Engine
A list of key engine maintenance jobs required for good
performance by the mower is given below. Follow the
accompanying engine manual for detailed list and
instructions.
Maintain engine oil level as instructed in 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. Remove all grass, dirt
and combustible debris from muffler area.
Lubrication
Blade Control
Lubricate the pivot points on the blade control handle
and the brake cable at least once a season with light oil.
See Figure 20. The blade control must operate freely in
both directions.
Rear Discharge Door
The torsion springs and pivot points should be
lubricated periodically with light oil to prevent any rust
or binding. Door must work freely.
Wheels:
The wheels require no lubrication. However, if the
wheels are removed for any reason, lubricate the
surface of the axle bolt and the inner surface of the
wheel with light oil. Engine oil may also be used.

Follow engine manual for lubrication instructions.
