SHARPENING THE CUTTERS
See Figures 37 - 40.
Be careful to file all cutters to the specified angles
and to the same length, as fast cutting can only be
obtained when all cutters are uniform.
WARNING:
The saw chain is very sharp. Always wear
protective 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.
Use a 5/32 in. diameter round file and holder.
Do all of your filing at the midpoint of the bar.
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 the 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.
Remove filings from the file with a wire brush.
WARNING:
Improper chain sharpening increases the
potential of kickback, which can result in
serious personal injury.
WARNING:
Failure to replace or repair a damaged chain
could cause serious injury.
NOTICE:
A dull or improperly sharpened chain can cause
excessive motor speed during cutting, which
may result in severe motor damage.
