English
► 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 pro‐
trudes 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.
WARNING
The rest of the humped drive link must not be
filed; otherwise, this could increase the tendency
of the chain saw to kick back.
► Rework the depth gauge so that it is flush with
the file gauge
► Afterwards, dress the leading edge of the
depth gauge parallel to the service mark (see
arrow) – when doing this, be careful not to fur‐
ther lower the highest point of the depth gauge

26 Maintaining and Sharpening the Saw Chain
WARNING
Depth gauges that are too low increase the kick‐
back tendency of the chain saw.
► Lay the file gauge on the saw chain – the high‐
est point of the depth gauge must be flush with
the file gauge
► After sharpening, clean the saw chain thor‐
oughly, removing any filings or grinding dust –
lubricate the saw chain thoroughly
► In the event of extended periods of disuse,
store saw chains in cleaned and oiled condi‐
tion
