How To Tighten The Chain On A Stihl Chainsaw

For the frontal version, it is necessary to Unscrew the nuts and lift the edge of the chainsaw bar on which the chain is installed. The bolt in the case must be returned with a screwdriver to obtain the desired tension. Then the tire must be raised even higher and tighten the nuts back.
A quick version of the chain tensioning of the Stihl chainsaw assumes the following: the tension wheel located on top must be returned all the way to the right, after lifting the handle of the wing nut and loosening it. After the operation, the nut is tightened again and the handle is lowered. This concludes the procedure. Stihl chainsaw models have some differences in the rules of chain tension, it is advisable to find instructions for the tuned model.

How to tension the chain on a Stihl chainsaw

If a Stihl (Stihl) saw falls into your hands, do not be afraid and nervous, because got one of the most reliable and high-quality options Assembled from components created by one manufacturer at its own facilities.

Always wear protective gloves or gloves before tensioning the chain on a Stihl chainsaw or checking the tension. This not only protects your hands from cuts on sharp teeth, but also keeps them clean, since machine oil is difficult to wash and wash.

The main problems with the chainsaw chain

Chainsaw users are often faced with the problem of saw chain tension. It either weakens spontaneously, or stretches and flies off. As a rule, these troubles are caused by unit breakdowns. Therefore, before proceeding with the chain link tensioning procedure, you should check and eliminate Possible causes that can lead to a violation of the adjustment.

Chainsaw chain stretching can be caused by heavy loads or insufficient lubricant supply to the tire. Because of this, the saw overheats, the metal expands, the size of the integer increases, and it flies off the tire. Oil flow can be disrupted in case of pump breakdowns, clogged channels, breakage of the oil hose.

If you changed the chain on a chainsaw to a new one, then be prepared for the fact that during the running-in period it will stretch a little. It is only necessary to check the tension in time so that the element DOES NOT fall off the tire.

How To Tighten The Chain On A Stihl Chainsaw

When the driven or driving sprocket is worn, the effectiveness of the adhesion to the chain links decreases, as a result of which the saw element flies off. In this case, you will have to Unscrew the chain drive and change the sprocket. Also, the saw blade of the unit can come off due to its stretching or deformation of the tire.

If the chain on your chainsaw weakens, then a malfunctioning tensioning mechanism can cause this malfunction.

After you have worked with the chainsaw for a while, there will come a moment when the chain tension will loosen. This is due to its stretching and heating. Many do not know how to tighten the chain on a chainsaw, so they start looking for the answer in the instructions or on the Internet. Well, in this article you will learn how to do it correctly. The tension is approximately the same for any chainsaws: at least Stihl, at least Husqvarna, at least Champion, at least some other.

First of all, the Stihl chain tension is checked. If the chain sags (part of the internal teeth is visible), then tighten it. In a relaxed state, it will damage the tire surface and render dust unusable. If the chain is motionless when the brake is released, then it is overtightened, respectively, it must be loosened.

How to determine the degree of tension

A quick check of the chain tension is very simple: you need to grasp the prong and pull it up. If the chain is tensioned correctly, the tail will be immersed in the groove of the bar by 1/3 of its height. An excess of this indicator indicates excessive tension, and a decrease in the indicator indicates a weak.

With a strong tension on the cutting element of the chainsaw, the tire begins to heat up and grind, the load on the engine increases, and it wears out quickly. Do not switch on the machine with a loose chain, as it can be pinched and cut off when sawing, which poses a danger to the user of the machine. The chain can fly off the tire and injure limbs, and it often breaks itself and damages the tire. Also, work with a weakened chain element leads to one-sided wear of the tire, after which the device stops making even cuts, and the dust is taken away.

How to tension the chain on a Husqvarna chainsaw

All safety rules described for the model above are the same for Husqvarna (Husqvarna) saws. Do not tighten the chain when starting the saw motor. It is allowed to start work only after a complete stop and cooling.

