aRequired 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.
NCheck the depth gauge setting after each sharpening

NLay 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.
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.

NRework the depth gauge so that it is flush with the file gauge

NAfterwards, 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
WARNING
Depth gauges that are too low increase the kickback tendency of the chain saw.

NLay the file gauge on the saw chain
– the highest point of the depth gauge must be flush with the file gauge
NAfter sharpening, clean the saw chain thoroughly, removing any filings or grinding dust – lubricate the saw chain thoroughly
NIn the event of extended periods of disuse, store saw chains in cleaned and oiled condition
