The pump will not operate if the mixture is too thick. Mix the material in a separate container before pouring it into hopper. 5. Observe the ball on the material. When the material is thin enough to spray the ball will sink completely into the mixture. READY ADD WATER Use Material Thickness Gauge to determine mixture is thin enough to spray. *The Material Thickness Gauge will only determine if the material is thin enough to pass through the pump. For some applications or for higher speed spraying, your mixture may need to be thinner. Dry Mix - 40 lb (18 kg) bag For best results, do not use partial bags of material. ti2498a 6. If the ball does not sink completely into the mixture within 10 seconds, add more water, agitate and try test again. Premix 1.

Spray Techniques Spray Techniques Recommended Nozzle Selection Chart To Get Less Material Application Nozzle Size2 Air Volume1 Try one or a combination of these methods: Simulated Acoustic 6 mm, white medium to high • Open air valve. • Turn gun flow adjustment nut to decrease flow, counter-clockwise. medium to high low to medium low • Use smaller nozzle. (fine to medium) 8 mm, gray (coarse) Orange peel Splatter coat Knockdown 4 mm, beige, 6 mm, white 6 mm, white 8 mm, gray 8 mm, gray 12 mm, black To Get More Material 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. Adjusting the System • Use a larger nozzle. Sufficient fluid output (volume and pressure) and good atomization is a balance of atomozing 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: Preventing Material Surge at Gun Trigger 1Control air volume with gun air valve. 2 For more material volume try a larger nozzle. • • Select proper nozzle for your application. See Nozzle Selection Chart. Remember, the larger the nozzle, the heavier the pattern. Start sprayer with gun air flow valve completely open. If needed, slowly close gun air flow until you get a good spray pattern. Use minimum amount of air at spray gun to achieve proper spray pattern and to minimize bounce back. + Test spray pattern on cardboard. Hold gun 18 to 24 in. (45.7 to 60.9 cm) from surface. Use this spraying distance for most applications. • Air and material flow adjustments are made at the gun on all units. RTX 1250 units have a material flow control selector knob (L). + Opening air valve increases air flow through gun, which decreases texture material flow through pump. Pressure will build up in the system when you stop triggering the gun. To prevent material surge at initial gun triggering: • Point gun away from surface you are spraying when you first pull trigger. • When you first start to spray, hold the gun away from the surface and gradually work your way closer to it. • Keep gun moving. • After you begin spraying, trigger the gun as little as possible. For Continuous Spraying Use trigger lock to hold trigger open and reduce fatigue. 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. + Closing air valve decreases air flow through gun, which increases texture material flow through pump. 11 Shutdown and Cleanup Shutdown and Cleanup Keep pump and hose clean when switching between simulated acoustic, knockdown and orange peel applications. A dirty pump can release particles of texture into the finish. CAUTION • To increase pump life, turn power off when not spraying. • Before removing material hose be sure pressure is relieved and material is not in hose. • To keep unit in good operating condition, always clean it thoroughly and prepare it properly for storage. 7. Spray inside material hopper to circulate water through gun and hose. While circulating water, use gun to clean material hopper. Texture Spraying (8-10 gallon Material Hopper) When you have finished spraying: 1. Open gun air valve. ti9084a 8. Partially open gun air valve to use air to achieve better cleaning results. 9. Spray water into a waste bucket to empty material hopper. ti8528a 2. Make sure hopper gun/spray gun selection switch is turned to SPRAY GUN. A soft brush can be used to loosen dried on material. 10. Turn power switch OFF. 11. Open gun air valve. Relieve Pressure, page 6. ti9219a 3. Turn power switch ON. ti9222a 4. Close gun air valve. 5.
