Chainsaw chain tension adjustment

Any experienced logger who knows his business well, before starting work, be sure to check the chain tension and the degree of sharpening of the chainsaw teeth. If you do not pay attention to the state of the tool, its performance in the process of work is greatly reduced.

Chainsaw Chain

Correct adjustment of the chain tension of the chainsaw will extend its service life and will not allow it to slip off the tire during cutting.

Tension chain plays a crucial role in the performance of chainsaws. If it is not tight, it can easily be damaged or slip off the tire during cutting. On the contrary, if the chain is very tight, the pressure on the tool motor rises. This significantly reduces the life of the chainsaw, as it starts to wear out much faster. Chainsaw chain has another important purpose: it restrains the tire, which in the idle state goes in different directions.

How is the stretching procedure?

To check the degree of tension of the chain, it is necessary to pull it upwards, taking the tooth in the middle or extreme part of the outer side of the tire. If the tension is set correctly, 1/3 of the tail will be in the groove of the tire of the chainsaw. Exceeding this limit means that the chain is too tight, and the decrease is too weak. The free movement of the chain on the tire is important. It's easy to check by trying to twist it with your hand.

Chain direction

The direction of movement of the chain.

The process of tension is not laborious, you just need to understand the order of all necessary actions and pay due attention to this procedure.

Before starting to work, you must make sure that the saw does not work and its accidental start is completely excluded. Wearing protective gloves, you need to rotate the chain movement of the hand on its axis. In the case of a strong weakening in the back of the tire, a large sag will appear. It is this factor that is worth being guided by, checking whether the chainsaw needs adjustment before starting work.

First of all, you will need to inspect the tensioning mechanism located to the right under the side cover fixing the tool axis. Most often, this mechanism is the simplest bolt, but in some cases, chainsaws are equipped with a special tensioning system, where no additional devices are required.

After that, you need to slightly unwind the hardware located on the side and designed to fix the tire. Further, with a screw for adjustment, it is necessary to select the desired tension by moving the axis forward. To control the smooth movement of the chain, it will often be necessary to rotate it in the direction in which it moves during operation.

Having adjusted the chain with the help of a tensioning mechanism, it is necessary to fasten the hardware of the tire securely. If the setting was done correctly, the movement of the chain will be smooth. It should not jam and have a certain inertial reserve. If the adjustment is incorrect, the chain will stop abruptly, and it will sometimes jam. It should be borne in mind that this happens in case of a strong stretch. Since this has more negative effects on the instrument, it is better to always adjust the circuit with a slight attenuation. To extend the life of the chainsaw, it is recommended that this setting be carried out as often as possible.

Remember that it is unacceptable to adjust the stretch on a heated instrument.

After cooling, the chain is compressed, so if it is tight, it can pull the tire and deform it, which will lead to irreversible damage to the tool. Before adjusting the chainsaw, it is imperative that you cool it down.

Diagnosis and proper care of the chainsaw chain

The productivity of the chainsaw depends on a number of factors:

  • correct operation of the instrument;
  • chain tension adjustment;
  • timely sharpening teeth.

If the degree of stretching affects the performance of the chainsaw, then sharpening its teeth - at the speed of sawing. Therefore, it is extremely important to pay special attention to this moment. With a good sharpening of teeth, the cut is performed much more efficiently, more accurately and safer.

The regularity of the sharpening procedure does not have special standards, but professional fellers recommend performing it several times a day. This is due to the rather rapid blunting of the teeth in the process of intensive cutting.

Most often, the degree of dullness of the chain is determined with reference to the performance of the chainsaw. In addition, the tool needs to be sharpened when the tire starts to move to the side. Another measure of blunting is chip condition. As a rule, chips from properly sharpened teeth can be homogeneous. At the same time sawdust are rectangular or square. In the case of a blunted chain, dust will prevail in the chip, and sawdust will resemble the shape of a needle from a simple hacksaw.

If you regularly monitor the degree of tension of the chain and sharpen it in time, the chainsaw will last for a long time. At the same time the process of sawing even very hard wood does not give you trouble.

In case of insufficient experience, it is recommended to contact a specialist. Professional loggers determine the condition of the chainsaw and its components at the very first inspection. They will determine the degree of wear, the chain tension is too tight, and the sharpness of the teeth.

The latest models of chainsaws are equipped with a chain tensioner. But they also need special care, otherwise they will have to repair the instrument more often than they would like.
