Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Warnings FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion: • Do not spray or clean with flammable materials. Use water-based materials only. • Use equipment only in well ventilated area. • Sprayer generates sparks. When flammable liquids are used near the sprayer, keep sprayer at least 20 feet (6.1 meters) away from explosive vapors. • Keep work area free of debris, including solvent, rags and gasoline.
Warnings PRESSURIZED EQUIPMENT HAZARD Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury. • Follow the Pressure Relief Procedure when you stop spraying/dispensing and before cleaning, checking, or servicing equipment. • Tighten all fluid connections before operating the equipment. • Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

Preparation Preparation Grounding Pressure Relief Procedure Follow the Pressure Relief Procedure whenever you see this symbol. This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid or splashed fluid follow the Pressure Relief Procedure whenever sprayer is stopped and before sprayer is cleaned or checked, and before equipment is serviced. 1. Turn ON/OFF switch to the OFF position. Wait 7 seconds for power to dissipate.
Preparation Hose Size and Length Soft Start The system comes with a 25 ft (7.6m) long hose set consisting of a material hose 1 in. or 1.25 in. I.D. and a 3/8 in. I.D. air hose. The Soft Start System is controlled by motor power and an air cylinder. When pressurized, the air cylinder pushes the rollers into the peristaltic pump pushing material through the pump. When the motor shuts off, a solenoid valve relieves the pressure in the air cylinder causing the rollers to disengage from the peristaltic pump.
Setup Setup 3. Install spray nozzle. See Recommended Nozzle & Disc Selection Charts, page 15. Pulling trigger when installing nozzle makes assembly easier. NOTICE • • Do not store sprayer under pressure. Do not allow material to dry inside pump, hoses, gun or spray system. This may cause pump to fail. When unpacking sprayer for the first time or after long term storage perform setup procedure. 1. Connect one end of air hose to sprayer air outlet quick connect and to gun air inlet quick connect.
Setup Material Hopper Mixing Material Install Hopper 1. Position hopper outlet over fitting as far as it will go. NOTE: Correct material mixture is essential. The pump will not operate if the mixture is too thick. Use water-based materials only. ti27957a 2. • Mix the material in a separate container before pouring it into hopper. • Use Material Thickness Gauge to determine if mixture is thin enough to spray.
Setup Premix 3. Slowly add approximately 2 to 4 quarts (1.9 to 3.8 liters) of water to a 5 gallon (18.9 liter) bucket of premix. Allow ceiling texture to set for at least 15 minutes. Then remix prior to use. 4. After texture material is thoroughly mixed, gently set ball end of Material Thickness Gauge on surface of mixture. NOTE: For an accurate test, be sure gauge is completely dry and clean every time it is used. 5. PREMIX 5 GAL Observe the ball on the material.
Operation Operation For the best spraying experience always follow the Setup and Operation process. This ensures that the material and sprayer are ready to spray resulting in a successful project. 4. Trigger gun into waste pail until hopper no longer contains water and all water is removed from hose and pump system. NOTICE To prevent pump damage, before adding material or starting unit in cold weather, run warm water through the pump.
Operation Alternate Method (Using Prime Valve) Use this method when air flow with material through gun is not desired 1. Turn ON/OFF switch to ON position. 2. Turn fluid flow regulator up as necessary. Air hose fittings can get hot. Allow sprayer to cool down 15 minutes before removing air hose. Texture Spraying 1. Fill hopper with prepared texture material. 2. Install nozzle or nozzle and disc. See Recommended Nozzle & Disc Selection Charts, page 15. ti27952a 3. Close gun air control valve.
Operation 5. Follow Mixing Material, page 11. 6. Trigger gun into a pail. When texture material appears at nozzle, move gun to hopper and circulate until there is a solid stream of texture material. 8. To achieve uniform spray pattern, adjust air control valve and flow adjustment nut on gun. If you do not achieve the desired pattern, change nozzles, see Recommended Nozzle & Disc Selection Charts, page 15. ti27962a 7.
Operation 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: • • To select correct nozzle for your applications, consider size of aggregate in material and coarseness of spray pattern.
Operation Smart Start/Soft Start Operation Smart Start Sprayer will start under the following conditions: • A new sprayer is plugged in and ON/OFF switch is turned ON. • Gun is triggered and air control valve is open far enough. • There is a small leak in the system and the pressure drops below the pressure switch setting. This may appear to be random operation. • • When a bleeder gun is used. • • Prime valve is opened.
Shutdown and Cleanup Shutdown and Cleanup NOTE: Keep pump and hose clean when switching between materials. A dirty pump can release particles of texture into the finish. • To increase pump life, life turn ON/OFF switch OFF when not spraying. • Before removing material hose, perform Pressure Relief Procedure, page 8. Make certain there is no material in the hose. • To keep sprayer in good operating condition, always clean it throughly and prepare it properly for storage.
Shutdown and Cleanup 16. Open gun air control valve. Perform Pressure Relief Procedure, page 8. 2. Lift material hopper straight up, off the unit. 17. Finish cleaning all components. Be sure to keep air passages in needle clean and free of material. Clean inside of gun. 3. Plug opening on bottom of material hopper with your hand. NOTE: A soft brush can be used to loosen dried on material.
Maintenance Maintenance Routine maintenance is important to ensure proper operation of your sprayer. Maintenance includes performing routine actions which keep your sprayer in operation and prevent trouble in the future. Component Task Interval Sprayer Inspect motor shield vents for Daily or each time you spray blockage. Hoses Check for wear and/or damage. Drain system of all water. Add a few drops of light oil. Daily Flush Check thread connections for wear.
Troubleshooting Troubleshooting Problem Sprayer won’t run 1. Follow Pressure Relief Procedure, page 8, before checking or repairing. 2. Check all possible problems and causes before disassembling the unit.
Troubleshooting Problem Speed of application slow or slower Cause Material too thick Nozzle too small Thin material. Change nozzles to a larger size. See Recommended Nozzle Selection Chart, page 15. Too much air being used. Partially close gun air control valve to reduce air flow. Replace hose. Perform Pressure Relief Procedure, page 8. Clean gun. Unkink hose. Increase flow adjustment with flow adjustment nut. Unplug other items from circuit.
Troubleshooting Problem Cause Power switch is on and sprayer Material and/or water is frozen is plugged in, but motor does or hardened in pump. not run, and pump does not cycle. (cont’d) Solution Unplug sprayer from outlet. If frozen do NOT try to start sprayer until it is completely thawed or you may damage the motor, control board and/or drivetrain. Make sure power switch is OFF. Place sprayer in a warm area for several hours. Then plug in powercord and turn sprayer ON.
