Not to be used with IIC gases and IIB gases hydrogen sulphide, ethylene oxide and light metal and shock
sensitive dusts!
No use in temperature class T5 or T6.
It is not allowed to use the equipment in area at risk from explosion where gas AND dust does both exist
at the same time!
During assembly and operation of explosion-proof equipment, the relevant regulations of i.e. BG-Chemie
about the use of equipment in area at risk from explosion, must be adhered to by the user/owner.
Please make sure that external ventilation is sufficient.

.
It is not allowed to take off clothes.
The surface temperature of the devices could increase by a variety of external circumstances. For this
reason, the surface temperature is to be monitored.
Avoid ignitable dust deposits.

parts.
Never remove dust with compressed air - remove it with a wet bolt of cloth.
Defective units or units that show abrasion of its surface rust on chains, hooks, or suspension devices,
must be taken out of service.
Please observe the prescribed intervals.
Assembly and maintenance work must only be carried out in an atmosphere not prone to explosion.
Check the grease level of the bearings regularly
Exchange friction surfaces in time and (an exception to this are electric units - maintenance of the brakes
must only be effected by HADEF).
Protect the device from impact, friction, rough handling and moisture.
DANGER!
The operator is responsible for professional equipotential bonding (earthing) for power-operated
