5.1.13 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. 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 has two levels. The upper level represents the “HOT”
level and the lower level represents the “COLD” level. The oil level varies
with the temperature of the oil. The “HOT” level shows the level of oil when it
is a 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.
5.1.14 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 10 psi (69 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.
