3. Turn fluid control knob fully clock-
wise until closed (See Figure 8).
4. Trigger a short burst while turning
fluid control knob counterclockwise.
Observe the spray pattern on the tar-
get and adjust the fluid control knob
until the desired pattern (atomiza-
tion) is obtained (See Figure 9).

Figure 9 - Pattern Consistency
(Atomization)
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.
If the spray is too coarse (spitting globs),
reduce the amount of material with the
fluid control knob or thin the paint.
PRESSURE FEED SET-UP
1. Adjust air pressure to the spray gun
according to the recommendations sup-
plied with the spray material. This air
pressure usually falls between 40 - 60
psi. Adjust air pressure with the trigger
pulled and air control knob (if applica-
ble) fully open. If reduced air pressure is
desired for some areas of the spray job,
use air control knob to reduce pressure
as necessary (See Figure 7).
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 8).
3. Open the fluid control knob by turning
counterclockwise about three turns.
4. Start the tank pressure at 0 psi and
turn the tank regulator slowly to
increase fluid delivery until the
desired pattern consistency (atomiza-
tion) is reached.
5. If the atomization is too coarse,
reduce the tank pressure with the
tank regulator. Trigger a short burst
or open relief valve to relieve the
pressure, then increase pressure
slowly to obtain proper pattern con-
sistency (See Figure 9).
6. The fluid control knob can be used to
finely adjust pattern consistency.
Before spraying the workpiece, practice
a few minutes on a cardboard target to
ensure the pattern size and consistency
are set correctly.
Operation
1. Begin spray-
ing. Always
keep the gun at
right angles to
the work (See
Paint too
Figure 10).
coarse
Keep the nozzle
about 6 to 9 inches
from the work
surface through-
out the stroke
and always keep
the gun in motion
while spraying.
Stopping gun
movement in mid-stroke will cause a
build up of paint and result in "runs."
Do not "fan" the gun from side to side
while painting. This will cause a build-up
of paint in the center of the stroke and
an insufficient coating at each end (See
Figure 11).

2. "Trigger" the gun properly. Start
the gun moving at the beginning
of the stroke BEFORE SQUEEZING
THE TRIGGER and release the trigger
BEFORE STOPPING GUN MOVEMENT
at the end of the stroke. This pro-
cedure will "feather" (blend) each
stroke with the next without showing
overlap or unevenness (See Figure 12).

3. The amount of paint being applied
can be varied by the speed of the
stroke, distance from the surface and
adjustment of the fluid control knob.
4. Overlap strokes just enough to
obtain an even coat (See Figure 13).
NOTE: Two thin coats of paint will
yield better results and have less
chance of runs than one heavy layer.

5. Use a piece of cardboard as a shield
to catch overspray at the edges of
the work to protect other surfaces.
Use masking tape to cover other
areas if needed.
Maintenance
DAILY CLEAN-UP
Local codes may require specific clean-
ing methods and equipment. Follow
local codes and manufacturer's recom-
mendations for the use and disposal of
spray materials and solvent.
Clean spray gun
immediately after
use. Paint and other material dry quickly
in the small passages rendering gun use-
less due to the difficulty of removing
hardened paint from the passages inside
the gun.
