Spraying Techniques

Sprayer is set up for most airless spraying applications. For details on tipselection, tip wear, coat thickness, and so on, see Spraying Techniquesin enclosed Operating Instructions.

Motor runs ONLY when gun is triggered.

Sprayer is designed to stop pumping when gun trigger is released.

Adjusting Pressure to Optimum Setting

Adjust the PressureTurn Pressure Control knob to the right (clockwise)to increase pressure at gun. Turn it to the left(counterclockwise) to decrease pressure.

Prevent Excessive Tip WearSpray should be atomized (evenly distributed,no gaps at edges). Start at low pressuresetting, and increase pressure a littleat a time until paint is atomized.To prevent excessive tip wear,spray at lowest pressurethat atomizes paint.

If maximum pressure ofsprayer is not enough forgood spray pattern, tip is toolarge or too worn. SeeReversible Tip SelectionChart in enclosed OperatingInstructions.
