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 14. See Fig. 6.

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. 7.
