How to install a chain on a chainsaw

The size of the new chain depends on the length of the tire. Typically, tires last 2 times longer than chains, but provided that they are made of their quality materials. To clarify the desired length of the purchased chain for your tool, you need to measure the size of the tire. Typically, the length is indicated on the lateral part of the tire, but over time of operation, the entire marking is erased. You can find out the length of the tire by contacting the tool passport or measure it with a ruler.

Tire length measurement. How to measure correctly

If the decision is made to replace the tire along with the chain size larger, then this can be done in exceptional cases when the power of the chainsaw corresponds to. If you install on a household saw, set the tire is a size larger, then it will not cope with the assigned task by engine power. The passport for the tool indicates the installation of the tire of the corresponding length.

When you need to change the chain

The need to replace the chain mainly occurs with its wear and excessive stretching. If you can’t take a stretch of equipment using an adjusting screw, then it should be replaced. But installing a new part on an old, worn star and the same tire is not recommended, since this will lead to its rapid wear.

Many electric saw owners know that the circuit wear is 2-3 times faster than the production of the tire and sprocket resource, and resort to small cunning.

  • Having a new electric saw, you should buy 3 saw chains at once.
  • Having worked with one chain for several hours, it should be replaced with a new. Further, the second chain changes according to the same principle.
  • After each replacement of equipment, you need to turn the tire for uniform wear.

Performing these simple manipulations leads to uniform wear of all parts and extends their service life.

Strong wear of the saw canvas

The tire serves much longer than the chain. However, this does not mean that it can be exploited forever, and not think about replacing it. Usually the guide changes after 2-3 worn chains. Before replacing the guide chainsaw, you need to evaluate its technical condition. If the tire of Chinese.Made is installed on the chainsaw, then it can be worn out faster than the chain. That is why if the crooked cut of the wood of the chainsaw is detected, it is necessary to diagnose the tire.

To verify the wear of the tire, it is necessary to remove it and inspect it. Usually wear is manifested by a shortened one of the sides. Sometimes it is extremely extremely difficult to detect, so you need to use a caliper. The difference of several tenths of MM suggests that the tire needs to be replaced. There is still a simple way to check the deployment of the guide using a square. For this, the tire is located on a flat surface, and you need to put a square to the side. If the guide walls are in contact with the square from above and below, then the part is serviceable.

It is interesting! It is possible to increase the service life of the guide chainsaw only by periodic turning it. To do this, be sure to make sure that the tool provides such an opportunity, which will tell the appropriate markings on the headset about.

Accelerated tire wear can occur due to improper functioning of the oil pump. If the lubricant is served with large breaks, then friction increases accordingly, which means that the details wear out faster. If the lubricant works properly, then this increases the service life of not only the headset, but the entire tool.

Why the chain is stupid

There are several reasons why the chain is quickly blurred by inexperienced users. This is mainly due to the following reasons:

  • The use of low.Quality oil not recommended by the manufacturer;
  • Incorrect installation of parameters, the gap between the edge and the limiter should be 0.7 mm;
  • Lack of tool lubrication before work. Immediately before each use, lubricate the leading asterisk M8 oil.
  • There is no normal tension of the circuit, when installing it should be located exactly on the grooves located on the tire.

How to install a chain and a tire on a stihl chain

Innovative types of chainsaws enable their owners to perform work, without applying special efforts. The work will be done perfectly and in the shortest possible time, if you install the chain on the chainsaw in a timely and efficient.

Before proceeding with the assembly of the chainsaw, it is necessary to control the presence of all components. It is also important to observe safety precautions and certainly put on gloves to protect. This is a necessary condition for any contact with the saw chain, since there is a threat of injury to teeth of the chain.

Saws are with a fast tension device, a lateral tension device and a front chain tension device.

Following step.By.Step instructions, we prepare the saw for work.

Rapid tint device

To install the chain, you need to use the installation wheel. There is no need to use other tools.

