Preparation
1. Thoroughly mix and thin paint in
accordance with the paint
manufacturer's instructions. Most
materials will spray readily if
thinned properly.
2 Strain material through cheese
cloth or a paint strainer.
3. Fill the canister about 3/4 full and
start the air compressor.
4. Set up a piece of cardboard or other
scrap material to use as a target and
adjust for best spray pattern.
5. Test the consistency of the material by
making a few strokes on a cardboard
target. If material still appears too
thick, add a small amount of thinner.
THIN WITH CARE!! Do not exceed
paint manufactuer's thinning
recommendations.
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 2). Hand tighten
lock ring after adjustment.

WATER/OIL IN COMPRESSED AIR
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.
Failure to install appropriate water/oil removal equipment
may result in damage to machinery or workpiece.
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
compressor regulator or air control
knob to reduce pressure as
necessary (See Figure 3).

2. Set pattern size to desired shape. For
full pattern, open pattern control
knob by turning counterclockwise.
For a round pattern, turn pattern
control knob clockwise (See Figure 4).

3. Turn fluid control knob fully
clockwise until closed (See Figure 4).
4. Trigger a short burst while turning
fluid control knob
counterclockwise. Observe the
spray pattern on the target and
adjust the fluid control knob until
the desired pattern (atomization) is
obtained (See Figure 5).

fine
Figure 5 - Pattern Consistency
(Atomization)
If the spray is too fine (excessive
overspray), caused by too much air for
the amount of paint being sprayed,
reduce the air pressure or open the
fluid control to spray more material.
Decrease
If the spray is too coarse (spitting globs),
Air Flow
reduce the amount of material with the
fluid control knob or thin the paint.
5. The fluid control knob can be used
to finely adjust pattern consistency.
Before spraying the workpiece, practice
a few minutes on
a cardboard
target toensure
the pattern size
and consistency
are set correctly.
Operation
1. Begin spraying.
Always keep
the gun at right
angles to the
work (See
Figure 6).
