Disconnecting the Hose from the Wrench
The co-axial coupling has a safety feature to prevent accidental disconnection during use. Learn how to disconnect the hose before using the equipment.
Support the swivel manifold at the opposite side to the coupling.
Push the hose towards the wrench (illustration 1) until the gap between the knurled collar and the nipple closes, as shown in (illustration 2).
While holding the above position, pull the knurled collar away from the wrench (illustration 3).
Pull the hose away from the wrench 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.
