• Repeat for each depth gauge on the
chain.
After setting the depth gauge, sharpen
the cutters:
• Place the chain file into the file guide.
• Align the file guide so that the correct
top plate filing angle marked on the file
guide is parallel to the chain (Fig. 37).
• Sharpen cutters on one side of the chain
first. Make 3-4 strokes with the file from
the inside of each cutter to the outside.
Use the same number of strokes on
each cutter. Then, turn the pole saw
around and repeat for cutters on the
other side of the chain (Fig. 38).
• File back any damage on the chrome
top or side plates (Fig. 39).
