Depth Gauge Setting - Stihl HT-KM Manual De Instrucciones

English / USA
: Rotate the file at regular intervals
while filing to avoid one-sided wear.
: Use a piece of hardwood to remove
burrs from cutting edge.
: Check angles 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 – 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.
Specified distance or setting between
depth gauge and cutting edge = a:
This setting may be increased by 0.008"
(0.2 mm) for cutting softwood in mild
weather season – no frost.

Lowering depth gauges
The depth gauge setting is reduced
when the chain is sharpened because
the top plate of the cutter slopes
a
downward towards the back.
: Check the depth gauge setting
every time you sharpen the chain.

: 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.

level with the filing gauge.
