8.  Preventive Maintenance Schedules 

This chapter deals with the recommended preventive maintenance and 
replacement schedules for the Precision Platform 4022 scanner. The 
maintenance of this scanner can be broken down into these areas of the 
scanner: 

•

 

General Scanner Maintenance 

•

 

Air System  

•

 

Fluid Supply System 

•

 

Power Tracks 

•

 

Carriage, Tracks, and Beam Seals 

•

 

Drive Belt System 

•
