- Pressure Regulator & Gauge: Allows for real-time display and adjustment of air pressure.
- Moisture Filter: Ensures cleaner air delivery by trapping moisture.
- Twin Cylinder: Stronger and steadier air output.
4. Setup Instructions
Follow these steps to set up your Sparmax TC-620X compressor:
- Unpacking: Carefully remove all components from the packaging. Verify that all included items are present.
- Placement: Place the compressor on a stable, level surface in a well-ventilated area.
- Component Assembly:
- Attach the airbrush holders to the designated points on the compressor.
- Connect the braided air hoses to the compressor's air outlets and to your airbrushes.
- If necessary, use the provided airbrush adaptors to ensure compatibility with your airbrushes.
- Power Connection: Plug the power cord into a grounded 120 Volt electrical outlet.
- Initial Check: Before connecting an airbrush, turn on the compressor to ensure it builds pressure and the auto on/off switch functions correctly. The compressor should turn off around 60 psi and turn back on around 40 psi.

5. Operating Instructions
To operate your Sparmax TC-620X compressor:
- Power On: Flip the power switch to the "ON" position. The compressor will begin to fill the air tank.
- Pressure Adjustment: Use the pressure regulator knob to set the desired working pressure for your airbrush. The gauge will display the current pressure.
- Airbrush Connection: Connect your airbrush(es) to the air hoses. The compressor supports up to two airbrushes simultaneously.
- Begin Airbrushing: Once the desired pressure is set, you can begin your airbrushing work. The compressor's auto on/off feature will maintain consistent pressure.
- Power Off: After use, turn off the compressor by flipping the power switch to the "OFF" position.
- Release Pressure: Disconnect your airbrush and release any remaining air pressure from the system by briefly opening the airbrush trigger or using the tank drain valve.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your compressor:
- Drain Moisture Trap: After each use, or regularly depending on humidity, drain any accumulated moisture from the moisture trap and the air tank's drain valve. This prevents water from entering your airbrush and paint.
- Clean Exterior: Wipe down the exterior of the compressor with a damp cloth to remove dust and debris. Do not use harsh chemicals.
- Check Hoses and Connections: Periodically inspect air hoses for cracks or leaks and ensure all connections are secure.
- Storage: Store the compressor in a clean, dry environment when not in use.
- Oil-Free Design: The Sparmax TC-620X is an oil-free compressor, requiring no lubrication of internal components.
7. Troubleshooting
Refer to this section for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not turn on. | No power, power switch off, or thermal overload. | Check power cord connection and outlet. Ensure power switch is ON. Allow compressor to cool if it has been running for an extended period. |
| No air output or low pressure. | Air hose disconnected, pressure regulator set too low, or air leak. | Check all hose connections. Adjust pressure regulator. Inspect hoses and fittings for leaks. |
| Excessive moisture in air. | Moisture trap full or not drained. | Drain the moisture trap and air tank thoroughly. |
| Compressor runs continuously. | Air leak in system or faulty pressure switch. | Check for air leaks in hoses, connections, and airbrush. If problem persists, contact support. |
