7. Make a few firm strokes on every
tooth. File all left-hand cutters in
one direction. Then move to the
other side and file the right-hand
cutters in the opposite direction.
Occasionally remove filings from the
file with a wire brush (Fig. 36).
WARNING:
sharpened chain can cause excessive
motor speed during cutting, which may
result in severe motor damage.

WARNING:
Top Plate Sharpening Angles (Fig. 37)
◾
CORRECT 35°- This optimal angle
can be obtained only when the
specified files and proper setting
are used. File holders are marked
with guide marks to align the file
properly to produce the correct top
plate angle.
◾
LESS THAN 35°- The tooth is too
dull for cutting.
◾
MORE THAN 35°- The edge of the cutting tooth is feathered and dulls quickly.
Side Plate Angle (Fig. 38)
◾
CORRECT 55° - The optimal angle
can be produced automatically if the
correct diameter file is used in the
file holder.
◾
HOOK - "Grabs" and dulls quickly.
Increases potential of KICKBACK.
Results from using a file with a
diameter that is too small, or a file
held too low.
