SECTION 9: SERVICE
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 11. The blade control must operate freely in
both directions.
Chute Deflector
The torsion spring and pivot point should be lubricated
periodically with light oil to prevent any rust or binding.
Deflector 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 lubrication instructions.
SECTION 10: MAINTAINING YOUR LAWN MOWER
WARNING: Be sure to disconnect and
ground the spark plug wire before
performing any repairs or maintenance.
NOTE: When tipping the unit, empty the fuel tank and
keep engine air filter side up.
Trouble Shooting
Refer to page 15 of this manual for trouble shooting
information.
Cutting Blade
When removing the cutting blade for sharpening or
replacement, protect hands by using heavy gloves or a
thick rag to grasp the cutting blade. Remove the bolt
and blade support which hold the blade and adapter to
the engine crankshaft. Remove the blade and adapter
from the crankshaft.
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, and may cause damage to the mower or cause
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.
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).
Install the blade adapter on the crankshaft with the
"star" away from the engine. Refer to Figure 12. 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.
