10.3  Replacing cover bands 

 

 

To preserve the optimum running of the linear unit and prevent it 
from being damaged during operation, take care that no foreign 
bodies penetrate the base profile or other linear unit components 
during installation and assembly. 

 

 

Do not damage the standard parts (screws, pins, etc.) or the 
dismantled components; they will be refitted. 

 

 

If cover bands are worn, also replace the band guide elements.  
If cover bands are damaged, check the band guide elements for 
wear and replace them only as necessary.
