1.

2.
Integrated Air Controls:

Close the air motor slider valve and the main air
slider valve.

Set the ram director valve to DOWN. The ram

from ram cylinders.
3.
Standard Air Controls:
a.
Close the air motor valve and the main air bleed
valve.

Move the ram director valve to DOWN until all
air is exhausted from one cylinder.
c.
Move the director valve to UP until all air is
exhausted from the other cylinder.
4.
Unlock the gun/valve trigger.
5.
Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
6.
Lock the gun/valve trigger.
7.
Open the fluid line drain valve and the pump bleed
valve (P). Have a container ready to catch the drain-
age.
8.
Leave the pump bleed valve open until ready to
spray again.
If you suspect that the spray tip/nozzle or hose is com-
pletely clogged, or that pressure has not been fully
relieved after following the steps above, very slowly
loosen the tip guard retaining nut, nozzle, or hose end
coupling and relieve pressure gradually, then loosen
completely. Now clear the tip/nozzle or hose.
