5. Setup and Operating Instructions
Follow these steps to properly set up and operate your tire inflator:
- Start the Car: Ensure your vehicle's engine is running to provide stable power to the inflator.
- Connect Power: Plug the power connector (cigarette lighter plug) into your car's 12V accessory socket.
- Attach Air Hose: Connect the air hose nozzle tightly to the tire valve stem. Press down the buckle to secure it.
- Set Desired Pressure: The dual display will show the current tire pressure. Use the '+' and '-' buttons to set your desired target pressure. Press the 'R' button to cycle through pressure units (PSI, BAR, KPA, kg/cm²).
- Start Inflation: Press the ON/OFF button to begin inflation. The inflator will automatically stop once the preset pressure is reached.
- Disconnect: Once inflation is complete, disconnect the air hose nozzle from the tire valve and unplug the power connector from the car's socket. Store the hose and cord in their designated compartments.