  • Prepare the surface for work. It should be comfortable and even. In order not to spoil the surface and the tool itself, we cover it with something soft, for example, a rug. Now lay out the tire, circuit and motor unit on the surface separately.
  • The next step is to open the lamb nut, and then remove the lid of the chain star.
  • Turn the stretch sprocket mounted on the tire to the right until it stops.
  • Gradually lay the chain on top of the tire, starting from the top of the tire. It is important to monitor the correct direction of the chain. Do not forget about protective gloves.
  • Now the chain must be turned so that the tire is on top of the chain.
  • We re.Check the accuracy of the location and focus of the chain movement. A cutter located at the top of the bus should be facing forward.
  • We put on a chain in the assembly with a bus on an asterisk. In the process, the guide tire is approaching a bolt with a pile.
  • Now we put on the lid of the chain star on the motor block, while it is important to ensure that all the pins go into the corresponding holes. Turn the lamb nut to contact the chain sprocket with the engine body. The lid of the sprocket does not need to be delayed completely.
  • Next, in the direction of the top of the tire, we turn the clamping screw. Leading chain links should go into the tire groove.
  • We twist the lamb nut so that the chain star lid sits tightly on the motor block. Close the lamb nut until it is fixed.
  • We check visually so that the chain does not sag.
  • Next, check if we have a chain. To do this, let go of the chain brake, pull the chain with your hand along the line of movement (do not forget about protective gloves).
  • After that, the saw is ready for work and only the last step remains. The activation of the chain brake.

Thus, the installation of a saw chain and tires with a fast tension device has its obvious advantages, namely that it is not difficult to pull the chain and does not require an additional tool.

Side Circuit tension device

Consider the step.By.Step installation instructions for a lateral chain tension device.

  • As in the case of a quick tension device, the first step is the preparation of the working surface on which we lay out the block, the combined key, the tire and chain.
  • We bring the motor unit to the position vertically and unscrew the nuts. Now you can remove the cover of the chain star.
  • Turn the tensioning device for the circuit to the left so that the tension element comes into contact with the deepening in the case.
  • Further, as when installing with a fast tension device, we carefully put the circuit on the tire. We begin the process from the top of the tire. It is important to monitor the correct direction of the chain. A prerequisite remains the presence of gloves to protect when working with sharp cuts of the chain.
  • Turn the chain so that the tire is completely on the chain.
  • We re.Check the accuracy of the location and focus of the chain movement. A cutter located at the top of the bus should be facing forward.
  • We put on a chain in the assembly with a bus on an asterisk. In the process, the guide tire is approaching a bolt with a pile.
  • We put the lid on the motor block and tighten the nuts. Now the chain with the bus is rigidly fixed and it is possible to adjust the chain tension.
  • If the chain is slightly stretched and sags, then its links will not be in the tire groove.
  • Next, we turn the clip screw of the chain to such an extent that the chain sags completely a bit, and the links are located in the tire groove.
  • Lift the top of the tire up and slightly fasten the screw. The links of the chain should fully enter the groove.
  • Combined key to tighten the nuts.
  • We re.Check the chain in the groove. And check that there is no sagging.
  • Next, check if we have a chain. To do this, let go of the chain brake, pull the chain along the line of movement (do not forget about protective gloves). If the chain does not move, then you need to unscrew the nuts again and repeat the above manipulations.
  • You can activate the chain brake and start the operation of the chainsaw.

The anterior chain tension device

Now let’s tell you how to install a chain in the presence of a front tension device.

How to Select the Right STIHL Chainsaw

  • Separate components of the chainsaw: engine block, circuit, tire, combined key are laid out on the surface covered with a soft rug.
  • As in the case of the side of the chain tensioning device, we bring the motor unit to the position vertically and unscrew the nuts. Now you can remove the cover of the chain star.
  • The device for tensioning the chain must be turned to the left in the way so that the clamping element moves back from the asterisk.
  • Next, we put on the chain on the tire, starting from the top of the tire.
  • We turn the chain so that the tire is completely located on top of it.
  • We check that the chain is located on the bus correctly. It should be located so that the teeth on the upper part of the tire are directed forward.
  • Next, take a chain and a tire, and put a chain on the asterisk, pushing the guide tire on the bolts with a bacter.
  • The lid of the star should be put back on the engine block and tighten the nuts by hand. Now the tire and the chain are fixed and the chain tension can be adjusted.
  • When turning the clamping screw to the right, chain links enter the tire groove.
  • Raise the top up, turn the clamping circuit screw a little more. As a result of this, the links should enter the groove.
  • Now it is necessary to tighten the nuts with a combined key.
  • Check the sagging of the chain and finding the chain in the groove.
  • Next, check if we have a chain. To do this, let go of the chain brake, pull the chain along the line of movement (do not forget about protective gloves). If the chain does not move, then you need to unscrew the nuts again and repeat the above manipulations.
  • Saw prepared for work. It remains only to activate the brake of the chain.

