Freeing truck crane stuck in terrain

If the truck crane is stuck in terrain, you can try to free it by driving back and
forth (rocking it free):
When rocking free, you should
– switch on the transverse differential locks,
– switch on the longitudinal differential locks,
– switch to the P driving mode and
– switch on the off-road gear in the transfer case.
Risk of damage to the transmission!
Release the accelerator after 30 seconds at the latest when the load is too
high.
This prevents the transmission from being damaged due to overheating.
The starting gear is not automatically disengaged.
•
Let the motor run at idling speed.
•
Select a gear position, e.g. gear position R.
•
Drive as far as you can as high as possible.
•
Remove your foot from the accelerator and switch to the neutral position.
•
Let the truck crane roll in the opposite direction.
•
Before you reach the highest point, select the gear position again,
e.g. gear position R.
•
Drive as far as possible until you reach the highest point, and repeat the
procedure.
