hesitate while turning, but the engine maintains the
same speed.
To adjust the tension on the belt, refer to final clutch
adjustment in Assembly Instructions.
CARBURETOR ADJUSTMENT
WARNING: If any adjustments are made
to the engine while the engine is running,
(e.g. carburetor), disengage all clutches
and tines. Keep clear of all moving parts.
Be careful of heated surfaces and muffler.
Never make unnecessary adjustments. The factory
settings are correct for most applications. If adjust¬
ments are needed, refer to the separate engine man¬
ual packed with your tiller.
LUBRICATION
Transmission —The transmission is pre-lubricated
and sealed at the factory. It requires no checking
unless the transmission is disassembled. To fill with

at least once a season with light oil.
MAINTENANCE
A WARNING: Disconnect the spark plug wire
and ground it against the engine before
performing any repairs or maintenance.
ENGINE
Refer to the separate engine manual for engine
maintenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.
Service air cleaner every ten hours under normal
conditions. Clean every hour under extremely dusty
conditions. Poor engine performance and flooding
usually indicates that the air cleaner should be ser¬
viced. To service the air cleaner, refer to the separate
engine manual packed with your unit.
IMPORTANT: Never run your engine without air
cleaner completely assembled.
The spark plug should be cleaned and the gap reset
every 25 hours of engine operation. Spark plug
replacement is recommended at the start of each tiller
season; check engine manual for correct plug type
and gap specification.
Clean the engine regularly with a cloth or brush.
Keep the cooling system {blower housing area) clean
to permit proper air circulation which is essential to
engine performance and life. Be certain to remove all
dirt and combustible debris from muffler area.
CLEANING THE TINE AREA
Clean the underside of the tine shield after each use.
The dirt washes off the tines easier if washed off
immediately instead of after it dries.
8

TIRES
Recommended operating tire pressure is approxi¬
mately 12 p.s.i. (check sidewall of tire for tire manu¬
facturer’s recommended pressure). Maximum tire
pressure under any circumstances is 30 p.s.i. Equal
tire pressure should be maintained on both tires.
When installing a tire to the rim, be certain rim is
clean and free of rust. Lubricate both the tire and rim
generously. Never inflate to over 30 p.s.i. to seat
beads.
A WARNING: Excessive pressure (over 30
p.s.i.) when seating beads may cause
tire/rim assembly to burst with force suf¬
ficient to cause serious injury.
