g) When the radiator is completely full and no additional coolant can be
added, continue running the engine 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.
5.1.12 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. Check
hydraulic reservoir and if necessary fill the reservoir to the appropriate level
with 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.
POTENTIAL HAZARD
♦ Hydraulic fluid escaping under pressure can penetrate
skin and cause injury.
WHAT CAN HAPPEN
♦ Fluid accidentally injected into the skin must be
surgically removed within a few hours by a doctor
familiar with this form of injury or gangrene may result.
HOW TO AVOID THE HAZARD
♦ Make sure all hydraulic fluid hoses and lines are in
good condition an all hydraulic connections and fittings
are tight before applying pressure to hydraulic system.
♦ Keep body and hands away from pinhole leaks or
nozzles that eject high pressure hydraulic fluid.
♦ Use cardboard or paper, not your hands, to find
hydraulic leaks.
♦ Safely relieve all pressure in the hydraulic system, by
placing the motion control levers in neutral and
shutting off the engine, before performing any work on
the hydraulic system.
5.1.13 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.
5.1.14 Check condition of belts:
Service Interval: 40 hrs.
a) Stop engine, wait for all moving parts to stop, and remove key.
