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.
N
Find the shortest cutter and then file
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
mild weather season – no frost.
Lowering depth gauges
The depth gauge setting is reduced
when the chain is sharpened.
N
Use a filing gauge to check the
setting every time you sharpen the
chain.
N
Place a filing gauge (1) that
matches the chain pitch on the
chain – if the depth gauge projects
from the filing gauge, the depth
gauge has to be lowered.
N
File down the depth gauge until it is
level with the filing gauge.
N
File the top of the depth gauge
parallel to the stamped service
marking (see arrow) – but do not
lower the highest point of the depth
gauge in this process.
N
Place the filing gauge on the chain –
the highest point of the depth gauge
must be level with the filing gauge.
