hOW TO ShARPEN ThE cUTTERS
See Figures 20 - 23.
WARNING:
Improper chain sharpening increases the potential of
kickback. Failure to replace or repair damaged chain can
cause serious injury.
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.
 Tighten the chain tension enough that the chain does not
wobble. Do all of your filing at the mid-point of the bar.
Wear gloves for protection.
 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. Oc-
casionally remove filings from the file with a wire brush.
Problem

smoking.
