5.2.5 Starting
To start moving you must do the following:
– shift into a gear,
– press the accelerator,
– release the parking brake
When starting, the wet clutch is filled with oil and the truck crane starts driv-
ing. After starting the indicator lamp goes out (1) and the driving force is
then transmitted via the dry clutch.
Warning when starting
When the load during starting is so large that it would cause the clutch to
overheat, a warning buzzer sounds. A corresponding messages is also
shown on the display of the on-board computer (1).
• In this event immediately take your foot off the accelerator and apply the
service brake.
• Switch to the neutral position N and leave the engine running until the
clutch has cooled down and the symbol (1) is no longer shown on the
display.
• Select a lower starting gear.
• Start to move again.

Risk posed by unexpected rolling!
Also apply the parking brake before starting on sloping ground. The gear
will be engaged only once you depress the accelerator. This can lead to the
truck crane starting to move (perhaps backwards) whilst you are moving
your foot from the brake pedal to the accelerator.
