Maintaining  the coupling 

 

DANGER 

Risk  of explosion when operating the coupling in potentially 
explosive  atmospheres. 

Risk  of explosion with fatal injuries. 

 

Exclusively use couplings bearing the corresponding ATEX 
marking in potentially explosive atmospheres. 

 

In this respect, read and follow the additional notes in the 
supplementary manual  for ATEX operation. 

  

 

CAUTION 

Risk  of burns from hot surfaces 

 

Shut  the system off before servicing, maintaining or repairing 
the coupling. 

 

Allow the components to cool. 

 

Wear protective gloves when working on the  coupling. 

  

 

CAUTION!

 

Malfunctions and damage to the coupling as a result of 
material fatigue and wear. 

 

Replace aluminium  coupling flanges at least every 10 years. 

  

Preparing for maintenance work 

 

Obtain the  work clearance  permit from the responsible person prior to all work on 
and with the  coupling. 

 

Switch  the drive unit  off. 

 

Secure  the drive unit to prevent reactivation. 

 

Post up a caution  sign indicating that work is in progress. 

 

Wear the  personal protective equipment specified by the owner. 

  

  To handle the  coupling, follow the instructions on page 23.
