- Hold the file’s diameter 20% above the cutter’s top plate, so that the file is in the correct position
- Make sure the top plate filing angle is parallel to chainsaw chain centerline.
- Sharpen using even strokes in the most damaged area of the cutter to remove damage. When the cutter is shiny and silver it means that the damage is removed
- Before switching to another side of the change, complete all the cutters on one side.
