Proper sharpening the chain of the chainsaw with a file

It is easiest to start sharpening directly on the tire, but some manufacturers oppose this, citing various arguments, and recommend removing the chain from the device and securing it in a vice. But this is extremely inconvenient, because after sharpening each link, you have to dismantle the chain and reinstall it.

If, nevertheless, the chain is sharpened directly on the saw, the weight of the tire can move under pressure from the hand with a file, so you need to set a stop, for example, a block of wood, from the back edge for the tire. It is important to clean the chain from sawdust, grease and debris before sharpening. This will simplify the work.

Correct file chain sharpening

Begin sharpening with the most honed tooth. It is on it that everyone else will be aligned. If the tooth is broken, it must be replaced by unfastening the chain with a special machine and installing a new element of the appropriate size and type. After the item is selected, sharpening begins. A file is moved directly from itself along the semicircular edge of the sawing tooth, resting against the edge of the adjacent chain link with a template. In this case, it is necessary to observe the parallelism between the file and the plane of the surface on which the saw or vice is mounted, as well as the angle of the guide indicated on the plate template.
Thus, all chain links are processed alternately through one, i.e. only those that are on one side of it. At the end, they move to the other half of the links and perform the same operation, but at the opposite angle, also indicated on the guide in the template. After completion, the file for sharpening the chain of the chainsaw is laid aside, and the chain is swept with a brush, eliminating metal shavings.
