To ensure safe operation of your unit, all nuts and bolts must
be checked periodically for correct tightness.
DECK
The underside of the mower deck should be cleaned after
each use to prevent a buildup of grass clippings, leaves, dirt
or other matter. If this debris is allowed to accumulate, it wilt
invite rust and corrosion, and may cause an uneven dis­
charge of grass clippings at the next cutting.
The deck may be cleaned by tilting the mower and scraping
clean with a suitable tool (make certain the spark plug wire is
disconnected).
ENGINE
Refer to the separate engine manual for engine mainte­
nance instructions.
Maintain engine oil as instructed in the separate engine
manual packed with your unit. Read and follow instructions
carefully.
Service air cleaner every 25 hours under norma! 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 separate engine manual packed with your unit.
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 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 grass, dirt and combustible
debris from muffler area.
OFF-SEASON STORAGE
The following steps should be taken to prepare lawn mower
for storage.
1. Clean and lubricate mower thoroughly as described in
the lubrication instructions.
2. Refer to engine manual for correct engine storage
instructions.
3. Coat mower’s cutting blade with chassis grease to
prevent rusting.
4. 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.
