Installing and choosing the right chain for your chainsaw

Modern types of chainsaws allow owners to do the work without any special effort. The work will be performed with high quality and in the shortest possible time, if the installation of the chain on the chainsaw is made on time and in full.

Chainsaw is used to cut wood.

Why chain for chainsaws?

The range of cutting tools is huge, so you need to get the best copies for comfortable work.

The chiansaw is applied in construction, when harvesting wood, for improvement of seasonal dachas and adjacent territories. This is a universal chain tool that works with a two-phase motor. Its cutting part is represented by a chain connected in a ring. Often, to create a rounded shape, it is made up of links that have different shapes. The chain is attached to the metal bar. Most models have a sprocket. The chain is part of the component parts for non-professional and special saws.

Chainsaw Chains

Professional chainsaws for sawing wood are completed with chains with a step of 3/8 and 0.404 inches.

For amateur tools, chains having a pitch of 0.325 inches are used. The dimensions of the unprofessional caterpillar reduce vibration, but at the same time reduce the power of the tool.

High-quality devices for sawing wooden materials are completed with chains having a pitch of 3/8 and 0.404 inches.

Since the caterpillar is the cutting part of a chainsaw, its choice and installation must be approached with all responsibility.

Recommendations for choosing the cutting part of the tool

Before buying an important element, it is necessary to examine the main indicators characterizing it as an integral part of the cutting tool:

  • groove thickness;
  • chain pitch;
  • total number of links.

Several main groups were formed, united with each other by parameters related to the pitch of the chain: caterpillars of 3/8 inch are mounted on low-power saws, the thickness of the groove is 1.3 mm. The number of links depends on the length of the tire: at a distance of 32 cm there are 52 links, for 40 cm there are 56 links. On saw models from 350 to 401 cm do not put the tire in 645 cm.

To choose the right track for other models, it is necessary to study the parameters of the previously operated circuit.

Original models are characterized by the highest performance. They are resistant to friction, operated under adverse climatic conditions. Saw chains for chainsaws of any brands contain 50 leading links, step 3/8, groove 1.3 mm. Sometimes chain selection involves the fulfillment of several conditions:

  • exact acquaintance with the instruction to the motor saw;
  • knowledge of the characteristics of the saw chain;
  • counting the number of teeth;
  • study of the magnitude of the step between several links.

The chain has 52 leading links, a groove of 1.3 mm for a 35 cm tire.

The 52 link power saw has a pitch of 38, a 1.3 mm groove for tires is 36 cm, and for 10 cm tires the tool contains 72 links.

There are 3 types of tracks for the Poulan chainsaw. The 35 cm tire is equipped with a 52 link chain. The other two groups contain 56 and 62 links.

Russian products work with tires of 40 cm (at a step of 38) and 57 main links of the chain.

For tools operated in extreme conditions, used tracks made of metal alloys, giving them special strength.

Chainsaw equipment with special track detail

Often, for the safe operation of the saw, it is only necessary to take care of the health of all the nodes of the mechanism. A correctly mounted caterpillar will prevent the possibility of injury, and its installation will not give the master any special problems.

When it comes to mounting the circuit, you should prepare the tool in advance for work:

  • mittens;
  • screwdrivers;
  • key combination.
Chain

The chain should be well ground, then work will be safe.

Work will be safe if the chain is sharply sharpened and tight. However, it is not enough just to set the chain correctly on the chainsaw; you should regularly monitor the working condition of the caterpillar.

At the beginning of work, the saw bar is inspected: it is fixed with the help of a cover on the clutch.

When replacing the chain with a key, unscrew the nuts securing the chain sprocket cover. It is impossible to simultaneously remove the tension of the chain braking device.

To dismantle move the brake stop to the side. Pay attention to the holes through which the tension of the chain.

From the left move the saw bar, touching the leading sprocket. Utmost attention is required from the worker: he ensures that the teeth of the upper part of the chain are turned to the sprocket. One part of the chain is attached to the driving part, and the shanks are fixed in the grooves of the tires.

The tension of the chain occurs as a result of adjustment by a screw attached to the surface of the clutch mechanism. After mounting the cover, tighten the nuts slightly. The saw bar is in the upper position and the nuts are permanently fastened. Check the free distance of the track on the tire. The drum should rotate very easily when the chain slides along the tire.

