5. Test the consistency of the material
by making a few strokes on a card-
board target. If material still
appears too thick, add a small
amount of thinner. THIN WITH
CARE!! Do not exceed paint manu-
factuer's thinning recommenda-
tions.
FAN DIRECTION
The direction of the fan (horizontal or
vertical) can be changed by loosening
the lock ring and turning the air cap 90
degrees (See Figure 3). Hand tighten
lock ring after adjustment.

PATTERN ADJUSTMENT
1. Adjust air pressure to the spray gun
according to the recommendations
supplied with the spray material.
This air pressure usually falls
between 40 - 60 psi.
Do not exceed

spray gun maxi-
mum pressure.
Adjust air pressure with the trigger
pulled and air control knob (if
applicable) fully open. If reduced air
pressure is desired for some areas
of the spray job, use the air com-
pressor regulator or air control
knob to reduce pressure as neces-
sary (See Figure 4).

All compressor pumps discharge some condensed water, oil or contaminates with
the compressed air.
IMPORTANT: This condensation will cause "fish eyes" to appear in the paint
job. Install appropriate water/oil removal equipment and controls as necessary
for the intended application. Locate filter as close to spray gun as possible.
NOTICE
2. Set pattern size to desired shape.
For full pattern, open pattern con-
trol knob by turning counterclock-
wise. For a round pattern, turn pat-
tern control knob clockwise
(See Figure 6).
3. Turn fluid control knob fully clock-
wise until closed (See Figure 6).

the target and adjust the fluid con-
trol knob until the desired pattern

Failure to install appropriate water/oil removal equipment
may result in damage to machinery or workpiece.
Figure 7 - Pattern Consistency
If the spray is too fine (excessive over-
spray), caused by too much air for the
amount of paint being sprayed, reduce
the air pressure or open the fluid con-
trol to spray more material.
Fluid control
If the spray is too coarse (spitting
knob
globs), reduce the amount of material
with the fluid control knob or thin the
paint.

Before spraying the workpiece, practice
a few minutes on a cardboard target to
ensure the pattern size and consistency
are set correctly.
