Before coupling, remove dust protection caps, then connect male and female, and turn
the locking sleeve of the female in direction “1” until the locking sleeve locks into place.
The connection is then made and secured. Decoupling is accomplished by turning the
locking sleeve in direction “0”.
The equipment can also be coupled under pressure provided the connected equipment is
not activated.
NOTE:
We recommend coupling the coupling halves in a depressurised state when
working in areas with low ambient temperature and extension hose assemblies /
hose reels are used, otherwise coupling could need very high expenditure of
force.
For dust protection, the supplied dust caps must be reattached.
WARNING / CAUTION!
The mono-couplings may not be screwed off the hose assemblies and / or the
hose assemblies be mixed up!
Using the dust protection caps:
The “A” dust protection caps have two internal pins “B”. The dust protection caps must be
placed on the coupling unions in such a way that the pins are guided into the “C” grooves.
Fasten the screw up to the limit stop to fix the dust protection caps on the coupling unions.
