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:

Rotation direction
Each cutter consists of a cutting an-
gle A and a top plate angle B. Both of
these angles can be set on the chain
sharpener. The depth gauge C is filed
by hand.

in order to figure out the correct
grinding angles.
For most chains, the cutting angle A
(set on the cutting angle scale  14)
should be between 50°-60° and the
Right
top plate angle B (set on the vise an-
cutter
gle scale 9), should be between 30°-
35°.
Depth gauge
After the cutters have been sharp-
ened, ensure 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.
Use the indicator to check the depth
gauge:
The saw chain is worn out and cannot
be resharpened if the depth gauge C
is at the same level as the indicator
on the guiding element:
Check the user manual of
your chain saw or saw chain
