Items Needed to Sharpen Chain
Purchase these items from your local dealer, hard-
ware store, or chain saw supplies outlet.
• 5/32" round file
• Depth gauge tool
• File guide
• Vise
• Medium sized flat file
Sharpening Cutters
Use file guide for 30° filing.
1. Adjust chain for proper tension (see
Saw Chain
Tension Adjustment
).
2. Clamp guide bar in vise to hold saw steady.
Note:
Do not clamp chain.
3. Press 5/32" round file (attached to file guide)
into groove between top plate and depth gauge
on chain. File guide should rest on both top plate
and depth gauge (see Figure 18).
Note:
File at
midpoint of guide bar.
4. Hold file guide level. Make sure 30° mark on
file guide is parallel to center of guide bar (see
Figure 18). This will insure that you file cutters
at 30° angle.
5. File from inside towards outside of cutter until
sharp. Only file in this one direction (see Figure
18).
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 20).
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
21).
After several hand filings, have authorized service
center or sharpening service machine sharpen chain.
This will insure even filing.
