5. Push the file toward the outside of the cutter with pressure against the side
plate edge. Maintain the same relationship between the guide lines and the
side of the chain and hold the guide level.
6. Release pressure against the cutting edge on the return stroke.
7. Continue to file the tooth until it's sharp. Do all the teeth on one side of the
chain first. Sharpen the teeth at the same point on the bar. Then move to
the other side of the chain and sharpen the remaining teeth . Try to use the
same number of strokes on all teeth as this will help to keep them all the
same length. You can check the length of the teeth with the scale on the depth
gauge tool. Each mark on the scale equals 1/ 16 inch.
