it yourself even in the absence of special tools.

When you need to pull the chain

Working with a strongly sagging chain is strictly unacceptable.

During the saw, the chain can break the groove of the tire, disable the teeth of the driven star.

The jumped chain can damage the details of the mechanism. But the most dangerous is the operator’s injuries. Despite the brake and the capture, the flying chain can whip along the unpredictable trajectory, and this is extremely dangerous.

The stretch is necessarily checked before starting work. During operation, a critical weakening can be determined by two signs:
