An exploded view showing the main components: spray gun body, gravity feed cup, air regulator with gauge, cleaning brush, and multi-size wrench.

Included Components:

  • HVLP Gravity Feed Air Spray Paint Gun (with 2.0mm nozzle)
  • 600cc Aluminum Cup with Lid
  • Metal Air Gauge/Regulator
  • Cleaning Brush
  • Multi-size Wrench for Assembly/Disassembly

Setup Instructions

Proper setup is crucial for optimal performance and safety.

1. Assembly

  1. Attach Air Regulator: Screw the metal air gauge/regulator onto the air inlet valve at the bottom of the spray gun handle. Ensure it is hand-tightened securely.
  2. Attach Gravity Feed Cup: Screw the 600cc aluminum cup onto the top of the spray gun body. Ensure a tight seal to prevent leaks.
  3. Connect Air Hose: Connect your air compressor hose to the air regulator. Ensure the connection is secure and leak-free.

2. Paint Preparation

  • Always refer to the paint manufacturer's instructions for recommended thinning ratios and suitable solvents.
  • Thoroughly mix and thin your paint to the appropriate viscosity. Inadequate thinning can lead to poor atomization and an uneven finish.
  • Filter Paint: Always filter your paint through a fine-mesh paint strainer before pouring it into the gravity feed cup. This prevents clogs in the nozzle and ensures a smooth finish.
  • Fill the gravity feed cup with the prepared paint, ensuring not to overfill. Secure the cup lid.

Operating Instructions

Achieve optimal results by understanding and utilizing the spray gun's adjustable controls.

1. Adjusting Controls

  • Air Pressure: Set the operating air pressure to 40 PSI using the integrated air gauge/regulator. The working pressure at the air cap should be around 10 PSI. Adjust as needed for different materials and desired finish.
  • Fluid Control Valve: Located at the rear of the gun, this knob controls the amount of paint flowing through the nozzle. Turn clockwise to decrease fluid flow, counter-clockwise to increase.
  • Spray Pattern Control Valve: Located on the side of the gun, this knob adjusts the shape of the spray pattern from a round spot to a wide fan. Turn clockwise for a narrower pattern, counter-clockwise for a wider pattern.
  • Test Spray: Before applying to your workpiece, always perform a test spray on a scrap piece of material to fine-tune your settings and ensure the desired pattern and coverage.

2. Spraying Technique

  • Maintain a consistent distance (typically 6-8 inches) from the surface.
  • Move the gun parallel to the surface in smooth, even strokes.
  • Overlap each pass by about 50% to ensure uniform coverage.
  • Release the trigger at the end of each stroke to avoid paint buildup.

Maintenance and Cleaning

Regular cleaning and maintenance will extend the life of your spray gun and ensure consistent performance.

1. Disassembly for Cleaning

  1. Disconnect the air supply.
  2. Empty any remaining paint from the cup.
  3. Remove the gravity feed cup.
  4. Unscrew the air cap and fluid nozzle. Use the provided multi-size wrench if necessary, but be careful not to overtighten during reassembly.
  5. Remove the fluid needle by loosening the fluid control knob and pulling the needle out from the rear.

2. Cleaning Procedure

  • Use appropriate cleaning solvent (e.g., paint thinner for oil-based paints, water for water-based paints).
  • Clean all disassembled parts thoroughly using the provided cleaning brush. Pay special attention to the air cap, fluid nozzle, and fluid needle to remove all paint residue.
  • Clean the inside of the paint cup.
  • Never use metal objects to clean the nozzle or air cap holes, as this can damage them.
  • Rinse all parts with clean solvent/water.

3. Lubrication and Storage

  • Apply a small amount of spray gun lubricant to the fluid needle packing and air valve packing before reassembly.
  • Reassemble the gun, ensuring all parts are correctly seated and tightened. Do not overtighten.
  • Store the spray gun in a clean, dry place.
