WARNING
INJECTION HAZARD
Remember, this is not an air spray gun. For your safety be sure to read and follow the Warnings on pages 2 and 3
and throughout the text of this instruction manual.
Keep the wallet sized warning card 179±960, provided with the gun, with the operator of this equipment at all times. The card contains important treatment information should an injection injury occur. Additional cards are available at no charge from Graco.
Pressure Relief Procedure
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 spray gun trigger safety to avoid acciden- tally triggering the gun. See Fig. 2.
2.Shut off the power to the pump.
3.Close the
4.Unlock the gun trigger safety.
5.Hold a metal part of the gun firmly to the side of a grounded metal waste container and trigger the gun to relieve the fluid pressure.
6.Lock the gun trigger safety again.
7.Open the pump drain valve (required in the sys- tem) to help relieve fluid pressure in the displace- ment pump. In addition, open the drain valve connected to the fluid pressure gauge (in a system with fluid regulation) to help relieve fluid pressure in the hose and gun. Triggering the gun to relieve pressure may not be sufficient. Have a container ready to catch the drainage.
8.Leave the drain valve(s) open until you are ready to spray again.
9.If you suspect that the spray tip or hose is com- pletely clogged or that pressure has not been fully relieved after following the steps above, very slowly loosen the hose end coupling and relieve pressure gradually, then loosen the coupling completely. Now clear the tip or hose obstruction.
