message (2) is displayed.
– The crane movements are enabled.
– If you do not trigger a control lever move-
ment within 10 seconds after the override,
you must press the button (1) again.
– The speed of the movements which
increase the load moment is reduced
to 15%.

Risk of accidents due to overridden or faulty RCL
It is not permitted to work with an overridden or faulty RCL.
Set down the load immediately and stop operating the crane if the RCL is
faulty.
You may override the RCL only if it becomes absolutely necessary to do so
in the event of an emergency. This is to put the truck crane into a safe state
in the event of a malfunction. In this case, do not perform any movements
that would increase the load moment.
