grees to spray.
Adjust the handspray pressure with the “Return”
valve. Turn the “Return” valve clockwise to increase
the handspray pressure. Do not close the “Return” valve

closed position and pressure in the wand is insufficient,
turn the “Return” valve counter clockwise and increase
the asphalt pump flow rate.
