MAINTENANCE
WARNING:
Improper chain sharpening increases the poten-
tial of kickback, which can result in serious
personal injury.

Failure to replace or repair damaged chain can
cause serious injury.
NOTICE:
A dull or improperly sharpened chain can cause
excessive motor speed during cutting which
may result in severe motor damage.
TOP PLATE FILING ANGLE
See Figure 34.
CORRECT 30° – File holders are marked with
guide marks to align file properly to produce
correct top plate angle.
LESS THAN 30° – For Cross Cutting.
MORE THAN 30° – Feathered Edge Dulls
Quickly.
SIDE PLATE ANGLE
See Figure 35.
CORRECT – 80° Produced automatically if cor-
rect diameter file is used in file holder.
HOOK – “Grabs” and dulls quickly. Increases
potential of KICKBACK.
Results from using a file with diameter too small,
or file held too low.
BACKWARD SLOPE – Needs too much feed
pressure, causes excessive wear to bar and
chain.
