SECTION 7: SERVICE
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 8: MAINTAINING YOUR TILLER
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.
Your engine is equipped with a oil drain pipe and cap
located on the bottom right side of the engine which will
help in draining the oil from the engine. Always drain oil
when it is warm. To drain oil, remove cap and drain oil
into a suitable container. Dispose of oil properly.
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.
We do not recommend the use of pressure washers to
clean your unit. They may cause damage to electric
components, spindles, pulleys, bearings, or the engine.
The use of pressure washers will result in shortened life
and reduce serviceability.
Belt Replacement
WARNING: Do not use an off-the-shelf
belt.
Your tiller has been engineered with a belt made of
special material (Kevlar Tensile) for longer life and
better performance. It should not be replaced with an
off-the-shelf belt.
If belt replacement is required, order belt by part
number from your nearest authorized dealer.
