Maintaining the fine mesh filter 

Observe the following cleaning instructions: 

 

Before assembly, all parts must be cleaned in order to remove any foreign particles 
(swarf) and soiling. 

 

If screws, bolts, or washers are replaced with identical new parts, any oil on these new 
parts must first be removed. 

 

Observe the tightening torques below when following the instructions in this section:
