1. Place the Compressor: Position the compressor on a stable, flat surface in a well-ventilated area.
2. Connect Air Hose: Attach one end of the air hose to the air outlet on the compressor and the other end to the airbrush. Ensure connections are secure.
3. Connect Power: Plug the 12V DC power adapter into the compressor's power input, then plug the adapter into a suitable electrical outlet.
4. Install Moisture Separator (Optional): If desired, install the moisture separator between the compressor and the air hose to prevent moisture from reaching your paint.
5. Select Nozzle/Needle: Choose the appropriate nozzle and needle size (0.2mm, 0.3mm, or 0.5mm) for your project and install them into the airbrush. The 0.3mm nozzle is typically pre-installed.
6. Fill Paint Cup: Use the pipette to carefully fill the airbrush's paint cup with your desired airbrush-ready paint. Do not overfill.

6. Operating Instructions

Once set up, you can begin using your airbrush set:

1. Turn On Compressor: Press the power button on the compressor. The compressor will start automatically when pressure drops below 1 Bar and stop when it reaches 1.5 Bar.
2. Adjust Air Pressure: Use the rotary switch on the compressor to adjust the air pressure level. The indicator lights will show the current pressure setting.

3. Test Spray: Before applying to your project, perform a test spray on a scrap piece of material to check paint consistency and air pressure.
4. Airbrush Operation (Dual-Action):
   • Press down on the trigger to release air.
   • Pull back on the trigger to release paint.
   • Adjust the amount of paint by varying how far you pull back the trigger.
5. Painting: Maintain a consistent distance from your surface and use smooth, even strokes.
6. Finish Work: When finished, release the trigger, turn off the compressor, and disconnect the power.

7. Maintenance and Cleaning

Regular cleaning and maintenance are crucial for the longevity and optimal performance of your airbrush set.

1. Empty Paint Cup: After each use, empty any remaining paint from the cup.
2. Flush with Cleaner: Fill the paint cup with an appropriate airbrush cleaner or water (for water-based paints) and spray it through the airbrush until clear.
3. Disassemble Airbrush: Carefully disassemble the airbrush, removing the needle, nozzle, and air cap.
4. Clean Components: Use the provided cleaning brushes and needles to thoroughly clean all paint residue from the airbrush body, nozzle, needle, and paint cup. Pay special attention to the nozzle, as dried paint can easily clog it.
5. Reassemble: Once all parts are clean and dry, carefully reassemble the airbrush. Do not overtighten components.
6. Compressor Care: Wipe down the compressor exterior with a damp cloth. Ensure air vents are clear of dust.

8. Troubleshooting

If you encounter issues, refer to the following common problems and solutions:

• No Air Flow:
  • Check if the compressor is powered on and the power adapter is securely connected.
  • Ensure the air hose connections are tight.
  • Verify the airbrush trigger is pressed down.
• No Paint Flow or Splattering:
  • The nozzle or needle might be clogged. Clean thoroughly as per Section 7.
  • Paint might be too thick. Thin paint with appropriate reducer.
  • Needle might not be pulled back far enough.
  • Air pressure might be too low. Adjust pressure on the compressor.
• Compressor Not Starting/Stopping Automatically:
  • Ensure the air hose is securely connected and there are no leaks.
  • Check for any obstructions in the air intake or outlet.
• Air Leakage:
  • Tighten all connections (air hose to compressor, air hose to airbrush).
  • Check O-rings for damage and replace if necessary.
