Saw chain parameters
A saw chain is made of repeating segments. A
complete segment is shown below, it consists
of a left cutter followed by a link and a right
cutter followed by a link. Each cutter or link
is linked to a guiding element, that keeps the
chain on the blade:
Left
cutter
Rotation direction
Each cutter consists of a cutting angle A and a
top plate angle B. Both of these angles can be
sharpened on the chain sharpener. The depth
gauge C is filed by hand.

Check the user manual of your chain
saw or saw chain in order to figure
out the correct grinding angles.

For most chains, the cutting angle A should
be between 50°-60°. On this sharpener, the
cutting angle is fixed to 60°. The top plate an-
gle B (set on the vise angle scale 10), should
be between 30°-35°.
Depth gauge
Right
cutter After the cutters have been sharpened, en-
sure that the depth gauge is respected. The
depth gauge has to be lower than the cutters.
Check the depth gauge of your chain in the
saw chain specifications. If necessary, file the
depth gauge using a file with file guide (not
included).
For most chains, the depth gauge C is
0.025" - 0.050" or 0.64 mm - 1.28 mm.
The saw chain is worn out and cannot be
sharpened if the depth gauge C is at the same
level as the indicator on the guiding element:
