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 can cause it to break.

► Find the shortest cutter and then file all other

cutters back to the same length. It is best to

have this work done by a servicing dealer 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.
a Specified distance or setting between depth

gauge and cutting edge.

This setting may be increased by 0.2 mm

(0.008") for cutting softwood in the mild weather

season – no frost.

Lowering depth gauges

The depth gauge setting is reduced when the

chain is sharpened.

► Use a filing gauge to check the setting every

time you sharpen the chain.

► Place a filing gauge (1) that matches the chain

pitch on the chain and press it against the cut‐

ter – if the depth gauge projects from the filing

gauge, the depth gauge has to be lowered.

Saw chains with humped drive link (2) – upper

part of humped drive link (2) (with service mark)

is lowered along with the depth gauge.

WARNING

The other parts of the humped drive link must not

be filed since this may increase the kickback ten‐

dency of the power tool.

689BA051 KN

► File down the depth gauge until it is level with

the filing gauge.

689BA044 KN

► File the top of the depth gauge parallel to the

stamped service marking (see arrow) – but do

not lower the highest point of the depth gauge

in this process.
