3. Intended use
LUKAS handheld combi tools are specially designed for the rescue of casualties in road
accidents, rail accidents and in air travel, and for rescue from buildings. They serve the
purpose of freeing injured people in accidents e. g. by cutting doors, roof bars and hinges.
Trapped persons can also be freed using them e. g. by forcing open doors and/or by removing
obstacles with the aid of a chain set. LUKAS handheld combi tools can basically be used to
cut, pull, open, squeeze and lift objects.
LUKAS handheld combi tools are also suitable for use underwater to depths of 40 m (131ft) .
CAUTION!
In this case, you must strictly observe any leaks in order to avoid threats to the
environment.
WARNING / CAUTION!
All objects which are to be worked on are to be secured using stable supports or
substructures.
WARNING / ATTENTION / CAUTION!
The following may not be cut / squeezed:
- live electric cables
- pre-tensioned or hardened components, such as springs, spring steels, steering columns and rollers
- pressurised piping containing gases or liquids,
- composite materials (steel/concrete)
- explosive objects, such as airbag cartridges
NEVER operate the rescue equipment at a higher operating pressure than that
stated in the chapter entitled ‘Technical Data’. A higher setting can result in
material damage and/or injuries.
You can obtain accessories and spare parts for the rescue device from your authorised
LUKAS dealer!

4. Description of function
4.1 Description
The LUKAS handheld combi tools are a combi tool and handpump rolled into one unit.
Hydraulic power packs and energy supply or accumulators are therefore not required to
generate the required hydraulic pressure.
This is generated by moving the attached handle, in exactly the same manner as a hand
pump.
The working section of the tool is confi gured so that two equal opposing blade arms with
mechanical joints open or close symmetrically in order to open, squeeze, pull or cut objects.
In addition, LUKAS handheld combi tools are fi tted with a tool head that can rotate through
360° to allow optimum application of the blade arms at all times and ensure optimum
pumping.
4.2 Operational control
The working direction is adjusted before actuating the hand lever by turning the rotary knob
to the desired switching end point (see Cover Sheet Item 1).
The hand lever is actuated to move the two blade arms in the specifi ed working direction.
9
5. Operation
5.1 Controlling the working direction
The working direction is adjusted before actuating the hand lever by turning the rotary knob
to the desired switching end point.
Counterclockwise= closing blade arms - Cutting
Clockwise = opening blade arms - Spreading
5.2 Blade arm movement
Actuate the hand lever (up and down movement) to move the two blade arms in the set
working direction.
NOTE:
We recommend using full strokes when pumping. This means moving the hand
lever the full distance from one end stop to the other.
WARNING / CAUTION!
The hand lever can spring back when operating. This can be caused by excess
hydraulic pressure within the equipment or by external loading.
When operating the equipment, therefore, position yourself in such a way that you
will not be injured if the lever springs back.
10
6. Cutting, spreading, pulling and squeezing
6.1 Safety information
Before rescue works can commence, the position of the obstacle must be stabilised.
You must ensure an adequate substructure and / or adequate support of the object.
World-wide, safety guidelines pertaining to the specifi c country are to be observed and
complied with. In the Federal Republic of Germany , safety testing is carried out on a regular
basis, in accordance with GUV (German Legal Accident Insurance) regulations.
The following are to be worn when working with the rescue equipment:
- protective clothing,
- helmet with visor or goggles,
- safety gloves
- and ear defenders
Before activating the rescue equipment, always ensure that there is no danger to persons
either involved / uninvolved in the action by the movement of the rescue equipment or by
fl ying fragments. Further avoid unnecessary damage to property belonging to others, objects
not involved by the rescue equipment / fl ying fragments.
Reaching between the blade arms is strictly forbidden!
WARNING / CAUTION!
The particular effect of the force of the rescue equipment during operation could
cause pieces of the vehicle to break off or fl y off, posing a danger to persons.
Ensure that any persons not participating in the rescue are kept at an appropriate
distance from the equipment.
11
6.2 Cutting
The blades must be positioned at a 90° angle to the object to be cut.

Higher cutting capacities can be achieved by cutting as close as possible to the blade’s pivot
point.
RIGHT
During cutting, the gap between the blade tips (in the transverse direction) must not be
exceed of 3 mm (0.12 in.), otherwise the blade is in danger of breaking.
CAUTION!
Avoid cutting particularly high-strength parts of the vehicle’s bodywork (e.g.
side-impact protection): this almost always damages the combi tool!

6.3 Spreading
Use the front area of the tips for increasing the gap only. Full spreading capacity can be
achieved when approximately half of the grooved area of the tips is used. The greatest force
is created in the rear area of the spreading range of the combi blade.
Working surface is too small,
tips slip off.
Only for increasing the size
of a gap (not suitable for
spreading)
Tips get a safe grip.
6.4 Pulling
You may only use LUKAS chain sets for pulling purposes.
Before the pulling process can be performed, ensure that the bolt and hook fi t correctly to
prevent the chain from slipping.
Only chain sets in perfect condition may be used!
The pull chains are to be inspected at least once per year by an expert!
See separate operating instructions for the relevant LUKAS chain set in order to
correctly attach, affi x and use the chain sets.
A
Use load bolts to fasten the LUKAS
chainset connecting pieces to the blades
(drilled holes ‘A’). (see diagram right)
recommended chainset: KSV 8/50
13
6.5 Squeezing
Basically, squeezing may only be carried out in the area of the tips (see fi gure below).
Squeezing area
7. Dismantling the equipment / deactivation after use
Once work has been completed, the blade arms are to be closed so that there is a tip
distance of just a few mm. This relieves the hydraulic and mechanical strain on the device.
NOTE:
Never store the combi tool with the blade arms fully closed! The complete
closure of the blade arms can cause hydraulic and mechanical stress to build
up again.
Free the rescue equipment of any stubborn dirt which may have become attached during
use.
If the equipment is to be stored for a longer period of time, the exterior is to be cleaned
completely and the mechanically mobile parts are to be lubricated.
Avoid storing the rescue equipment in a damp environment.
8. Care and maintenance
The equipment are subject to very high mechanical stresses. A visual inspection is to be
carried out after every use: however, at least one visual inspection is to be carried out every
six months. These inspections enable the early detection of wear and tear, which means
that punctual replacement of this wearing parts prevents breakages from occurring. Also
regularly check the torque of the pivot bolt. (For tightening torques M
Fracture testing of the blades must be carried out after 3 years. Therefore a special crack
testing kit is available.
Every three years or if there is any doubt regarding the safety or reliability of the equipment,
a function test must also be performed. (Please also observe the relevant valid national and
international regulations pertaining to service intervals of rescue equipment). In the Federal
Republic of Germany, safety testing is carried out on a regular basis, in accordance with
GUV (German Legal Accident Insurance) regulations.
