b) Fill radiator with a 50/50 mix of water and Dex-Cool© coolant (as specified
in Section 2.5.2), allowing some room (approximately 1/2" (12.7 mm)) for
expansion. Add 50/50 coolant mix to overflow bottle on the left side of the
engine as required to bring the level up to the indicator line on the bottle.
POTENTIAL HAZARD
♦ Engine compartment contains open belt drives and fans.
♦ Rotating components can cause injury
WHAT CAN HAPPEN
♦ Fingers, hands, loose clothing, or jewelry can get caught
by the rotating fan and drive shaft.
HOW TO AVOID THE HAZARD
♦ Do not operate machine without the covers in place.
♦ Keep fingers, hands, and clothing clear of rotating
components.
♦ Shut off engine, remove key, and wait for moving parts
to stop before performing maintenance.
e) With the cap off the radiator, tilt hood closed and put the seat down. Start
the engine. Refer to Section 4.3.2. Return the seat up and hood forward
to the open position.
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.
5.1.13 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.
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 13 psi (90 kPa).
For units with Pneumatic Caster tires (with a valve stem):
