Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This procedure describes how to relieve pressure for the
supply system. Use this procedure whenever you shut
off the system and before checking or adjusting any part
of the system.
1. Lock the gun/dispense valve trigger.
2. Turn the ADM off by pressing the On/Off key
.
3. Close the air motor ball valve (BF) and the main air
ball valve (BA) on the ram(s).
4. Set the ram director valve (BC) to the DOWN posi-
tion. The ram will slowly drop.
5. After the ram reaches the bottom, jog the director
valve (BC) up and down to bleed air from the ram
cylinders.
6. Unlock the gun/dispense valve trigger.
7. Hold a metal part of the dispense valve firmly to the
side of a grounded metal pail, and trigger the
gun/dispense valve to relieve pressure.
8. Lock the gun/dispense valve trigger.
9. Open the bleed valve (K). Have a container ready to
catch the drainage. Leave the bleed valve open until
ready to dispense again.
If you suspect the dispense 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 or hose end coupling
and relieve pressure gradually, then loosen completely.
Then clear the tip/nozzle or hose.
Trigger Lock
Always engage the trigger lock when you stop dispens-
ing to prevent the gun from being triggered accidentally
by hand or if dropped or bumped.
Start and Adjust Ram
To start and adjust the ram(s), follow the
procedure on page 17.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief Pro-
cedure when you stop spraying and before cleaning,
checking, or servicing the equipment.

Moving parts can pinch or amputate fingers. When
the pump is operating and when raising or lowering
the ram, keep fingers and hands away from the pump
intake, platen, and lip of the drum.
