5. File from inside towards outside of cutter until
sharp. Only file in this one direction (see Figure
23).
Note:
Two or three strokes with file should
sharpen cutter.
6. After each cutter is sharpened, move chain for-
ward to sharpen next cutter. File all cutters on
one side of chain.
7. Move to other side of chain and repeat process.
Filing Cutter Depth Gauges
The cutter depth gauge clearance is reduced as cutters
are sharpened. After every second or third sharpen-
ing, reset cutter depth gauges.
1. Place depth gauge tool (.025") firmly across top
of two cutters. Make sure depth gauge enters slot
in depth gauge tool (see Figure 25).
2. Use medium flat file. File depth gauge level with
depth gauge tool.
3. Remove depth gauge tool. With flat file, round
off front corner of cutter depth gauge (see Figure
26).
After several hand filings, have authorized service
center or sharpening service machine sharpen chain.
This will insure even filing.
