steering!
Warnings while driving
If a buzzer tone sounds in the driver's cab, stop
the truck crane immediately and check
whether:
– The permissible lateral tilt (1) of max. 1°
or
– The suspension operation pressure (2) of
210 bar (3,045 psi) has been exceeded.

S
Risk of damage to the steering linkage
The steering linkage can be damaged if the steering wheel is moved while
the vehicle is stationary.
S
Risk of damage to the axle lines!
The suspension struts could be damaged if the maximum permissible
operation pressure in the suspension is exceeded.
Always monitor the operation pressure in the suspension when moving the
rigged truck crane.
G
Danger of overturning by switching on the suspension
Never attempt to level the crane horizontally using the level adjustment
system. The suspension must be deactivated (locked) while the rigged truck
crane is on wheels.
Switching on the suspension would cause the suspension cylinders to be
suddenly pressed together and damaged, and the truck crane could
overturn.
