If an unexpected hazardous situation occurs during crane operation,
release all of the operating levers immediately and press the emergency

guaranteed.
Every time before starting work a check of the Emergency Off function must be carried out:
• Operate a crane function and press the Emergency Off switch. The crane must immediately come
to a standstill.

If the crane's movement is not interrupted, crane operation must be
ceased immediately and a service workshop visited!
