6. Connecting the hoses / devices
ATTENTION!
When connecting the hose lines, always ensure that the connection components
are not dirty. If necessary, clean before connecting!
WARNING / CAUTION / ATTENTION!
Before connecting the equipment, make sure that allthe
components used are suitable for the maximum operating
pressure of the hydraulic unit! In cases of doubt, you must
consult LUKAS directly before connecting the equipment!
NOTE:
Before connecting or disconnecting the hoses on the hydraulic power unit, make
sure that the power unit is switched off or, with a unit with an electric motor (PC
650) that it is isolated from the mains (pull the plug out)! This represents an
increased safety measure in order completely to prevent any movement of the
equipment.
The equipment is connected to the hydraulic pump via quick-disconnect coupling halves
(male and female).
Before coupling, remove dust caps and then pull back and hold the locking sleeve of the
female coupling half (position X). Connect the male and female couplings and release the
locking sleeve. Then turn the locking sleeve to position Y. The connection has been made
and locked. Uncoupling is done in the reverse order.
WARNING / CAUTION / ATTENTION!
Some quick-disconnect couplings have special functions.Therefore, you must
not unscrew them from the hoses or swap them over!

For dirt protection, the supplied dust protection caps must be refi tted.
NOTE:
Coupling is only possible if the hoses are depressurised.
Coupling the Quick-disconnect couplings
ATTENTION!
Always couple the return line (tank line - marked T on the pump block) fi rst
and then the supply line (pressure line - marked P on the pump block)!
On disconnecting, you should always disconnect
the supply line fi rst (pressure
line) and only then the return line!
