Pressure Relief Procedure

WARNING

SKIN INJECTION HAZARD

The system pressure must be manually relieved to prevent the system from starting or dispensing 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/dispensing,

Dcheck or service any of the system equipment,

Dor install or clean the spray tip/nozzle.

1.Lock the gun/valve trigger safety.

2.Close the pump’s bleed-type air valve (required in your system).

3.Shut off the master air bleed valve (required in your system).

4.Unlock the gun/valve trigger safety.

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

6.Lock the gun/valve 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/dispense again.

If you suspect that the spray tip/nozzle 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/nozzle or hose.

Packing Nut/Wet-Cup

Before starting, fill the packing nut (2) 1/3 full with Graco Throat Seal Liquid (TSL) or compatible solvent. See Fig. 3. Adjust the packing nut weekly so it is just snug; do not overtighten.

WARNING

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