Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying acci- dentally. To reduce the risk of an injury from acci- dental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Proce- dure whenever you:

Dare instructed to relieve the pressure, D stop spraying,

D check or service any of the system equipment, D or install or clean the spray tip.

1.Lock the spray gun safety latch.

2.Shut off the air supply to the pump.

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

4.Unlock the gun safety latch.

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 gun safety latch.

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 ring 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. 3. Therefore, never oper- ate the pump with the air motor plates removed.

Flush the Pump Before First Use

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

For your safety, read the warning section, Fire or Explosion Hazard, on page 4 before flushing, and follow all the recommendations given there.
