Engine
Some general recommendations for maintaining the
engine are listed below. Refer to the separate engine
manual for more details about engine maintenance.
•
Maintain engine oil as instructed in the engine
manual. Read and follow instructions carefully.
IMPORTANT:
Do not attempt to start the engine when
the oil level is inadequate.
•
Service air cleaner every ten hours under normal
conditions. Clean after every hour of operation
under extremely dusty conditions. Poor engine
performance and flooding usually indicates that the
air cleaner should be serviced.
IMPORTANT:
Never run your engine without air cleaner
completely assembled.
•
Clean spark plug and reset the gap every 25 hours
of engine operation. Spark plug replacement is
recommended at the start of each season. Refer to
the engine manual for plug type and gap specs.
Cleaning
•
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.
•
Clean the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area)
clean for proper air circulation. Be certain to remove
all dirt and combustible debris from muffler area.
NOTE: We do not recommend the use of pressure
washers to clean your unit. Pressure washing may
cause damage to electric components, spindles,
pulleys, bearings or the engine, thus reducing life and
serviceability of your equipment.
SECTION 7: OFF-SEASON STORAGE
If the tiller will not be used for a period longer than 30
days, the following steps should be taken to prepare the
tiller for storage.
•
Clean the exterior of engine and the entire tiller
thoroughly. Lubricate the tiller as described in the
lubrication instructions.
•
Refer to the engine manual for correct engine
storage instructions.
•
Wipe tines with oiled rag to prevent rust.
•
Store tiller in a clean, dry area. Do not store next to
corrosive materials, such as fertilizer.
NOTE: When storing any type of power equipment in
an unventilated or metal storage shed, care should be
taken to rustproof the equipment. Using a light oil or
silicone, coat the equipment and especially any
springs, bearings, and cables.
