Anchor removed and cleaned of soot and change if necessary.Next, clean the contacts collector coils.You should also check their inductance ohmmeter, and if there are faults, then contact me.Often breaking is high friction between the cheek and the holder, which leads to jamming.If this is the case of breakage, the cheeks must be installed exactly perpendicular to the holders.

before the next tooth mark from which to start sharpening.When sharpening the first tooth to remember the number of movements, because the remaining teeth to be processed exactly the same.If the disc is removed from the machine, it is clamped in a vice using wooden timbers.

As sharpening disc should rotate.After completing the drive is installed on the machine and carried out a trial cut unnecessary bar.If you will be attending a lot of noise and uneven material feed, it is necessary to check the teeth height.If there are protruding teeth, they must be sawed to the general level.
