the factory and does not require lubrication on a
regular basis as part of maintenance. However, if
you disassemble the transmission for any reason,
refill with two ounces of Alvania grease (part # 737-
0168) as part of reassembly.

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 will invite rust and corrosion, and may
prevent proper mulching, discharge, or bagging. The
deck may be cleaned by tilting the mower and scraping
clean with a suitable tool (make certain the spark plug
wire is disconnected).
We do not recommend the use of a
IMPORTANT:
pressure washer or garden hose to clean your unit.
NOTE: When tipping the unit, empty the fuel tank and
keep the spark plug side of engine up. Never tip the
mower more than 90 degrees and do not leave the
mower tipped for any length of time. Oil can drain into
the upper part of the engine causing a starting problem.
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.
• Service air cleaner every 25 hours under normal
conditions. Poor engine performance and flooding
usually indicate 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.
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.
WARNING: Make sure to avoid muffler and
surrounding areas while the mower engine is
hot because temperature of these areas of
the engine may exceed 150
Blade Care
WARNING: When removing the cutting blade
for sharpening or replacement, protect hands
by using heavy gloves or a thick rag to grasp
the cutting blade.

adapter and pulley for cracks, especially if you
strike a foreign
necessary.
