Top-Plate Sharpening Angles
(Fig . 33)
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 . 34)
CORRECT 60° – 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.
