3. Turn the Engine Run/Stop/Run key switch to RUN.
NOTE: The operating limit alert and the system fault alert
(lights, buzzer, beeper) should come on for three
seconds when the Engine Run/Stop/Run key
switch is moved to the proper RUN position. If not,
replace worn parts.
4. If required, disengage the pump drive (Figure 3-15
).
This step will disconnect the pumps from the engine and
aid in cold weather startup.
5. Turn the Engine Start switch to start the engine.
NOTE: The engine has an ether starting aid, which the
engine’s computer activates automatically when
needed. There is no need to manually spray ether
into the engine during cold weather starts.
6. Increase the engine speed as necessary to keep the
engine running after it starts.
7. If disengaged, engage the pump drive within two
minutes after starting the engine.
8. Run the engine at low idle until the hydraulic oil
temperature is at least 16°C (60°F).
NOTE: It is normal for the System Fault alert to remain on
after the engine is started. The alert should go off
as soon as engine oil pressure and hydraulic oil
temperature rise to normal (if no other faults exist).
9. Confirm the crane mode in effect or select and confirm
another crane mode. The drums and boom hoist are
inoperable until this step is performed (the operating
limit alert will come on, and CONFIRM MODE will
appear on the digital display if operation is attempted).
CAUTION
Avoid Pump Drive Damage!
Observe the following precautions when equipped with a
pump drive disconnect:
• Use the pump drive disconnect only as a starting aid
during cold weather (0°C [32°F] or below).
• Stop the engine before engaging or disengaging the
pump drive.
• Do not run the engine longer than two minutes with
the pump drive disconnected.
CAUTION
Avoid Starter Motor Damage!
Do not crank the starter motor for more than 30 seconds.
If the engine does not start after 30 seconds of cranking,
wait a few minutes for the starter motor to cool.

CAUTION
Avoid Machinery Damage!
Do not operate the crane when the System Fault alert is
on. If the alert does not go off soon after the engine is
started or comes on during operation, immediately
proceed as follows:
• Determine the fault on the digital display.
• Land loads if possible. Otherwise, turn on the drum
park to apply the drum brake and engage the drum
pawl (if equipped).
• Move all control handles to OFF.
• Stop the engine.
• Correct the cause of the fault.
CAUTION
Avoid Machinery Damage!
Continuous operation with hydraulic oil temperature
above 82°C (180°F) can result in damage to hydraulic
components. Troubleshoot the hydraulic system if the oil
temperature exceeds 82°C (180°F).
