SECTION 8: MAINTAINING YOUR LAWN MOWER
WARNING: Always stop engine and
disconnect spark plug wire before
cleaning, lubricating or doing any kind of
work on lawn mower.
Blade Control
• Lubricate the pivot points on the blade control
handle and the brake cable at least once a season
with light oil. See Figure 10. The blade control must
operate freely in both directions.
Wheels
• Lubricate the wheel bearings (if so equipped) at
least once a season with light oil (or engine oil).
Also, 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.

SECTION 9: SERVICE
WARNING: Be sure to disconnect and
ground the spark plug wire before
performing any repairs or maintenance.
NOTE: When tipping the unit, empty fuel tank and keep
engine spark plug side up.
Cutting Blade
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 bell support which hold
the blade and adapter to the engine crankshaft.
See Figure 11. 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.
Figure 11
• 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, 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 for
the best test of balance.
