Wheels
• The wheels require no lubrication. However, if the
wheels are removed for any reason, lubricate the
surface of the axle bolt and the inner surface of the
wheel with light oil. Engine oil may also be used.
When tipping the unit, empty the fuel tank and keep
engine spark plug side up.

Blade Care
• Periodically inspect the blade adapter for cracks,
especially if you strike a foreign object. Replace
when necessary.
WARNING: When removing the cutting
blade for sharpening or replacement, protect
hands by using heavy gloves or a rag to grasp
the cutting blade.
To remove blade
• Remove the bolt and blade support or bell washer
which hold the blade and adapter to the engine
crankshaft. See Figure 14. Remove the blade and
adapter from the crankshaft.

To balance blade
• When sharpening the blade, follow original angle of
grind as a guide. It is extremely important to grind
off all edges equally to keep the blade balanced.
NOTE: An unbalanced blade will cause excessive
vibration when rotating at high speeds and may cause
damage to the mower and/or personal injury.
• Test the blade by balancing it on a round shaft
screwdriver. See Figure 15.
• Remove metal from the heavy side until it balances
evenly. Always remove blade from the adapter for
the best test of balance.

To reassemble blade
• Lubricate the engine crankshaft and the inner
surface of the blade adapter with light oil (or engine
oil). Also lubricate the bolt holes, bolts and inner
surface of the nuts.
• Install the blade adapter on the crankshaft with the
“star” away from the engine. Refer to Figure 14.
Place the blade with the side marked bottom (or
with part number) facing away from the adapter.
• Align the blade bell support over the blade with the
tabs in the holes of the blade and insert the hex
bolt. Tighten the hex bolt to the torque listed in the
“Blade Mounting Torque” section below.
Blade Mounting Torque
Center Bolt: 450 in. lbs. min., 600 in. lbs. max.
IMPORTANT:
To ensure safe operation, all nuts and
bolts must be checked periodically for correct tightness.
