1. Hazard classes We distinguish between various categories of safety notes. 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. Moreover, the operating instructions are intended to help the safe use of LUKAS products. 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. Do not carry out any changes (additions or conversions) to the equipment without obtaining the prior approval of LUKAS. Observe all safety and danger notes on the equipment and in the operating instructions. All safety and danger notes on the equipment are to be kept complete in a legible condition.
The equipment 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 equipment, ensure that the function and the safety of the equipment are not impaired by the effects of stark external temperatures or that the equipment is damaged in any way.
3. Proper 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 chainset. LUKAS handheld combi tools can basically be used to cut, pull, open, squeeze and lift objects.
4. Description of the functions 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 Control of working direction The working direction is adjusted before actuating the hand lever by turning the rotary knob to the desired switching end point. Turn to the right Turn to the left = = Blade arms close Blade arms open - - Cutting Spreading 5.2 Movement of the blade arms Actuate the hand lever (up and down movement) to move the two blade arms in the set working direction.
6. Cutting, spreading, pulling and squeezing 6.1 Safety instructions 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, regular safety inspections according to the GUV legal accident insurance regulations (Gesetzlichen Unfallversicherung) are mandatory.
During cutting, the gap between the blade tips (in the crosswise direction) of 3 mm (0.12 inches) must not be exceeded, otherwise the blade may break: 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.
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 fit 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, affix and use the chain sets.
7. Dismantling the equipment / deactivation following operation 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 equipment. REMARK: 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.
Inspections to be carried out: Visual inspection • Opening width of the blade arms on the tips (see chapter “Technical data”), • General tightness (leaks), • Ease of movement of the hand lever, • Ease of movement of the rotary knob, • Existence and stability of handle, • Ease of rotational movement of tool head through 360°, • Labels completely existent and legibly, • Covers in perfect condition, • Torque control of the pivot bolt (torque MA see "Technical data"), • Blade arms free of tears and without any
9.2 Preventative service 9.2.1 Note concerning care The exterior of the equipment is to be cleaned from time to time in order to protect it from external corrosion. Oil is to be applied to the metallic surfaces. 9.2.2 Functional and loading test If there is any doubt regarding the safety or reliability of the equipment, a function and load test must also be performed. LUKAS offers appropriate test equipment to this end. 9.3 Repairs 9.3.1 Replacing the blades, protection hose and handle 1.
7. Fold in the lever elements (G). G 8. Finally, remove the protection hose (H) from the tool as shown. H 9. Unfasten the screws (J) and remove them. J 10. Slide the handle (K) towards the lever elements to remove it and also remove the washers (L) underneath. K L 11. Assembly is carried out in the reverse order. REMARK: If you only want to change the blade arms, carry out the work up to step 6 and step 11. If you want to change the protection hose, carry out the work up to step 8 and step 11.
CAUTION! The nut of the pivot bolt and the pivot bolt itself will be adapt together by a special procedure, therefore they have only be changed as a set by usage of a new set! Because of the special procedure an unscrewing of the nut while working will be minimized and a resulting blade crack will be prevented. The nuts can be unscrewed and thigtend up to 10 times without affecting the service performance! 9.3.2 Labels All damaged and/or illegible labels (safety notices, type plate, etc.
