7. Open the Pump Bleed Valve (AM). Have a container
ready to catch the drainage.
8. Leave the Pump Bleed Valve (AM) open until ready
to dispense again.
9. If you suspect the dispense valve is clogged or that
pressure has not been fully relieved:
a. VERY SLOWLY loosen the hose end coupling
to relieve pressure gradually.
b. Loosen the coupling completely.
c. Clear the obstruction in the tip/nozzle of the
valve.
10. Close the Main Air Slider Valve (BA).
11. Set the Ram Director Valve (BC) to DOWN. The
Ram (AA) will slowly drop.
12. Once the Ram (AA) is completely down, jog the
Ram Director Valve (BC) up and down to bleed air
from the Ram (AA) cylinders.
