Setup
- Connect the Air Hose: Attach one end of the flexible air hose to the pump's inflation port. Twist clockwise until secure.
- Select and Attach Nozzle: Choose the appropriate nozzle attachment for your inflatable item (e.g., paddle board, kayak, air bed). Insert it firmly into the other end of the air hose. Ensure a tight seal. Using white gaskets can improve the seal.
- Connect to Power: Plug the 12V DC car connector into your vehicle's 12V accessory socket. Then, connect the other end of the power cable to the pump's power input port.

Operating Instructions
- Set Desired Pressure: With the pump powered on, the digital display will show the current pressure unit (PSI or BAR). Use the "+" and "-" buttons to adjust the target pressure. The pump supports up to 20 PSI.
- Start Inflation: Connect the nozzle securely to the valve of your inflatable item. Press the power button to start the inflation process. The pump will begin inflating, and the digital display will show the real-time pressure.
- Automatic Shut-off: The pump features an auto-off function. Once the set target pressure is reached, the pump will automatically stop, preventing over-inflation and potential damage to your inflatable.
- Monitor Progress: The digital display allows you to monitor the inflation progress in real-time.
- Continuous Operation: The pump is designed for continuous operation, capable of inflating multiple items consecutively. However, if the unit feels excessively hot, allow it to cool before further use.

Maintenance
- Cleaning: Wipe the pump exterior with a dry or slightly damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the pump and its accessories in the provided storage bag in a cool, dry place away from direct sunlight.
- Cooling: If the pump operates for an extended period or inflates multiple items, it may become warm. Allow it to cool down for at least 10-15 minutes before further use to prevent overheating.
- Nozzle Inspection: Regularly check the nozzle attachments and gaskets for wear or damage. Replace if necessary to ensure a proper seal.
