Air Connection For best service you should incorporate a regulator and inline filter, as shown in the diagram above. Hoses, couplers, regulators, and filters are all available at Harbor Freight Tools. Note: Compressor pumps discharge condensed water, oil, or other contaminants along with the compressed air. Condensation causes “fish eyes” to appear in paint patterns. To avoid this problem, install water/oil removal filters and controls (not included) as close to the Spray Gun as possible.
Control Layout All of the instructions that follow referance part numbers for the larger spray gun. The small spray gun is assembled, operated and maintained the same way. During the following procedure, refer to the Assembly Drawing on page 14 and 15. FIGURE 1 Turn the Pattern Control Knob (7A) clockwise to adjust the paint / air mixture. Turn the Air Cap (1A) to produce vertical and horizontal spray patterns. Turn the Fluid Control Knob (13A) to change the size of the spray pattern.
IMPORTANT: The Spray Gun must be cleaned immediately after use. Improper cleaning is a common reason for the Spray Gun not to work. A Comparison: Conventional versus HVLP Spray Guns Because conventional spray guns require a much higher air cap pressure to atomize the paint than HVLP Spray Guns, conventional guns have lower transfer efficiencies and more overspray. This translates to a significant paint/material savings for HVLP guns, in addition to making them more environmentally friendly.
IMPORTANT: The Spray Gun must be cleaned immediately after use. Improper cleaning is a common reason for the Spray Gun not to work. Fan Direction and Pattern Adjustment Fan Direction To change the direction of the fan from horizontal to vertical, loosen the Lock Ring and turn the Air Cap (1A) 90 degrees. After the adjustment, tighten the Lock Ring by hand. See FIGURE 3 below.

IMPORTANT: The Spray Gun must be cleaned immediately after use. Improper cleaning is a common reason for the Spray Gun not to work. Techniques Note: Before spraying, mask all objects you do not want sprayed and lay cloths (not included) on the floors. 1. Always keep the gun at right angles to the workpiece (See FIGURE 6). Pull the Trigger (23A) slowly and move the Spray Gun in parallel strokes to the object being painted. Keep the distance from the object being painted at 6” to 9”.
IMPORTANT: The Spray Gun must be cleaned IMMEDIATELY after use. Improper cleaning is a common reason for the Spray Gun not to work properly. Materials dry quickly which will render the gun useless. It is extremely difficult to remove dry paint from small passages within the Gun. Maintenance SOLVENT SELECTION Always follow the paint manufacturer’s recommendations for cleaning, solvent type, and disposing of used solvent. Latex Paints: Use warm, soapy water.
