season with light oil. See Figure 9. The blade control must operate freely in both directions.

removed for any reason, lubricate the surface of the axle bolt and the inner surface of the wheel with light oil.

SECTION 9: MAINTENANCE
WARNING: Be sure to disconnect and ground the spark plug wire before performing any repairs
or maintenance.
NOTE: When tipping the unit, empty the fuel tank and keep engine, spark plug side 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. Read and follow
instructions carefully.
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 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.
