2. Safety Information
Always follow basic safety precautions when using electrical appliances to reduce the risk of fire, electric shock, and personal injury.

4. Product Overview and Features
The FOWAWU SUP Air Pump is designed for ease of use and efficiency. Key features include:
- Dual-Stage Inflation: The pump operates in two stages for rapid inflation. The first stage provides high volume (400L/min) for quick filling, while the second stage provides high pressure (100L/min) to reach the desired PSI.
- Intelligent Auto-Off: Set your desired pressure (up to 20 PSI), and the pump will automatically shut off once the target pressure is reached, preventing over-inflation.
- Inflation & Deflation Function: Equipped with separate ports for inflation and deflation, allowing for quick packing up of inflatable items.
- 12V DC Car Connector: Powered directly from your car's 12V DC outlet, making it ideal for on-the-go use.
- 6 Universal Air Nozzles: Comes with a variety of nozzles to fit most inflatable products, including SUPs, kayaks, air beds, and yoga balls.
- Active Cooling System: Features an internal cooling fan and cleverly designed air ducts to dissipate heat, allowing for continuous operation and extended pump life.
- Integrated LED Flashlight: A built-in LED light provides illumination for use in low-light conditions or at night.
- Portable Design: Ergonomic large handle and included storage bag for easy transport and storage.

5. Setup
Before operating your FOWAWU SUP Air Pump, follow these setup steps:
- Connect the Hose: Attach one end of the flexible hose to the appropriate port on the pump. For inflation, connect to the port labeled "Inflate". For deflation, connect to the port labeled "Deflate". Ensure a secure connection.
- Select the Nozzle: Choose the correct air nozzle that fits the valve of your inflatable item. The pump comes with 6 different interfaces. Securely attach the selected nozzle to the other end of the hose.
- Connect to Power: Plug the 12V DC car connector into your vehicle's cigarette lighter socket. Ensure your vehicle's engine is running to provide stable power.

6. Operating Instructions
6.1. Inflation
- Ensure the hose is connected to the "Inflate" port and the correct nozzle is attached to your inflatable item's valve.
- Plug the 12V DC car connector into your vehicle's power outlet.
- Press the power button to turn on the pump. The digital display will light up.
- Use the PSI/BAR/KPA button to select your desired pressure unit.
- Use the '+' and '-' buttons to set the target pressure. The maximum pressure is 20 PSI.
- Press the start button (usually a play/pause icon) to begin inflation. The pump will start in the high-volume stage and then switch to the high-pressure stage automatically.
- The pump will automatically stop once the preset pressure is reached.
- Disconnect the nozzle from the inflatable item and then unplug the pump from the power source.

6.2. Deflation
- Connect the hose to the "Deflate" port on the pump.
- Attach the appropriate nozzle to the valve of the inflatable item.
- Plug the 12V DC car connector into your vehicle's power outlet.
- Press the power button to turn on the pump.
- Press the start button to begin deflation. The pump will actively suck air out of the item.
- Once deflation is complete, turn off the pump and disconnect it.
6.3. Using the LED Flashlight
The integrated LED flashlight can be activated independently of the pump's inflation/deflation function. Locate the dedicated button for the flashlight (refer to the product diagram if unsure) and press it to turn the light on or off.
7. Maintenance
Proper maintenance ensures the longevity and optimal performance of your FOWAWU SUP Air Pump.
- Cleaning: Wipe the exterior of the pump with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the air inlet and outlet are free from dust and debris.
- Storage: After each use, ensure the pump is clean and dry. Store it in the provided storage bag in a cool, dry place, away from direct sunlight and extreme temperatures.
- Hose and Nozzles: Keep the hose and nozzles clean and free from kinks or damage. Store them neatly to prevent wear and tear.
- Fuse Replacement: If the pump stops working, check the fuse in the 12V DC car connector. Replace it with the provided backup fuse if necessary. Refer to the diagram on the connector for fuse access.
8. Troubleshooting
If you encounter issues with your FOWAWU SUP Air Pump, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | No power from car outlet; Blown fuse in car connector; Loose connection. | Ensure car engine is running. Check car's cigarette lighter fuse. Check pump's fuse in the 12V connector and replace if blown. Ensure all connections are secure. |
| Pump inflates slowly or not to desired pressure. | Incorrect nozzle; Air leakage; Blocked air inlet/outlet; Item is too large for pump capacity. | Ensure correct nozzle is used and securely attached. Check for leaks in the hose or inflatable item. Clear any obstructions from air inlet/outlet. For very large items, inflation time will be longer. |
| Pump overheats and shuts off. | Continuous operation for too long; Blocked cooling vents. | Allow the pump to cool down for 15-20 minutes before resuming operation. Ensure cooling vents are not blocked. |
| Pump does not auto-stop. | Pressure setting too high or too low; Faulty pressure sensor. | Verify the preset pressure is appropriate for the item. If the issue persists, contact customer support. |
