10. Adjust the spray pattern.
a. Increase the pressure just until spray from the
gun is completely atomized. To avoid exces-
sive overspray and fogging, and to extend tip
and sprayer life, always use the lowest pres-
sure needed to get the desired results.
b. If more coverage is needed, use a larger tip
rather than increasing the pressure.
c. Test the spray pattern. To adjust the direction
of the spray pattern, engage the gun safety
latch and loosen the retaining nut. Position the
tip guard horizontally for a horizontal pattern or
vertically for a vertical pattern. Hold the tip
guard in place while tightening the retaining
nut. See Fig. 9.
NOTE: Spray patterns will change as tips wear.
Change the spray tip if adjusting the pressure will not
improve the spray pattern.
