5. Operating Instructions

5.1 General Inflation Procedure

1. Prepare the Inflator: Ensure the unit is charged. Attach the air hose to the inflator's air outlet by twisting it clockwise until secure.
2. Select the Correct Nozzle/Adapter:
   • For Car/Motorcycle Tires: Use the Schrader valve mouthpiece.
   • For Bicycle Tires with Presta Valves: Screw the French adapter onto the valve stem first, then attach the Schrader mouthpiece.
   • For Sports Balls: Use the ball needle. Moisten the needle slightly before insertion.
   • For General Inflatables: Use the atmospheric nozzle.
3. Connect to the Valve: Firmly press the appropriate nozzle onto the valve stem. For tire valves, you may need to press down to unlock the valve core and ensure a tight seal to prevent air leakage.
4. Power On: Press the Power button. The digital screens will illuminate.
5. Set Parameters:
   • Press the UNIT button to select your preferred pressure unit (e.g., PSI).
   • Press the MODE (M) button to select a preset mode (Car, Motorcycle, Bicycle, Ball) or Manual mode.
     • In a Preset Mode, the target pressure is automatically set to a common value for that item.
     • In Manual Mode, use the + and - buttons to set your desired target pressure. Refer to your vehicle's door jamb sticker or equipment manual for correct pressure.
6. Start Inflation: Once the target pressure (on the left screen) is set, the inflator will automatically begin pumping. The right screen shows the real-time pressure increasing.
7. Automatic Shut-Off: The inflator will automatically stop when the real-time pressure reaches the preset target pressure.
8. Disconnect: After the unit stops, quickly remove the nozzle from the valve to prevent air from escaping back into the hose. Press the Power button to turn the unit off.
9. Check Pressure: Use a separate tire gauge to verify pressure if desired. The inflator's gauge is accurate, but a secondary check is good practice.

5.2 Using the LED Flashlight

Press and hold the Power button for 2 seconds to turn the LED light on or off. The light operates independently of the inflation function.

5.3 Using the USB Output Port

You can use the inflator as a power bank. Use your own USB cable to connect a device (e.g., phone) to the inflator's USB output port. The inflator must have battery charge remaining.

6. Safety Instructions and Warnings

• Intended Use: This inflator is designed for inflating tires and inflatable objects. Do not use it for breathing air, aerosol products, or any other purpose.
• Heat and Ventilation: The motor may become hot during extended use. Allow the unit to cool down between continuous inflation cycles. Operate in a well-ventilated area.
• Pressure Limits: Do not exceed the maximum pressure rating of 150 PSI or the maximum pressure rating of the item you are inflating. Over-inflation can cause tire or object failure, leading to explosion and serious injury.
• Battery Safety:
  • Use only the provided USB cable or a certified equivalent for charging.
  • Do not expose the unit to extreme heat, fire, or direct sunlight for prolonged periods.
  • Do not attempt to disassemble the unit or replace the battery.
  • If the battery is damaged, discontinue use immediately.
• Children: This is not a toy. Keep out of reach of children.
• Storage: Store in the provided bag in a cool, dry place away from sharp objects.
• Inspection: Regularly inspect the air hose and nozzles for cracks, wear, or damage before use. Do not use if any part is damaged.
