HOW TO SHARPEN THE CUTTERS
Be careful to le all cutters to the specied
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 ling
at the midpoint of the bar. Wear gloves for
protection.
• Use a round le and holder.
• Keep the le level with the top plate of the
tooth. Do not let the le dip or rock.
• Using light but rm pressure, stroke
towards the front corner of the tooth. Lift
le away from the steel on each return
stroke.
• Put a few rm strokes on every tooth. File
all left hand cutters in one direction. Then
move to the other side and le the right
hand cutters in the opposite direction.
Occasionally remove lings from the le
with a wire brush.
CAUTION: 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 potential of kickback. Failure to
replace or repair damaged chain can cause
serious injury.
