Setup
- Unpack Components: Carefully remove all items from the packaging. Verify that all parts listed in the packing list are present.
- Assemble Nozzle Set: Choose the desired nozzle size (0.2mm, 0.3mm, or 0.5mm). Ensure the corresponding needle, nozzle, and nozzle cap are correctly assembled onto the airbrush.
- Connect Air Hose: Attach your air compressor hose to the airbrush's hose connector. If your kit includes a quick disconnect coupler, install it for convenience.
- Prepare Paint: Dilute your paint to a skim milk or light cream consistency. Test the consistency on a palette or scrap surface before loading it into the fluid cup.
- Fill Fluid Cup: Use the eye dropper to carefully fill the 7cc gravity fluid cup with your prepared paint.
Operating Instructions
The Neoeco airbrush features a dual-action trigger for precise control over both air and paint flow.
- Activate Air: Press the main lever down to activate the airflow.
Figure 5: Pressing the lever down to activate air. - Activate Paint: While holding the lever down for air, pull the lever backwards to activate paint flow. The further back you pull, the more paint is released.
Figure 6: Pulling the lever backwards to activate paint. - Adjust Fluid Control: Use the preset fluid control knob at the rear of the airbrush to limit how far the trigger can be pulled back. This allows for consistent paint flow for fine lines or specific effects.
- Spray Angle: The divergent cap provides a wider paint spray angle, approximately 55 degrees, for broader coverage.

First Exercise
For beginners, practicing basic strokes is essential:
- Dots, Lines, and Dashstrokes: Practice creating consistent dots, straight lines, and varied dashstrokes on a practice surface.
- First Project: Once comfortable with basic control, embark on a simple airbrush project to apply your skills.

Maintenance and Cleaning
Regular cleaning is crucial for optimal airbrush performance and longevity. The cut-away handle design facilitates easy cleaning of air passages.
- Immediate Cleaning: After each use, especially when changing colors or finishing a session, flush the airbrush with an appropriate cleaning solution or water.
- Disassembly: For thorough cleaning, carefully disassemble the airbrush components, including the fluid cup, nozzle cap, nozzle, needle, and handle.
- Component Cleaning: Clean each component thoroughly using a soft brush and appropriate cleaning solution or airbrush cleaner. Pay special attention to the needle, nozzle, and fluid passages to remove all paint residue.
- Reassembly: Ensure all parts are dry before reassembling. Carefully insert the needle, making sure it is properly seated and tightened.

Troubleshooting
Common Issues and Solutions
| Problem | Cause | Solution |
|---|---|---|
| Not Spraying | Loose needle secure nut | Ensure the needle is properly inserted and tightened. |
| Improper air pressure | Ensure your air compressor provides sufficient pressure. | |
| Paint too thick | Dilute paint to skim milk or light cream consistency. Test on a scrap surface. | |
| Clogged nozzle | Disassemble and clean all components thoroughly with cleaning solution. | |
| Bubbling in Fluid Cup | Loose nozzle cap or air cap | Ensure nozzle cap is finger tight; tighten air cap with wrench if needed. |
| Improper nozzle to body connection | Remove and reinsert nozzle. Apply thread sealer if scratches are present. | |
| Cracked or damaged nozzle | Replace nozzle. | |
| Incorrectly seated needle depth | Remove and reinsert needle to adjust. | |
| Skipping | Paint dried on needle tip/nozzle blockage | Disassemble and clean nozzle & needle thoroughly. |
| Paint too thick | Thin or strain paint to skim milk consistency. | |
| Dirty airbrush | Perform a deep cleaning of the airbrush. | |
| Cracked or damaged nozzle | Replace nozzle. | |
| Spattering | Dried paint on needle tip/nozzle blockage | Disassemble and clean nozzle & needle thoroughly. |
| Paint build up in needle cap | Clean needle with cotton swab dipped in appropriate cleaner. | |
| Air pressure too low | Gradually increase air pressure until desired spray pattern is achieved. | |
| Paint too thick | Thin or strain paint to skim milk consistency. | |
| Grainy or Textured Spray | Dried paint on needle tip/nozzle blockage | Disassemble and clean nozzle & needle thoroughly. |
| Paint too thick | Thin or strain paint to skim milk consistency. | |
| Air pressure too low | Gradually increase air pressure until desired spray pattern is achieved. | |
| Bad quality paint | Use high-quality paints from reputable manufacturers. | |
| Uneven surface | Sand surface if necessary; apply suitable primer or base coat. | |
| Spidering | Paint is too thin or watery | Thin or strain paint to skim milk consistency. |
| Air pressure too high | Adjust pressure to a lower, more suitable level. | |
| Holding airbrush too close or at incorrect angle | Maintain appropriate distance and angle for desired effect. | |
| Paper Bucking | Applying too much paint in one area | Apply light, even coats; allow each layer to dry. |
| Paper too thin | Choose heavier or thicker paper suitable for airbrushing. | |
| Too close to the surface | Maintain a suitable distance. |
Repair Procedures
- Broken Nozzle / Nozzle Threads Stuck:
If a nozzle breaks or its threads become stuck, use a small reamer tool to carefully unscrew and remove the broken part from the airbrush body.
- Bent Needle Repair:
- Step 1: Find a nickel coin or a similar object with a sharp, clean edge.
- Step 2: Place the bent needle on a flat surface. Using the flat part of the nickel, gently roll it along the length of the needle, applying light pressure. This helps identify remaining bends.
- Step 3: Apply gentle pressure and gradually roll the nickel to straighten out the bend. Continue this process until the needle is uniformly straight.
User Tips
- Air Compressor Requirement: This airbrush is pneumatic and requires an external air compressor to operate. Ensure your compressor can provide consistent and sufficient air pressure for your desired application.
- Paint Consistency is Key: Always dilute your paint to a consistency similar to skim milk or light cream. Testing on a scrap surface before applying to your project can prevent issues like clogging or uneven spray.
- Regular Cleaning: Frequent and thorough cleaning after each use, especially when switching colors, will prevent clogs and maintain optimal performance.
- High-Quality Paints: For best results and to minimize troubleshooting, use high-quality paints from reputable manufacturers.
