f) Operate engine until the engine thermostat opens and coolant is circulating
through the radiator core. As air is purged from the engine block and the
coolant level drops, add additional coolant to the radiator.
g) When the radiator is completely full and no additional coolant can be
added, continue running and install the radiator cap. Make sure that the
cap is completely seated by pressing down firmly while turning until the cap
stops. Once the cap is installed, the engine may be stopped.
Check hydraulic oil level:
Service Interval: 40 hr.
a) Stop engine and wait for all moving parts to stop.
b) 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.
Check tire pressures:
Service Interval: 40 hrs.
a) Stop engine, wait for all moving parts to stop, and remove key.
b) Inflate all four tires to 13 psi (90 kPa).
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.
Check condition of belts:
Service Interval: 40 hrs.
a) Stop engine, wait for all moving parts to stop, and remove key.
b) Tilt seat up. Lift the rubber flap on front side of the engine to check pump
drive belt.
c) Remove left and right belt shields on deck and lift up floor pan to inspect
deck drive belt.
d) Check under machine to inspect the mule drive belt.
e) See Sections 5.2.3, through 5.2.5 for belt adjustment.

a) Stop engine, wait for all moving parts to stop, and remove key.

gun grease.