Before tensioning the chain on a Husqvarna chainsaw, check if additional tension is required. It should be noted that new saw chains require more frequent tensioning. From time to time, it is stretched in the process of work, so it is necessary to carry out this operation before each of its implementation, if necessary. Otherwise, it will be necessary not only to replace the chain, but also the saw drive mechanisms.

First of all, it is necessary to loosen the fastening nuts located on the clutch cover. The next step is to return the adjusting screw 45 degrees. If the chain on your Husqvarna chainsaw is overtightened, turn to the left (counterclockwise). In the opposite case, the screw turns to the right. If a single tightening is not enough, the operation must be repeated. At the end of the procedure, tighten the nuts on the protective cap using a combination wrench. They can also check the chain tension of the chainsaw by hooking it onto the outer tooth and pulling the chain along the guide in the tire.

The chain tension on the chainsaw affects not only the normal operation of the machine, but also the safety of the operator working with it. A chainsaw is a very traumatic tool, and a weakening of the saw chain can lead to dire consequences. In turn, an overly tensioned chain increases the load on the tool. Therefore, before each start-up of the machine, you must make sure that this important element has the correct tension.

What turns on the chainsaw to tighten the chain?

In general, for all chainsaws, the procedure will look like this: loosens the fastening of the side cover and rotate the chain tensioner. But the cover mount and tensioner themselves may be different on different chainsaws.

The easiest option is a side cover attached with one or two nuts and a tensioner in the form of a screwdriver bolt (either slotted or Phillips). In this case, simply loosen the nuts and steep the bolt clockwise. The bolt can be located either on the side in the cover, or in the front. again in the side cover, or in the body of the chainsaw itself.

But there is also a keyless chain tension. this is when no keys or a screwdriver are required to loosen the side cover and turn the tensioner. In different manufacturers, these systems look different. Below you can see in the pictures what they are, and what turns.

The chain stretched

Any functional changes in the chain lead to a decrease in the productivity of the tool, injury during operation.

It should be regularly monitored so that there is no deformation of the metal and stretching of more than 1 cm.

If this problem still occurs, you need to purchase a new chain or correct the old one.

Disconnect the chain links on the machine or fix it in a vice, file off the rivets and knock them out with a bit (it is not recommended to use an angle grinder).

Remove 1-2 links depending on the chain stretch. After that, put all the elements in place, insert the rivet and beat it off with a hammer, use a special rivet tool. For reliability, it is recommended to use a welding machine. At the end of the work, grinds off excess and burrs with a thin file.

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

Often, problems in the operation of a chainsaw arise when the tire is incorrectly installed. This can be recognized by the characteristic rattling, vibration and low performance of the saw during operation. The tire is attached to the body between the outer plate, fixing is carried out with a special bolt.

Popularly referred to as the “engine assembly”, this part consists of a drive sprocket and locking bolts. It is not difficult to install the tire together with the saw. you need to remove all the protective covers, Unscrew the fixing bolts a third of the length and put the headset. Then tighten all the nuts tightly, turn the tensioner with a special lever.

How to properly put a chain on a chainsaw?

In most chainsaw models, the chain is easy to put on the bar by unscrewing the main screw, then the links need to be placed on the drive sprocket. Before starting work, the general condition of all cutting surfaces and the guide groove and setting wheel should be inspected. Often, dirt and small chips accumulate in it, which will subsequently lead to planned repairs, deterioration of sliding. Step-by-step algorithm of work:

Loosen the screws securing the sprocket protection cover, usually it is tightened with a wing nut.
Return the tensioning sprocket to the right until it stops.
Will overlay links to the headset, starting at the top. Drink so that they fall into the corresponding grooves.
Replace the chain sprocket mount, tighten the nut. Guides Must fall into a special chute.
Release the chain brake, pull the chain along the mowing line to check the tension. Tighten the tensioner lever if necessary. Figure 4. Installing the chain on the chainsaw

The setting wheel should rotate freely after installing the chainsaw chain. At the end of the work, it is imperative to lubricate all moving parts of the tool to avoid rapid wear.

