How to install a chain on a chainsaw

The chainsaw chain is the element that is subjected to the greatest stress and overheating. From such influences, it can tear, fly off the guide rail, or simply become dull from prolonged use. For timely maintenance or replacement with a new one, you need to know how to independently remove the saw chain from the chainsaw and install it back. The step-by-step algorithm of these operations will be shown below.

Rules for replacing and tensioning the chain on a chainsaw

Chain tension on a chainsaw affects not only the normal operation of the machine, but also the safety of the operator working with it. Chainsaw . a very traumatic tool, and a loose saw chain can have dire consequences. In turn, the overstretched chain increases the load on the tool. Therefore, before each start of the machine, you need to make sure that this fundamental element has the correct tension.

How to connect the links

Some craftsmen recommend connecting the links by welding. This method is suitable if the rivets have been sawn off. But first you need to experiment on some piece of iron in order to select the appropriate welding mode.

Welding should be carried out with a small and narrow electrode. A rivet is welded to the link from the side and excess metal is removed with a file. The only drawback of this method. 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.

Chain direction and which side to wear

A chainsaw chain, if you look closely, has saw teeth pointing in one direction. Therefore, it is very easy to determine the correct direction of the saw teeth on the guide bar: if you place the chainsaw itself in the plane in which it is in the process of operation, then the row of teeth located on top of the guide bar should be directed towards the end of the bar with sharp edges. While, the row of teeth, which is located at the bottom of the chainsaw, with sharp edges should look in the opposite direction, towards the drive sprocket.

Putting the chain teeth inward to the grooves in the guide bar will not work, it simply will not stay on the bar. Therefore, it is necessary to put the chainsaw chain on the bar so that the guide lugs of the saw blade links are directed inside the guide bar.

Chain tension

The chain of the chainsaw, together with the guide bar, experiences the greatest loads during operation, unlike other parts of the chainsaw. Over time, it lengthens in size due to the boring of gaps in the connecting links. This process occurs with absolutely any type of chain, therefore, when operating a chainsaw, it is necessary to periodically monitor the correct chain tension and wear.

Depending on the state of the circuit:

• the duration of her life;
• safety of work on the felling of the forest or the dissolution of wood;
• ICE resource.

If the chain is overtightened, then the efficiency of sawing operations decreases, the motor and transmission are subjected to increased loads. The guide bar becomes very hot due to increased friction, the operation mode of the chainsaw goes into overspending of the fuel mixture.

Chain selection

The efficiency of the Husqvarna chainsaw and its service life depend not only on the ability to pull the links, but also on whether it is suitable for a particular brand of device. This detail differs according to several criteria:

• step;
• thickness;
• cutting depth;
• chain length and number of teeth.

The pitch value is the main parameter for the chain, on the basis of which this part is selected. Its value is determined by the gap between the tails. Common options: 0.325, 0.375, 0.404 inches. You can find out which type a particular saw needs by reading the instructions. The smaller the step, the less power the mechanism should have on which it should be pulled.

A large step affects the “aggressiveness” of the tool, that is, the cutting links enter the wood more strongly, and therefore the worker is required to hold the Druzhba chainsaw more tightly. The 0.325 chain is very common among household and semi-professional mechanisms. It can be pulled on Druzhba chainsaws with a power equal to 3 hp. For sawing small trees and construction work, this chain is best suited.

The designation of the number 0.375 is rare, since the marking has been replaced by the value 3/8 for the convenience of buyers, because 75 and 25 are easy to confuse if the purchase is made by a non-professional. The power of the Goodluck chainsaw, for example, should be 4 hp. Otherwise, the instrument may be damaged.

Links with a pitch of 0.404 can only be pulled on professional mechanisms with a power of more than 5 hp.

So, the main markings:

• 0,325;
• 0,375;
• 0,404;

What to do if the chain sags

If the chain sags, there is a risk of injury to the operator - after all, the saw blade can break or simply fly off the guide sprockets. Of course, modern chainsaws have safety and emergency stop systems, but these systems do not always work correctly.

