On the double-acting hydraulically-actuated working equipment, there is, on the
pressure supply side (with cylinders: the cylinder base side) a quick-disconnect nipple,
and, on the return side (piston rod side) a quick-disconnect sleeve; and these are connected
to the control table using a pair of extension hoses. On the hose ends we connect, in each
case, a nipple on the sleeve on the end equipment and a sleeve on the nipple on the end
equipment to prevent mix-ups.
You can also place coloured clip rings (supplied with the equipment) on the kink-preventer to
make it visually easier to make connections to several end equipment items.
A quick-disconnect nipple is provided on the single-acting hydraulically-actuated working
equipment to provide a pressure supply. they are connected to the control table via
an extension hose. If you are using earlier versions of single-acting cylinders, LUKAS
recommends that you contact LUKAS or an authorised dealer.
The connection between the control table and the hydraulic power pack is either via
the fi xed short connection hoses, in order to place the power pack under the control
table, or via hose extensions in order to allow the power pack to remain on the vehicle,
for example, and only the control table needs then to be transported to the site of
deployment. The hose extension pairs are supplied in various lengths. The individual hoses
can, if required, also be marked with coloured snap rings to make it easier to allocate the
hoses. (For specifi c details, please consult the LUKAS range of accessories or contact your
LUKAS dealer.)
WARNING / CAUTION / ATTENTION!
Prior to connecting the devices, ensure that all the components
being used are suitable for the maximum operating pressure
of the unit! In case of doubt you must consult LUKAS directly!
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. Coupling of the devices is only possible,
when the hoses are depressurized. For dust protection, the supplied dust caps must be
refi tted.
5.3 Coupling the quick-disconnect couplings
The device is connected to the hydraulic pump without risk of misconnection using
monocoupling halves (female and male coupling).

ATTENTION!
Always connect the return line fi rst and then the supply line!
