When spraying small, confined areas, use the valve and knob to make fine adjustments without adjusting the pump.
Air flow valve adjustment
To decrease air flow turn the valve (5) clockwise.
Material flow adjustments (Fig. 1)
For a lighter spray pattern, adjust the air needle (18) closer to the fluid tip and/or reduce the fluid pressure.
To increase air flow, turn the valve (5) counter clock- wise.
For a heavier spray pattern, adjust the air needle (18) farther back from the fluid tip and/or increase the fluid pressure.
NOTE: Withdrawing needle valve (18) too far can force air back into fluid hose, stopping material flow.
Check and thin the material as needed to maintain the proper consistency. The material may thicken as it sits and slow down production or affect the spray pattern.
Flush and dry gun thoroughly at end of each work day.
