Warnings Warnings The following are general warnings related to the setup, use, grounding, maintenance and repair of this equipment. Additional, more specific warnings may be found throughout the body of this manual where applicable. Symbols appearing in the body of the manual refer to these general warnings. When these symbols appear through the manual, refer back to these pages for a description of the specific hazard.
Warnings Warnings Electric Shock Hazard To reduce the risk of electric shock: • Be sure sprayer is adequately grounded through electrical outlet. • Use only 3-wire, extension cords. • Make sure ground prongs are intact on sprayer and extension cords. Improper installation of grounding plug will result in a risk of electrical shock, fire or explosion that could cause serious injury or death. • Do not operate with cover removed. • Turn off sprayer.
Warnings CAUTION Water or material remaining in unit when temperatures are below freezing can damage motor and/or delay pump startup. To insure water and material are completely drained out of unit: 1. Remove material line from sprayer. 2. Tip sprayer up as shown. ti9075a J ti8376a 4 Before adding material or starting unit in cold weather, run warm water through pump. Before adding material to hopper, install burp guard (J).

Preparation Preparation Pressure Relief Procedure To reduce risk of injury, follow this procedure whenever you see this symbol throughout this manual, Also, perform this procedure whenever you: • Stop spraying • Check or repair any part of this system • Install or clean spray nozzle Check with a qualified electrician or serviceman if grounding instructions are not completely understood, or if in doubt as to whether the product is properly grounded.
Setup Setup Important • To increase pump life, turn power off when not spraying. • Do not allow material to dry inside pump, hoses, gun or spray system. • To break in new pump run dry for no more than 2 minutes. 4. Connect material hose to gun. Texture Spraying 1. Connect air hose to user-supplied air compressor & material hose (G) to material hose outlets. ti8705a 5. Install spray nozzle. See Recommended Nozzle Selection Chart, page 10. ti8375a 2. Connect user supplied air hose to gun.
Setup 11. Continue to trigger gun and spray into waste bucket until a steady stream of material sprays out of gun. 12. Turn on Air compressor and open gun valve to desired setting. ti9202a 8. Point gun into waste bucket and pull trigger to pump water through the system. Continue to trigger gun until material hopper is empty. 9. Install burp guard (J). Caution, page 3. ti9775a 13. To achieve uniform spray pattern, adjust air valve and flow adjustment nut on gun.
Mixing Material Mixing Material Correct material mixture is essential. The pump will not operate if the mixture is too thick. Mix the material in a separate container before pouring it into hopper. 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. 4.
Spray Techniques Spray Techniques Recommended Nozzle Selection Chart Application Nozzle Size2 Air Volume1 Simulated Acoustic 6 mm, white (fine to medium) 8 mm, gray (coarse) Orange peel 6 mm, white Splatter coat Knockdown 6 mm, white 8 mm, gray 8 mm, gray medium to high medium to high low to medium low 1Control air volume with gun air valve. 2 For more material volume try a larger nozzle. To Get Less Material Try one or a combination of these methods: • Open air valve.
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. 5.
Troubleshooting Troubleshooting Problem Sprayer won’t run Pump won’t pump material Cause Power switch not on Turn switch on. No power at wall outlet Check outlet by plugging in another appliance. If appliance does not work, try another outlet. Wrong size generator Use a 3500 watt or larger generator. Refer to Generator Requirements, page 6. Breaker tripped Reset breaker. Air lock Open air valve on gun. Mix too thick Add water to thin material. Use Material Thickness Gauge.
Troubleshooting Problem Speed of application slow or slower Cause New pump hose not broken in properly Solution Run pump dry for no more than 2 minutes. Material too thick Thin material. Nozzle too small Change nozzles to a larger size. See Recommended Nozzle Selection Chart, page 10. Too much air being used Partially close gun air valve to reduce air flow. Pump hose worn Replace hose. Plugged or dirty gun Relieve Pressure, page 6. Clean gun. Kinked hose Unkink hose.