The reasons for the weakening of the chain on the chainsaw

The chain of gasoline saw may need for tension and adjustment for the following possible reasons:

Commissioning a new chainsaw. The just purchased tool is supplied, as a rule, with unidentified saw set. Respectively, after assembly, it is necessary to adjust the tension of the chain. Replacing the saw chain. Despite the fact that chains of a certain type of size go to a particular bus, their length varies. It is also convenient to have several sharpened circuits that change in the process during prolonged work, and they are also, as a rule, of different lengths. Accordingly, after each replacement, the tension adjustment is required. Sharpening of the chain. Can be performed in two ways. Right on the tire, or on a special machine. In the second case, the circuit is removed from the chainsaw, and after installing it, it may require a tightening. Mechanical loads. In the process of sawing the links of the chain is resisted by wood. Because of this, it stretches over time and begins to sag. Natural stretching. The chain of the chainsaw consists of numerous links interconnected. In the process of prolonged operation, natural wear of parts occurs, which leads to stretching the chain. Incorrect adjustment. If the chain is initially stretched incorrectly, then immediately after the first saw there will appear sagging, requiring elimination

Inquired or violation of operating rules. In the process of sawing wood, solid items (nails, wire, other metal inclusions) sometimes come across, it is possible to squeeze the tire in the cut, or the tool is used for other purposes

In all these cases, the chain experiences the loads from which it is stretched and begins to sag. Low quality of the chain. The less high.Quality circuit, the faster it stretches, and the more often it requires adjustment of the tension.

Work begins with weakening the tension of the saw chain. To do this, you need a slotted screwdriver, which should be turned on several full revolutions counterclockwise adjusting screw. Access to the latter is through a special hole in the clutch cover (a number of models on this cover contains a clutch clutch block (emergency brake).

Then we unscrew the two nuts from the bolts with an open or united key, which fix the lid and tire. Carefully remove the lid.

To shorten the chain, one cutting link should be removed from it. After the fulfillment of this condition, it can again be regulated by the existing tension mechanism.

The choice is visually made. Determine a tooth that is as stuck and deformed in the process (for example, “caught” a nail or hairpin). Then we clarify the step of the chain to be shortened. You can do this correctly in several ways:

  • On the nameplate fixed on the saw chain;
  • According to information on the box (if it is preserved);
  • We measure the roulette or caliper.

To enter the table, you will need to perform one of three measurements. They are absolutely equivalent. Therefore, choose anyone at your discretion:

Divide the resulting value (in millimeters) by 2. The private will indicate one step in your circuit in millimeters. By the table, transfer it to inches.

  • The second option provides for the measurement of the distance between the five rivets. The resulting value is required to be divided into 4;
  • The third option, between the family (divide by six).

How To Put A Chain On A Chainsaw Properly

The resulting value, most often, will not coincide with those that are affixed in the table. Therefore, choose a tabular value as close to the results of your measurement.

If you work with household chainsaws of any manufacturer, then, with a probability of 95%, you will receive one of two values: 8.25 mm, which corresponds to 0.325 ”, or 9.30 mm (3/8 “). This is the most common step for the saw chains of unprofessional chainsaw models.

It must be prepared in advance. To carry out repair work (if there is a similar possibility), it is recommended to purchase a repair kit. This decision will ensure the maximum quality of work. For this money, you get 30 new connecting links consisting of two parts: the main (with the pins of future rivets) and the response (with holes for them).

In the absence of the opportunity to buy a repair kit, you can use the links from the second.Hand chain and rivets made independently. With certain skills, their quality and durability will be comparable to factory analogues.

Some masters manage to re.Use rivets removed from a shortened circuit. However, in such cases, most often, the walls of the connecting links have to be made more subtle. Therefore, this option can be used for short.Term operation of the saw in extreme cases.

  • 6 rivets;
  • 2 shanks;
  • 1 cutting tooth (selected by you);
  • 1 Sprinkled depth limiter.
  • On the removed area, you will need to cut 1 and 6 rivets (preferably on both sides).
  • The procedure guaranteeing the minimum probability of damage to the disconnected links is to steal the head of the riveting with a file (file);
  • You can cut it off using a hammer, a chisel (a chain is pre.Fixed in a grip);
  • Use a special nozzle for an electric drill, an angle grinding machine (corner grinder), an emery circle.

The use of mechanisms will allow this to do this much faster. However, such a solution has two significant deficiencies.

Firstly, the metal, with such processing, is significantly heated, which reduces its strength characteristics (the probability of a chain is being torn over one of the two remaining links in contact from 1 or 6 rivets).

After removing the external protrusions, the rivet is knocked out of the landing hole using a beard. It is recommended to slightly bend the side sides of the link.

