• Periodically inspect the blade adapter for cracks,

• When sharpening the blade, follow the original
angle of grind as a guide. It is extremely important
that each cutting edge receive an equal amount of
grinding to prevent an unbalanced blade. An
unbalanced blade will cause excessive vibration
when rotating at high speeds, and may cause
damage to the mower and/or personal injury.
