There are signs of wear of a saw, which is a signal that it needs to be sharpened:
- need to make greater effort when sawing;

- burn the edges of the cut there is the smell and dark marks from the saw teeth;

- increased temperature of the protective casing of the engine (until it smoke).

If you prefer to remove the disc from the machine, clamp it in a vise with wooden planks and exactly follow the above procedure. As grinding of teeth rotate the disk in a vise.

At the end of grinding of all teeth, insert the disc into the machine, turn it on in network and sawed unnecessary wooden block. In case of strong noise or uneven flow of material, check whether the same saw teeth height. For this the cutting edge, lift the handle and then rotate the disc a full turn in the direction opposite to the direction of rotation. Inspect the disk. Each tooth will remain featured, which allows to reveal the teeth that is different from the other in height. Gently reduce file the size of the long teeth.
