How Should A Chain On A Chainsaw Stand?
Modern types of chainsaws allow owners to do the job without much effort. The work will be performed efficiently and in the shortest possible time if the chain is installed on the chainsaw on time and in full.
A chainsaw is used to cut wood.
Why do I need a chain for a chainsaw?
The range of cutting tools is huge, so you need to purchase the best copies for comfortable work.
A chainsaw is used in construction, in the harvesting of wood, for the improvement of summer cottages and surrounding 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 composed of units having different shapes. The chain is mounted on a metal bar. Most models have a sprocket. The chain is part of the component parts for non-professional and special saws.
Professional chainsaws for sawing wood are equipped with chains in increments of 3/8 and 0.404 inches.
For an amateur instrument, chains having a pitch of 0.325 inches are used. The dimensions of an unprofessional caterpillar reduce vibration, but at the same time reduce the power of the tool.
High-quality devices for sawing wooden materials are equipped with chains with a pitch of 3/8 and 0.404 inches.
Since the caterpillar is the cutting part of the chainsaw, it is necessary to approach its selection and installation with all responsibility.
Recommendations for choosing a cutting tool
Before buying an important element, it is necessary to study the main indicators characterizing it as an integral part of the cutting tool:
- groove thickness;
- chain pitch
- total number of links.
Several main groups have been formed, combined with each other by parameters related to the chain pitch: 3/8 inch tracks are mounted on low-power saws, the groove thickness is 1.3 mm. The number of links depends on the length of the tire: 52 links fall at a distance of 32 cm, 56 links per 40 cm. On saw models from 350 to 401 cm, they do not put a tire of 645 cm.
To select the right track for other models, it is necessary to study the parameters of a previously operated chain.
Original models are characterized by the highest productivity. They are resistant to the effects of friction, are operated in adverse climatic conditions. Saw chains for chainsaws of all brands contain 50 leading links, 3/8 pitch, 1.3 mm groove. Sometimes choosing a chain involves several conditions:
Chainsaw chain device.
- precise familiarization with the instructions for the motor saw;
- knowledge of the characteristics of the saw chain;
- counting the number of teeth;
- study of step size between several links.
The chain has 52 leading links, a groove of 1.3 mm for a 35 cm tire.
a saw with 52 links has a pitch of 38, a groove of 1.3 mm for tires 36 cm, and for tires 10 cm 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 40 cm tires (at 38 steps) and 57 main chain links.
For tools operated in extreme conditions, tracks made of metal alloys are used, giving them special strength.
Chainsaw equipment with special tracked part
Often, for the safe operation of the saw, it is only necessary to take care of the serviceability of all nodes of the mechanism. A correctly mounted caterpillar will prevent the possibility of injury, and its installation will not cause special problems for the master.
When it comes to mounting the circuit, you should prepare the tool for work in advance:
The chain should be well ground, then the work will be safe.
Operation will become safe if the chain is sharpened and well tensioned. However, it is not enough just to correctly install the chain on the chainsaw, you should regularly monitor the operating condition of the track.
At the beginning of work, the saw tire is inspected: it is fixed with a cover on the clutch.
When replacing the chain with a wrench, untwist the nuts securing the chain sprocket cover. Do not simultaneously release the tension of the chain brake device.

To perform dismantling, the brake stop is moved to the side. Pay attention to the holes through which the chain is tensioned.
The saw bar is moved to the left by touching the drive sprocket. Extreme attention is required from the worker: he makes sure that the teeth of the upper part of the chain are turned towards the sprocket. One part of the chain is attached to the leading part, and the shanks are fixed in the grooves of the tires.
The chain is tensioned as a result of adjustment with a screw that is attached to the surface of the clutch mechanism. After mounting the covers, slightly tighten the nuts. The saw bar is in the upper position, and the nuts are finally fixed. Check the free distance of the track on the tire. The drum should rotate very easily when the chain slides over the tire.
Slicing wood with a chainsaw tooth.
Installing the chain involves checking its tension after each refueling session. A poorly fixed part slides off the tire surface and injures the worker.
Inspect the tension with your hands, protecting them with mittens. In addition, new chains change their length during operation, so the check should be carried out very often.
Sometimes in the process of operation an important detail arises: it is not possible to install the circuit without additional heating and its corresponding deformation from the side of the lower part of the tire.
Saw track tension control
Not a single working professional will ignore chain tension in a chainsaw. By slightly pulling the caterpillar, it instantly estimates the amount of chain stretching. The sound appearing at the moment of impact can be muffled and short.
Caterpillar tension is carried out sequentially, performing several simple operations. Inspect the fuel cock. The worker needs to make sure that the fuel system is blocked. You can remove the spark plug wiring or open the decompression valve. The plug of the saw is pulled out of the outlet. The chain is rotated in the direction of its rotation during operation.
File position when sharpening the chainsaw chain.
Chain tension defects are visually noticeable: lower sagging of the track is formed. Control is carried out by adjusting the circuit at certain time intervals. In the upper part of the shank there should be a constant supply, formed when the chain is pulled. With very strong pulling, the caterpillar barely turns and quickly stops its movement.
Chain adjustment in working position is not allowed. Such negligence leads to deformation of the tire or damage to the crankshaft.
The track tension during operation 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 the chain, tension is only carried out under favorable weather conditions.
Caterpillar links can only be lubricated with clean oil, preventing them from entering the ground and dirt.
With a long load on the saw, two chains should be used, alternating their work.
Saw caterpillar brake performance monitoring
To protect the working person from damage by a chainsaw, a brake device is used. With its help, the tool is stopped until the tire hits the body of the worker.
The device is a typical chainsaw.
The circuit stop depends on two conditions:
- braking speed;
- tool turn-on time.
The saw is launched using 2 methods: contact and inertial. To protect the operator from tossing the chainsaw, the brake is equipped with a shield, which rests the hand of the worker. Some saws have protective bars masking the cutting part of the tool.
Do-it-yourself update of the cutting part of the saw
To solve the problem of sharpening the chain, special devices are used. The work is carried out based on the particular configuration of the tooth. At one of the cutting edges, the upper part is slightly beveled at an angle, therefore, in the process of intensive work, the operator needs to carry out 2-3 sharpening of the tool.
The interaction of the cutting edge with the ground blunts it, and the shavings change their size. The saw glides over the surface of the tree during operation. The main sign of a dull tool is an increase in the feed moment and the formation of small chips. When working with a blunt tool, the operator quickly gets tired, and the result of labor does not change for the better.
To work on grinding teeth prepare a tool:
- flat file;
- sawdust hook;
Given the contours of the tooth surface and the composition of the metal of the 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 sharpening the tooth. Its upper part rises above the tooth face by 20% of the tool diameter. Hold the file at an angle of 90 ° vertically and at 30 °. horizontally.
The holder is attached to the tooth, and its tool tightly touches, allowing the file to be located at the height required for work.
Before starting work, it is necessary to fix the tire. The first file movements should be smooth, soft, with regular turns of the tool. First of all, the teeth are 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 depth gauge is protected from grinding by the template, which is placed in the slot when an additional element is applied. Replacement of links during operation is not allowed, otherwise there may be a violation in the functioning of the saw. The use of special kits allows the correct sharpening of the tool with uniform processing of the edges of the tooth.
The general scheme of the operation consists of several points:
- chain brake fixation;
- mounting the tool according to the template;
- designations of the first tooth;
- direct process execution.
Correctly carried out installation of the chain on a tool for cutting wood will prevent technological losses, make the entire working process safe, and will allow you to cut wood without any problems for any purpose.
