When removing the cutting blade for sharpening or replacement. Protect your hands
with a pair of heavy gloves or use a heavy rag to hold the blade.

Remove the bolt and the washer that hold the blade and the blade adapter to the
engine crankshaft.
•
Remove the blade and the adapter from the crankshaft.
WARNING: periodically inspect the blade adapter for cracks, especially if you strike
a foreign object. Replace when necessary.
When sharpening the blade, follow the original angle of grind as 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. It may cause damage to the mower and could break causing personal injury.
The blade can be tested by balancing it on a round shaft screwdriver. Remove metal
from the heavy side until it balances evenly. It is recommended that the blade always be
removed from the adapter when testing for balance. Before reinstalling the blade and the
blade adapter to the unit, lubricate the engine crankshaft and the inner surface of the blade
adapter with light oil.

facing the ground when the mower is in the operating position.
