Adjusting the Fan Pattern Size

The fan size is regulated by using the fan adjustment knob as noted in Fig. 2. 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, triggering the spray gun lightly, and maintaining a distance from your target of 2 to 4 inches (50-100 mm).

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 (Series 05-100) 6 to 8 inches (160-200 mm), (Series

05-300) 4 to 6 inches (100-160 mm) from the object being sprayed.

2.Use smooth, even strokes across the surface to be sprayed with 50% over-lap.

3.Paint using parallel strokes. This technique applies all coatings evenly without cross coating.

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.

You must lubricate the moving components after every cleaning the spray gun. Cleaning washes away the lubricants that protect the friction points. Use an appropriate lubricant such as petroleum jelly.

Do not point the spray gun up while cleaning it.

Do not immerse the spray gun in solvent.

Do not wipe the spray gun with a cloth soaked in solvent; ring out the excess.

Do not use metal tools to clean the air cap holes as this may scratch them; scratches can distort the spray pattern.

General System Maintenance

Relieve the pressure from the spray gun and cup before servicing.

1 Turn off the air supply to the spray gun.

2.Disconnect air line from the spray gun.

3.When using a 3M™ PPS™ cup, pull the trigger and invert spray gun

(fully open, not partially) to return unused material to spray gun cup.
