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
o
F.
Lubrication
(Refer to Lubrication Chart in Figure 15.)
WARNING: Always stop engine and
disconnect spark plug wire before
cleaning, lubricating or doing any kind of
work on lawn mower.
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
you disassemble the transmission for any reason,
refill with two ounces of Alvania grease (part # 737-
0168) as part of reassembly.
Engine
•
Follow engine manual for instruction and schedule
of lubrication.
NOTE: When tipping the unit, empty the fuel tank and
keep engine spark plug side up.

Blade Care
•
Periodically inspect the blade adapter and pulley
for cracks, especially if you strike a foreign object.
Replace when necessary.
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.
•
Disconnect spark plug wire from spark plug.
To Remove Blade
•
Remove the bolt and bell washer which hold the
blade-pulley assembly to the engine crankshaft.
See Figure 16. Remove assembly from crankshaft.
•
Remove the two bolts and lock nuts from the blade
assembly.
•
Remove the blade from the blade adapter and
pulley.
To Replace Blade:
•
Before reinstalling the blade-pulley assembly to the
unit, lubricate engine crankshaft and inner surface
of the blade adapter with light oil or engine oil.
