3M Series 56, Series 57 Adjusting the Fluid Flow, Adjusting the Fan Pattern Size, Spray Technique

General Set Up and Spray Gun Use cont.

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.
