How to use the pressure control.

The pressure control controls the motor operation so the sprayer maintains constant fluid pressure at the pump outlet. Turn the pressure control knob fully counterclockwise to obtain the minimum setting. Turn the knob clockwise to increase pressure. See Fig. 6.

How to use the pressure drain valve.

Use the pressure drain valve to relieve fluid pressure from the pump and to help prime the pump. If the valve senses an over pressure condition, it opens automati- cally to relieve fluid pressure. If this happens, stop spraying immediately, shut off and unplug the sprayer. Determine the cause of the problem and correct it before operating the sprayer again. Refer also to the Troubleshooting , page 13. See Fig. 5.
