Operating
6. Position the tooth to be sharpened in
the correct position with respect to
the grinding disc. First adjust ap-
proximately. Put the adjustment
wedge (G) down and move the tooth
forward with the adjusting screw (
I
),
until the bottom of the grinding disc is
positioned inside the cutting edge of
the tooth.
Common chainsaw chains have a cutting-teeth
angle of 25° or 30°. The cutting-teeth angle is
usually printed on the package of a new chain.
If you do not know the exact cutting-teeth angle
of your chainsaw chain, it is normally sufficient
to estimate it by sight. Position the grinding disc
(E), as shown in the drawing.
7. Fasten the chainsaw chain in this position by
tightening the fastening screw (F). Make sure
the chainsaw chain is between both press
boards (M).
8. Start grinding with the most worn-out tooth.
Adjust the depth limiter (N) that way to en-
sure that all teeth are sharpened to the same
depth.
Successive teeth of chainsaw chains are
always at opposite angles. First sharpen all
teeth in one direction i. e. every second
tooth, before changing the sharpening angle
to the opposite direction. Make sure that all
teeth are sharpened as evenly as possible.
Only sharpen the teeth, never the chain
links.
