Product safety2.
LUKAS products are developed and produced in order to ensure the best performance and
quality with proper use.
The safety of the operator is the most important consideration in the product design.
In addition, the operating instructions are to help in using the LUKAS products safely.
In addition to the operating instructions, all generally applicable, statutory and other
binding rules for accident prevention and for environmental protection must be heeded and
disseminated.
The device must only be operated by educated persons who are trained in safety technology,
since otherwise there is a risk of injury.
We advise all users before using the device to carefully read through the operating instructions
and to follow the instructions contained therein without exception.
5
We also recommend that you get instructed by a qualied trainer in the use of the product.
WARNING / CAUTION!
The operating instructions for the hoses, the accessories and the connected
devices must also be heeded!
Even if you have already received instruction, you should read the following safety instructions
again.
Make sure that no body parts
or clothing get between the
openly visible moving parts of
the device.
Wear protective clothing,
protective helm with visor,
safety shoes and protective
gloves.
Working under loads is
prohibited if they are raised
exclusively with hydraulic
devices. If this work is
unavoidable, sufcient
mechanical supports are
additionally required.
In the event of malfunctions,
shut down the device
immediately and secure it. You
should have the malfunction
repaired immediately.
Heed all safety instructions
and hazard warnings on the
device and in the operating
instructions.
Immediately report changes
that occur (including changes
in operating behaviour) to
the appropriate persons/
departments! If necessary,
immediately shut down and
secure the device!
Check the device for visible
defects or damage before and
after use.
Check all lines, hoses and
screwed connections for leaks
and externally visible damages
and repair immediately!
Escaping hydraulic uid can
lead to injuries and res.
Do not make any changes
(add-ons or conversions) on the
device without the approval of
LUKAS.
All safety instructions and
hazard warnings on the device
are to be kept intact and in a
legible condition.
Make sure that all safety covers
are present on the device and
in proper working condition.
Safety equipment must never
be disabled!
Any work procedure that
detracts from the safety and/or
stability of the device should be
abandoned!
The maximum permissible
operating pressure must not be
changed.
6
Before switching on/engaging
the device or while operating
the device, it must be ensured
that no one is endangered by
the operation of the device.
When working in the vicinity
of live components and lines,
take appropriate measures for
preventing current transfers or
high voltage ashovers to the
device.
Prevent electrostatic discharge,
which has the possible
consequence of spark
formation, when handling the
device.
The device is lled with
hydraulic uid. These hydraulic
uids can be detrimental to
health if they are swallowed
or their vapours are inhaled.
Direct contact with the skin
should be avoided for the same
reason. Also, when handling
hydraulic uids, note that they
can negatively affect biological
systems.
Make sure there is adequate
lighting while working.
Always keep these operating
instructions easily accessible
at the site where the device is
used.
Observe all intervals that
are prescribed or specied
in the operating instructions
for recurring tests and/or
inspections.
For repairs only original LUKAS
accessories and spare parts are
to be used.
Make sure that you do not
get caught in the hose loops
and trip when working with or
transporting the device.
When the hand pumps are set
up, care needs to be taken
that they are not impaired by
extremely strong temperature
changes.
When operating and/or storing
the device, make sure that the
function and the safety of the
device are not impaired by
strong external temperature
differences or that the device is
damaged. Keep in mind that the
device can also heat up when it
is continuously used.
Before transporting the device,
always check to see that the
accessories are positioned
securely to prevent the
possibility of an accident.
Make sure you properly dispose
of all removed parts, leftover
hydraulic uid, leftover oil and
packing materials.
In addition to the safety instructions of these operating instructions, all generally applicable,
statutory and otherwise binding national and international rules for accident prevention need
to be heeded and disseminated!

WARNING / CAUTION / ATTENTION!
The device is specied exclusively for the purpose represented in the operating
instructions (see Chapter "Proper use"). Any use that differs or goes beyond this is
considered improper. The manufacturer/supplier shall not be held liable for damages
resulting from improper use. The risk shall be borne solely by the user.
Proper use also includes heeding the operating instructions and complying with the inspection
and maintenance requirements.
Never work in a fatigued or intoxicated state!
Proper use3.
The LUKAS hand pump is used for the operation of LUKAS rescue devices.
They can be used as an additional or replacement drive source along with the LUKAS
hydraulic unit (e.g. in areas at risk for explosion).
Use with equipment of other manufacturers is possible, but requires technical testing and
approval of LUKAS on a case-by-case basis.
WARNING / CAUTION / ATTENTION!
Always note the product limitations with respect to operating pressure, load limit
values and operating conditions. The operating pressure should not be higher
than the lowest maximum operating pressure of any system components.
The operating pressure should NEVER be set higher than that which is specied
in the "Technical Data" chapter. A higher setting may cause property damage
and/or injuries.
Make sure that the usable capacity of the hand pump (see chapter "Technical
Data") is sufcient for operating the connected cylinders or devices.
The required hydraulic uid operating quantity can be found in the chapter
"Technical Data" or in the operating instructions of the devices to be operated.
Accessories and spare parts for the rescue equipment can be obtained from your authorised
LUKAS dealer!

Functional description5.
5.1 Base pump
All LUKAS hand pumps of this series are two-speed, i.e. they have two operating speeds:
• A high speed in the low pressure range (LP) for fast extension of the cylinder or device
while unloaded
• A low speed in the high pressure range (HP) for controlled extension of the cylinder or
device while loaded
The switch from low pressure (LP) to high pressure (HP) is automatic at the factory setting
for changeover pressure (see chapter "Technical Data").
A pressure port "P" with a G1/4" thread and a return port "T" with an M10 thread are directly
available as ports on the pump.
To connect rescue equipment, adapter blocks must be installed (see subchapter "Adapter
blocks" for more information). In the case of the hand pumps sold by LUKAS, one of these
adapter blocks is always included as standard equipment and is already installed.
Of course, the installed adapter blocks may be replaced with other ones. However, you must
contact an authorised LUKAS dealer or contact LUKAS directly.
The retractable handle of the LUKAS hand pump combines low required pumping force with
compact dimensions for storage and transport.
In addition, the LUKAS hand pumps for rescue equipment are equipped with a base plate to
ensure a more stable position during operation.

ATTENTION!
Make sure to store all plugs, screw plugs and/or dust caps in a way that
prevents them from getting dirty or lost.
After completion of the work, seal off all lines using screw plugs and/or dust
caps to prevent contamination of the hand pump.
When connecting lines to the hand pump, we recommend positioning it
vertically so that the ports point upward. This reduces the danger of hydraulic
uid escaping.
6.1 Fittings
The hose lines are connected via ttings to the hydraulic pump.
1. First remove the closure caps from
the ttings.

2. Then, you can connect the hose lines
2.
to the ttings and tighten them with a
tightening torque of M
= 40 Nm.
A
ATTENTION!
The return hose must always be connected at the "T" port of the
connection block.
The supply hose line must instead be connected at the "P" port.
