For dust protection, the supplied dust protection caps must be refitted.
WARNING / CAUTION / ATTENTION!
Some quick-disconnect couplings have special functions and may therefore not
be unscrewed from the hydraulic lines and/or swapped!
NOTE:
It is only possible to connect devices when the hoses are depressurised.
CAUTION!
Always connect the return hose first and then the supply hose!
Before coupling, remove the dust protection caps and then pull back and hold the locking
sleeve of the female coupling half (position X). Connect the male and female coupling together
and release the locking sleeve. Then turn the locking sleeve to position Y. The connection has
now been made and locked. Disconnection is carried out in the reverse order. Hoses can be
connected only when depressurised. For dust protection, the supplied dust protection caps
must be refitted.
6.2 Coupling quick-disconnect couplings
The equipment is connected to the hydraulic pump via quick-disconnect-coupling halves
(male and female).

6.1 Hydraulic
On the device side, a quick-disconnect coupling sleeve is provided on the piston rod side of
the valve, and a quick-disconnect coupling nipple on the cylinder base side of the valve; they
are connected to the pump unit via two extension hoses.
All LUKAS pairs of extension hoses are colour coded and are equipped with quick-disconnect
couplings so that they cannot be mixed up when being connected.
6. Connecting the equipment
WARNING / CAUTION / ATTENTION!
Prior to connecting the devices, ensure that all the components
being used are suitable for the maximum operating pressure
of the pump unit. In the case of doubt you must consult LUKAS
directly!
