6. Without the tip installed, start the pump or sprayer and flush it according to the pump or sprayer instructions. Prime the pump or sprayer with the fluid you are going to spray. Continued on the next page. ....... . Installation 7. Follow the Pressure Relief Procedure on page 6. 8. Engage the gun safety ring (20), see Fig. 2, page 6. 9. Unscrew the tip guard (17) and install the spray tip (A) and gasket (16) in the tip guard nut. See Fig. 1, page 4. NOTE: The gun will leak if the tip gasket (16) is not installed. 10. Disconnect the harness (7) clip from the gun ring (5). 11. Place the harness (7) over one shoulder and across the chest. Fasten the belt around the waist. Adjust the length of the shoulder strap as needed. 12. Check that the handle grip (9) is in a comfortable position. To adjust it, loosen the screw (3) and nut (1), rotate the grip to a good position, and firmly tighten the screw and nut. Ground the System WARNING FIRE AND EXPLOSION HAZARD Improper grounding could cause static sparking, which could cause a fire or explosion. To reduce the risk of property damage or serious injury, follow the grounding instructions below. The following grounding instructions are minimum requirements for a system. Your system may include other equipment or objects which must be grounded. Check your local electrical code for detailed grounding instructions for your area and type of equipment. Your system must be connected to a true earth ground. 1. Pump/Sprayer: Ground the pump/sprayer by connecting a ground wire and clamp between the pump/sprayer and a true earth ground as instructed in the equipment’s instruction manual. 2. Air compressor: Ground according to the manufacturer recommendations. 3. Air and fluid hoses: Use only grounded hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity. Check the electrical resistance of your air and fluid hoses at least once a week. If the resistance exceeds the recommended limits, replace the hose immediately. 4. Pole gun: Ground the gun by connecting it to a properly grounded fluid hose and pump. 5. Fluid supply container: Ground it according to local code. 6. Object being sprayed: Ground it according to local code. 7. All solvent pails used when flushing: Ground them according to local code. Use only metal pails, which are conductive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts the grounding continuity. 8. To maintain grounding continuity when flushing or relieving pressure: Always hold a metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun. ......... Operation Safety Pressure Relief Procedure 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. WARNING 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: . are instructed to relieve the pressure, . stop spraying, . check or service any of the system equipment, . or install or clean the spray tip. Opening and Closing the ON/OFF Lever Always fully open or fully close the ON/OFF lever (B). Any other position will quickly damage the valve seat, and the ON/OFF ball valve (8) may not completely stop the flow of fluid when closed. To open the ON/OFF lever (B),slide the safety ring (20) off the lever and pull the lever completely back, toward yourself. See Fig. 2. To close the ON/OFF lever (B),push the lever completely forward, toward the spray tip, and slide the safety ring (20) over the lever. See Fig. 2. B 1 ON/OFF lever in open position. ON/OFF lever in closed position. Fig. 2 06302 20 8 B2 1 2 1. Fully close the gun ON/OFF lever (B). See Fig. 2. 2. Slide the safety ring (20) over the gun ON/OFF lever. 3. Close the pump air regulator. 4. Close the bleed-type master air valve (required in the system). 5. Slide the safety ring off the gun ON/OFF lever. 6. Hold a metal part of the gun firmly to the side of a grounded metal waste container and open the gun ON/OFF lever to relieve the fluid pressure. 7. Fully close the gun ON/OFF lever, and slide the safety ring over the lever. 8. Open the pump drain valve (required in the system) to help relieve fluid pressure in the displacement pump. Triggering the gun to relieve pressure may not be sufficient. Have a container ready to catch the drainage. 9. Leave the drain valve open until you ar...
