14. Check for damaged parts. Before using any tool, any part that appears damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment and binding of moving parts; any broken parts or mounting fixtures; and any other condition that may affect proper operation. Any part that is damaged should be properly repaired or replaced by a qualified technician. Do not use the tool if the trigger does not operate properly. 15. Replace

26. Spraying hazardous materials may result in serious injury or death. Do not spray pesticides, acids, corrosive materials, fertilizers, and toxic chemicals. 27. WARNING: The brass components of this product contain lead, a chemical known to the State of California to cause birth defects (or other reproductive harm). (California Health & Safety Code § 25249.5, et seq.) Note: Performance of the compressor (if powered by line voltage) may vary depending on variations in local line voltage. Exte

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. I

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. This translates to a significant paint/material savings for HVLP guns, in addition to making them more environmentally friendly. T

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. Preparation Note: Proper paint material mixture helps to ensure less problems. Be sure to follow the manufacturer’s directions. Most materials w

Pattern Adjustment Warning!! Never exceed the Maximum Inlet PSI of 70 PSI. 1. Remember that the air pressure feeding the gun should be set to 10-30 PSI, using the Air Regulator (24). 2. To set the pattern size specific to the job, use the Pattern Control Knob (65) (see FIGURE 1 on page 6). By turning it counterclockwise (all the way open), the pattern will flatten. Turn the Pattern Control Knob (65) clockwise for a round pattern. See FIGURE 5 below. FIGURE 5 Flat/Open Round/Closed 3. Open the

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 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” to 9”. This may slightly differ depending on the flow adjustment and the material being sprayed. Do not stop the gun movement while spraying. If you

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. 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. IF A FLAMMABLE SOLVENT NEEDS TO BE USED, ADHERE TO THE FOLLOWING: 1. Follow all of the solvent manufacturer’s clean up instructions and safety precautions at a
