REMARK:
We recommend coupling the coupling halves in a pressureless state, when
working in areas with low ambient temperature and the usage of extension hose
assemblies / hose reels, otherwise decoupling could need very high expenditure
of force.
To protect them from dust, the accompanying dust protection caps must be put back on.
WARNING/CAUTION!
The mono-couplings may not be screwed off the hose assemblies and / or the
hose assemblies be confused!
6.3 Coupling the quick-disconnect couplings (alternative system)
The equipment is connected to the hydraulic pump via quick-disconnect-coupling halves
(male and female).
Before coupling unlock the connect socket by turning the sleeve into position X. Retract
sleeve and connect plug and socket. Release sleeve and turn it into position Y.
Now the connection has been made and locked. Uncoupling is done in the reverse order.
WARNING/CAUTION!
The quick-disconnect-couplings partly have special functions. Therefore it is not
allowed to screw them off from the hoses or to exchange them!

To protect them from dust, the accompanying dust protection caps must be put back on.
REMARK:
Coupling of the devices is only possible, when the hoses are depressurized.
CAUTION!
Always connect the return line fi rst and afterwards the supply line!
