Figure 7 - 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.
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 to
ensure the pattern size and consistency
are set correctly.
Operation
1. Begin spraying.
6 - 9 in.
Always keep
the gun at
right angles to
the work (See
Figure 8).
2. Keep the nozzle
about 6 to 9
inches from the
work surface
throughout the
stroke and
always keep the
gun in motion
while spraying. Stopping gun move-
ment 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 9).

4. 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.
5. Overlap strokes just enough to
obtain an even coat (See Figure 11).

NOTE: Two thin coats of paint will
yield better results and have less
chance of runs than one heavy layer.

Use masking tape to cover other
areas if needed.

quickly in the small passages rendering

removing hardened paint from the pas-

NOTE: In the instructions below, the use
of the word "solvent" refers to the spe-
cific solvent for the material used (exam-
ple: lacquer thinner for lacquer, etc.).
