5.3 Coupling the quick-disconnect couplings
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!

REMARK:
Coupling of the devices is only possible, when the hoses are depressurized.
