Setup

1. Unpacking: Carefully remove all components from the packaging. Verify that all included items are present: 1 spray gun, 1 paint cup, 1 tool kit (which typically includes cleaning brushes and a wrench).
2. Assembly:
   • Attach the paint cup to the top of the spray gun by screwing it into place. Ensure it is securely fastened to prevent leaks.
   • Connect your air compressor hose to the 1/4" air inlet at the bottom of the gun handle. Ensure a tight, leak-free connection.
3. Prepare Paint:
   • Ensure your paint is properly thinned according to the paint manufacturer's recommendations for spray application. Improper thinning can lead to poor atomization or clogging.
   • Strain the paint to remove any impurities or particles that could clog the nozzle.
   • Pour the prepared paint into the 600CC plastic cup.
4. Adjust Air Pressure: Connect the spray gun to an air compressor. Set the operating pressure between 28.8-51 PSI. The working pressure should be less than 10 PSI (HVLP).

Operating Instructions

Before painting, always test the spray pattern on a scrap piece of material to fine-tune settings.

1. Adjusting Controls:
   • Fluid Control Knob: Adjusts the amount of paint flowing through the gun. Turn clockwise to decrease flow, counter-clockwise to increase.
   • Pattern Control Knob: Adjusts the shape of the spray pattern (from round to fan). Turn to achieve the desired pattern width (7.0''-10.9'').
   • Air Volume Control Knob: Located at the bottom of the handle, this controls the air flow to the gun.
2. Spraying Technique:
   • Hold the gun perpendicular to the surface, maintaining a consistent distance (typically 6-8 inches).
   • Use smooth, even strokes, overlapping each pass by about 50%.
   • Release the trigger at the end of each stroke to avoid paint buildup.
   • Apply multiple thin coats rather than one thick coat to prevent runs and sags.

Maintenance and Cleaning

Proper cleaning after each use is crucial for the longevity and performance of your spray gun.

1. Empty Paint Cup: Remove any remaining paint from the cup.
2. Initial Rinse: Pour a small amount of appropriate cleaning solvent (e.g., paint thinner for oil-based paints, water for water-based paints) into the cup. Spray the solvent through the gun into a waste container until the spray runs clear.
3. Disassembly:
   • Unscrew and remove the air cap and fluid nozzle using the provided wrench.
   • Carefully remove the needle.
4. Thorough Cleaning:
   • Use the small cleaning brushes provided to clean the inside of the paint cup, fluid passages, air cap, nozzle, and needle.
   • Pay special attention to the air cap holes and the fluid tip opening to ensure no paint residue remains.
   • Do not use metal objects to clean the nozzle or air cap, as this can damage the precision openings.
5. Drying: Once everything is clean, use compressed air to blast out any lingering water or solvent from the passages. Leave the gun disassembled to dry completely before reassembly or storage.
6. Lubrication: Apply a small amount of spray gun lubricant to the needle packing and trigger pivot points periodically to ensure smooth operation.
