For more material volume try a larger nozzle. • When adjusting flow nut, release trigger, then adjust. • If adjusting while triggered, needle will turn but provide no adjustment. • If nut will not turn, check to see if it is either set to maximum adjustment or there is material on threads. Clean threads as needed. • Test spray pattern on cardboard. Hold gun 18 to 24 in. (45.7 to 60.9 cm) from surface. Using a circular motion, overlap each stroke. To Get Less Material Try one or a combination of these methods: Adjusting the System Sufficient fluid output (volume and pressure) and good atomization is a balance of atomizing air, material thickness/material flow and nozzle selection. Achieving the correct balance for your application requires experimentation to achieve desired results. Keep in mind these important points when adjusting gun: • Open air valve • Turn gun flow adjustment nut to decrease flow, counter-clockwise • Use smaller nozzle To Get More Material 1. Select proper nozzle for your application. See Nozzle Selection Chart. Remember, the larger the nozzle, the heavier the pattern. 2. Start with gun air flow valve completely open. If needed, slowly close gun air flow until you get a good spray pattern. Try any one or a combination of these methods: • Close air valve • Turn gun flow adjustment nut to increase flow, clockwise • Use thinner material mixture • Use a larger nozzle For Continuous Spraying Use trigger lock to hold trigger open and reduce fatigue. ti8528a 3. Adjust air flow adjustment nut and air valve to achieve uniform, round spray pattern. It may be necessary to change spray nozzles to achieve the desired spray pattern. Check Material Consistency Periodically Check and thin material as needed to maintain proper consistency. The material may thicken as it sits and slow down production. Agitate periodically. ti8539a 311776B 7 Cleanup Cleanup Once you have finished spraying, follow these steps to clean your gun and hopper. 1. Shut off compressor. 8. Turn on compressor. 9. Open gun air valve, forcing air through tip to clear out any remaining material. 2. Disconnect air line from gun. ti8528a 10. Disconnect compressor. ti8568a 3. Drain remaining material into a bucket until most of the texture material is out of hopper. 4. Fill hopper with clean water. Remove nozzle from gun and allow water to flow through and out of gun. Be sure to keep air passages in needle clean and free of material. To improve working condition for future use, after cleaning, apply a few drops of light oil to: 5. Flush until gun is clean. • Air hose quick disconnect 6. Remove hopper from gun and finish cleaning all components. A soft brush may be used to help loosen any dried on material from surface. • Material hose connections • Flow adjustment on gun 7.
