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