Required distance between depth
gauge and cutting edge
When cutting softwood outside of the
frost season, the distance can be
increased by up to 0.2 mm (0.008").
Lowering the depth gauges
The depth gauge setting is lowered
when the cutter is sharpened.
N
Check the depth gauge setting after
each sharpening
N
Lay the appropriate file gauge (1)
for the chain pitch on the saw chain
and press it against the cutter to be
checked – if the depth gauge
protrudes past the file gauge, the
depth gauge must be reworked
Saw chains with humped drive link (2) –
upper part of the humped drive link (2)
(with service mark) is lowered at the
same time as the depth gauge of the
cutter.
N
Rework the depth gauge so that it is
flush with the file gauge
N
Afterwards, dress the leading edge
of the depth gauge parallel to the
service mark (see arrow) – when
doing this, be careful not to further
lower the highest point of the depth
gauge
N
Lay the file gauge on the saw chain
– the highest point of the depth
gauge must be flush with the file
gauge
N
After sharpening, clean the saw
chain thoroughly, removing any
filings or grinding dust – lubricate
the saw chain thoroughly
N
In the event of extended periods of
disuse, store saw chains in cleaned
and oiled condition

The rest of the humped drive link
must not be filed; otherwise, this
could increase the tendency of the
chain saw to kick back.
Depth gauges that are too low
increase the kickback tendency of
the chain saw.
