2. Safety Information
Always observe the following safety precautions to prevent injury or damage to the equipment:
- Electrical Safety: Ensure the power supply matches the compressor's voltage (220-240V/50Hz). Do not operate with damaged cords or plugs. Keep the compressor away from water or damp environments.
- Pressure Safety: Never exceed the maximum operating pressure. Do not tamper with the safety valve. Always release air pressure from the tank before disconnecting hoses or performing maintenance.
- Ventilation: Operate the compressor in a well-ventilated area to prevent overheating and ensure proper air intake.
- Children and Pets: Keep the compressor out of reach of children and pets. This is not a toy.
- Intended Use: Use the compressor only for its intended purpose of supplying air for airbrushing.

4. Setup Instructions
- Unpacking: Remove the compressor and all accessories from the packaging. Inspect for any visible damage.
- Positioning: Place the compressor on a stable, level surface in a well-ventilated area. Ensure there is adequate space around the unit for airflow, especially for the cooling fans.
- Attach Pressure Regulator: Screw the output pressure regulator (with filter and gauge) onto the air outlet port of the compressor. Ensure it is hand-tightened securely to prevent air leaks.
- Connect Air Hose: Connect your airbrush hose to the output port of the pressure regulator.
- Power Connection: Plug the power cable into a suitable electrical outlet (220-240V/50Hz).

5. Operating Instructions
- Power On: Flip the power switch to the 'ON' position. The compressor will begin to fill the air tank.
- Automatic Operation: The compressor will automatically stop when the pressure reaches approximately 4.50 bar (67.50 PSI) and restart when the pressure drops to approximately 3.50 bar (42.50 PSI). This maintains a consistent air supply.
- Adjusting Output Pressure: Use the knob on the pressure regulator to adjust the desired output air pressure for your airbrush. The pressure gauge will display the current output pressure.
- Begin Airbrushing: Once the desired pressure is set, you can begin using your airbrush.
- Power Off: After use, turn off the compressor by flipping the power switch to the 'OFF' position.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your compressor.
- Drain Air Tank: Moisture can accumulate in the air tank. Regularly drain the tank by opening the drain valve located at the bottom of the tank. Do this after each use or at least weekly, depending on humidity and usage frequency. Ensure the compressor is off and depressurized before draining.
- Clean Water Trap: The water trap (part of the pressure regulator) collects moisture and debris. Periodically unscrew the bottom of the water trap to empty accumulated water. Clean the filter element if necessary.
- General Cleaning: Keep the exterior of the compressor clean and free of dust. Ensure the cooling fan vents are not obstructed. Use a dry cloth for cleaning.
- Cooling Fans: The compressor features dual cooling fans. Ensure these fans are clear of obstructions to maintain efficient cooling during operation.

7. Troubleshooting
If you encounter issues, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not turn on | No power supply; Power switch off; Thermal overload protection activated | Check power connection; Turn power switch on; Allow compressor to cool down (if overheated) |
| No air output or low pressure | Air hose disconnected or leaking; Regulator knob closed; Water trap full; Airbrush clogged | Check hose connections; Adjust regulator knob; Drain water trap; Clean airbrush nozzle |
| Compressor runs continuously | Air leak in system; Pressure switch malfunction | Check all connections for leaks; Contact customer support if pressure switch is faulty |
| Excessive noise or vibration | Loose components; Compressor not on a level surface | Check for loose screws; Ensure compressor is on a stable, level surface |
