2. Attaching Nozzles
Select the appropriate nozzle for your inflatable item. The pump includes four nozzle sizes:
- Nozzle S: Ideal for small inflatables like pool toys and swimming rings.
- Nozzle M: Suitable for medium inflatables such as pool floats and camping pads.
- Nozzle L: Designed for high-volume inflatables like large pools and air mattresses.
- Nozzle XL: Primarily for deflating vacuum storage bags and other inflatables (often used in conjunction with Nozzle L for deflation).
Firmly insert the chosen nozzle into the inflation or deflation port of the pump until it is securely seated.
