Saw Chain
Correctly sharpened chain
A properly sharpened chain slices
through wood effortlessly and requires
very little feed pressure.
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 (se table "Sharpening Tools"
at the end of this chapter).
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, produce unsatisfactory
results and a higher rate of wear.

tools for the chain pitch.
