HOW TO SHARPEN THE CUTTERS

(See Figure 22-25)

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 file the right hand cutters in the opposite direction. Occasionally remove

lings from the le with a wire brush.

C A U T I O N

Dull or improperly sharpened chain can cause excessive motor speed during cutting which may

result in severe motor damage.

W A R N I N G

Improper chain sharpening increases the potential of kickback. Failure to replace or repair

damaged chain can cause serious injury.
