5.2.9 DM and RM transmission mode
The DM and RM transmission modes are intended for manoeuvring the
vehicle without changing gears, e.g. for moving the truck crane while
loaded. In these transmission modes, only the 4th and 5th axles are
(hydraulically) driven.
You can restrict the maximum speed.
Switching on
• Stop the truck crane and release the accelerator.
• Wait until the engine runs at idle speed.
• Shift into DM or RM position for the required direction of travel.
The appropriate transmission mode is selected and appears on the display.
In the transmission modes DM and RM:
– The transmission does not shift
– Manual gear shifting is not possible
• Press the brake pedal.
