backstroke
Do not file tie straps and drive links

Rotate the file a little periodically in

Check angle with file gauge

All cutters must be equally long.
With varying cutter lengths, the cutter
heights also vary and cause rough
running of the saw chain and chain
breakage.
All cutters must be filed down equal
N
to the length of the shortest cutter –
ideally, one should have this done
by a servicing dealer using an
electric sharpener
Depth gauge setting
The depth gauge determines the depth
to which the cutter penetrates the wood
and thus the chip thickness.

gauge and cutting edge
When cutting softwood outside of the
frost season, the distance can be
increased by up to 0.2 mm (0.008").

WARNING
Rework the depth gauge so that it is
flush with the file gauge
Afterwards, dress the leading edge
of the depth gauge parallel to the
service mark (see arrow) – when
doing this, be careful not to further
lower the highest point of the depth
gauge
