Operation

Pressure Relief Procedure

WARNING

SKIN INJECTION HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid

under high pressure can be injected 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 tip.

1.Lock the gun trigger safety.

2.Close the bleed-type master air valve (D, required in your system). See Fig. 2.

3.Unlock the gun trigger safety.

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

5.Lock the gun trigger safety.

6.Open the drain valve (J, required in your system), having a container ready to catch the drainage.

7.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 HAZARD

Do not operate without the air motor plates (P, Fig. 3) in place. Pinching or amputation of fingers or hands may occur. See MOVING PARTS HAZARD on page 3.

Packing Nut

Keep the packing nut/wet-cup (36) filled with Graco Throat Seal Liquid (TSL) or compatible solvent, to help prolong the packing life. See Fig. 3.

WARNING

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

The packing nut is torqued at the factory and is ready for operation. If it becomes loose and there is leaking from the throat packings, relieve pressure, then torque the nut to 18–20 ft–lb (24–27 N.m). Do this whenever necessary. Do not overtighten the packing nut.

Flush the Pump Before First Use

The pump is tested with lightweight 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. See Flushing on page 11.
