 If cutter teeth have hit hard objects such as nails
and stones, or have been abraded by mud or
sand on the wood, have service dealer sharpen
chain.
NOTE: Inspect the drive sprocket for wear or dam-
age when replacing the chain. If signs of wear or
damage are present in the areas indicated, have
the drive sprocket replaced by a service center.
How to Sharpen the Cutters
See Figures 40 - 41.
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.

 Wear gloves for protection. Properly tension
the chain prior to sharpening. Refer to Chain
Tension section 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.
Improper chain sharpening increases the po-
tential of kickback.
Failure to replace or repair damaged chain can
cause serious injury.
