Follow these steps:

1. Plug the sprayer into a grounded electric receptacle. If using an extension cord, refer to the extension cord gauge chart for proper use.

2. The knob nearest the front of the sprayer is the prime/spray knob. Make sure this knob is in the “Prime” position.

3. The knob nearest the rear of the sprayer is the pressure knob. When you first turn the power on, this knob should be in the “Low-Pressure” position.

4. Place both the suction and bypass tubes into a container of fluid.

5. Turn the pressure knob to “High.”

6. When fluid begins to come out of the bypass tube, and there are no air bubbles visible in the tube, turn the prime/spray knob to “Spray.”
