Anleitung Zusammenfassung
1. Shut off the pump or sprayer. 2. Trigger the gun. 3. Open the gun air valve. 4. Disconnect the power source. Grounding To reduce the risk of electric shock, proper electrical grounding is essential. See your separate pump or sprayer instruction manual, and consult your local electrical codes for detailed grounding instructions. Working Pressure To reduce the risk of component rupture and serious bodily injury, never exceed 100 psi (7 bar) AIR OR FLUID WORKING PRESSURE to this gun. Do not exceed the maximum working pressure of any other component in the system. Fluid and Solvent Compatibility Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in this equipment, which contains aluminum and/or zinc parts. Such use could result in a serious chemical reaction, with the possibility of explosion, which could cause death, serious bodily injury and/or substantial property damage. The standard gun adjustment is to adjust the air needle slightly behind the fluid tip. Fully open air valve (3), while adjusting needle valve (5) for the minimum air flow necessary for a good pattern. Air bleeds from the gun nozzle whenever the gun air valve (3) is open. Close the valve to stop the air, if desired. Otherwise, it can stay open except during priming. To prevent material surge at the beginning of a spray pattern, open valve (17) slowly while moving gun quickly. Adjusting the spray pattern requires testing to balance the pump pressure and the air to the gun, and using the right tip size. Spray Techniques 1. Test the spray pattern on cardboard. Hold the gun 18 – 30 in. (457 – 762 mm) from the surface. Use this spraying distance for most applications. 2. Adjust fluid pressure until material flow is adequate. 3. Adjust the gun air flow valve (5) to achieve a uniform, round spray pattern. 4. Consider the size of aggregate in the material and the coarseness of the spray pattern. Remember, the larger the tip, the heavier the pattern. 5. Overlap each stroke 50%. 6. A circular, overlapping pattern may give the best results, and is obtainable by grasping the flexhead (2) and swinging the head around as the hose flexes. 7. Use appropriate procedure for your sprayer: a. TexSpray EXT HP, Compact HP and Twin Tank EXT: Make sure air bleeds from the aluminum tube when there is material pressure. b. RTX 1500:Turn air supply off when sprayer is not in use. NOTE: Adjust fluid pressure to lowest pressure needed to maximize efficiency of gun adjustments. GRACO INC. P.O. BOX 1441 MINNEAPOLIS, MN 55440–1441 COPYRIGHT 1996, GRACO INC. Graco Inc. is registered to I.S. EN ISO 9001 When spraying small, confined areas, use the valve and knob to make fine adjustments without adjusting the pump. Material flow adjustments (Fig. 1) For a lighter spray pattern, adjust the air needle (18) closer to the fluid tip and/or reduce the fluid pressure. For a heavier spray pattern, adjust the air needle (18) farther back from the fluid tip and/or increase the fluid pressure. NOTE: Withdrawing needle valve (18) too far can force air back into fluid hose, stopping material flow. Air flow valve adjustment To decrease air flow turn the valve (5) clockwise. To increase air flow, turn the valve (5) counter clockwise. Check and thin the material as needed to maintain the proper consistency. The material may thicken as it sits and slow down production or affect the spray pattern. Flush and dry gun thoroughly at end of each work day.
