6. Operating Instructions

6.1 Tire Inflation (Air Compressor Function)

1. Connect: Attach the air hose with the correct nozzle to the tire valve. Ensure a tight connection to prevent air leakage.
2. Power On: Press the power button to turn on the device. The digital display will show the current tire pressure.
3. Select Mode: Press the mode button to cycle through different inflation modes (e.g., car, motorcycle, bicycle, ball). Each mode may have a default pressure unit (PSI, BAR, KPA, KG/CM²).
4. Set Target Pressure: Use the '+' and '-' buttons to set your desired target pressure. Refer to your vehicle's manual or tire sidewall for recommended pressure.
5. Start Inflation: Press the power button again to start the compressor. The device will automatically stop once the target pressure is reached.
6. Disconnect: Carefully disconnect the nozzle from the tire valve. A small amount of air may escape, which is normal.

Note: For car tires, the default BAR unit in car mode might be unfamiliar. You can switch to bicycle mode to set pressure in PSI if preferred, then inflate your car tire.

6.2 Jump Starter Function
