Blade Sharpening

CAUTION!

1. If the blade cutting edge is dull or nicked, it should be
replaced or sharpened.
2. Clean blade, blade washer and mounting surface of
all debris before replacing or sharpening.

See Figure 5-4. Sharpen only the top of the cutting
edge to maintain sharpness.

Refer to Figure 5-5:
4. Check blade balance by positioning the blade
horizontally on a nail or shaft through the center hole.
If either end of the blade rotates downward, grind
(remove) metal on that end until the blade will
balance. The blade is properly balanced when
neither end drops. Balance of a blade is generally
maintained by removing an equal amount of material
from each end of the blade when sharpening.
