4. Operation
The Apollo 7500 AtomiZer has a unique and simple fan pattern control. Locate
the Fan Adjustment Ring. Turn the spray gun on its side and notice the fan
size indicator stamped into the spray head casting, just to the right of the fan
adjustment ring. You will notice that there is a “-” sign at the top and a “+” sign
at the bottom with two arrows indicating the direction of rotation. Rotating the
ring UPWARD will begin to reduce the size of the fan pattern until the pattern
is round. Rotating the ring DOWNWARD will provide a full, open, wide pattern.
(Relative to the distance the spray gun is held from the work surface). To adjust
the direction of the fan pattern, loosen the air cap ring, (#1, page 33) rotate the
air cap ears (#2, page 33) to either a vertical or horizontal position as noted in
the diagram. This will provide your vertical or horizontal fan pattern.
4.1 Spray Patterns
Fig. 1 Use this position when spraying across from side
to side.
Fig. 2 Use this position when spraying from top to bottom.
Fig. 3 Use this position for spotting small objects, corners
and sharp angles.
Install the appropriate fluid nozzle, needle assembly and color coded air cap (A, B, C or D) for the viscosity of the fluid being
sprayed. See chart for recommendations (Section 4.5). Your spray gun is supplied with a 1.0mm Fluid Nozzle and Needle
Assembly paired with a “B” (Gold) air cap. Prepare coating. (Thinning if necessary). Filter and pour into spray gun. See chart.

Viscosity chart should be used as a guide to thinning various coatings. Actual reduction will depend upon model turbine
used, flow out properties of the coating and the final visual results of the sprayed work piece. Seconds quoted are measured
in a Zahn #2 Viscosity Cup.
