  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. 

  Please wear conductive shoes. Gloves should have a shunt resistance of < 10

8

  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. 

  Remove dust deposits daily before commencing work and ensure that dust cannot settle between moving 

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. 

 

Special scope 

Use of different EX-zones is depended from the EX-classification of the unit. Find the EX-classification on its 
type plate.
