HOW TO SHARPEN THE CUTTERS
See Figures 20 - 23.
Be careful to file all cutters to the specified angles
and to the same length, as fast cutting can be
obtained only when all cutters are uniform.
WARNING:
The saw chain is very sharp, always wear pro-
tective gloves when performing maintenance
to the chain to prevent serious personal injury.
Properly tension the chain prior to sharpening.
Refer to Adjusting the Chain Tension earlier in
this manual. Do all of your filing at the mid-point
of the bar.
Use a 5/32 in. diameter round file and holder.
Keep the file level with the top plate of the tooth.
Do not let the file dip or rock.
Using light but firm pressure, stroke towards
the front corner of the tooth. Lift file away from
the steel on each return stroke.
Put 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.
WARNING:
Improper chain sharpening increases the po-
tential of kickback, which can result in serious
personal injury.
WARNING:
Failure to replace or repair damaged chain can
cause serious injury.
NOTICE:
A dull or improperly sharpened chain can cause
excessive engine speed during cutting, which
may result in severe engine damage.
