Note:
This cool down period is very important for a crane with a turbocharged engine. This
is because the turbocharged engine makes more heat than an engine that does not
have a turbocharger.
If more data about the engine is necessary, look in the technical documents for
engine.
7.4 COLD WEATHER STARTING
If you operate the crane in very low temperature areas, the engine is hard to start. The
optional flame starting device is very important for the normal engine start. Please speak
with the Zoomlion Service Department if you select a flame starting device for your crane.
7.5 MOVE AND PARK THE CRANE
7.5.1 MOVE THE CRANE
WARNING
Make sure that the crane has sufficient brake pressure before you try to move the
crane. A dangerous condition occurs if the crane starts to move and you cannot
stop it.
After you prepare the crane for driving, use the steps below to start the vehicle:
A. Depress the brake pedal.
B. Deactivate the park brake.
C. Move the gear selector to the “F1” position.
D. Release the brake pedal gradually and start to drive.
7.5.2 PARK THE CRANE
A. Gradually push the brake pedal and move the gear selector to the “F1” position.
B. When the crane is at a slow speed, push the brake pedal to stop the crane.
C. Turn the park brake switch to the “P” position and move the gear selector to the “N”
position.
CAUTION
When the crane is in the “Crab steer” or “4-wheel steer” mode, make sure that
you center the axles before you stop.
D. When it is necessary to stop the engine, operate the engine at idle speed (with no
load on the engine) for minimum of 5 minutes. This lets the engine coolant
temperature decrease gradually before the engine stops.
E. Do not turn the ignition switch to the “0” position at this time. Stop the engine and keep
