Page 8: Proper Use
In general, LUKAS hand combination tools can be used to cut, pull, spread, squeeze and lift objects. LUKAS hand combination tools can also be used under water at a depth of up to 40 m (131 ft). ATTENTION! In this case, you must pay strict attention to any leaks in order to prevent risks threatening the environment. -
Page 9: Functional Description
LUKAS hand combination tools are also fitted with a 360° rotating head so that optimal positioning of the blade arms and optimal pumping are always ensured. -

6. Cutting, spreading, pulling and squeezing 6.1 Safety notes Before the rescue work can commence, the position of the object involved in the accident must be stabilized. You must ensure an adequate substructure and/or adequate support for the object. Worldwide safety guidelines pertaining to the specific country must be observed and complied with. -
Page 12: Cutting
6.2 Cutting The blades must be positioned at a 90° angle to the object to be cut. 90° WRONG RIGHT Higher cutting capacities can be achieved by cutting as close as possible to the blade’s pivot point. WRONG RIGHT When cutting, the blade tips must not be offset (in the crosswise direction) by more than 3 mm (0.12 in.) as otherwise the blade is in danger of breaking. ATTENTION! Avoid cutting particularly high-strength parts of the vehicle’s bodywork (e.g. -

Dismantling the device/deactivation after operation Once the work has been completed, close the blade arms so that the distance to the tip is just a few mm. This relieves hydraulic and mechanical strain on the device. NOTE: Never store the combination tools with fully-closed blade arms! Complete closure of the blade arms can cause hydraulic and mechanical stress to build up... -
