SECTION 9: ADJUSTMENTS
WARNING: Do not at any time make
any adjustment to lawn mower without
first stopping engine and disconnecting
spark plug wire.
CUTTING HEIGHT ADJUSTMENT
Adjustment may be made by removing and moving
axle bolts to desired position. Cutting heights will be
raised as axle bolts are moved to a lower hole and
lowered as axle bolts are moved to a higher hole in
the deck. All axle bolts must be mounted in the
same relative position. Cupped washers must be
assembled so that the cupped side of the washers
are against the deck. Refer to Figure 9.
CARBURETOR ADJUSTMENTS
WARNING: If any adjustments are
made to the engine while the engine is
running (e.g. carburetor), keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load. Refer to the separate engine
manual packed with your mower for carburetor
adjustment information.
NOTE: A dirty air cleaner will cause an engine to
run rough. Be certain air cleaner is clean and
attached to the carburetor before adjusting
carburetor.
SECTION 10: LUBRICATION
WARNING: Always stop engine and
disconnect spark plug wire before cleaning,
lubricating or doing any kind of work on
lawn mower.
Figure 14
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 14. 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 11: MAINTENANCE
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 spark plug side up.
TROUBLE SHOOTING
