4. Start the paint/cup tank pressure
at 0 psi and turn regulator slowly
to increase fluid delivery until
the desired pattern consistency
(atomization) 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
consistency (See Figure 7).

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. 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 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
coarse
each end (See Figure 9).
3. Trigger the gun properly. Start the
gun moving at the beginning of
the stroke BEFORE SQUEEZING

mOVEmENT at the end of the
stroke. This procedure will feather
(blend) each stroke with the
next without showing overlap or
unevenness (See Figure 10).
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.
6. 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.
