To adjust the tension on the belt, refer to clutch
adjustment information in “Checking the Clutch
Adjustment” section of the Assembly Instructions.
After belt tension has been adjusted, if the belt is
excessively stretched, you may need to adjust the
idler pulley rod. This can easily be checked. With the
engine off and the clutch control bail disengaged,
shift the gear selection handle to each forward
mode. If the indicator bracket touches the idler pulley
rod, (with the clutch control bail disengaged), then
an adjustment is necessary.
1. Disconnect and ground out spark plug wire
against the engine.
2. Remove the belt cover as described in the belt
replacement section on page 12.
3. Remove the hairpin clip and flat washer from the
idler pulley rod. See Figure 12.
4. Move the idler pulley rod to the lower hole in the
idler bracket. See Figure 12.
5. Replace the wave washer and hairpin clip.
6. Check clearance of the idler pulley rod to the
indicator bracket by shifting to each forward
mode, as before.
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
adjustments are needed, refer to the separate
engine manual packed with your tiller.
SECTION 10: LUBRICATION
Transmission—The transmission is pre-lubricated
and sealed at the factory. It requires no checking
unless the transmission is disassembled. To fill with
grease, lay the right half of the transmission on its
side. Add 30 ounces of Benalene 920 grease. Apply
a bead of RTV or silicone sealant to the right half of
the transmission, all the way around the gear
compartment. Assemble the left half to it. This
grease can be obtained at your nearest authorized
dealer. Order part number 737-0300. Clutch Bail—Lubricate the pivot point on the clutch
bail and the cable at least once a season with light
oil. The control must operate freely in both
directions.
Pivot Points—Lubricate all pivot points and linkages
at least once a season with light oil.
Tine Shaft—Remove tines at least once a season
and lubricate with oil.
Wheel Axle—Remove the wheel assemblies at least
once a season and lubricate with oil.
SECTION 11: MAINTENANCE
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
serviced. 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.
