- Connect the power cord to a suitable grounded electrical outlet (50 Volts, as per specifications).
5. Operating Instructions
5.1 Initial Start-up
- Ensure the power cord is securely plugged in.
- Turn the compressor ON using the power switch. The compressor will begin to fill the tank with air.
- Monitor the tank pressure gauge. The compressor will automatically shut off once the maximum pressure (8 bar) is reached.
5.2 Adjusting Output Pressure
The compressor features a regulator to adjust the output air pressure for your tools.
- Connect your air tool to the quick-connect coupler.
- Turn the red pressure regulator knob clockwise to increase pressure and counter-clockwise to decrease pressure.
- Observe the outlet pressure gauge to set the desired working pressure for your tool.

5.3 Shutting Down
- Turn the compressor OFF using the power switch.
- Disconnect any air tools.
- Bleed any remaining air pressure from the tank by opening the drain valve or using an air tool until the tank pressure gauge reads zero.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your compressor. Always disconnect the power before performing any maintenance.
6.1 Draining Condensation
Moisture accumulates in the air tank during operation. This condensation must be drained regularly to prevent corrosion and maintain air quality.
- Ensure the tank pressure is at zero.
- Locate the drain valve at the bottom of the air tank.
- Open the drain valve slowly to release any accumulated water. Close the valve once all water has been drained.
- Perform this procedure after each use or at least daily if used frequently.

6.2 Cleaning
- Wipe down the exterior of the compressor with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Keep the air intake vents clear of dust and debris to ensure proper cooling.
6.3 Oil-Free Design
This compressor features an oil-free pump, eliminating the need for oil checks and changes. This simplifies maintenance and reduces the risk of oil contamination in the air supply.
