5. Keep a correct sharpening angle of
30° between the le and the saw
chain; see Fig. 32 & 33. Always use
a le holder (available separately)
when sharpening saw chains by
hand. File holders have markings for
the sharpening angle.
6. Using light but rm pressure, stroke
towards the front corner of the
tooth. Lift the le away from the
steel on each return stroke.
7. Make a few rm strokes on every
tooth. File all left-hand cutters in
one direction. Then move to the
other side and le the right-hand
cutters in the opposite direction.
Occasionally remove lings from the
le with a wire brush (Fig. 34).
WARNING:
A dull or improperly
sharpened chain can cause excessive
motor speed during cutting, which may
result in severe motor damage.
WARNING:
Improper chain
sharpening increases the potential of
kickback.
WARNING:
Failure to replace or
repair a damaged chain can cause serious
injury.
