SPRAYING
Figure 24 - Paint Tailing Pattern
GOOD SPRAY PATTERN
PRACTICE FIRST
1. Be sure paint hose is free of kinks and clear of traffic
or objects with sharp cutting edges.
2. Return
PRESSURE CONTROL KNOB
to its lowest
setting (
counter
clockwise). Figure 21.
3. Turn
PRIMING KNOB
to SPRAY
B
position. Figure
22.
4. Turn
PRESSURE CONTROL KNOB
completely
clock
wise to maximum pressure, Figure 21. Paint
should then begin to flow into the paint hose, causing
it to stiffen.

5. Unlock SPRAY GUN TRIGGER LOCK by turning lock
down toward the bottom of the handle. Figure 4
6. Trigger spray gun to bleed air out of hose.
7. When paint reaches spray tip, spray a test area to
check spray pattern. See Figure 23.
8. Use the lowest pressure setting necessary to get a
good spray pattern. If pressure is too high, material is
over-atomized. If pressure is too low, tailing will
appear or paint will spatter out in gobs rather than in
a fine spray. See Figure 24. Most latex paints and
stains will require very high pressure, which is why the
sprayer is built to deliver up to 2,500 psi when needed.
