be replaced with a new one. See coupling guides for
a reference.
– Never hit the centre poppet of the coupling to try and
release locked in pressure. This can cause
irreparable damage to the coupling and serious injury.
– When fitting couplings, never clamp on the sleeve of
the female or nose of the male - this will cause
distortion and/or damage.
– Never subject the couplings to external forces,
especially side load. This can reduce the life of the
coupling or cause failure.
– Never allow the torsional forces transmitted from
hoses to unscrew/screw together couplings.
– Never use a coupling as a plug.
– Do not connect and disconnect with pressure in the
line unless the coupling type is specifically designed
to do so.
Connecting Quick Release Couplings
1 Remove any residual hydraulic pressure trapped in
the service line hose.
2 Wipe the two faces of the male and female couplings
and make sure they are clean.
3 Make sure that ball C in the female coupling is located
in one of its slots.
4 Fit the male coupling into the female coupling.
5 Where applicable, rotate sleeve E half a turn and
make sure that the locking ball C does not align with
the slot D.
Disconnecting Quick Release Couplings
1 Remove any residual hydraulic pressure trapped in
the service line hose.
2 Where applicable, align the slot D with ball C.
