Filing Cutter Depth Gauges
The cutter depth gauge clearance is reduced
as cutters are sharpened. After every second
or third sharpening, 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 21).
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 22).
After several hand filings, have authorized
service center or sharpening service machine
sharpen chain. This will insure even filing.