It is important not to install a chain with defective or damaged saw links on a chainsaw, in addition to the danger of breaking at any time, such a chain will sharpen the guide grooves of the bar, which will lead to its distortion, uneven cut and failure of the guide bar.

Because of what the chain can sag during even a short operation?

1. There may be problems with the guide bar. Sometimes, due to an oversight by the operator or due to severe wear of the threads of the fixing bolts in the place where the guide bar is attached, vibration can occur, which causes the chain to loosen. It is necessary to check the condition of the fixing bolts and, if necessary, replace them with new ones. When the bolts are sufficiently tightened, these problems do not arise.
2. With sufficiently careful handling of the chainsaw, over time, any chain can wear out. Trying to repair it or assemble one from several is a futile exercise. If the chain set has stretched due to natural causes, then it would be best to purchase a new one.
3. The asterisk is skewed. Sagging can occur due to misalignment of the sprocket teeth. In this case, it would be best to contact a service center to repair and adjust the position of the leading star. Fixing the drive sprocket in the correct position is quite difficult, because you have to dismantle a lot of small parts, remove the guide bar, and then reassemble everything in reverse order.

Compliance with the instructions is the basis of the long-term operation of the mechanism

An instruction manual is attached to any tool, especially to such a complex one as a chainsaw

Stihl 180. Before the first start, you need to study the technical management. This is all the more true if you already have experience with the Friendship saw. Other assembly, chain tension, reference conditions and tool adjustment require preparatory knowledge. There are messages on the forums that the sawer poured out a candle at the first start, pulled the starter a couple of times, you must:

• Move the lever to the last position;
• Slowly pull the starter twice;
• Pull a couple of times sharply and rapidly.

To avoid problems, gasoline must be worked out to the end, without leaving the tank to sour for a certain number of days.

The operating instructions give a verbal definition of the markings on the tool body. There is also a description of the parts, the procedure for disassembling the Stihl 100 eighty chainsaw to replace the nodes, sharpen the chain.

Warnings about how to work with inventory of an overestimated threat, about non-dangerous techniques will help to avoid injury. In principle, when replacing the chain, be sure to check whether it is recommended by the manufacturer. Non-compliance of the units can lead to breakage, non-compliance with the warranty service criteria.

Recommendations for the correct operation of the chain sprocket

In the process of using a chainsaw, it is often necessary to inspect the wear (running in) of the sprocket. If the running-in depth exceeds 0.5 mm, the part must be changed. Working with inventory with a worn sprocket will result in faster chain wear. Chainsaw manufacturer Stihl recommends replacing the sprocket after 2 chains are worn out. It is also recommended to use not one chain, but alternately two or three. The load on the driven sprocket can be reduced through the use of a high quality chain and the measured operation of the lubrication mechanism. For high quality lubrication of your saw chain, use Stihl's unique guides and lubricants.

Step by step installation algorithm

Not all modern chainsaws are equipped with an adjusting wheel, which greatly simplifies the installation of the saw blade. Systems with a setting wheel among household chainsaws are generally rare. Therefore, it is very important to know the technology and sequence of installing the chain on a chainsaw.

Key points to pay attention to:

1. Prepare a flat surface on which you will put the chain and bar together. This will minimize the chance of chainsaw damage or loss of small parts. A tire is laid out on the prepared surface and a chain parallel to it.
2. Remove the sprocket guard, on modern chainsaws it is enough to unscrew the wing nut, on older models you may need a ring wrench of the appropriate size.
3. At the base of the guide bar, turn the tension sprocket all the way to the right. Only in this position is the chain installed.
4. Then the chain is sequentially placed link by link on the locking groove on the guide bar. Install the chain from the top of the guide, gradually turn it so that the bar is always on top and the chain on the bottom, this will always keep it taut and lie in the guide groove without problems. When doing this step, be sure to wear thick protective gloves, because your fingers will touch the cutting edge. When viewed from above, the cutter is always positioned forward towards the end of the guide bar.
5. Put both the bar and chain on the drive sprocket.
6. Fasten the chain sprocket cover in place. Make sure all mounting pins line up with the holes. Incorrect installation with distortions or not completely can cause extraneous noise, rattling.
7. Make sure that the guides "go" into the special mounting chute.
8. After installation, check the fixation of the chain on the chainsaw and on the bar. Everything must be securely fastened without backlash.

