• Use the midpoint of the file bar.
• Use light but firm pressure when sharpening the
surface.
• Lift the file away on each return stroke.
• Sharpen the cutters on one side and then move to
the other side.
Replace the chain if:
• The length of the cutting edges is less than 1/5 in. (5

and the rivets.
• The cut speed is slow.
• Sharpening the chain many times but it does not
increase the cutting speed. The chain is worn.
