(5) 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 unbalanced blade will cause excessive vibration when rotating at high speeds and may cause
damage to the unit.
HAMMERS
The hammers, located inside the housing, may be reversed when they become dull. It is suggested that
this procedure be performed by your Mighty Mac servicing dealer.
ENGINE SPEED
Your engine speed has been factory set. Do not attempt to increase engine speed, or it may result in
personal injury. If you believe the engine is running too fast or too slow, take your leaf shredder-chipper
to the nearest Mighty Mac servicing dealer.
