4.1.11 Check hydraulic oil level:
Service Interval: 40 hr.
a) Stop engine and wait for all moving parts to stop.
b) Clean area around hydraulic reservoir cap and remove cap.
c) 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.
4.1.12 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 all four tires.
c) Inflate caster tires to 16 psi (1100 kPa).
d) Inflate drive 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.
