Maintaining the Deck
NOTE: We do not recommend the use of pressure
washers or garden hose to clean your unit.These may
cause damage to electric components spindles,
pulleys, bearings or the engine. The use of water will
shorten life of the mower and reduce its serviceability.
Clean the underside of the mower deck after each
use to prevent a buildup of grass clippings, leaves,
dirt or other matter. If this debris is allowed to
accumulate, it will result in rust and corrosion, and
may cause an uneven discharge of grass clippings
during the next cutting. Tilt the mower and scrape
clean with a suitable tool.
WARNING: Remember to disconnect the
spark plug wire before tilting the mower.
Engine
Refer to the separate engine manual for engine
maintenance instructions.
Maintain engine oil level as instructed in the engine
manual.
Service air cleaner every 25 hours under normal
conditions. Clean every few hours 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
engine manual.
Clean spark plug and reset the gap 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) clean 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.
Replacing Rear Flap
The rear flap is attached to the back of the mower deck,
and is designed to minimize the possibility of objects
being thrown from the rear of the mower toward the
operator. If the rear flap becomes damaged, replace as
follows:
To remove the old rear flap, cut off the flat end of
the wire rod which secures it to the deck using a
pair of side-cutters. Attach the new rear flap using
the new rod provided with the rear flap, bending the
ends of the rod over to secure.
SECTION 8: OFF-SEASON STORAGE
If the lawn mower is not going to be used for 30 days or
longer, prepare the unit for storage. Follow the steps
below for proper storage of the mower.
Clean and lubricate mower thoroughly as described
in the lubrication instructions.
Refer to engine manual for correct engine storage
instructions.
Coat mowers 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 equipment, especially cables and all
moving parts.
