b) Drain oil while engine is warm from operation.
c) The oil drain valve is located on right hand side of engine.
Place pan under machine to catch oil. Fit hose in literature pack over oil
drain valve. Rotate valve 1/4 turn counterclockwise and gently pull outward
to open valve. Allow oil to drain, then close valve by pushing inward and
rotating 1/4 turn clockwise. Remove and retain the hose for future use.
d) Replace the oil filter every other oil change. Clean around oil filter and
unscrew filter to remove. Before reinstalling new filter, apply a thin coating of
oil on the surface of the rubber seal. Turn filter clockwise until rubber seal
contacts the filter adapter then tighten filter an additional 2/3 to 3/4 turn.
e) Clean around oil fill cap and remove cap. Fill to specified capacity and replace
cap. Use oil recommended in engine owner’s manual. DO NOT overfill.
f) Start the engine and check for leaks.
4.1.12 Check hydraulic oil level:
Service Interval: 40 hr.
a) Stop engine and wait for all moving parts to stop.
b) Unhook seat latch and tilt seat up.
c) Clean area around hydraulic reservoir cap and remove cap. Oil level should
be to the top of the baffle inside the tank. If not, add oil. Use only Mobil 1
15W-50 synthetic motor oil. Replace hydraulic reservoir cap and tighten
until snug. Do not overtighten.
NOTE: The baffle is labeled “HOT” and “COLD”. The oil level varies with
the temperature of the oil. The “HOT” level shows the level of oil when it is
at 225°F (107°C). The “COLD” level shows the level of the oil when it is at
75°F (24°C). Fill to the appropriate level depending upon the temperature
of the oil. For example: If the oil is about 150° F (65°C), fill to halfway
between the “HOT” and “COLD” levels. If the oil is at room temperature
(about 75° F (24°C)), fill only to the “COLD” level.
4.1.13 Check tire pressures:
Service Interval: 40 hrs.
a) Stop engine, wait for all moving parts to stop, and remove key.
b) Check tire pressure in drive tires.
c) Inflate drive tires to 13 psi (90 kPa).
d) Caster tires do not need to be inflated.
NOTE: Do not add any type of tire liner or foam fill material to the tires.
Excessive loads created by foam filled tires may cause failures to the hydro drive
system, frame, and other components. Foam filling tires will void the warranty.
4.1.14 Check condition of belts:
Service Interval: 40 hrs.
a) Stop engine, wait for all moving parts to stop, and remove key.

deck drive belt.
