STARTUP

1.Place the suction tube 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 tube (if the tube 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 off. Heavy viscosity paint may need to be thinned. Be sure to follow the paint manufacturer's recommendations on thinning.

6.When the outlet hose and extension tube are fully primed, the motor will run when there is paint de- mand, but appears to shut itself off 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.

CAUTION

Always allow cold equipment to warm to room tem- perature before using to prevent damaging the sys- tem. Always store the system indoors.

CAUTION

Do not use lacquer or lacquer thinner in the suction and outlet hoses supplied with this system. These fluids quickly destroy the hose material. Use the op- tional chemical±resistant hoses.

See ACCESSORIES, page 17, for ordering optional hoses.

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.To adjust the extension tube length, loosen the lock- nut and extend or retract the tube. If retracting, some paint in the tube will be pushed out to the roller. Roll this excess paint onto the wall, or completely retract the tube, drain the excess paint into a pail, and then adjust the tube length. Tighten the locknut securely.

4.Whenever you stop painting, turn the ON/OFF switch to OFF and trigger the roller valve. Elevate the roller end of the tube to prevent paint from draining out the roller end.

5.Flush the system thoroughly and immediately after each use to keep it in good working order. See page 6.
