The chain pitch (e.g. /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.

The specified angles A and B are
obtained automatically if the
recommended files or sharpening tools
and correct settings are used.
The angles must be the same on all
cutters. If the angles are uneven: Chain
will run roughly, not in a straight line,
wear quickly and finally break.
As these requirements can be met only
after sufficient and constant practice:
Use a file holder
N
A file holder must be used for manual
resharpening (see table "Sharpening
Tools"). The correct filing angles are
marked on the file holder.
For checking angles

Use a STIHL filing gauge (special
accessory, see table "Sharpening
Tools"). This is a universal tool for
checking the filing and side plate angles,
depth gauge setting, cutter length and
groove depth. It also cleans the guide
bar groove and oil inlet holes.

outlet.
Select sharpening tools according
N
to chain pitch.
Clamp the bar in a vise if necessary.
