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.
N Clean the saw chain
N Check the saw chain for cracks and
damaged rivets
N Replace damaged or worn chain
components and adapt these parts
to the remaining parts in terms of
shape and level of wear – rework
accordingly
WARNING
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.
Use only special saw chain files! Other
files are unsuitable in terms of shape
and type of cutting.
The diameter of file to be used depends
on the chain pitch – see table
"Sharpening tools".
The angles of the cutter must be
maintained during resharpening.
A Sharpening angle
B Side plate angle
When the specified files and/or
sharpening tools and the proper setting
are used, the specified values for angles
A and B will be attained automatically.
The angles must be identical for all
cutters in the saw chain. Varying angles:
Rough, uneven running of the saw
chain, increased wear – even to the
point of saw chain breakage.
Because these requirements can be met
only after sufficient, constant practice:
N Use a file holder
Always use a file holder (special
accessory, see table "Sharpening tools")
when sharpening saw chains by hand.
File holders have markings for the
sharpening angle.
