7. Adjust the fluid control knob to
start with a low volume of material
and keep the atomization as low
as possible. You will need to use a
combination of fluid control, inlet air
pressure, air flow control and stroke
speed to achieve the results you
want. Spray so the material wets out
nicely without running or sagging.
8. Use the pattern control knob to
adjust the spray fan to your desired
pattern.
9. Keep the gun tip perpendicular,
parallel, and 6-8" from the work (as
shown in
Figure 4) when spraying.
Do not allow your wrist to bend. This
will cause the gun to arc across the
surface and distribute the material
unevenly, possibly creating sags and
dry spots.
10. Begin spraying 2-3 inches before the
workpiece and continue to the end of
the workpiece. Continue the motion
for a few inches past the work until
you are ready for the return stroke.
11. Maintain an even speed when
spraying.
12. Overlap each stroke by 50%. This will
ensure even coverage, as shown in
Figure 5. Overlapping less than 50%,
as shown in the figure to the right,
may lead to missed spots or streaky
results.
