4. Setup and Assembly
- Charge the Device: Before first use, fully charge the air pump using the provided USB-C charging cable. Connect the cable to the pump's charging port and a compatible 5V/3A power adapter. The charging time is approximately 3.5 hours.
- Connect the Air Pipe: Screw the high-pressure air pipe extension onto the air pump's outlet. Ensure it is securely fastened to prevent air leakage.
- Select the Correct Nozzle: Choose the appropriate nozzle converter (e.g., French Air Nozzle Converter, Inflation Needle, Quick Connect Gas Nozzle Converter) for the item you intend to inflate. Attach it firmly to the end of the air pipe.
- Attach to Item: Connect the assembled air pipe and nozzle to the valve of the item you wish to inflate (e.g., car tire, bicycle tire, sports ball). Ensure a snug fit to prevent air escape.
5. Operating Instructions
- Power On: Press the power button to turn on the device. The digital display will light up, showing the current pressure.
- Select Mode: Use the mode selection button to cycle through the preset inflation modes: Custom, Bicycle, Motorcycle, Car, Scooter, and Ball. Each mode has a default pressure value.
- Adjust Pressure (Optional): If using Custom Mode or adjusting a preset, use the '+' and '-' buttons to set the desired pressure value. The pump detects pressure with ±1psi accuracy.
- Start Inflation: Press the inflation button to begin inflating. The pump will automatically stop once the preset pressure is reached.
- Emergency Lighting: The pump is equipped with white light illumination for daily vehicle maintenance and an SOS flashing mode for emergencies. Refer to the manual for specific button presses to activate these features.
- Power Off: Press and hold the power button to turn off the device when not in use.
6. Maintenance
- Charging: Recharge the device when the four-segment power display indicates low battery. Use only the provided USB-C cable and a compatible power adapter.
- Cleaning: Wipe the exterior of the pump with a soft, dry cloth. Do not use harsh chemicals or immerse the device in water.
- Storage: Store the air pump and its accessories in the provided storage bag in a cool, dry place, away from direct sunlight and extreme temperatures.
- Nozzle Care: Keep all nozzles and the air pipe clean and free from debris to ensure efficient inflation.
7. Troubleshooting
- Device does not turn on:
- Ensure the device is fully charged. If the battery is depleted, connect it to a power source using the USB-C cable and allow it to charge for at least 30 minutes before attempting to power on again.
- Inflation is slow or not working:
- Check if the air pipe and nozzle are securely connected to both the pump and the item being inflated. Ensure there are no leaks. Verify that the selected pressure is appropriate for the item. The internal 27mm high-precision alloy die-casting cylinder body is designed for quick pressurization, so check for obstructions if performance is low.
- Inaccurate pressure reading:
- Ensure the nozzle is properly sealed to the valve. The pump provides ±1psi accurate tire pressure detection. If discrepancies persist, recalibrate by turning the device off and on, or consult the full manual.
- Battery life seems short:
- Ensure the device is fully charged before use. Large-capacity lithium battery allows for significant use (e.g., 16 automobile tires, 30 bike tires, 138 basketballs on a full charge). If battery life significantly degrades, contact support.
