disconnect spark plug wire before cleaning,
lubricating or doing any kind of work on tiller.

a season with light oil.

• Remove wheel assemblies and lubricate the axle
shafts at least once a season.

TROUBLE SHOOTING
Refer to page 13 of this manual for trouble shooting
information.
ENGINE
Refer to the separate engine manual for all engine
maintenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.
IMPORTANT: Do not attempt to start the engine
when the oil level is inadequate.
Service air cleaner every 25 hours under normal
conditions. Clean after 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
after every 25 hours of engine operation. Spark plug
replacement is recommended at the start of each
season; check engine manual for correct plug type and
gap specifications.
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.