Loose tire

When the chain tension is reduced, the problem is often accompanied by a weakening of the tire itself. To check its condition, you need to inspect the place between the top plate on the headset casing and the inner surface on the case. When the locking bolts are loosened, the bar begins to move, which can be seen by the characteristic vibration during sawing. With frequent use, it is recommended to regularly clamp the bolts.

Figure 1. tire weakened

If you decide to tighten the tire yourself, you need to find and lower the chain brake. Return the tensioning screw so that the chain fits snugly into the grooves. After that, pull back the chain in the direction of travel, if it is too tight, loosen the screw.

Trouble with a leading star

Sometimes chain slack is due to drive sprocket problems. The most common situation is when it is poorly secured. Step-by-step algorithm to Twist the asterisk:

Remove the engine cover.
Remove the air filter and Unscrew the candle, put in its place a special stopper to fix the piston in an immovable position.
Use the angle grinder wrench to rotate the clutch disc clockwise to the highest position. Check the tightness of the sprocket, adjust its position. Figure 3. the driving star on the chainsaw

After tightening, reassemble the chainsaw, be sure to put on the protective cover. When assembling, check that the chain fits snugly on the bar.

How to put a chain on a chainsaw correctly: instructions, recommendations, basic methods

The chain is an important structural element of a chainsaw. It is she who has the greatest load during work, so high-quality and systemic care is required. When using any model, it is important to know how to put on the chain correctly. Watch out for its tension. If it is not secured correctly, there is a risk of stretching and coming out of the grooves. Reduced saw performance and increased risk of injury at high power.

Fitting the tire on Stihl and Husqvarna

Chainsaw models from the manufacturer Stihl may differ during the assembly process. Step by step guide:

Open the wing nut, remove the chain sprocket cover. Return it on the tire all the way to the right.
Place the chain on the bar, starting from the top, the cutting tooth on the top side must point straight ahead.
Attach the assembled tire to the chainsaw, pull the structure over the sprocket. Slide the guide onto the shoulder bolt. Close the cover, hit the pins in the holes provided by the manufacturer.
Turn wing nut until sprocket cover is in contact with motor housing.
Clamp bolt back forward, drive links Must fit into bar grooves. Tightens the wing nut completely.

At the end of work, check the tension, if the headset does not move well, adjust the tension with a nut. Engage the chain brake before starting.

The Husqvarna saw chain installation algorithm is almost identical. The main difference is that in most models, the tension and adjustment of the position of the headset to the body is controlled not by one, but by two wing nuts. A separate adjustment lever is rarely found on the protective housing of the outer sprocket, therefore the tension should be adjusted only with bolts.

Why did the chain fly off?

There are several reasons why the circuit may collapse during operation. This may be due to improper tire operation or insufficient tire tension. The problem sometimes appears even with an insufficiently secured drive and driven sprocket. Determination of the cause allows you to accurately select the required repair, tools.

Chain tension

To check the tension, you must first release the brake. Then pull off the chain in the middle of the headset, normally the shanks should NOT extend more than 2/3 of the height. It is recommended to scroll it manually. it is not allowed to jam and slip too fast. If necessary, tighten the nut on the protective cap.

Figure 5. Checking the chain tension

Installing and checking the chain tension on the bar is an important process in the operation of any chainsaw. The work is easy to do yourself. Regular tool maintenance prevents injury and reduced productivity, even when working with dense woods.

If pulling doesn’t work

With the correct installation of the chain, there should be no sagging; when pulled, the teeth come out of the grooves no more than 4-6 mm. After work, it will scroll along the tire in the direction of rotation, the stroke should be smooth and easy. If the tension correction does not help, the cause of the under tension may be due to the following factors:

Incompatibility between the chain model (pitch of teeth, length, size) and the saw headset of your chainsaw model;
Failure of guide sprockets;
Breakage of the tensioner, adjusting screw;
Lack of lubrication (the problem is solved by the additional introduction of oil);
Mechanical damage to the bottom of the teeth, grooves in the headset.

