With varying cutter lengths, the cutter heights

also vary and cause rough running of the saw

chain and chain breakage.

► All cutters must be filed down equal to the

length of the shortest cutter – ideally, one

should have this done by a servicing dealer

using an electric sharpener

Depth gauge setting

689BA023 KN

The depth gauge determines the depth to which

the cutter penetrates the wood and thus the chip

thickness.
a Required distance between depth gauge and

cutting edge

When cutting softwood outside of the frost sea‐

son, 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.

► Check the depth gauge setting after each

sharpening

689BA061 KN

► 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.

689BA051 KN

► Rework the depth gauge so that it is flush with

the file gauge

689BA044 KN

► 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