If you need to shorten the original chain of the desired brand, no questions arise. And if you shorten and install a chain for a saw of a different model, you need to take into account the following.

It is necessary to pre.Calculate the number of remaining links in such a way that the number of guide protrusions located on the inside of the saw chain is combined with the size of the leading jelly of the saw.

To remove the rivets used to connect the elements of the chain, a pier is used, representing a small mechanical press of small sizes. The main elements of the design of this machine for the creep are:

Inside is the eccentric mechanism driven by the handle, which can be installed on the right or left on the case. In its original position, it is located in the extreme upper position (perpendicular to the supporting surface). Has a special limiter that allows it to deviate from the horizontal no more than 95%.

The piston rod is connected to the patching holder with an eccentric. Moving down, it easily squeezes the rivet without damaging the walls of the link.

Be sure to make sure that the machine has a punch of different sizes in the kit (rivets of various diameters are used to connect the structural elements of the saw chain, and each rod is designed only for one type).

When working, it should be monitored so that the diameter of the holes available in the sidewalls of the links coincides with a similar size of the punch.

When laying a disconnected circuit on the anvil, it is necessary to exclude the contact of its cutting part from the last. Only the shanks should contact her.

This question, with the apparent simplicity of the answer, can cause serious problems with the implementation. It is clear that riveting is required. But on free sale, even in specialized stores, they are rare quite rarely. If you’re lucky, you can find a repair kit, the links in which correspond to the size of the chain of your chainship (option, electric saw). But the chance to make such a purchase is small. Therefore, you have to consider alternative options for making rivets. There are not many of them:

Algorithm for mounting the cutting thread of the chainsaw

The leisurely installation of the chain takes no more than 30 minutes, provided that the correct and fixed installation of spare parts. The algorithm for installing the chain of the chainsaw consists of 8 steps:

  • It will be necessary to prepare a flat surface. This will avoid a curve of setting spare parts and the chain itself, and will also reduce the loss of fasteners to a minimum. First you need to lay out the tire and chain parallel to each other.
  • Remove the protection of the star. For old models, the fasteners of protecting the stars are made in the form of a lamb, which is not difficult to unscrew. For newer models of chainsaws, you need a wrench (most often by 10).
  • The drive asterisk of the chainsaw at the base of the guide tire must be unscated to the right to the right.
  • The links are applied to each fixing groove of the guide tires in a sequential order (link behind the link). The chain of the chainsaw is installed on top of the guide so that the tires are always on top, while the chain is from the bottom.
  • We install the tire and chain of the chainsaw on the leading star.
  • Set back the protective cover of the leading star. During the installation, it is important to make sure that the star itself stands smoothly and without a backlash.
  • We check the position of the guides that should be in special gutters.
  • We check how much the chain is fixed on the tire and in the chainsaw itself.

After the completion of this algorithm, the tension of the circuit itself remains. But before moving on to this procedure, you should make sure in the correct position of the chain. Otherwise, either you will have to repeat the algorithm again (up to the separation of the tire and chain).

The anterior chain tension device

Now let’s tell you how to install a chain in the presence of a front tension device.

  • Separate components of the chainsaw: engine block, circuit, tire, combined key are laid out on the surface covered with a soft rug.
  • As in the case of the side of the chain tensioning device, we bring the motor unit to the position vertically and unscrew the nuts. Now you can remove the cover of the chain star.
  • The device for tensioning the chain must be turned to the left in the way so that the clamping element moves back from the asterisk.
  • Next, we put on the chain on the tire, starting from the top of the tire.
  • We turn the chain so that the tire is completely located on top of it.
  • We check that the chain is located on the bus correctly. It should be located so that the teeth on the upper part of the tire are directed forward.
  • Next, take a chain and a tire, and put a chain on the asterisk, pushing the guide tire on the bolts with a bacter.
  • The lid of the star should be put back on the engine block and tighten the nuts by hand. Now the tire and the chain are fixed and the chain tension can be adjusted.
  • When turning the clamping screw to the right, chain links enter the tire groove.
  • Raise the top up, turn the clamping circuit screw a little more. As a result of this, the links should enter the groove.
  • Now it is necessary to tighten the nuts with a combined key.
  • Check the sagging of the chain and finding the chain in the groove.
  • Next, check if we have a chain. To do this, let go of the chain brake, pull the chain along the line of movement (do not forget about protective gloves). If the chain does not move, then you need to unscrew the nuts again and repeat the above manipulations.
  • Saw prepared for work. It remains only to activate the brake of the chain.

A timely and correctly installed chain at the saw will help make the process of cutting wood with a quick and safe.
