MAINTENANCE
SHARPENING 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.
• Tension the chain prior to sharpening. Refer to Adjusting The Chain Tension.
• Use a 5/32 in. (4 mm) diameter round le and holder. Do all of your ling at the midpoint of
the bar.
• Keep the le level with a 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 the 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.
• Remove lings from the le with a wire brush.
