10.2  Replacing the timing belt 

 

 

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 cover 
band and its elements; they will be re-used. 

 

Risk of damage due to lack of lubrication!  
Do not lose or damage the O-rings fitted on the lubricating apertures, 
otherwise component lubrication will not be guaranteed.
