Top Plate Sharpening Angles (Fig. 35)
◾
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 Sharpening Angle (Fig. 36)
◾
CORRECT 80°- 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.