Figure 4. Excessive stretching

If you cannot achieve sufficient chain tension, the tool must never be used. You should check the compatibility of all components, if possible, contact the service center to fix the breakdown. Using a chainsaw without a quality setting can lead to dangerous consequences.

Step by step instructions: how to properly tension the chain on a chainsaw?

Regardless of the class of the chainsaw, the chain is weakened under the influence of intense regular loads. This can be determined by the appearance of characteristic gaps in the link joints, a change in the sound of work and an increase in vibration. You can tighten the tension of the saw headset yourself using a special mechanism. This avoids serious damage and injury while working with wood.

Why chain tension is necessary?

The chain performs two functions at once. it directly cuts the wood and fixes the tire, preventing its arbitrary movement. The correct position and tension of the chainsaw chain allows you to fully operate the tool, avoid dangerous injuries during operation. If the saw head is installed incorrectly, it will easily fall off during sawing, injuring the operator. Even with a slight weakening, it gradually breaks the tire groove, which leads to the failure of the teeth of the driven sprocket.

In this case, excessive stress leads to an increase in the load on the rotor, a reduction in the saw’s service life. Therefore, it is important to regularly check the tension, if necessary, tighten the special mechanism on the tool body.

How to adjust the chain correctly?

You can install the chain and adjust its voltage with your own hands, without contacting a service center, regardless of the class of the chainsaw, its age. Before starting work, each link should be fully checked, as sagging can also be associated with wear on the teeth or sprockets. Step-by-step algorithm for the correct tension of Stihl 180, Husqvarna, Champion, Partner and other models:

Place the instrument on the table so that its headset is on top. Unscrew the threaded fasteners of the protective cover, dismantle the tire and thoroughly clean each element (it is convenient to use a vacuum cleaner or a compressed air cylinder)
Determine the correct position of the chain. Teeth Should be on top, going away from the body;
Put it directly on the tire. Secure the bolt mechanism, make sure there is sufficient free play.

Before looking for an answer to the question of how to pull the chain on a chainsaw, you should study what methods exist. There are two widespread methods of tension. fast and frontal. The first method involves the use of a tightening bolt. It must be tightened clockwise, at the end, be sure to check the wing nut and lower the handle.

Figure 3. A quick way to stretch

The frontal method is more complex, the main steps are:

Unscrew the nuts that secure the tire to the chainsaw. Loosen and slightly pull up on the edge of the headset;
Tighten the adjusting screw to the desired level, fix the tire back with the nuts;
Check the chain tension with your fingers, if necessary tighten the nut.

Regardless of the characteristics of the tensioner, the chain must not be overstressed. This is no less dangerous than loosening it. After installing and adjusting the gripping mechanism, it is recommended to start the tool at idle speed. Carefully check the smoothness of movement of the chain, the presence of slack and extraneous whistling sounds.

Tensioner mechanisms

Depending on the design features of the tool, the tensioning mechanism of the headset may differ.

In budget models of chainsaws, a classic bolt with a straight thread is used to adjust the chain, which is located on the side of the body.

In this version, the package includes a special tightening key or there is an external slot for a slotted screwdriver.

All professional models are equipped with more convenient adjusting mechanisms. With the help of them, you can tighten the chain with one movement of the lever or by turning a special disc. Their design consists of a built-in tensioner, locking when turning is achieved by means of a lock nut. In some models, the adjustment is carried out by locking the tire in a certain position of the tool cover. Regardless of the method, the circuit voltage needs to be corrected only in a cold state. Hot chain tension causes sagging during cooling.

How to check the correct tension?

To ventilate the quality of tension, you should gently pull it back in the middle of the tire.

The permissible level of exit of the tails of the cutting links should not be more than 2/3 of their length.

You can also determine the need for a tightening by the following criteria:

The appearance of a creak and gnash in the area of the main drive sprocket;
Loosening the tightening of the protective mechanism, tire fasteners;
Jamming when sawing, increased vibration and noise.

Chainsaws reduce productivity and increase operating time. Even when sawing soft woods, the chain starts to get stuck in the groove, the speed and smoothness of the movement are reduced.

