11.  Remove the screws and remove the motor from the flange 
 

The installation takes place exactly in the reverse order! 

Tightening torque: 15 Nm 

 

 

After installing, check whether the toothed belt is sufficiently 
tensioned! 

 

 

Toothed belt 

 

  CAUTION 

Injuries can arise if fingers, hair or articles of clothing get caught 
between the toothed belt and the drive wheel or toothed wheel. 

►  All work must be carried out only by trained personnel. 

 

The toothed belt is exposed to high loads during operation and must 
therefore be checked regularly: 

– 

Check the toothed belt every six months for wear and tension 
according to the maintenance schedule. Powder deposits should be 
preferably removed with a vacuum cleaner, because this can 
influence the quiet running and shorten the service life of the toothed 
belt 

– 

Switch on the gun axis and check the carriage for quiet running. 
Check the toothed belt for elongation or wear (noisy running, or 
similar) 

Replacing the toothed belt 

Procedure:

1. 

Switch off the power supply.  

2. 

Remove the protective cover
