5. The blade may be resharpenedby removing
it and either grinding or filing the cutting edge
keeping as close to the original bevel as
possible. Do not attempt to sharpen the blade
while it is still on the mower.
6. It is extremely important that each cutting
edge receives an equal amount of grinding to
prevent an unbalanced blade.
NOTE: Improperblade balancewill result in
excessive vibration causing eventual damage to
the engine and mower. Be sure to carefully bal-
ance blade after sharpening. Possible damage
resulting from blade unbalancecondition isnot
the responsibility of the manufacturer.