How to untangle a chainsaw chain

When removing an old chain or putting a new chain on a chainsaw guide bar, it can become tangled. It can also happen with careless transportation. When the chain is tangled, it coils into rings.

Due to the lack of flexibility in the transverse direction, it is very difficult to untangle with bare hands, because when you try to untangle one ring in another place, a new ring is formed.

It is necessary to put the chainsaw chain on a horizontal surface and unwind the rings in different directions, while pulling the blade in such a direction that the diameter of the rings increases. Sooner or later the chain will unravel into its natural position.

There is another way - you can rivet one link of the chain and straighten it, then connect it into a ring and rivet the riveted links back.

The main problems of the chainsaw chain

Chainsaw users often face the problem of saw chain tension. It either spontaneously weakens, or stretches and flies. Usually, the cause of these problems is the breakdown of the unit. Therefore, before proceeding with the chain link tensioning procedure, you should check and remove possible causes that could lead to incorrect adjustment.

READ How to Properly Sawing an Oval Shape

Chainsaw chain stretch can be caused by heavy loads or insufficient lubrication of the bar. This causes the saw to overheat, the metal expands, the saw element becomes larger and falls off the bar. The oil flow can be interrupted if the pump fails, the channels are clogged, the oil hose breaks.

If you changed the chain on the chainsaw to the newest one, then be prepared for the fact that during the break-in period it will stretch slightly. It is only necessary to check the tension just right so that the element does not fly off the tire.

When either the driven sprocket or the drive sprocket wears out, the chain link engagement is miniaturized, causing the saw blade to fly off. In this case, you will have to unscrew the chain drive and change the sprocket. Also, the saw blade of the unit may fly off due to its stretching or deformation of the tire.

If the chain on your chainsaw is loose, a faulty tensioner may be causing this problem.

Why does the chain jump off

Many, even the most experienced chainsaw users, have encountered a situation in their lives when the chain jumped off the guide bar during operation. The most common cause is insufficient chain tension or chain wear.

In 80% of cases, the stretched chain links slip off the teeth of the drive sprocket, and it flies out of the guide under the action of centrifugal force. Although sometimes the problem appears due to the incorrect position of the sprocket relative to the axis of rotation or a loose saw bar on the chainsaw.

Conclusion

Now on sale there are many models of chains for chainsaws. First you need to know what size is right for your chainsaw and not make a mistake in buying. The second step is to properly install it on the chainsaw. This is a somewhat time-consuming process, but if you know how to put on and set up the chain on the saw bar yourself, then the cheerful owner should not have any problems. We tried to describe in detail the process of installing a saw blade on a chainsaw.

We hope that after reading this article you will succeed the first time. But in order to minimize the appearance of problems with the chainsaw and chain in the future, do not forget 3 basic rules:

1. If the chain is worn and sagging, replace it with a new one;
2. If vibration appears during sawing and the cut is poor, watch the chain tension on the chainsaw;
3. Never use saw blades that are defective or repaired by dubious experts, your health and those around you are much more important than a small savings on buying a new and reliable chain.

In some situations, owners of chainsaws may experience some confusion in understanding all the chain marking designations for these tools. As a result, this leads to bad purchases. The choice of chainsaw is often determined by only a few basic aspects, one of which is chain pitch. This indicator helps to highlight the future capabilities of the tool, in particular its cutting speed, and according to the standards, it must also correspond to the level of motor power. How labeled are the chains? Let's try to figure it out!

