Lubrication
(Refer to Lubrication Chart in Figure 14.)
WARNING: Always stop engine and
disconnect spark plug wire before
cleaning, lubricating or doing any kind of
work on lawn mower.
Figure 14: Lubrication Chart
Blade Control
• Lubricate the pivot points on the blade control
handle and the brake cable at least once a season
with light oil. The blade control must operate freely
in both directions.
Rear & Side Discharge Doors
• The torsion springs and pivot points should be
lubricated periodically with light oil to prevent any
rust or binding. Door must work freely.
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.
Engine
• Follow engine manual for instruction and schedule
of lubrication.
NOTE: When tipping the unit, empty the fuel tank and
keep engine spark plug side up.
Blade Care
WARNING: When removing the cutting
blade for sharpening or replacement,
protect hands by using heavy gloves or a
thick rag to grasp the cutting blade.
• Periodically inspect the blade adapter for cracks,
especially if you strike a foreign object. Replace
when necessary.
• Remove the bolt and blade support or bell washer
which hold the blade and adapter to the engine
crankshaft. See Figure 15. Remove the blade and
adapter from the crankshaft.
Figure 15
• 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.
NOTE: An unbalanced blade will cause excessive
vibration when rotating at high speeds and may cause
damage to the mower and/or personal injury.
• The blade can be tested by balancing it on a round
shaft screwdriver. See Figure 16. 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.
Figure 16
• Before reassembling the blade and the blade
adapter to the unit, 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 15.
Place the blade with the side marked bottom (or
with part number) facing away from the adapter.
