Model W1798 Professional Spray Gun

Often many spray pattern or spatter
problems can be solved by making sure
that the atomizing cap holes (
Figure
8) are kept clean. However, when
cleaning, do not use metal tools or you
may increase the diameter of the preset
holes. It is better to soak the cap in
paint thinner and use a wooden or plastic
toothpick.

To help eliminate drips and sagging
in the painted workpiece surface, the
atomizing cap needs to be adjusted so
your paint gun stroke is perpendicular to
the spray pattern. For example,
Figure
6 shows the atomizing cap position for a
horizontal spray pattern using a vertical
stroke of the paint gun. You can adjust
the atomizing cap to position the spray
pattern at any orientation, but just make
sure to keep the stroke of the paint gun
perpendicular to the spray pattern for
best results.

To minimize overspray and save paint,
you can adjust the pattern control knob
so the pattern shape falls between a fan
and a round spot pattern (see
Figures 6
and 7).
