5.3 Driving and turning off the truck crane
5.3.1 Checks while driving
Right after
starting
• Check the service and parking brakes for correct functioning immediately
after starting out.
• Check the lamps (1).
At speeds above 10 km/h (6 mph), all the lamps (1) must go out. If a lamp
does not go out, this indicates a malfunction in the steering.
– The lamp (1) lights up when an error is detected in the steering system –
the symbol (2) is shown. The 5th and 6th axles are brought into the
straight running position and can no longer be steered. It is possible to
continue driving. Steering is now only possible with the 1st and 2nd axle
lines – the turning radius increases accordingly.
• Have the error resolved as soon as possible.
– The lamp (1) lights up when a severe error is detected in the steering sys-
tem – the symbol (2) is shown. The 5th and 6th axle lines can longer be
steered in a controlled manner.
• Stop the vehicle as soon as possible. Briefly turn off the ignition and
then on again. If the lamp is still lit, contact Manitowoc Crane Care.

G
Risk of accident by out-of-control truck crane
Never switch off the ignition or remove the ignition key while the truck
crane is moving!
In this way you prevent the steering from locking and do not lose control of
the moving truck crane.
G
Risk of accident when the ignition is switched off
Never switch off the ignition while driving.
After switching off the ignition the 5th and 6th axle lines are brought into
forward alignment and can no longer be moved.
This changes the turning radius of the truck crane.
