performance and flooding usually indicates that the
air cleaner should be serviced. To service the air
cleaner, refer to the engine manual.
•
The spark plug should be cleaned and the gap
reset once a season. Spark plug replacement is
recommended at the start of each mowing season;
check engine manual for correct plug type and gap
specifications.
•
Clean engine regularly with a cloth or brush. Keep
the cooling system (blower housing area) cleaned
to permit proper air circulation which is essential to
engine performance and life. Make sure to remove
all grass, dirt and combustible debris from muffler
area.
SECTION 8: OFF-SEASON STORAGE
The following steps should be taken to prepare lawn
mower for storage.
•
Clean and lubricate mower thoroughly as described
in the lubrication instructions.
NOTE:
We do not recommend the use of pressure
washers or garden hose to clean your unit. They may
cause damage to electric components, spindles,
pulleys, bearings or the engine. The use of water will
result in shortened life and reduce serviceability.
•
Refer to engine manual for correct engine storage
instructions.
•
Coat mower’s cutting blade with chassis grease to
prevent rusting.
•
Store mower in a dry, clean 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 rust-proof the equipment. Using a light oil or
silicone, coat the lawn mower, especially cables and all
moving parts, before storing it for the off-season.
