HOW TO SHARPEN THE CUTTERS
Be careful to le all cutters to the specied 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.
