Pressure Relief Procedure

SKIN INJECTION HAZARD

System pressure must be manually relieved to prevent system from starting or spraying accidentally. Fluid under high pressure can be injected through skin and cause serious injury. To reduce risk of injury from injection, splashing fluid, or moving parts, follow Pressure Relief Procedure whenever you:

•are instructed to relieve pressure

•stop spraying

•check or service any system equipment

•install or clean spray tip

1.Turn pressure control knob to zero.

2.Turn ON/OFF switch to OFF.

3.Unplug power supply cord.

4.Hold metal part of gun firmly to grounded metal pail. Trigger gun to relieve pressure.

5.Lock gun safety latch.

6.Open prime valve. Leave prime valve open until ready to spray again.

If suspected that spray tip or hose is completely clogged, or that pressure has not been fully relieved after following steps above, VERY SLOWLY loosen tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Then clear tip or hose obstruction.

To reduce risk of pressure control malfunction:

•Use needle-nose pliers to disconnect wire. Never pull on wire, pull on connector.

•Mate wire connectors properly. Center flat blade of insulated male connector in female connector.

•Route wires carefully to avoid interference with other connections of pressure control. Do not pinch wires between cover and control box.
