How to Sharpen an Emery Chainsaw Chain
Chainsaw Sharp Chain. This is not only a condition for effective work, but also the main operational rule that provides safe working conditions for the worker. Therefore, the chain should always be sharp, and a dull element can lead to damage to the chainsaw at best. The worst option is possible injuries to humans.
Diagnostics. Which tool do you need?
Before proceeding with sharpening the chainsaw chain, a diagnosis should be made and checked for wear. The chain is considered worn when it is stretched and does not provide the necessary degree of tension. Such a circuit is not suitable for operation.
How to find out when it is necessary to sharpen?
There are no clear deadlines. On the one hand, this depends both on the quality of the chain saw and on the conditions and intensity of its use. Professional workers have to sharpen a saw several times a day. There are several signs that can be used to conclude that the chain has become dull. Among them:
Dull and sharp chain saw teeth- the sawing process is significantly slowed down;
– when sawing, it starts to drive the saw bar, which impedes the normal operation;
– the resulting chips become heterogeneous.
The sharp chain leaves the chips of the same shape, in the form of squares. A blunt saw leaves sawdust of various shapes, including dust and needle shavings.
If you haven’t saw sharpening machine and the practice of working on it, you should trust a specialist. If you are skilled enough to do this kind of work, then you need round and flat files to sharpen. The file should be selected specifically for your chain, since the choice of the necessary tool will make the process easier, and the result will be the most optimal. To sharpen the chain you need a template that fits your chain. You may also need a vise.

How to cut a chainsaw?
To understand how to sharpen the chain of the saw, you should know how the sawing process occurs. The chain consists of links (teeth), each of which acts on the tree like a planer. The link consists of a cutting tooth and a limiter tooth. The efficiency of the sawing process is directly dependent on the difference in height of these teeth. Stop teeth are usually 0.5-0.8 mm below the cutting element. Since the efficiency of the chainsaw depends on the work of all functional parts, the process of sharpening teeth should be the same for all links.
Sharpening cutting teeth
Manual chainsaw sharpening machineA template should be placed on the chain so that its arrows point in the direction of the chain. Sharpen should be easy and confident movements, so that the file directions are at an angle and point towards the tire. For different chains, you should choose your own angle of inclination, and this depends on the pitch of the chain. The teeth are sharpened in pairs: one on the left, the other on the right. If the template is clamped in a vice, then it is convenient to sharpen the teeth through one on one side, then on the other. During sharpening, the same number of file movements for each tooth should be strictly adhered to.
It should also be noted that the longer the tire, the larger the diameter of the trunk of the wood the saw will handle. At the same time, the length of the tire also depends on the power of the chainsaw itself. If the resource of the saw will not be enough for the length of the tire, then when cutting it is necessary to apply more physical effort. This in turn will accelerate the wear of structural parts of the chainsaw.
A flat file is used to sharpen the restrictive teeth. In order not to waste too much, you should use the template. Patterns have provisions for hardwood. “H” (hard) and soft. “S” (soft). Using a template is required. Otherwise, when sawing, the risk of kickback will increase, accuracy will decrease and vibration will increase.
Some more tips and tricks
” title =Each link (tooth) must be sharpened to the same length. To do this, measure the height of the shortest (dulled) tooth. It is also important not to violate the angle between the visor of the blade and the lateral plane, it should always be 90 degrees. The base of the internal opening of the tooth should always be in a horizontal plane. When sharpening, damage to the depth gauge should be avoided, which regulates the immersion of chain teeth in wood.
When sharpening with a machine, you should know that the device removes the same metal layer from the cutting tooth and limiter. The rounding of the stopper hole must always be maintained in its original size. Therefore, so that its size remains the original, after every third grinding, the depth of the hole should be increased.
The peculiarity of sharpening a saw is that it must be carried out strictly according to the rules. A uniform approach to sharpening and compliance with the design characteristics of the chainsaw must be maintained. Only in this case will the greatest efficiency of the tool be ensured.
