        Unscrew the top cap of the nozzle.

        Tap the pump gently so that a flexible rubber tube and a hard plastic tube come out of the nozzle.

      • 4

        Flip the plastic piece upside-down so that the pointed end faces out of the nozzle. Then slide this piece back into the nozzle opening.

      • 5

        Flip the rubber piece so that the end with the larger donut hole faces up, and slide it into the nozzle on top of the plastic piece.
