3.Test the spray pattern atomization while keeping the gun a consistent distance, about 6 to 8 inches (150 to 200 mm), from the test piece.

Check the atomization quality. Increase the gun atomizing air supply pressure with the air pressure regulator in 5 psi (34 kPa, 0.3 bar) increments until you obtain the desired atomization.

For the best transfer efficiency, use the lowest set- ting needed to achieve desired finish quality.

4.If the spray pattern is too wide or split, reduce the fan air pressure (or slightly close the fan adjustment valve on manifold 288223).

To further control the spray pattern of airspray guns only, use an alternate air cap. For a list of available air caps, refer to Accessories, page 33.

Reducing the fan air pressure to 0 psi (or fully clos- ing the fan adjustment valve) will produce a round pattern.