The installation of the chain involves checking its tension after each session of refueling the tool. A loose part slides off the surface of the tire and injures the worker.

Inspect the tension with his hands, protecting them with mittens. In addition, new circuits change their length during operation, so checking should be done very often.

Sometimes in the process of work there is an important detail: it is not possible to install the circuit without additional heating and corresponding to its deformation from the side of the lower part of the tire.

Crawler tension control

No working professional will disregard the chain tension in a chainsaw. Slightly pulling the caterpillar, he instantly assesses the amount of stretching of the chain. The sound appearing at the moment of impact may be deaf and short.

The caterpillar tension is carried out sequentially, performing several simple operations. Inspect the fuel valve. The worker needs to make sure that the fuel system is blocked. You can remove the spark plug wiring or open the decompression valve. Plug electric saws pull out of the socket. The chain is turned in the direction of its rotation during operation.

The position of the file when sharpening the chainsaw chain

Defects of the chain tension are visually noticeable: a lower caterpillar sag is formed. Control is carried out by adjusting the circuit at certain time intervals. In the upper part of the shank should be a constant stock, formed when the chain is pulled. With a very strong tension, the caterpillar barely turns and quickly stops its movement.

Circuit adjustment in operating position is not allowed. Such negligence leads to the deformation of the bobbin or the breakdown of the crankshaft.

The tension of the track when working is carried out without tools. The maximum cutting depth is 390 mm, the weight of the cutting equipment is 9.4 kg.

To extend the life of a chain, tension is produced only under favorable weather conditions.

Lubricate the track links can only be clean oil, protecting them from falling into the circuit of the earth and dirt.

With long-term load on the electric saw, you should use two chains, alternating their work.

Monitoring of the electric saw brake

For protection of the working person from damage by a chainsaw, a braking device serves. With its help, the tool stops operation until the tire hits the worker’s body.

The device is a typical chainsaw

The device is a typical chainsaw.

The chain termination depends on two conditions:

  • braking speed;
  • tool start time.

The saw is started using 2 methods: contact and inertial. To protect the operator from throwing chainsaws, the brake is equipped with a flap, which rests the working hand. Some saws have protective strips masking the cutting part of the tool.

Upgrading the cutting part of the saw with their own hands

To solve the problem of sharpening the chain, special tools are used. Work is carried out on the basis of the configuration of the tooth. At one of the cutting edges, the upper part is slightly bevelled at an angle, therefore, in the process of intensive work, the operator should carry out 2-3 sharpening tools.

The interaction of the cutting edge with the ground tupit her, and chips change their size. Saw in the course of work slides on the surface of the tree. The main sign of a blunt tool is the enhancement of the moment of feeding and the formation of small chips. When working with a blunt instrument, the operator quickly gets tired, and the result of labor does not change for the better.

To work on the sharpening teeth prepare the tool:

  • the file is flat;
  • template;
  • sawdust hook;
  • tool holder.

Considering the contours of the tooth surface and the composition of the metal of chain links, a round file is used for sharpening. The main condition for obtaining a good result is the correct location of the file when grinding a tooth. The upper part of it is lifted above the edge of the tooth by 20% of the diameter of the tool. Keep the file at an angle of 90 ° vertically and at 30 ° horizontally.

The holder is attached to the tooth, and the tool touches it tightly, allowing the file to be positioned at the height required for the job.

Before you start, you must fix the tire. The first movements of the file should be smooth, soft, with regular tool turns. The teeth are first updated in one direction, and then the opposite elements should be sharpened.

It is necessary to evenly distribute the pressure on the teeth and make the same number of movements with a file.

The template protects the depth limiter from grinding, which is placed in the slot when applying an additional element. It is not allowed to replace the links during operation, otherwise there may be a disturbance in the functioning of the saw. The use of special kits allows you to make the correct sharpening tool with a uniform processing of the edges of the tooth.

The general scheme of the operation consists of several points:

  • fixing the chain brake;
  • mounting tool pattern;
  • designation of the first tooth;
  • direct execution of the process.

Proper installation of the chain on a tool for cutting wood will prevent technological losses, make the entire workflow safe, and allow you to cut wood for any purpose without any problems.
