DESCRIPTION
Sharpening the Chain
Sharpening Instructions (Fig.37)
Using a depth
gauge joiner
Using a flat
file to round
the front
corner on a
depth gauge
When the cutting edges of the
blade become dull, they can be re-
sharpened with a few strokes of a file.
In order to keep the blade in
balance, all cutting edges must be
sharpened equally.
In addition, inspect the chain for
correct adjustment (more frequently
with a new chain). The chain should
feel snug but still pull freely. See
Figure 36. Refer to page 16 for
adjustment procedures.

IMPORTANT!
File all cutters to the same angle and
depth! Unequal filing may cause the
saw to vibrate or cut erratically!
NOTE:
For consistent filing angles, use a
filing guide such as Oregon
姞
p/n
31692 or equivalent.
1. Using a 4.5 mm round file, sharpen
all cutters to a 30
°
angle. Make
sure that one fifth (20%) of the file’s
diameter is always held above the
cutter’s top plate.
2. After all cutters are sharpened, use
a depth gauge joiner (Oregon
姞
p/n 106738 or equivalent) to
measure the height of each depth
gauge.
3. As required, lower the depth
gauges to a height of 0.020 inch.
Use a flat file; (Oregon
姞
p/n 12211
or equivalent).
4. After all depth gauges have been
adjusted, use a flat file to round
each depth gauge leading edge to
its original curvature and angle.
