HOW TO SHARPEN THE CUTTERS
Be careful to file all cutters to the specified 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 filing at the midpoint of the bar. Wear
gloves for protection.
• Use a round file and holder.
• 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 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. Occasionally remove filings from the file with a wire brush.
