Proper use3.
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 chainset. LUKAS handheld combi tools can basically be used to
cut, pull, open, squeeze and lift objects.
All objects which are to be worked on are to be secured using stable supports or
substructures.
LUKAS handheld combi tools are also suitable for use underwater down to a depth 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 / CAUTION!
The following may not be cut / squeezed:
- live cables
- pretensioned and hardened parts such as springs, spring steels,
steering columns and rollers
- tubes / hoses under gas or liquid pressure,
- compound materials (steel/concrete)
- explosive bodies such as airbag cartouches
NEVER operate the rescue equipment at a higher operating pressure than that
stated in the chapter “Technical data”. A higher setting can result in material
damage and/or injuries.
Spare parts and accessories for the rescue tool can be ordered from your authorised LUKASdealer!
