5. Operating Instructions
Setting Tire Pressure:
- Connect the thumb lock adapter securely to the tire valve stem. The digital display will show the current tire pressure.
- Press the 'R' button on the digital display to cycle through pressure units (PSI, BAR, kg/cm²). Select your desired unit.
- Use the '+' and '-' buttons to set your target tire pressure.
Inflation Process:
- Once the desired pressure is set, press the power button to start inflation.
- The compressor will automatically stop once the preset pressure is reached.
- During inflation, the pump may pause briefly (2-4 times for 1-2 seconds) to stabilize airflow and ensure accurate pressure readings. This is a normal function to prevent over-inflation.
- Disconnect the thumb lock adapter from the tire valve and store the hose and compressor properly.

7. Troubleshooting
Refer to the table below for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not turn on. | Loose power connection, dead vehicle battery, blown fuse. | Check battery clamp connections. Ensure vehicle engine is running. Check vehicle's 12V power outlet fuse. |
| Slow inflation. | Air leak in hose/connection, low vehicle battery voltage. | Ensure all connections are tight. Check hose for damage. Ensure vehicle engine is running. |
| Compressor overheats and shuts off. | Prolonged use, insufficient ventilation. | Allow the compressor to cool down for at least 15-20 minutes. Ensure it is operating in a well-ventilated area. |
| Inaccurate pressure reading. | Loose connection to tire valve, faulty gauge. | Ensure the thumb lock adapter is fully seated on the valve stem. Compare reading with a known accurate gauge. |
