Operation Manual

&RUUHFWO\VKDUSHQHGFKDLQ
A properly sharpened chain slices
through wood effortlessly and requires
very little feed pressure.
Do not work with a dull or damaged
chain as it will increase the physical
effort required, produce unsatisfactory
results and a higher rate of wear.

for cracks in the links and damaged
rivets -
replace any damaged or worn parts of
the chain and match the new parts to the
shape and size of the original parts.
,PSRUWDQW It is absolutely imperative to
comply with the angles and dimensions
specified below. If the VDZFKDLQLV
LQFRUUHFWO\VKDUSHQHG - and in
particular if the depth gauge is set too
low - there is a risk of increased
kickback of the chainsaw, with resulting

See "Technical Data" for the permitted
chain pitches.
The chain pitch (e.g. 3/8) is marked on
the depth gauge side of each cutter.

Other files have the wrong shape and
cut.
Select file diameter according to chain
pitch - see table at the end of this
chapter.
You must observe certain angles when
resharpening the chain cutters

Furthermore, the angles must be the

If angles are uneven:
Chain will run roughly, not in a straight
line, wear quickly and finally break.
