STARTUP PROCEDURES
Read and understand the starting instructions in the engine
manufacturer’s operation and maintenance manual provided
with this crane.
1. If used, unplug or turn off the engine block heater,
engine oil pan heater, hydraulic tank heaters, and any
other crane heaters.
NOTE Manitowoc recommends the use of the Cold
Weather Package to aid startup when the ambient
temperature will be 0°C (32°F) and below. See Cold
Weather Heaters on page 3-56.
2. Make sure the battery disconnect switch is in the I (on)
position. The engine will not start if the batteries are
disconnected. See Battery Disconnect Switch on
page 3-26.
3. Make sure the emergency stop button on the right
console and on the setup remote control is UP. The
engine will not start if either button is depressed (see
Emergency Stop Button on page 3-14
).
4. Make sure the hydraulic tank shutoff valve is open as
shown in Figure 3-7
.
5. Make sure all crane functions are parked.
The crane is equipped with a hydraulic oil warm-up
circuit. The warm-up circuit is activated only if all crane
functions are parked. The warm-up circuit stays on until
the hydraulic oil temperature reaches 10°C (50°F).
If a function is unparked, the warm-up circuit will
deactivate and remain deactivated until all functions are
again parked and the hydraulic oil temperature drops
below 8°C (46°F).
6. Turn the ignition switch to the RUN position.
• The indicator lights on the RCL/RCI and Main
Displays, the operating limit buzzer, and the system
fault beeper should come on for 2 to 3 seconds
when the ignition switch is in the RUN position; if
not, correct the fault as soon as possible.
• The WAIT TO START icon will appear
in the Crane Operation Status Bar of the
Main Display indicating that the pre-
heater is warming the engine’s air
intake.
The length of time the wait to start icon remains on
depends on ambient temperature. The lower the
ambient temperature, the longer the icon will stay
on.
7. When the WAIT TO START icon turns off, turn the
ignition switch to the START position.
8. Once the engine starts, increase engine speed as
necessary to keep the engine running.
CAUTION
Engine Damage!
To avoid possible engine fault codes and undesirable
operation, make sure the engine ignition switch has been
off five minutes before disconnecting the batteries.
Do not rely on this switch to protect the crane’s electronic
systems when welding. Disconnect the cables at the
batteries before welding
CAUTION
Pump Damage
Do not start the engine until the hydraulic tank shutoff
valve is open. Otherwise, the pumps could cavitate and
be damaged.
CAUTION
Avoid Starter Damage
If the engine does not start after 30 seconds of cranking,
wait a few minutes before starting again so the starter
motor cools.
