marked on the file holder. Rest the
file holder on the top plate and depth
gauge.
Always file from the inside to the
N
outside of the cutter.
The file only sharpens on the
N
forward stroke – lift the file off the
cutter on the backstroke.
Avoid touching the tie straps and
N
drive links with the file.
Rotate the file at regular intervals
N
while filing to avoid one-sided wear.
Use a piece of hardwood to remove
N
burrs from the cutting edge.
Check angles with the filing gauge.
N
All cutters must be the same length.
If the cutters are not the same length,
they will have different heights. This
makes the chain run roughly and can
cause it to break.
Find the shortest cutter and then file
N
all other cutters back to the same
length. It is best to have this work
done in the workshop on an electric
grinder.

Depth gauge setting
The depth gauge determines the height
at which the cutter enters the wood and
thus the thickness of the chip removed.
a Specified distance or setting
between depth gauge and cutting
edge.
This setting may be increased by
0.2 mm (0.008") for cutting softwood in
the mild weather season – no frost.

The depth gauge setting is reduced
