4. Operating Instructions
4.1 Inflation
- Connect the air hose to the INFLATE port on the pump and attach the correct nozzle to your inflatable.
- Turn on the pump. The digital display will activate.
- Select the desired pressure unit (PSI or BAR) and adjust the target pressure using the '+' and '-' buttons.
- Press the Start/Stop button to begin inflation. The pump will automatically switch from high-volume (350L/min) to high-pressure (70L/min) stage as needed.
- The pump will automatically stop once the preset pressure is reached.
4.2 Deflation
- Connect the air hose to the DEFLATE port on the pump and attach the correct nozzle to your inflatable.
- Press the Start/Stop button to begin deflation. The pump will actively extract air, allowing for compact packing.
- The pump will stop automatically after the preset deflation time (if applicable) or when manually stopped.

4.3 Smart Modes
The pump features three smart modes for optimized inflation:
- SUP Mode: Ideal for stand-up paddle boards and other high-pressure inflatables.
- KITE Mode: Suitable for surfing kites.
- MAT Mode: For air beds, inflatable sofas, swimming pools, and other low-pressure items. The centrifugal pump system can be used independently in MAT Mode.

4.4 Digital Display and Controls
The digital display shows the preset and real-time pressure. Buttons allow for power on/off, unit switching, and pressure adjustment. The pump automatically stops when the target pressure is reached.

5. Charging
The FLEXTAILGEAR EVO SUP Pump can be powered and charged via two methods:
- 12V DC Power Supply: Use the included 9.8ft 12V DC plug to connect to a car or outdoor power supply with a 12V interface. This allows for direct operation and charging.
- USB-C Charging: The pump can be recharged using a USB-C cable.
Note: This version of the pump is not rechargeable via its internal battery. The 12V DC power supply is for direct use.

Figure 7: The pump features both Type-C and 12V DC input ports for power and charging.
6. Maintenance
- Keep the pump away from water and sand to prevent damage.
- Do not allow water or foreign matter to enter the inflation or deflation ports.
- Regularly check nozzles and hose for any blockages or damage.
- Store the pump and accessories in the provided storage bag in a cool, dry place.

Figure 8: The pump is designed with heat dissipation features to maintain performance.
7. Troubleshooting
- Pump not turning on: Ensure the pump is properly connected to a 12V DC power source or that the internal battery (if applicable to your model) is charged.
- Slow inflation/deflation: Check for blockages in the hose or nozzles. Ensure the nozzle is securely attached to prevent air leaks. Verify the correct mode is selected for the inflatable.
- Inaccurate pressure reading: Ensure the nozzle is fully inserted and sealed into the inflatable's valve.
- Pump overheating: The pump has internal heat dissipation. If it feels excessively hot, allow it to cool down before continued use.
