Engine
A list of key maintenance jobs required for good
performance by the mower is given below. Follow the
accompanying engine manual for detailed list and
instructions.
•
Change engine oil after the first two operating
hours and every 25 operating hours thereafter.
Always check oil level before starting engine.
•
Clean the engine periodically. Remove dirt and
debris with a cloth or brush. 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 spark plug and reset the gap to .030" at
least once a season or every 50 hours of operation.
Spark plug replacement is recommended at the
start of each season. Refer to the engine manual
for correct spark plug type.
•
Inspect muffler periodically, and replace if
necessary. Damaged mufflers or spark arresters
can create a fire hazard.
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
Lubrication

Blade Control
•
Lubricate the pivot points on the blade control
handle and the brake cable at least once a season
with light oil. The blade control must operate freely
in both directions.
Rear & Side Discharge Doors
•
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.
Transmission
•
The transmission is pre-lubricated and sealed at
the factory and does not require lubrication on a
regular basis as part of maintenance. However, if