Step is the intermediate distance between 3 rivets that are placed side by side. For the correct calculation of the chain pitch, it is necessary to freeze the distance between the axes of three rivets placed nearby. In formula form, this is:

Where, L is the step length, which in chainsaws characterizes the degree of distance of 2 teeth in relation to each other;

S - the value of the gap between the last 2 of the three rivets.

The step size a may also be equal to the length of the distance between 2 adjacent shanks.

Regularity: the simpler the distance between the cutting teeth, the deeper they will go into the material being cut

By increasing the chain pitch size, it becomes possible to increase the performance of the chainsaw. But, in a similar case, the degree of effort applied to implement the rotation of the drive sprocket changes. The higher the chain pitch, the more suitable the power of the engines and not just the physical forces expended for its pulling when sawing materials.

Taking into account the step size, today the chains are divided into several subtypes:

How to put on a chain on a chainsaw?

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

1. Loosen the screws securing the sprocket cover, usually it is tightened with a wing nut.
2. Turn tensioning sprocket to the right as far as it will go.
3. Put the links on the headset, starting from the top. Get drunk so that they fall into the appropriate grooves.
4. Reattach the chain sprocket mount, tighten the nut. The guides must fall into a special groove.
5. Release the chain brake, pull the chain along the line of travel to check the tension. Tighten the tensioner lever if necessary. Figure 4 - Installing the chain on a chainsaw

The setting wheel should turn freely after installing the chainsaw chain. At the end of work, be sure to lubricate all moving parts of the tool to avoid rapid wear.

Important ! The installation of the headset should be carried out only in tight protective gloves. This will protect you from injury and cuts from the sharp edges of the cutting edge of the teeth.

How to install a chainsaw bar on a chainsaw?

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

Popularly referred to as the "motor 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 protective covers, unscrew the fixing bolts by a third of the length and put the headset on. Then tightly tighten all the nuts, turn the tensioner with a special lever.

Installing a tire on Stihl and Husqvarna

Models of chainsaws from the manufacturer Stihl may differ during the assembly process. Walkthrough:

1. Open the wing nut, remove the protective cover of the chain sprocket. Turn it on the tire all the way to the right.
2. Place the chain on the bar, starting at the top, the cutting tooth on the top side should be pointing straight ahead.
3. Attach the assembled tire to the chainsaw, pull the structure onto the sprocket. Slide the guide over the collared bolt. Close the cover by inserting the pins into the holes provided by the manufacturer.
4. Turn the wing nut until the sprocket cover contacts the motor housing.
5. Turn the clamping bolt forward, the drive links should fall into the grooves of the bar. Fully tighten the wing nut.

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

The installation algorithm for a bar with a chain for Husqvarna saws is almost identical. The main difference is that in most models, the tension and adjustment of the location of the headset to the body is controlled not by one, but by two wing nuts. It is rare to find a separate adjustment lever on the outer sprocket guard, so tension adjustment should only be done with bolts.

Important ! Before starting to work with a chainsaw, you should carefully study the user manual. It describes in detail all the stages of setting up and assembling the tool.

Chainsaw adjustment on Husqvarna, Makita, Partner brand chainsaws

Below are videos on how to adjust the tension of the cutting headset on chainsaws from different manufacturers.

• Husqvarna chainsaw manual

• Instructions for chainsaws Partner

• Headset tension adjustment algorithm for Carver chainsaw

As you can see, the principle of adjustment for chainsaws of different brands is almost the same. The most important thing is to follow the setup procedure correctly so that the cutting attachment does not sag or be overtightened.

Chain tension

To check the tension, you first need to release the brake. Then pull the chain in the middle part of the headset; normally, the shanks should not go out more than 2/3 of the height. It is recommended to scroll it by hand - jamming and too fast sliding are not allowed. If necessary, tighten the nut on the protective cover.

Figure 5 - Checking the chain tension

Setting and checking the chain tension on the bar is an important process in the operation of any chainsaw. The work is easy to do on your own. Regular care of the tool helps to avoid injuries and loss of productivity, even when working with dense woods.

