3. Setup Instructions
- Unpack Components: Carefully remove all items from the packaging and inspect for any damage.
- Position Compressor: Place the TC-326T compressor on a stable, level surface in a well-ventilated area. Ensure adequate space around the unit for airflow.
- Connect Air Hose: Attach one end of the 6-foot air hose to the air outlet on the compressor's pressure regulator. Securely fasten the other end to the desired airbrush.
- Prepare Airbrush: Depending on the airbrush model (G22, S68, or E91), attach the appropriate fluid cup or siphon bottle.
- Add Paint: Pour the desired water-based acrylic paint into the airbrush's fluid cup or siphon bottle. If necessary, thin the paint using the included reducer for optimal flow and spray consistency.
- Power On: Plug the compressor into a standard electrical outlet. Turn on the compressor using the power switch. The compressor will build pressure and then automatically shut off when the tank is full. It will restart automatically when pressure drops during use.

4. Operating Instructions
Familiarize yourself with the operation of each airbrush type:
4.1. Dual-Action Airbrushes (Models G22, S68)
- Air Control: Press down on the trigger to release air.
- Paint Control: Pull back on the trigger to release paint. The further back you pull, the more paint is released.
- Spray Adjustment: Adjust the air pressure on the compressor's regulator for desired spray patterns. Practice on scrap material to achieve consistent results.
4.2. Single-Action Airbrush (Model E91)
- Air and Paint Control: Pressing the trigger releases both air and a fixed amount of paint simultaneously.
- Spray Adjustment: Paint flow is primarily controlled by adjusting the air pressure on the compressor and the paint's viscosity.
4.3. General Tips
- Always test your spray pattern and paint consistency on a test surface before applying to your project.
- Maintain a consistent distance from the surface for even coverage.
- Keep the airbrush moving to avoid paint buildup and overspray.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your airbrush kit.
5.1. Airbrush Cleaning
- After Each Use: Empty any remaining paint from the fluid cup/siphon bottle. Spray airbrush cleaner through the airbrush until it sprays clear.
- Deep Cleaning: Periodically disassemble the airbrush components (needle, nozzle, cap) and clean them thoroughly using the provided cleaning brushes and airbrush cleaner. Refer to the individual airbrush manuals for detailed disassembly instructions.
- Lubrication: Apply a small amount of airbrush lubricant to the needle and trigger mechanism as needed.
5.2. Compressor Maintenance
- Drain Moisture Trap: Regularly drain any accumulated moisture from the water trap filter on the compressor.
- Air Tank Drainage: Periodically drain the 3-liter air storage tank to remove any condensation. Consult the compressor manual for specific instructions.
- Filter Inspection: Check the air filter for cleanliness and replace if necessary.
6. Troubleshooting
Common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No air flow | Compressor off, hose disconnected, clogged airbrush. | Check power, reconnect hose, clean airbrush. |
| Inconsistent spray / Spattering | Paint too thick, clogged nozzle, low air pressure. | Thin paint, clean nozzle, increase air pressure. |
| No paint flow | Clogged nozzle/needle, empty paint cup, air cap loose. | Clean nozzle/needle, refill paint, tighten air cap. |
| Airbrush leaks | Loose components, damaged O-rings. | Tighten parts, inspect and replace O-rings. |
