any blade that is bent, excessively nicked, worn, or has
any other damage. Small nicks can be ground out
when sharpening.

NOTICE
When sharpening blades, be sure to balance
them. Unbalanced blades will cause excessive
vibration which can damage blade spindle bear-
ings. Vibration may also cause structural cracks in
mower components.
1. Remove blades.
2. Always sharpen both ends at the same time to
maintain balance.
3. Follow original sharpening pattern.
4. Do not sharpen blade to a razor edge. Leave from
1/32" to 1/16" (0.8 - 2 mm) blunt edge.
5. Do not sharpen back side.
