Pressure Relief Procedure

WARNING

INJECTION HAZARD

Fluid under high pressure can be in- jected through the skin and cause serious injury. To reduce the risk of an

injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:

Dare instructed to relieve the pressure,

Dstop spraying,

Dcheck or service any of the system equipment,

Dor install or clean the spray tips.

1.Engage the spray gun safety latch.

2.Close the bleed-type master air valve (supplied in your system).

3.Shut off the air regulators.

4.Disengage the spray gun safety latch.

5.Hold a metal part of the spray gun firmly to the side of a grounded metal pail, and trigger the spray gun to relieve pressure.

6.Engage the spray gun safety latch.

7.Open the drain valve (supplied in your system), having a container ready to catch the drainage.

8.Leave the drain valve open until you are ready to spray again.

If you suspect that the spray tip or hose is completely 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. Now clear the tip or hose.

Flush the Pump Before Using

Pumps are tested with lightweight oil which is left in to protect the pump parts. To prevent contamination of the fluid, flush the pump with a compatible solvent before using it.

WARNING

Before flushing, be sure the entire system and flushing pails are properly grounded. Refer to Grounding on page 5. Follow the Pressure Relief Procedure at left, and remove the spray tip from the gun. Always use the lowest possible fluid pressure, and maintain firm metal-to-metal contact between the gun and the pail during flushing to reduce the risk of fluid injection, static sparking, and splashing in the eyes or on the skin.
