Operation

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.Lock the spray gun trigger safety.

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

3.Shut off the air regulators.

4.Unlock the spray gun trigger safety.

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.Lock the spray gun trigger safety.

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.

WARNING

For your safety, before operating the equipment be sure all operators have read and fully understand all the warnings, cautions, and instructions in this manual and all manuals supplied with each compo- nent or accessory.

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.

Starting and Adjusting the Pump

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8.

See Fig. 4. Be sure the air regulators (10a and 10b) and bleed-type master air valve (16) are closed. Do not install the spray tip yet!

On cart mount units, place the suction tube (21) in the fluid container.

On wall mount units, screw the bung adapter (34) into the container's bung hole, slide the suction tube through the adapter into the container, and tighten the thumbscrew (33) to secure. Position the tube so its end is about 1/2 in. (13 mm) off the bottom of the container.

On pail mount units, fill the pail (40) with fluid. Set the cover (1) on the pail and secure with the thumbscrews (42).

Open the drain valve (6) to prime the pump. Open the bleed-type master air valve (16). Open the gun air regulator (10a). Hold a metal part of the spray gun firmly to the side of a grounded metal pail and trigger the gun.
