REMOVING EXCESS AIR (VACUUM) FROM THE HYDRAULIC SYSTEM
1. Pump the jack completely up and continue to pump the pedal after the jack reaches the top. This will
force the air through the system and the jack should now pump up.
JACK DESCENT RATE ADJUSTMENT
1. Pump the jack up to full height.
2. The descent rate butterfly valve is located on the manifold assembly. Reach under the base hood and
turn the valve clockwise to decrease the rate of descent. Turn it counterclockwise to increase the rate
of descent.
