Model H7669 HVLP Spray Gun -11-
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 sag-
ging.
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 at all times when
spraying as shown in Figure 4. Do not
allow your wrist to bend. This will cause
the gun to arc across the surface and
distribute the material unevenly, pos-
sibly creating sags and dry spots.
10. Begin spraying 2-3 inches before the
work and continue to the end of the
work. Continue the motion for a few
inches past the work until you are
ready for the return stroke.
11. Maintain an even speed when spray-
ing.
12. Overlap each stroke by 50%. This will
ensure even coverage as shown in
Figure 5. Less than 50%, as shown
in the figure to the right, may lead to
missed spots or streaky results.
NOTICE
Tipping spray gun may cause material
to spill out of the cup. Always hold
the spray gun perpendicular to the
ground to avoid potential spills and
gravity feed problems.