When to tighten the chain

You can determine that you need to tighten the main part of the chainsaw by its appearance. At the bottom it hangs freely, and at the top it can become tilted to the side. If you continue to work with such a canvas, it begins to wear out unevenly, gives an uneven cut, and may tear during operation.

Chainsaw chain tensioning algorithm

To adjust the shape of the canvas, stretch the chain. The procedure is possible in several ways, fast and more complex. To make this easier, you need to move the tightening bolt clockwise until the slack in the chain is eliminated. A more complex method takes more time:

1. Find the place where the tire is attached to the body.
2. Unscrew the nuts, loosen the links by pulling the top edge.
3. Using the chain tensioner on the chainsaw, you need to tighten it to the desired level.
4. Check tension.
5. Fix the tire.

To replace the chain with a new one, the tool is placed on a table or workbench. Next, unscrew the tire, remove the old canvas, clean the base. The new design is placed so that the links go in the opposite direction from the body. Then, using the tightening wrench, you need to tighten it to the desired level.

Checking and adjusting the mechanism should be carried out when the structure is cold. If you try to tighten after work, the sprocket is deformed or other elements of the system fail.

Ways to check the degree of tension

After installing the chain or already during sawing, the master should periodically check how the chain is tensioned. There are several ways to do this. You need to try to manually move the links in a circle. They should move in both directions without effort or with little resistance, but without signs of jamming, extraneous sounds. If the canvas sticks, makes a creak, a friction sound, it can be judged that it is too tight or not working.

The second way to check the degree of tension of the chain - after adjusting in the middle of the bar, pull the link up. It should be pulled up, but go out of the groove where it is installed in the gutter, no more than 2/3 (3-4 mm). The bottom of the canvas should not sag.

If the tensioned chain has passed the test on all counts, you need to start the engine, let the saw run at idle. Then turn off the saw and check the tension again. In the absence of sagging or jamming, the tool can be used for its intended purpose.

When to shorten or stretch the chain

If, after checking, it is found that the element is so slack that the adjusting screw does not help return it to normal, the only way to correct the situation is to shorten the chain. The specialist removes several links, no more than 2, until he reaches the desired length.

The chain wears evenly, so if you change old elements to new ones at the break point, this does not guarantee uninterrupted operation. The canvas may break at another weak point.

Stretching the chain, that is, adding new links to it, may be necessary if it is torn and some of the elements are lost. You can buy elements in the store or using a donor, an old chain. It is important to ensure that it is similar in thickness, link pitch and shape.

It is not necessary to contact a specialized service for this purpose. At home, you can also build up or shorten, if you have the appropriate equipment. For work, you need a riveting and riveting machine, spare links, rivets.

There are many reasons for chain stretching on a chainsaw, from breakdown of other elements of the system to violation of operating rules. In order not to bring the condition of the mechanism to a critical one, when expensive repairs are required, it is important to periodically check the degree of fit of the web and eliminate defects at the initial stage. You can build up or shorten the chain if necessary at home if you buy the appropriate equipment.

How to Change the Chain on a Stihl Chainsaw

The movement of the chainsaw in the tires is driven by a drive sprocket connected to the engine gearbox.

Wearing a sprocket on top of the sprocket means that it needs to be replaced as soon as possible, otherwise it will not engage with the chain and the chain itself will be damaged.

In this case, it should be borne in mind that the drive sprocket has a number of features, depending on the saw model and its type. In this article, we will tell you how to remove a star from a chainsaw.

Feature of saw structures

STIHL professional chainsaw

There are already several dozen chainsaws from different manufacturers, capacities and, most importantly, special applications. The saws are divided into:

• professional (for felling and construction);
• farm (garden).

Accordingly, the reason for the transfer will be different for them, as well as the sequence of actions. This is a feature of dust collectors. Thanks to most professional tools, the tire can change its position on the dust in two planes.

The main malfunctions of chainsaws and their elimination are described here.