Possible risks in case of uneven tension

Any changes to the saw head (sagging, broken teeth, overvoltage) can lead to problems during operation. Risks of sagging the tool:

Decrease in productivity when sawing, felling timber;
The chain gets stuck in the groove, flies off the tire during starting;
Breakage of the headset, damage to the guide sprockets;
High load on the rotor, reduced tool life;
Getting serious injuries while working.

Before starting work, it is important to qualitatively check all moving mechanisms, the tightening of the adjusting bolt. Use a special oil for lubricating the teeth, saw headset. Setting up the chain and cutting directly must be carried out in protective clothing, wear gloves and glasses to avoid injury.

The chainsaw headset is an important building block for productivity and quality. Before starting operation, check the tension, make sure it is correctly installed. Tension is adjusted using a special bolt or lever on the body. Sagging or excessive tension can lead to serious consequences. saw breakage, injuries while cutting wood.

Is it possible to shorten the chain yourself

In the case when the chainsaw chain has stretched so much that it is NOT stretched anymore, it becomes necessary to reduce its length.

The main problems with the chainsaw chain

If the chain on your chainsaw weakens, then a malfunctioning tensioning mechanism can cause this malfunction.

Rules for replacing and tightening chains on a chainsaw

How to determine the degree of tension

Tension algorithm

Before tensioning the chain on the chainsaw, you must turn off the engine of the unit, or disconnect it from the mains if it is an electric saw. Do not adjust or replace the gripping element if it is in the Heat condition. If this is done, then the metal will shrink after cooling and the tension will be too great, which can lead to increased stress on the engine and deformation of the tire.

The chain tensioner is located on the right side of the machine, under the cover, in the place where the clutch brake is installed and the bar mount is located. On Husqwarna, Stihl, Poulan and Partner chainsaws, the external tensioner looks like an ordinary bolt.

So, in order to adjust the chain element of the apparatus, you need to perform the following steps.

Loosen the nuts on the right cover slightly so that the tire is not skewed.
Insert a screwdriver into the tensioner adjusting bolt, start turning it to the right (clockwise). After THESE actions, the tire will start moving and the chain will be tensioned. If you rotate the bolt to the left (counterclockwise), the chain links will relax.
Next, you should tighten the chain to the state so that it does not sag and does not dangle.
Check the tension of the element: grasp the cutter link approximately in the center of the bar and pull it down with a slight force. The chain must be taut, have elasticity, and the shank of the cutting link must fit into the groove of the bar about 1/3 of its height.

On a Makita electric saw, the tension adjuster is designed in such a way that it can be turned without the use of any tools. Turning it clockwise will tighten the chain, if you turn the adjuster in the opposite direction, the tension of the chain element will loosen.

Chainsaw replacement

If you need to replace the chain on the chainsaw, then follow these steps.

Remove the cover covering the sprocket. To do this, most often it is necessary to Unscrew the fastening nuts.
Having unscrewed the fasteners, Remove the cover covering the coupling with an asterisk.
Grasping the tire with your hand, move it towards the sprocket so that the chain looses.
Remove the chain element from the drive sprocket.
Now you need to install the chain on the chainsaw. Take a new saw blade and put it on the drive sprocket first.
Then you need to put the chain on the tire, put the element in its groove around the entire perimeter. It is important that the links fit properly on the driven sprocket located on the top of the tire. Pay attention to the direction of the cutting links when installing. They must be oriented away from the unit, on the top of the tire.
Run the bar in the opposite direction to the motor to tighten the chain a little.
After laying the gripping element, before putting the cover back in place, it is necessary to align the screw, through which the tension is adjusted, with the adjuster located behind the tire. Only then can you put on the cover and screw the nuts slightly. Next, insert a screwdriver into the adjusting screw and make the final tension. How to properly tension the chain was described above.
Raise the tire slightly and tighten the nuts, thus securing it. It is important NOT to overdo it and NOT to strip the thread.

