OPERATING CONTROLS AND PROCEDURES

RCL Override

If the RCL is overridden, the crane operation is not monitored
and the switched off crane movements are enabled again.
Tipping and/or Machine Damage Hazard!
You may only override the RCL if it becomes absolutely
necessary in the event of an emergency. This is to put the
crane into a safe condition in the event of a malfunction. In
this case, do not perform any movements that would
increase the load moment.
