WARNING INJECTION HAZARD Spray from the gun, leaks or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can also cause serious injury. D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medical attention. D Do not point the gun at anyone or at any part of the body. D Do not put your hand or fingers over the spray tip.
WARNING FIRE AND EXPLOSION HAZARD Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury. D If there is any static sparking or you feel an electric shock while using this equipment, stop spraying immediately. Do not use the equipment until you identify and correct the problem. D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid being sprayed.
Installation/Operation System Requirements WARNING Keep the wallet-sized warning card provided with this gun with the operator at all times. The card contains important treatment information should an injection injury occur. Additional cards are available at no charge from Graco Inc. WARNING Be sure your system has a bleed-type master air valve (pneumatic pumps only) and a pressure drain valve.
Installation/Operation How to Use the Gun 1. Connect a grounded fluid hose to the gun inlet. See Fig. 2 2. With no tip installed, start the pump. Flush the pump according to the instructions supplied with it. Prime the system with the fluid. 3. Follow the Pressure Relief Procedure on page 5. Be sure the gun trigger safety is engaged. See Fig. 1. 7. If adjusting the pressure does not give a good spray pattern, follow the Pressure Relief Procedure on page 5 and then try another tip size. 8.
Installation/Operation How to Clean the Spray Tip and Clear a Spray Tip Obstruction WARNING To reduce the risk of fluid injection or splashing in the eyes or on the skin, do not hold a hand, body or rag in front of the spray tip when cleaning or checking a clogged tip. Point the gun toward the ground or into a waste container when checking to see if the spray tip is cleared. DO NOT try to “blow back” paint; this is NOT an air spray gun.
Installation/Operation How to Check the Gun Diffuser Operation 4. Apply lithium-base grease to the threads of the gun handle (14) and reassemble the gun. Check the diffuser operation weekly. The gun diffuser/ seat (A) breaks up spray and reduces the risk of fluid injection when the tip is not installed. Perform the test below. If it fails, replace the entire Needle Kit, Part No. 218070, as instructed on page 7.
Installation/Operation How to Flush the Gun WARNING ÄÄ To reduce the risk of serious bodily injury, including splashing fluid in the eyes or on the skin, or static electric discharge when flushing: D Be sure the entire system, including flushing pails, are properly grounded. D Remove the tip guard and spray tip. D Maintain metal to metal contact between the gun and the flushing pail. D Use the lowest possible pressure. Always flush the pump and the gun before the fluid being sprayed can dry in it.
