Stihl HT 100 Instruction Manual page 39

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 by a servicing dealer 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.

Lowering depth gauges
The depth gauge setting is reduced
when the chain is sharpened.
Use a filing gauge to check the
N
setting every time you sharpen the
chain.

a
Place a filing gauge (1) that
N
matches the chain pitch on the
chain and press it against the cutter
– if the depth gauge projects from
the filing gauge, the depth gauge
has to be lowered.
Saw chains with humped drive link (2) –
upper part of humped drive link (2) (with
service mark) is lowered along with the
depth gauge.
WARNING
The other parts of the humped drive link
must not be filed since this may increase
the kickback tendency of the power tool.

File down the depth gauge until it is

File the top of the depth gauge
N
parallel to the stamped service
marking (see arrow) – but do not
lower the highest point of the depth
gauge in this process.
WARNING
The kickback tendency of the machine is
increased if the depth gauges are too
low.
