  • Page 7: A Comparison: Conventional Versus Hvlp Spray Guns

    FIGURE 2 Fluid Outlet (39) Air Inlet Connector (36) Safety Valve (2) Fluid Flow Knob (11) Air Regulator (24) Air Outlet Connector (36) 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.

  • Page 8: Preparation

    IMPORTANT: Before using for the first time, the spray gun must be cleaned using a solvent based thinner. If not removed, the red oil used by the manufacturer for testing and corrosion protection may contaminate paint. IMPORTANT: The Spray Gun must be cleaned immediately after use. Improper cleaning is a common reason for the Spray Gun not to work.
  • Page 9 Pattern Adjustment Warning!! Never exceed the Maximum Inlet PSI of 70 PSI. Remember that the air pressure feeding the gun should be set to 10-30 PSI, using the Air Regulator (24). To set the pattern size specific to the job, use the Pattern Control Knob (65) (see FIGURE 1 on page 6).

  • Page 10: Techniques

    Note: Before spraying, mask all objects you do not want sprayed and lay cloths (not included) on the floors. Always keep the gun at right angles to the workpiece (See FIGURE 7). Pull the Trigger (52) slowly and move the Spray Gun in parallel strokes to the object being painted. Keep the distance from the object being painted at 6”...

  • Page 11: Maintenance

    Always follow the paint manufacturer’s recommendations for cleaning, solvent type, and disposing of used solvent. Latex Paints: Use warm, soapy water. IMPORTANT: Do not use mineral spirits on latex paints or the mixture will congeal making it very difficult to remove. Oil Based Paints: Use mineral spirits.
