10. Adjust spray pattern.
a. Increase pressure just until spray from gun is
completely atomized. Use lowest pressure
necessary to get desired results. This reduces
overspray and fogging, decreases tip wear and
extends the life of the sprayer.
b. For more coverage, use larger tip rather than
increasing pressure.
c. Test spray pattern. To adjust pattern, engage
gun safety latch, loosen retaining nut. Position
tip guard horizontally for horizontal pattern or
vertically for vertical pattern. Then tighten
retaining nut. Fig. 5.