How to remove a rivet

To change the elements of the chain or shorten it, you will need to Disconnect the links as follows. Fix the chain element in a vise and grind off the rivets, namely their protruding parts. To do this, you can use a file or File. Make sure that the side portions of the link are not exposed to seam.

Using the beard (as it looks like, shown in the photo below), knock out the rivet.

There is another option for separating the links. To do this, you do not need to grind off the rivet heads. Place the link, namely its rivet, over some hole in the metal or over the slightly parted jaws of the vise. Next, you should put the locksmith barb on the rivet head and hit it several times with a hammer.

Continue knocking out both rivets alternately as they are firmly secured by the opposite side of the link. Gradually, the rivets will begin to come out of the top of the link, and it will come loose.

How to connect links

Some craftsmen advise to connect the links with a quarrel. This method will work if the rivets have been filed off. But first you need to experiment on some piece of iron in order to choose a suitable quarrel mode.

The quarrel must be carried out with a shortened and thin electrode. The rivet is welded to the side of the link and the excess metal is removed with a file. The only drawback of this method is overheating of the metal from which the circuit elements are made. As mentioned above, due to overheating, the wear resistance of the links may decrease.

Why the chain flies, we find out the reasons

If you wondered why the chain on your chainsaw flies, then there is some kind of malfunction in the mechanism. There are three main reasons for this problem: bar malfunction, chain stretch, and loose driven sprocket. Let’s take a closer look at each of the possible causes of breakdown.

Bus problems

When problems arise with the tire, the tension is almost always tenacious. Usually this problem occurs at the place where the tire is attached.

This place is located in the groove between the outer plate, which is located on the chain guard and the inner plate, which is located on the motor housing. The casing together with the tire is fixed with a bolt. Such an attachment is referred to as an “engine assembly”. Drive sprocket and tire mount protected by special covers.

If the fixing bolts are loosened, the tire starts to move or vibrate. If the tire is good, then the chain tension should be normal. After stretching, she will walk for at least five working days without suspenders. Therefore, you need to properly tighten the bolts that hold the tire.

To understand how to tighten the chain on a chainsaw, you first need to find and release the chain brake. The tension screw is next to the bar and is turned until the chain is NOT stretched over the bar. Then RETRACT the chain clockwise. If it does not move, then it needs to be slightly loosened, turned the tension screw in the opposite direction.

Tension check

To check the chain tension, the saw brake must be disengaged. Then manually pull the chain along the bus, if it runs smoothly and does NOT sag, then everything is fine. If the chain walks very tightly, then it needs to be slightly weakened, because there is a risk of breaking during work.

Chainsaw device features

The main part of a gasoline saw is the engine. In most modern devices, the engine is single-cylinder. Air cooling, two-stroke piston system. Oil in these types of engines is added directly to gasoline, and all due to the fact that the fuel is constantly flushing the crankcase. The oil-gasoline ratio varies from 1:20 to 1:50 depending on the manufacturer of the chainsaw.

The air filter on gasoline saws plays an equally important role. It needs regular cleaning. If the filter is heavily contaminated, dust from it will fall directly into the piston system, which will lead to engine damage.

If the filter is clogged, the saw will lose speed and the engine will overheat, which can burn the piston rings.

The starter on gasoline saws is a rope with a handle that you pull on to activate the motor. When you pull on the rope, the teeth catch the ratchet, the flywheel begins to unwind.

Many people complain about long pulling on the rope to ignite the engine. It depends on whether the carburetor is correctly aligned. If the carburetor produces the correct oil-gasoline mixture, then problems do not have to arise.

The main operating mechanism is a tire with a tenacious.

The chain consists of three types of teeth: leading, cutting and connecting. They are riveted together. Cutting teeth are located on two sides: right and left.

It is tenaciously divided into two types: high profile and low profile. The first type includes tenacious, in which the teeth are located with a large gap, to the second. with a smaller gap. Chains can also vary in shank thickness and link length. The chainsaw chain is attached to a bar that guides it in the right direction. The end of the tire has a specific groove that holds the links and allows the chain to rotate. A driven sprocket is located in the front of the tires. The chain together with the tire is called a headset, since they are detachable parts of the chainsaw.

