CARE AND MAINTENANCE
WARNING
• Improper chain sharpening increases the potential of kickback.
• Failure to replace or repair a damaged chain can cause serious injury.
Top Plate Sharpening Angles (Fig. 13e)
CORRECT 30°- This optimal angle can be obtained
only when the specified files and proper setting are
used. File holders are marked with guide marks
to align the file properly to produce the correct top
plate angle.
LESS THAN 30°- The tooth is too dull for cutting.
MORE THAN 30°- The edge of the cutting tooth is
feathered and dulls quickly.
Side Plate Angle (Fig. 13f)
CORRECT 55° - The optimal angle can be
produced automatically if the correct diameter file is
used in the file holder.
HOOK - "Grabs" and dulls quickly. Increases
potential of KICKBACK. Results from using a file
with a diameter that is too small, or a file held too
low.
BACKWARD SLOPE - Needs too much feed
pressure, causes excessive wear to bar and chain.
Results from using a file with a diameter too large,
or a file held too high.
Depth-Gauge Clearance
a. The depth gauge should be maintained at a
clearance of 0.025 in. (0.6 mm), as shown in
Fig. 13g. Use a depth gauge tool (available
separately) to check the depth gauge
clearances.
b. Check the depth-gauge clearance every time
the chain is filed.
