 MAINTENANCE 

Scheduled maintenance for the VTS is not required; however each AccuStation does include an 
access cover which can be removed to inspect the airflow sensors if desired. 

8.1 Round Station Access Cover 

CAUTION:

 Wear eye protection, cut-resistant gloves and clothing suitable for working 

with sheet metal.  Failure to do so may result in personal injury.

possibly causing injury. 

 
8.1.2 Using two hands; squeeze 
the access cover and slide it 
forward over the station enough 
to uncover the access opening. 
 
8.1.3 Once the cover is slid 
forward or removed, the airflow 
sensors can be visually inspected. 
 
8.1.4 When inspection is 
complete, slide the access cover 
over the opening, being careful not to damage gasket in the process.
