This image also provides guidance on checking recommended tire pressure from a car owner's manual or door sticker, and suggests pressure ranges for sedans/MPVs and SUVs in summer and winter.
5. Setup
- Connect Power: Plug the 12V power cable into your vehicle's cigarette lighter socket. For optimal performance and to prevent battery drain, it is recommended to start your vehicle's engine.
- Attach Air Hose: Screw the air hose connector onto the valve stem of the item you wish to inflate. Ensure a tight seal to prevent air leakage.
- Select Nozzle (if applicable): For items other than standard car tires (e.g., bicycles, balls, air mattresses), select the appropriate nozzle adaptor and attach it to the air hose connector before attaching to the item's valve.
6. Operating Instructions
- Power On: Press the power button (⏻) to turn on the inflator. The digital display will illuminate.
- Set Pressure Unit: Press the 'R' button to cycle through available pressure units: PSI, BAR, KPA, or KG/CM². Select your desired unit.
- Set Target Pressure: Use the '+' and '-' buttons to adjust the target pressure to the recommended level for your tire or inflatable. Refer to your vehicle's owner's manual or the sticker on the driver's side door jamb for recommended tire pressures.
- Start Inflation: Once the target pressure is set, press the power button again to start the inflation process. The inflator will begin to pump air, and the digital display will show the current pressure.
- Auto Shut-Off: The inflator will automatically stop once the preset target pressure is reached, preventing over-inflation.
- Using the LED Light: Press the light button (💡) to turn on the integrated LED light for illumination in low-light conditions or emergencies. Press again to turn off.
- Disconnect: After inflation is complete and the inflator has shut off, disconnect the air hose from the valve stem and then unplug the 12V power cable from your vehicle.
