SHARPENING THE CUTTERS
See Figures 38 - 41.
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.
CAUTION:
Make sure the chain saw is disconnected
from the power supply before you work on the
saw.
WARNING:
The saw chain is very sharp. Always wear pro-
tective gloves when performing maintenance to
the chain to prevent serious personal injury.
 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.
CAUTION:
A dull or improperly sharpened chain can cause
excessive motor speed during cutting, which
may result in severe motor damage.
WARNING:
Improper chain sharpening increases the poten-
tial of kickback.
