- Use the mode button (M/U) to select the desired inflation mode (car, motorcycle, bicycle, ball, or custom). Long press M/U to switch between BAR/KPA/PSI units.
- Use the '+' and '-' buttons to set your target pressure.
- Press the power button to start inflation. The compressor will automatically shut off once the preset pressure is reached.
