Saw Chain
Correctly sharpened chain
The pruner’s saw chain cannot be
locked in place on the guide bar.
Therefore, it is best to remove the
chain from the bar and resharpen it
on a workshop sharpening tool
(FG 2, HOS, USG).
Select the file diameter according to the
chain pitch (see table "Sharpening
Tools" at the end of this chapter).
A properly sharpened chain slices
through wood effortlessly and requires
very little feed pressure.
You must also observe the following
angles when resharpening the chain
cutters.
Do not work with a dull or damaged saw
chain as it will increase the physical
effort required, cause higher vibrations,
produce unsatisfactory results and a
higher rate of wear.
:
Select the appropriate sharpening
tools for the chain pitch.
See "Specifications" for the
permitted chain pitches.

parts to the shape and size of the
original parts by filing back as
necessary.
