MAINTENANCE
Balancing the Blade
(See Fig. 26)
When sharpening, care should be taken to keep the blade balanced. An unbalanced blade will
cause excessive vibration when the mower is running. This vibration will eventually cause damage
to the mower, especially the motor.
When removing, inspect the blade carefully. If the blade is bent or damaged, replace immediately
with a new blade. Failure to replace a bent or damaged blade could cause an accident resulting in
possible serious injury.
