5.3 Driving the truck crane and switching it off
5.3.1 Checks whilst driving
Immediately after
you start to move
• 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. Only the 1st and 2nd axle lines are still available for
steering – the turning circle increases in size accordingly.
• Have the error rectified as soon as possible.
– The lamp (1) lights up when a serious fault is detected in the steering sys-
tem – the symbol (2) is shown. The 5th and 6th axle lines can no longer be
steered in a controlled manner.
• Stop the vehicle as soon as possible. Briefly switch the ignition off then
on again. If the lamp is still lit, contact Manitowoc Crane Care.

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!
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 the ignition is switched off, the 5th and 6th axle lines are brought into
the straight-ahead position, and can no longer be steered.
This changes the turning radius of the truck crane.
