OPERATING CONTROLS AND PROCEDURES
3. The WAIT-TO-START lamp is illuminated during the
preheat time that takes place when the IGNITION switch
is in the ON position during cold weather starting. To
minimize cranking time during cold weather starting, the
engine should not be cranked until the WAIT-TO-START
lamp turns off.
4. Turn the IGNITION switch to START and release
immediately when the engine starts. Do not push or hold
the throttle down. The ECM will automatically provide
the proper amount of fuel to start the engine.
5. Immediately check the engine instruments for proper
indication after starting. Shut down the engine if the oil
pressure gauge does not reach the proper reading
within 15 seconds
.
CAUTION
If oil pressure and/or temperature indicator(s) do not
display proper readings, shut down the engine and
correct the malfunction before resuming operation.
6. Allow the engine to warm up at least five minutes before
applying a load. Do not race the engine for a faster warm
up.
Detailed cold weather starting and operating procedures are
covered in the engine manual.
Idling the Engine
Idling the engine unnecessarily for long periods of time
wastes fuel and fouls injector nozzles. Unburned fuel causes
carbon formation, oil dilution, formation of lacquer or gummy
deposits on the valves, pistons, and rings, and rapid
accumulation of sludge in the engine.
NOTE: When prolonged idling is necessary, maintain at
least 800 rpm.
Racing the Engine
NEVER race the engine during the warm-up period. NEVER
operate the engine beyond governed speed (as might occur
in downhill operation or downshifting). Engine bearings,
pistons, and valves may be damaged if these precautions
are not taken.
Shutdown Procedure
1. Allow the engine to operate at idle for about five minutes
to avoid high internal heat rise and allow for heat
dissipation.
2. Turn the ignition switch to OFF.

Crane Travel Operation
Traveling - General
Before traveling, ensure the crane function switch is in the
off position. This will prevent inadvertent operation of
craning functions due to bumping of the controllers while
roading.
RT machines are subject to the same road regulations as
any truck, regarding gross weight, width, and length
limitations.
Although RT machines are specifically designed for rough
terrain, the operator should be extremely cautious and aware
of the terrain in which he is operating.
Do not travel with an empty hook in a position where it can
swing freely.
Do not drive the crane with the lift cylinder bottomed.
Position the boom slightly above horizontal.
Avoid holes, rocks, extremely soft surfaces, and any other
obstacles which might subject the crane to undue
stresses or possible overturn.
Use four-wheel drive only when greater traction is necessary.
(Refer to FOUR-WHEEL DRIVE OPERATION, this section,
for operating instructions.
On open ground, tow or pull only on the tow/tie-down lugs
or with the optional pintle hook.
