Operation

Pressure Relief Procedure

WARNING

SKIN 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.Shut off the air to the pump.

3.Close the bleed-type master air valve (required in your system).

4.Unlock the gun trigger safety.

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

6.Lock the spray gun trigger safety.

7.Open the drain valve (required 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

Moving parts can pinch or amputate your fingers or other body parts. When air is supplied to the motor, the air motor piston (located behind the air motor plates) moves. See Fig. 2. Therefore, never oper- ate the pump with the air motor plates removed.

Flush the Pump Before Using

The pump is tested with lightweight motor oil, which is left in to protect the pump parts. If the fluid you are using may be contaminated by the oil, flush it out with a compatible solvent before using the pump. If the pump is being used to supply a circulating system, allow the solvent to circulate until the pump is thor- oughly flushed.

WARNING

FIRE AND EXPLOSION HAZARD For your safety, read the section FIRE AND EXPLOSION HAZARD on page 4 before flushing and follow all the recom- mendations given there.
