Adjusting the Fluid Flow
The adjustable fluid control is located at the rear of the
spray gun (if equipped). As a starting point, gently turn
the knob clockwise until you have very little needle
travel. Do not over-tighten. After the needle travel has
stopped, further tightening will only serve to compress
the spring and will not aid in adjustment. Next turn the
knob counterclockwise two full turns. These adjustment
procedures will serve only as a starting point. Fine
tuning of these adjustments will be based on your
material and technique.
Adjusting the Fan Pattern Size
The fan adjustment screw is located at the top of the
Series 52 and Series 55 models, and the fan is adjusted
by remote on the Series 56 and Series 57. As a starting
point, gently turn the knob clockwise until you feel no
further adjustment. Next, turn the knob counter-clockwise
one full rotation. The fan adjustment will allow you to
spray from a small round to a full fan pattern. The pattern
can also be changed from vertical to horizontal by rotating
the air cap a ¼ turn.
Note: The small round pattern can be achieved by
closing down the fan adjustment.
Spray Technique
1. To achieve the best results when spraying material,
keep the spray gun perpendicular to the surface and
maintain a consistent distance of approximately 6 to 8
inches (160-200 mm) from the object being sprayed.
2. Apply coating with 50% overlap to achieve an even
finish.
Note: Your spray gun may be made from aluminum
and may contain aluminum components. Certain
solvents containing Methylene Chloride and
Tricloromethane are not chemically compatible with
aluminum.
Read, understand and follow all safety statements
as well as wear appropriate, approved personal
protective equipment per the applicable MSDS and
material container labels for cleaning solutions.
