chain hoist must be overhauled by the manufacturer.
Components being in the power flux may only be overhauled by the
manufacturer or his authorised partners.

What is to be done if....?
6.11.1 Chain hoist does not work
Chain hoist is switched off. Switch on.
Temperature control (if existent) has reacted. Allow to cool off.
Emergency stop activated. Release emergency stop.
Fuse triggered. Fit new fuse or switch on automatic circuit braker.
Power supply interrupted.
Reconnect power supply.
6.11.2 Heavy loads can no longer be lifted
Overload. Reduce load.
Slipping clutch is incorrectly set or worn.
Adjust slipping clutch if nominal load is no longer lifted
(see Adjusting slipping clutch).
6.11.3 Slippage of load more then 10 cm
Brake lining worn.
Adjust brake, if necessary replace brake disc.
6.11.4 Direction of motion does not correspond to symbols on control
pendant
Power supply wrongly connected. Interchange 2 phases of power supply.
6.11.5 Loud noises when loads are lifted or lowered
Chain worn. Replace load chain
