Observe the following safety instructions for any maintenance work on the chain hoist:

─     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 operating range around the lifting platform.

─     Switch off any other cranes using the same crane track or cranes working above or below the crane undergoing maintenance. Secure the switches to ensure they cannot be turned back on accidentally. Otherwise, other cranes could overturn the hoisting platform or crash into the crane undergoing maintenance.

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

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

─     Even after pressing the emergency stop button, life-threatening high voltages are still present in the chain hoist.
