Precautions when connecting and disconnecting sockets and plugs
In order to prevent unexpected disconnection, whentensile force exists, the locking chuck gets caught inthe step of the inner diameter of the sleeve and does
not move even when pressurized.
When actuating the sleeve, remove the tensile force
applied to this product before doing so.

Sleeve is inoperable due to catch.
