Prerequisite: All of the tools and equipment

saw teeth, depth gauge, round and flat files)
are ready for use.

File gauge for saw teeth, depth gauge and
flat files are not provided. Round files are in-
cluded!
◼
Clamp the guide rail and the chainsaw
firmly in the vice of a workbench.
◼
Place the file gauge on the saw chain
−
Arrows on the file gauge point in the
chain direction of rotation.
−
Ensure that the file gauge is fully in
contact with the saw chain.
◼
Place the correct sized round file on the
guides of the file gauge.
−
Using the round file at the
prescribed file angle (25° - 35° depending
on the type of chain) and holding it with
two hands, sharpen every second saw
tooth with even file movements away
from the body.
◼
Remove the guide rail from the vice and
clamp it in the opposite direction.
