5.3 Driving the truck crane and switching it off
5.3.1 Checks whilst driving
Brakes • Check the service and parking brakes for correct functioning immediately
after starting out. Only continue the drive when the brakes are working
perfectly.
ABS system
• Check the lamps (1).
At speeds of above 6 km/h (4 mph), the lamps (1) must go out. Then the Anti
Blocking System (ABS) is operational and the wheels are prevented from
being blocked when you brake.
If a lamp does not go out, the corresponding ABS system is faulty, and the
wheels will no longer be prevented from blocking. The full braking force
remains intact;
à Malfunctions of the service brake, p. 8 - 25.
If the lamp (1) lights up, then the braking process is supported by the ABS
system.

G
Risk of accidents because the truck crane cannot be steered
Never switch off the ignition or remove the ignition key while the truck
crane is moving
This precaution prevents the steering locking and consequent loss of con-
trol of the moving truck crane.
G
Risk of accident when the ignition is switched off
Never switch off the ignition while driving.
Once the ignition is switched off, the 4th axle line is brought into the
straight-ahead position, and can no longer be steered.
This changes the turning radius of the truck crane.
