4.2 Attaching the Hose and Nozzle
Select the appropriate nozzle for your inflatable item.
- Identify the correct port on the pump:
- Inflation Port: Typically marked with an arrow pointing outwards or "INFLATE".
- Deflation Port: Typically marked with an arrow pointing inwards or "DEFLATE".
- Screw the flexible hose securely into the desired port (inflation or deflation).
- Attach the appropriate air nozzle to the other end of the flexible hose. Ensure it fits snugly to prevent air leakage.
5. Operating Instructions
5.1 Powering On/Off
- To power on: Press and hold the power button (↻) for a few seconds until the digital display illuminates.
- To power off: Press and hold the power button (↻) again until the display turns off.
5.2 Setting Target Pressure
The pump allows you to set a desired pressure (PSI) for automatic shut-off.
- With the pump powered on, use the '+' and '-' buttons to adjust the target pressure on the digital display.
- The display shows the current pressure in real-time.
- Refer to your inflatable item's recommended pressure for optimal performance and safety.
5.3 Inflation Process
The pump utilizes a dual-stage inflation system for efficiency.
- Ensure the hose is connected to the inflation port and the correct nozzle is attached to your inflatable.
- Set your desired target pressure using the '+' and '-' buttons.
- Press the start button (often indicated by a play/pause symbol or similar).
- The pump will begin in Stage 1 (high volume, low pressure) for rapid filling.
- Once a certain pressure is reached, it will automatically switch to Stage 2 (low volume, high pressure) to achieve the precise target PSI.
- The pump will automatically shut off once the preset pressure is reached.
