The equipment is filled with
hydraulic fluid. This hydraulic
fluid can be detrimental to
health if it is swallowed or
its vapour is inhaled. Direct
contact with the skin must
be avoided for the same
reason. Also, when handling
hydraulic fluid, note that it can
negatively affect biological
systems.
When working with or storing
the equipment, ensure that
the function and the safety
of the equipment are not
impaired by the effects of
severe external temperatures
or that the equipment is
damaged in any way. Please
note that the equipment can
also heat up over a long
period of use.
Make sure there is adequate
lighting while working.
Before transporting the
equipment, always ensure that
the accessories are positioned
in such a way that they cannot
cause an accident.
Always keep these operating
instructions easily accessible
at the place of operation.
Ensure the proper disposal of
all removed parts, left-over oil
and hydraulic fluid as well as
packaging materials!
Protect all of the lifting set
components against humidity
and moisture
The hand pump is not suitable
for underwater applications.
The build-up of static charge
and therefore possible
sparking must be avoided
when handling the device.
Always wear protective gloves
to prevent injury when touching
torn or sharp-edged parts.
The generally applicable, legal and other binding national and international regulations
pertaining to the prevention of accidents and protection of the environment apply and are to
be implemented in addition to the operating instructions.

3. Appropriate use
The LUKAS lifting sets are specially designed for the lifting or stabilising of heavy or movable
loads requiring lifting in order to free persons, vehicles or other objects from operations in
dangerous or catastrophic situations.
The lifting cylinders can also be used in all types of dangerous situations for the shifting or
lifting of objects to rescue buried or trapped persons or to recover any type of heavy object
(vehicles, devices, etc.).
Buildings in danger of collapsing or heavy vehicles in danger of crashing can be temporarily
secured and stabilised.
Thanks to the cylinder's low design, the lifting sets can be particularly well used for initial
lifting at low clearance heights between the object and the floor. The cylinder extensions can
additionally be used to increase the initial height of the stroke.
The cylinder unit of the lifting set is suitable for underwater applications. The hand pump
requires an air exchange through the tank cover of the hydraulic fluid container.
Additional safety instructions:
• Never use hydraulic cylinders without a base plate (stability). Use hard wood
spacers if possible to provide additional stability of the load.
• Never use more than one extension per cylinder (risk of buckling with multiple
arrangements).
• Always load the hydraulic cylinder in the centre (in the direction of the cylinder axis)!
Exception: Use of the foot lifter according to instructions.
• Work with a support bar when using the foot lifter (see Accessories section).
Screw the foot lifter on in reverse for loads with low internal strength and use it
without the support bar. Use suitable underlays or support bars to provide additional
support if necessary.
• Always lay the hoses to be free of twists and kinks!
• Pay extremely close attention to the moving load during the lifting and lowering
processes!
• Always provide additional mechanical support to raised loads!
• No bystanders are allowed in the hazard zone!
WARNING / CAUTION / ATTENTION!
The system is exclusively intended for the purpose stated in the operating instructions
(see section "Appropriate Use"). Any other use is not considered appropriate.
The manufacturer/supplier is not liable for any damage resulting from inappropriate use.
The user bears sole responsibility for such use.
Appropriate use includes observance of the operating instructions and compliance with the
inspection and maintenance conditions.
Never work in a fatigued or intoxicated state!

WARNING / CAUTION / ATTENTION!
The following may not be pressurised or squeezed:
- electric cables
- prestressed and hardened parts such as springs, spring steels,
steering columns and rollers
- tubes or containers under gas or liquid pressure
- explosive bodies such as airbag cartridges
The internally set operating pressure may only be directly changed after
consultation with LUKAS. A change in settings may result in damage to property
and/or injuries.
The H1and H2 lifting sets are not explosion protected!
When using the equipment in explosive areas you must rule out any chance of
the equipment causing an explosion.
The responsibility for explosion prevention or for prohibiting work with a lifting set
rests with the operator of the device or with the person responsible at the place
of use.
When working in explosive areas, all applicable legal, national
and international regulations, standards and safety rules for
avoiding explosions must be observed without restriction!
The lifting set should not come into contact with acids or alkalis. If this is
unavoidable, clean the equipment immediately afterwards with a suitable cleaning
agent.
You can obtain other accessories and replacement parts for the lifting sets from your
authorised LUKAS dealer!
WARNING / CAUTION!
Always ensure that the surroundings of the object to be lifted remain stable and
are secured against accidental shifting by sustainable supports or substructures.

4. System description and overview
4.1 Design of the system and connection of the components
2
1
A LUKAS lifting set generally includes a hydraulic hand pump which serves as a drive for
one or two single-acting hydraulic cylinders. Operating the hand pump presses hydraulic
fluid into the cylinder or cylinders, causing the cylinder piston to extend and lift an attached
load. The reset spring in the cylinder causes the cylinder to retract in the idle stroke or it is
retracted under loading by the force exerted by the attached load.
The components are joined together by connection hoses and couplings.
The accessories make it possible to optimally use the cylinders in any position desired at
the site.
The cylinders are controlled by the pump movement on the hand pump. The drain valve
must be closed to build up pressure. The hand wheels (distributor stop valves) must be open
when two cylinders are operated with 2-way distributors. A hydraulic load holding function
is provided when the isolating valves (distributors) are closed. You should also secure the
system mechanically when the cylinders are continuously loaded (under load).