The gasoline saw has an automatic chain lubrication system. The tire supplies oil, which is then absorbed by the sawdust. If the saw is idling, the oil supply stops.

The chain stretched

If you have a chain slack on a chainsaw, then this indicates a malfunction of some mechanism, one of the options is wear of the most tenacious.

Over time, the metal deforms and the chains become 0.5-1 cm longer. It is best to fix this problem by purchasing a new circuit, but there is a way to get the old one back. Experts say that it is very difficult and almost impossible, but we will tell you how it can be done at home.

For this we need:

Pressure;
File;
Electric welding machine (NOT needed in all cases);
A hammer;
Pliers;
Beard.

A regular chainsaw chain is made of strong steel, so it is difficult to disconnect. Disconnect the chain you need on the inside of the rivet, which serves as a connecting mechanism.

To begin with, the chains need to be fixed in a vice, and then gradually grind off the protruding part. You need to grind with a file or a file. It is not recommended to use an angle grinder, as there is a risk of damaging the lateral parts of the links. After sewing, the rivets are knocked out with a beard. A knocked-out rivet should not be thrown away. You may NOT be able to find a replacement. Manufacturers of gasoline dust do not produce SEPARATE parts for the chain, as they DO NOT assume that consumers will be able to repair the chain themselves. Most likely you will not be able to make a new rivet yourself, so you will have to install the old one.

In order to shorten the chain, you need to split it in two places. But remember that the number and spacing of the guide lugs on the inner side of the chain must match the drive sprocket.

After removing one or more of the links (depending on the degree of chain stretch), the chains can be connected. We connect to old rivets, while pressing them tightly on the sides.

Next, we need a welding machine. The rivet needs to be welded to the lateral parts of the link. After that, we grind off the excess with a file, which was formed when working with welding. The chain can be considered serviceable again.

How to tension: installing the chainsaw cutting element

We have analyzed the main reasons for the sagging chain. How to install a chain on a chainsaw is described in the paragraph above. Now you need to correctly tighten the chain, and check if it will overtighten.

Chain tension

There are two ways to stretch the chains: fast and frontal. The best way to stretch the front is.

If it carries out a frontal tension, then you need to unscrew the nuts that hold the tire, and lift it by the edge. With a special bolt in the case, you need to tighten the chains to obtain an acceptable tension, and then raise the tire even higher and clamp it.

If using the quick tightening method, first lift the wing nut handle and loosen it. Then the chain tensioning screw will be tightened clockwise until it stops. Then re-tighten the wing nut and lower the handle.

Installing the chain on a chainsaw, how to properly tension and check the tension

If you have a chainsaw at home, then you should know that it requires special care. It is necessary to periodically clean and sharpen the chains, clean the air filter, oil supply and tires. And, of course, you need to Watch the chain tension, since with a bad tension there is a line not only to harm the dust, but also to your health if the chains at high speeds fly off.

Poor drive sprocket

One potential chain slack on your device is a drive sprocket issue. Most often, everything happens due to the fact that the star is poorly fixed. Now we will tell you how to properly fasten the star and then put the chain on the chainsaw.

First you need to remove the engine protection cover. Next, remove the protective cover of the spark plug, pull out the air filter. Then with a special key you need to Unscrew the candle. A special stopper is placed in its place, which fixes the piston in a certain position. With a special wrench (you can use a universal wrench for an angle grinder), turn the clutch disc clockwise until the piston is in the uppermost position. If you look into the hole of the plug, then the piston should remain at the bottom. You can use a thick rope as a stopper; it is better to fold it several times. Once locked, you can clamp the drive sprocket by rotating the clutch disc counterclockwise.

After clamping, you need to do everything in the reverse order, that is, assemble the chainsaw. A chain is put on the tire, it must hit the drive sprocket that holds it. The tire is placed in special mounting holes and bolted. Then protection is put.
