CAUTION!
When connecting the hose assemblies, always ensure that the connection
components are not soiled; clean beforehand if necessary.
WARNING / DANGER / CAUTION!
Before connecting equipment, make sure that all the 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.
Connection of the hoses 6.
REMARK:
Before you attempt to connect or disconnect hose lines to or from the hydraulic
unit, including hose lines with quick-disconnect couplings, always make sure
that the pump assembly is switched off. Electric pumps must be disconnected
from the power supply.
The equipment is connected to the hydraulic pump via quick-disconnect coupling halves (male
and female).
Before coupling, remove the dust protection caps, then pull back and hold the locking sleeve
of the female coupling (position X). Fit the socket and plug together and release the locking
sleeve. Then turn the locking sleeve to position Y. The connection has now been made and
locked. Disconnection is made in the reverse order.
WARNING / DANGER / CAUTION!
Some quick-disconnect couplings have special functions. Therefore it is not
permitted to screw them off the hoses or to swap them.

To protect against dust, the accompanying dust protection caps must be replaced.
REMARK:
Coupling of the devices is only possible when the hoses are depressurised.

CAUTION!
Always couple the return hose first and then the supply hose.
On disconnecting, you should always disconnect the supply line first and then
the return pipe.
