Be sure they are in good condition and have undamaged three-pin plugs. Replace immediately if either cord shows signs of wear or damage. 3. Plug the power supply cord into a properly grounded, 120 V electrical outlet. See Fig 2. Do not use an adapter. All extension cords must have three wires. Use the chart below for selecting the appropriate wire gauge for the extension cord. . . PRIMING VALVE PAINT FILTER USE TWO WRENCHES TO TIGHTEN 25 FT.

STARTUP WARNING Pressure Relief Procedure To reduce the risk of serious bodily injury, including injury from moving parts, or electric shock, always follow this procedure whenever you shut off the system, when checking or servicing any part of the system and whenever you stop painting. 1. Turn the ON/OFF switch to OFF. 2. Unplug the power supply cord. 3. Trigger the roller valve to relieve pressure. Ifyou suspect that pressure is not fully relieved after followingthe steps above,open the priming valve 2 turns counterclockwise. 1. Place the suction hose in the pail of paint. 2. Plug in the sprayer. 3. Open the priming valve 2 turns counterclockwise. 4. Turn the ON/OFF switch ON. 5. You can see the paint being drawn into the suction hose (if the hose is clean). As soon as you see paint flow through the priming tube, close the priming valve. This usually takes less than 30 seconds. CAUTION Failure to completely close the priming valve after the system is primed will cause the valve to erode, greatly shortening the valve life. NOTE: If your system is hard to prime, first try to force feed the suction tube. Hold the suction tube in a vertical position and pour paint into it. Turn on the system. If the system does not prime within one minute, shut it of f. Heavy viscosity paint may need to be thinned. Be sure to follow the paint manufacturer’s recommendations on thinning. 6. Trigger the roller valve to prime the outlet hose and extension. Once primed, the motor will run when there is paint demand, but appears to shut itself of f when there is no paint demand. NOTE: An occasional start and stop of the motor when the roller valve is not triggered is normal. OPERATION WARNING To reduce the risk of electric shock, do not expose the system to rain. Always store the system indoors. Do not operate the pump with the base cover removed. CAUTION Always allow cold equipment to warm to room temperature before using it to prevent damaging the system. 1. With the system fully primed, trigger the roller valve briefly until paint comes to the roller. 2. Experiment with triggering and rolling the paint until you determine just how often you need to trigger the roller valve to keep an even flow of paint to the roller. 3. Whenever you stop painting, turn the ON/OFF switch to OFF, and trigger the roller valve. Then elevate the roller end of the extension to prevent paint from draining out the roller end. 4. Thoroughly flush the system immediately after each use to keep it in good working order. See page 8. . . MAINTENANCE CAUTION Thorough flushing and proper maintenance areessential to keep your system working properly. Improper flushing or maintenance may prevent the system from working the next time you need it, and may result in costly damage to the system. Alwaysflush your system thoroughly and immediately after each use. Alwaysdrain all water out of the roller valve and extension and leave the system filled with mineral spirits to prevent corrosion. NOTE: A Garden Hose Flush Adapter, P/N 220–231, is included. This adapter is placed at the pump inlet and uses a standard city water supply to aid in flushing. Instructions on how to use it are included with the adapter. Flushing Procedure (Latex Paint Only) 1. Turn the ON/OFF switch to OFF. 2. Trigger the roller valve and roll out the excess paint from the roller onto a wall or newspaper. Remove the roller cover and dif fuser, and soak these parts in a pail of warm, soapy water. 3. Put the suction tube in a pail of warm, soapy water. Hold the roller frame over the paint pail, turn on the system, and trigger the roller valve to drain and save the paint in the hoses. See Fig 3. Release the trigger and shut of f the pump as soon as all the paint is drained. This avoids contaminating the paint with the flushing water. 4. Now hold the roller frame over the flushing pail. Turn on the pump and trigger the roller valve. Circulate the solution for three to five minutes (five to ten minutes if using a cold solution). Open the priming valve for a few seconds to clean the priming tube. Close the priming valve. 5. Raise the suction hose above the water and run the pump for a few seconds to drain the flushing solution. Shut off the pump. 6. Wash off al...
