Correctly sharpened chain
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, cause high vibrations,
produce unsatisfactory cutting results
and a higher rate of wear.
: Clean the chain.
:
Check the chain
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.
It is absolutely essential to comply
with the angles and dimensions
specified below. If the saw chain is
incorrectly sharpened – and in
particular if the depth gauge is set
too low – there is a risk of increased
kickback of the chainsaw, with
resulting risk of injury.
The chain pitch (e.g.
3
/
8
") is marked on
the depth gauge end of each cutter.
Use only special saw chain
sharpening files. Other files have the
wrong shape and cut.
Select file diameter according to chain
pitch – see table “Sharpening Tools”.
You must observe certain angles when
resharpening the chain cutter.
A = Filing angle
B = Side plate angle
Cutter shapes:
Micro = Semi-chisel
Super = Full chisel
The specified angles A and B are
obtained automatically if the
recommended files or sharpening tools
and correct settings are used.
