Dual-Action Airbrush Operation
The dual-action airbrush provides precise control over both air and paint flow:
- Air Flow Control: Press the trigger down to release air.
- Paint Flow Control: While holding the trigger down, pull it back to release paint. The further you pull back, the more paint is released.
Practice on a scrap surface to get a feel for the air and paint flow before working on your main project. This allows for fine detail work and broader coverage by adjusting the trigger and air knob.

Maintenance
Proper cleaning and maintenance are crucial for the longevity and optimal performance of your airbrush kit. Always clean your airbrush immediately after use, especially if changing colors or if the kit has been inactive for more than ten minutes, to prevent clogging.
Cleaning Steps:
- Empty Paint Cup: Remove any remaining paint from the capacity cup.
- Rinse: Add a small amount of appropriate cleaning solution (water for water-based paints, or specific airbrush cleaner for other types) to the cup.
- Back-flush: Cover the nozzle with your finger or a cap and gently pull back the trigger. This will force air back into the cup, bubbling the cleaning solution and helping to dislodge paint.
- Spray Out: Spray the cleaning solution through the airbrush until it runs clear.
- Disassemble and Deep Clean: For thorough cleaning, disassemble the airbrush gun. Use the provided cleaning brushes and washing needles to clean the nozzle, needle, and paint channel. Pay close attention to the smallest parts.
- Lubricate (Optional): After cleaning and drying, apply a tiny drop of airbrush lubricant to the needle packing and trigger mechanism to ensure smooth operation.
- Reassemble: Carefully reassemble the airbrush gun.
