1. Hazard classes We distinguish between various categories of safety instructions. The table below gives you an overview of the assignment of symbols (pictograms) and key words to the specific hazard and possible consequences.
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.
In the event of malfunctions, immediately deactivate the equipment and secure it. The malfunction is to be repaired immediately. Observe all safety and danger notes on the device and in the operating instructions.
The device is filled with a hydraulic fluid. These hydraulic fluids can be dangerous to health if swallowed or their vapours inhaled. Direct contact with the skin is to be avoided for the same reason. Please also note that hydraulic liquids can also have a negative effect on biological systems. When working with or storing the device, ensure that the function and the safety of the device are not impaired by the effects of stark external temperatures or that the device is damaged in any way.
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.
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.
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 - Spreading = opening blade arms 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.
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 specific 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.
6.2 Cutting The blades must be positioned at a 90° angle to the object to be cut. 15° 15° 12 90° 9 3 WRONG RIGHT 6 Higher cutting capacities can be achieved by cutting as close as possible to the blade’s pivot point. WRONG 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.
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. Tips get a safe grip. Working surface is too small, tips slip off. Only for increasing the size of a gap (not suitable for spreading) 6.4 Pulling You may only use LUKAS chain sets for pulling purposes.
6.5 Squeezing Basically, squeezing may only be carried out in the area of the tips (see figure 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.
CAUTION! Clean off any dirt before checking the device! When cleaning the equipment, ensure that no cleaning agents are used with pH values outside the range 5 - 8! WARNING / ATTENTION / CAUTION! In order to carry out maintenance and repair works, tools appropriate for the job and personal protecting equipment are essential.
9. Repairs 9.1 General Servicing may only be carried out by the manufacturer or personnel trained by the manufacturer and by authorised LUKAS dealers. When replacing components, only original LUKAS spare parts must be used (as detailed in the Spare Parts List) and instructions relating to the use of special tools, assembly procedures, safety aspects and testing must be complied with (see also the chapter entitled ‘Maintenance and Servicing’).
9.3 Repairs 9.3.1 Replacing the blades, protection hose and handle 1. Start by carefully cleaning the rescue equipment. 2. Next, close the blade arms so that the tips are almost touching. NOTE: The blade bolts are only accessible when the blade arms are almost touching 3. Remove the self-locking nut ‘A’ and push the pivot bolt ‘B’ out. D A C B 4. Slide the protection hose slightly away until the locking bolts ‘C’ are easily accessible. 5. Remove the retaining rings ‘D’ and push out bolt ‘C’.
8. Finally, remove the protection hose ‘H’ from the tool as shown. H 9. Unfasten the screws ‘J’ and remove them. J 10. Take the handle ‘K’ away in direction of the lever elements and also remove the washers ‘L’ underneath. K L 11. Assembly is carried out in the reverse order. NOTE: If only the blade arms need replacing, follow the procedure as far as Step 6 and then go on to Step 11. If the protection hose needs changing, follow the procedure as far as Step 8 and then go on to Step 11.
9.3.2 Labels All damaged and/or illegible labels (safety notices, type plate, etc.) must be renewed. Procedure: 1. Remove damaged and/or illegible labels. 2. Clean surfaces with industrial alcohol. 3. Attach new labels. Ensure that you attach the labels in the right position. If you are no longer sure about this, then please contact your authorised LUKAS dealer or LUKAS itself. 10.
