: Hold the file horizontally for all
chain types (at right angle to side of
guide bar) and file according to the
angles marked on the file holder.
Rest the file holder on the top plate
and depth gauge.
: Always file from the inside to the
outside of the cutter.
: The file only sharpens on the
forward stroke – lift the file off the
cutter on the backstroke.
: Avoid touching the tie straps and
drive links with the file.
: Rotate the file at regular intervals
while filing – this avoids one-sided
wear.
: Use a piece of hardwood to remove
burrs from the cutting edge.
: Check angle with the filing gauge.
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
increases the risk of breakage of the
chain..
: Find the shortest cutter and then file
all other cutters back to the same
length. This can be very time
consuming – it is best to have this
work done in a 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.
Distance between depth gauge and
cutting edge = a:
This setting may be increased by 0.2mm
(0.008") for cutting softwood in mild
weather season – no frost.

Lowering depth gauges
The depth gauge setting is reduced
when the cutter is sharpened.
: Check the setting every time you
a
sharpen the chain.

: Use a filing gauge (1) that matches
the chain pitch and place it on the
chain. If the depth gauge is higher
than the filing gauge, it must be
lowered.
