□ Open the ball valve on the test tool and observe the engine
tachometer. Engine speed should increase to about 1,800 to
2,200 RPM.
□ Close the air valve slowly to allow the system pressure to rise.
□ Once the system pressure is at maximum, slowly open the ball
valve on the test tool until the pressure on the gauge begins to
drop. Engine speed should start to ramp-up when air pressure
drops to approximately 140 psi.

If you intend to use an auxiliary air receiver with this system
you must observe the following installation procedure to
prevent damage to the system.
The line to the auxiliary tank must not be installed in the bottom of
the tank, but must be installed as high as possible to prevent water
from entering the line.
