Chain Pitch
The chain pitch (a) is marked on the
depth gauge end of each cutter.
Mark (a) Chain Pitch
inch
7 1/4 P
1 or 1/4 1/4
6, P or PM 3/8 P
2 or 325 0.325
3 or 3/8 3/8
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
B
A Filing angle
50
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
a
The correct side plate angle is obtained
automatically if you use the prescribed
file holder and file diameter.
Cutter shapes
Micro = semi-chisel chain,
e.g. 63 PMC3, 26 RMC3,
36 RMC
mm
Super = full chisel chain,
6,35
e.g. 63 PS3, 26 RSC,
36 RSC3
6,35
Ripping chain, e.g.
9,32
63 PMX, 36 RMX
8,25
The angles must be the same on all
9,32
cutters. If the angles are uneven: Chain
will run roughly, not in a straight line,
wear quickly and finally break.
File holder
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.
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
Select sharpening tools according
N
to chain pitch.
If you use an FG 2, HOS or USG
N
sharpener: Remove the chain from
the bar and sharpen according to
the instructions supplied with the
tool.
