PRESSURE SPRAYING
After selecting correct size fluid, set fluid pressure for the desired flow. Open atomization air and test
spray. If spray is too fine, then reduce air pressure. If spray is too coarse, then raise air pressure. Adjust
pattern width and repeat adjustment of spray.
Keeping fluid control screw in open position will reduce fluid needle wear.
NOTE: To reduce overspray and obtain maximum efficiency, always spray with the lowest possible
atomization air pressure.
Proper handling of the gun is essential for obtaining a good finish. The gun should be held at right
angle to the surface being covered, moving parallel with the surface. For precise control of the gun
and material, the trigger should be released before the end of the stroke.
Hold the gun from 6 to 12 inches (15,24cm to 30,48cm) away from the surface depending on material
and atomizing pressure. For a uniform finish, lap each stroke over the preceding stroke, making sure
the spray is smooth and wet.
Using the lowest possible atomizing air pressure will reduce over-spray and provide maximum efficiency.
