# Disconnecting the Hose from the Pump

The co-axial coupling has a safety feature to prevent accidental disconnection during use. Learn how to disconnect the hose before using the equipment.

1. Hold the pump frame to prevent the pump from moving during the disconnection.

2. Push the hose nipple towards the pump (illustration 1) until the gap between the knurled collar and the nipple closes (illustration 2).

3. While holding the above position, push the knurled collar towards the pump (Illustration 3).

4. Pull the hose away from the pump and the connection will automatically spring apart (illustration 4).

If the connections are not pushed together and held, the knurled collar cannot move, therefore the couplings cannot be disconnected. This is a safety feature to prevent accidental disconnection.
