Adjusting the Spray Pattern
a. Increase the pressure adjusting knob setting
just until spray from the gun is completely
atomized. To avoid excessive overspray and
fogging, and to decrease tip wear and extend
the life of the sprayer, always use the lowest
possible pressure needed to get the desired
results.
b. If more coverage is needed, use
rather than increasing the pressure.
c. Test the spray pattern. To adjust the direction
of the spray pattern, engage the gun safety and
loosen the retaining nut. Position the tip guard
horizontally for a horizontal pattern or vertically
for a vertical pattern. Then tighten the retaining
nut.
