Maintaining and Sharpening
the Saw Chain
Sawing effortlessly with a properly
sharpened saw chain
A properly sharpened saw chain cuts
through wood effortlessly even with very
little pushing.
Never use a dull or damaged saw chain
– this leads to increased physical strain,
increased vibration load, unsatisfactory
cutting results and increased wear.

components and adapt these parts

accordingly
Compliance with the angles and
dimensions listed below is absolutely
necessary. An improperly sharpened
saw chain – especially depth gauges
that are too low – can lead to increased
kickback tendency of the chain saw –
risk of injury!
The chain pitch marking (a) is embossed
in the area of the depth gauge of each
cutter.

and type of cutting.
The diameter of file to be used depends
