6. Operating Instructions
6.1. Inflating a Tire
- Check Recommended Pressure: Locate the recommended tire pressure for your vehicle (usually found on a sticker inside the driver's side door jamb, in the owner's manual, or on the tire sidewall).
- Connect Air Hose: Screw the air hose connector securely onto the tire valve stem. Ensure there are no air leaks. The digital display will show the current tire pressure.
- Set Target Pressure: Use the "+" and "-" buttons to set the desired target pressure. The display will flash the set value.
- Start Inflation: Once the target pressure is set, press the power button again to start the inflation process. The compressor will begin to pump air.
- Auto-Stop Function: The inflator will automatically stop once the preset pressure is reached. The display will show the final pressure.
- Disconnect: Unscrew the air hose connector from the tire valve stem. A small amount of air may escape, which is normal.
- Power Off: Press the power button to turn off the inflator and disconnect it from the 12V power source.
6.2. Using the LED Light
The integrated LED light can be activated independently to provide illumination during nighttime or low-light operations. Refer to the specific button on your device for LED light activation (often a dedicated button or a long press of the power button).
7. Maintenance
- Cleaning: Wipe the exterior of the inflator with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the inflator in a dry, cool place, away from direct sunlight and extreme temperatures. Ensure the power cord and air hose are neatly coiled to prevent damage.
- Check Connections: Periodically inspect the power cord and air hose for any signs of wear, cuts, or damage. Replace if necessary.
8. Troubleshooting
| Problem | Possible Cause | Solution |
