BLADE CARE

WARNING
When removing the cutting blade for replacement, protect your hands with a pair
of heavy gloves or use a heavy rag to hold the blade. Do not repair or alter blade.
Periodically inspect the blade adapter for cracks, especially if you strike a foreign
object. Replace when necessary. Follow the steps below for blade service (Figure
10).
1. Disconnect spark plug boot from spark plug. Turn mower on its side making sure
that the air filter and the carburetor are facing up.
2. Remove the bolt and the blade bell support which hold the blade and the blade
adapter to the engine crankshaft.
3. Remove blade and adapter from the crankshaft.
4. Remove blade from the adapter for testing balance. Balance the blade on a
round shaft screwdriver to check. Remove metal from the heavy side until it
balances evenly. When sharpening the blade, follow the original angle of grind.
Grind each cutting edge equally to keep the blade balanced.
5. Lubricate the engine crankshaft and the inner surface of the blade adapter with
light oil. Slide the blade adapter onto the engine crankshaft. Place the blade
on the adapter such that the side of the blade marked "Bottom" (or with part
number) faces the ground when the mower is in the operating position. Make
sure that the blade is aligned and seated on the blade adapter flanges.
6. Place blade bell support on the blade. Align notches on the blade bell support
with small holes in blade.
7. Replace hex bolt and tighten hex bolt to torque: 29.5-33.2 ft-lb (40-45 Nm) max.
WARNING
An unbalanced blade will cause excessive vibration when rotating at high speeds.
It may cause damage to mower and could break causing personal injury.
