2. Product safety

LUKAS products are developed and manufactured in order to guarantee the best performance and quality when used properly. Operator safety is the most important aspect of the product design. Furthermore, the operating instructions are intended to help in using LUKAS products safely. The generally applicable, legal and other binding regulations pertaining to the prevention of accidents and protection of the environment apply and are to be implemented in addition to the operating instructions. The device may only be operated by persons with appropriate training in the safety aspects of such equipment – otherwise, there is a danger of injury occurring. We would like to point out to all users that they should read carefully the operating instructions and the instructions contained therein before they use the device, and that they should carefully follow such. We also recommend that you get instructed by a qualiﬁ ed trainer in the use of the product.

Wear protective clothing, safety helmet with visor, protective gloves

Immediately report any changes that occur (including changes in operating behaviour) to the appropriate persons/departments! If necessary, the device is to be deactivated immediately and secured!

It is prohibited to work under load if this load is lifted exclusively by hydraulic equipment. If this work is absolutely imperative, additional mechanical supports must be used.

Inspect the equipment before and after use for visible defects or damage

Check all screwed ﬁ ttings for leaks and externally detectable damage and rectify immediately! Squirting hydraulic ﬂ uid can result in injuries and ﬁ res.

In the event of malfunctions, immediately deactivate the equipment and secure it. The malfunction is to be repaired immediately .

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 (131 ft) .

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!
