Flat face quick-release couplings allow the operator to remove and install work tools swiftly and efficiently. Generally, your
machine pipe work will have male and female couplings. The optional work tool hoses will have corresponding female and
The quick-release couplings should be trouble free and relatively easy to connect and disconnect, provided they are kept clean
and used correctly. The instructions listed below should always apply when using flat face quick-release couplings.
Follow the correct fitting and releasing procedures before installing or removing any optional work tool fitted with quick-
Quick-Release Couplings Do's & Don'ts
DO wipe the two faces of the coupling and ensure they are clean before connecting.
DO ensure the outside sleeve (female coupling) is pulled back when disconnecting.
DO connect and disconnect a new coupling two or three times to "work" the seals sometimes a new coupling will stick if the
seals have not been "worked."
DO use a spanner on the hexagonal flats of the coupling when fitting adaptors.
DO use a rubber or hide hammer to disconnect a coupling if it sticks sticking may occur if there is dirt present in the cou-
DON'T attempt to reconnect a damaged half coupling this will destroy the seals and necessitate replacing both half cou-
DON'T leave the coupling where it may be run over by a machine or otherwise crushed this will distort the coupling sleeve
and prevent correct connection and disconnection.
DON'T clamp on the smooth diameter of the coupling when fitting adaptors always use the hexagon.
DON'T damage the faces of the couplings this can prevent connection and disconnection, or damage seals and cause leak-
DON'T try to dismantle the couplings they are non-serviceable parts. If a coupling is damaged it should be replaced with a
Hydraulic fluid at pressure can injure you. Before attempting to connect or disconnect attachment
couplings remove any residual hydraulic pressure trapped in the service lines by fully operating all
the control levers pertaining to the circuit to be connected. Failure to follow this warning may result
in injury to personnel.
