Observe the following safety instructions during all maintenance work on the jib crane:

─     Switch off the mains switch. Secure the switch to ensure it cannot be turned back on accidentally.

─     Unplug the mains disconnector plug from the socket on the crane panel. Secure the socket with a padlock to ensure it is not plugged back in accidentally.

─     Use suitable lifting platforms and fall protection equipment.

─     Adequately cordon off the work area around the lifting platform.

─     Notify personnel in the area that maintenance work will be performed.

─     Only trained electricians should work on the crane electrical system!

─     Even after the emergency stop button has been pressed, life-threatening high voltages are still present in the panels.
