Operation
Be sure to read and follow the Warnings on pages 4 and 5 and throughout the text of this instruction manual.
Keep the wallet sized warning card (222385), provided with the gun, with the operator of this equipment at all times. The card contains important treatment informa- tion should a skin injection injury occur. Additional cards are available at no charge from Graco.
Pressure Relief Procedure
Trapped air can cause the pump to cycle unexpect- edly, which could result in serious injury from splash- ing or moving parts.
To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Proce- dure whenever you:
•are instructed to relieve the pressure,
•stop spraying,
•check or service any of the system equipment, or install or clean the spray tip.
1.Engage the trigger lock. See FIG. 12.
2.Shut off the pump. See your pump manual.
3.Shut off the gun air supply.
4.Disengage the trigger lock. See FIG. 12.
5.Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun to relieve pressure. See FIG. 11.

6.Open all fluid drain valves in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to spray again.
7.Engage the trigger lock. See FIG. 12.
8.If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved after follow- ing the steps above, VERY SLOWLY loosen the tip guard retaining ring or hose end coupling to relieve pressure gradually, then loosen completely. Clear hose or tip obstruction.
Trigger Lock
Always engage the trigger lock when you stop spraying to prevent the gun from being triggered accidentally by hand or if dropped or bumped.
