When the clutches kick in it will drain the air tank. 

How in the world can I cycle the clutches, either independently or as a set so I can see which one's leaking? Absolutely can no see any place to do it. Using the Manual/Auto feature on the section control does nothing. If I just unplug the compressor I'm going to get constant error messages, and I can't see where I can set it to just do Section control with the drive motors and just not use the tru count. This is rather Frustrating.
