Setup
- Connect Air Hose: Attach the 5-foot air hose to the air inlet on the airbrush handle and to your air source (e.g., air compressor or propellant can with regulator). Ensure connections are secure to prevent air leaks.
- Attach Propellant Regulator: If using a propellant can, screw the propellant regulator onto the can, then connect the air hose to the regulator.
- Prepare Fluid Bottle: Ensure the siphon tube is properly inserted into the fluid bottle and the airbrush attachment cover is securely fastened to the bottle.
- Attach Fluid Bottle: Screw the prepared fluid bottle onto the bottom of the airbrush body.
Operating Instructions
- Prepare Paint: Thin your paint to a milk-like consistency suitable for airbrushing. Use the included 2 cc paint dropper to transfer paint into the fluid bottle.
- Adjust Air Pressure: For optimal performance, set your air source pressure between 15-50 PSI. The propellant regulator allows for basic pressure adjustment if using a can.
- Test Spray: Before applying to your project, test the spray pattern on a scrap surface. Hold the airbrush approximately 1/4" to 1-1/2" from the surface for a broad spray pattern.
- Spraying Technique:
- Press the ergonomic trigger to release air and paint simultaneously.
- Move the airbrush in smooth, even strokes across your desired surface.
- Maintain a consistent distance and speed for uniform coverage.
- This is a single-action airbrush, meaning air and paint flow are controlled by a single trigger press.
- As an external mix airbrush, paint mixes with air outside the airbrush body, making it suitable for thicker paints and easier cleaning.
- Applications: This airbrush is suitable for watercolors, acrylics, inks, dyes, automotive urethanes, lacquers, and enamels. Common applications include general airbrushing, hobbies, crafts, models, signs, backgrounds, and T-shirts.

Maintenance
Proper cleaning and maintenance are crucial for the longevity and performance of your airbrush.
- Immediate Cleaning: After each use, empty any remaining paint from the fluid bottle. Fill the bottle with an appropriate cleaning solution (e.g., airbrush cleaner, water for water-based paints, thinner for solvent-based paints) and spray it through the airbrush until clear.
- Disassembly for Deep Cleaning:
- Unscrew the fluid bottle.
- Carefully unscrew the nozzle cap, fluid nozzle, and remove the needle from the front of the airbrush.
- Clean all components with a brush and appropriate cleaning solution. Pay special attention to the needle, fluid nozzle, and nozzle cap to remove all paint residue.
- Caution: The needle and fluid nozzle are delicate. Handle with care to avoid bending or damage.
- Reassembly: Once all parts are clean and dry, carefully reassemble the airbrush in reverse order. Ensure all connections are snug but do not overtighten.
- Storage: Store your airbrush in its case or a clean, dry place to protect it from dust and damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No paint flow or inconsistent spray | Clogged nozzle/needle, improperly thinned paint, insufficient air pressure, loose fluid bottle connection. | Clean nozzle/needle, thin paint properly, increase air pressure (within 15-50 PSI range), ensure fluid bottle is securely attached. |
| Air bubbles in fluid bottle | Loose fluid nozzle, damaged fluid nozzle, siphon tube not fully submerged. | Tighten fluid nozzle, inspect for damage and replace if necessary, ensure siphon tube reaches the bottom of the bottle. |
| Paint leaks from nozzle area | Loose nozzle cap or fluid nozzle, damaged O-rings. | Tighten components, inspect and replace O-rings if worn. |
