10.2  Replacing the toothed belt 

 

 

For optimum functioning of the linear unit and to prevent damage 
during operation, it must be ensured during assembly that no 
foreign matter enters any parts of the linear unit. 

 

 

Do not damage the standard parts (screws, pins, etc.) as they will 
be used again.
