30° between the file and the saw
chain; see Fig. 32 & 33. Always use
a file holder (available separately)
when sharpening saw chains by
hand. File holders have markings for
the sharpening angle.
6. Using light but firm pressure, stroke
towards the front corner of the
tooth. Lift the file away from the
steel on each return stroke.
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. 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.
