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.
