Chain pitch
The chain pitch (a) is marked on the
depth gauge end of each cutter.
Select file diameter according to chain
pitch – see table “Sharpening Tools”.
You must observe certain angles when
resharpening the chain cutter.
Filing and side plate angles
A Filing angle
STIHL saw chains are sharpened to a
filing angle of 30°. Exceptions are
ripping chains with a filing angle of 10°.
Ripping chains have an X in their
designations.
B Side plate angle
The correct side plate angle is obtained
automatically if you use the prescribed
file holder and file diameter.
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.
File holder
N
Use a file holder
A file holder must be used for manual
resharpening (see table "Sharpening
Tools"). The correct filing angles are
marked on the file holder.
Use only special saw chain sharpening
files. Other files have the wrong shape
and cut.
For checking angles
Use a STlHL 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.
File correctly
N
Disconnect the plug from the wall
outlet.
N
Select sharpening tools according
to chain pitch.
N
Clamp the bar in a vise if necessary.
N
To rotate the chain – pull hand
guard against handle to disengage
the chain brake Hold the hand guard
in this position – the coasting brake
is disengaged.
N
Sharpen the chain frequently, take
away as little metal as possible –
two or three strokes of the file are
usually enough.
