USER MANUAL 1055 HTC KRESS

/2" x 20 UNF 3,2gk thgieW Use The drill is universally suitable for use as a drill and screwdriver in wood, metal and plastic. Due to the low speed it is ideally suited for mixing and stirring thin and thick liquid materials, for drilling with very large drill ø and for screwing screws into frames and raw plugs. Safety instructions and prevention of accidents Before operating the machine, please read through the operating instructions completely, follow the Safety In- structions in this manual as well as the general Safety Instructions for Power Tools in the accompanying booklet. Warning! This drill generates an extremely high amount of torque. Always hold the drill firmly with both hands! Use auxili- ary handles supplied with the tool. Loss of control can cause personal injury. Exercise particular caution when stirring thick and hig- hly viscous materials. Ensure that the container is in good condition and fixed in such a way that it cannot be turned itself by the mixer! Caution! The unit may only be connected to the mains using the original mains cable module. Pay attention to the jamming moment of the machine, e. g. if the drill jams or if the drill hits concrete reinforcing steel and jams! Before fitting tools in the chuck or drill spindle dis- connect the machine from the power supply, or re- move the mains cable module (3) from the grip using the locking device button (4)! Do not work with materials which contain as- bestos! Outside power sockets must be protected with re- sidual-current-operated circuit-breakers (r.c.c.b.). Do not drill holes into the housing to label the machine. The protective insulation will be bridged. Please use self-adhesive labels. Always lead cables away towards the back of the machine. Double Insulation Our equipment is designed in accordance with European re- gulations (EN standards) for the utmost safety of the user. Machines with double insulation always carry the internatio- nal symbol. The machines do require earthing. A two-core cable is sufficient. The machines are interference-suppressed in accordance with EN 55014. Initial operation Before the first operation check that the mains voltage cor- responds to that given on the machine nameplate. Electronic speed control. This machine has an integrated full wave electronic control circuit built into the switch (1). The required speed may be se- lected with the adjusting wheel (e.g. for serial screw drilling). Position A = lowest speed Position G = highest speed The full wave electronic unit with tacho signal calculation keeps the torque constant. Low rotational speed and high torque makes the drilling machine ideal wherever high power is a requirement, for example: – when mixing or stirring particularly thick and highly vis- cous materials, – when drilling with very large diameters, – when inserting screws in frames and wall plugs. Ensure that the drill is not allowed to jam for longer than 2–3 seconds. Longer jamming can lead to motor damage. Important! Continuous operation under strong load and low speed can overheat the motor. Allow the motor to cool down in no-load when set at a high speed! Electronic torque control (Torque-Control) Thumbwheel (6) can be used to determine the amount of torque acting upon the drill spindle. 1 = low torque 10 = maximum torque When the preselected torque is reached during drilling, the unit switches off and remains oft. Changing direction of rotation (main rotation – clockwise) The direction of rotation of the spindle is altered by the re- versing switch (2). R = Clockwise (Right) L = Anticlockwise (Left) Important! Press the rotational direction switch (2) in each case to the stop on the housing, i. e. until it can be felt to engage. The reversing switch can be easily operated using the thumb and index or middle finger from both sides. Attention! Change direction of rotation only when the motor has ceased turning! When in middle LOCK position, the reversing switch prevents the accidental activation of the full wave electronic switch (1), for example when changing tools or assembling/disassembling the drill chuck. Quick-change chuck This chuck has been specially developed for use on per- cussion drills. The chuck has a release safety lock which prevents any unintentional release of drilling tool even at high impact frequencies. Operation by turning collar asusual to stop point. Engagement of clamping force safety lock for subsequent operation is clearly heard and felt. Clamping and releasing of chuck by holding the locking ring. If a faulty chuck has to be replaced, please check whether the chuck is secured to the drill spindle with a safety screw. This screw must be removed first (Caution! Lefthan- ded screw! Turn clockwise!). Screw off the drill chuck as shown in the picture (with an open-end wrench). For reassembly, proceed in the opposite direction. Caution: Before fitting a new chuck please clean the end faces on the chuck and drill spindle. Tighten the new chuck securely (30 Nm). Secure the chuck with the safety screw is there is one (Tighten the safety screw in anti-clockwise direction). Caution! It is still possible, especially when there is no safety screw, that the chuck comes off the drill spindle when it is turning in the anticlockwise direction. For this rea- son, when changing the chuck ensure that it is fitted onto the spindle perfectly. Caution! Put the reversing switch (2) in the LOCK position be- fore disassembling and reassembling the drill chuck, disconnect the machine from the power supply, or re- move the mains cable module (3) from the grip using the locking device button (4). Always make sure that the chosen speed is correct for the purpose for which you are using the machine. When drilling match speed with type of material and drill. Use tool steel twist drills for soft materials such as wood and plastics; high speed twist drills for steel and iron. When drilling match speed to material and the diameter of the drill. Use tool steel twist drills for soft materials such as wood and plastics; high speed twist drills for steel and iron. Also make sure that the drill chuck key is never fastened to the drill with chains, strings or by similar means. Be sure that the workpiece cannot be taken along by the drill. Maintenance The machine's motor has life-time lubrication and requires no special maintenance. However, should you operate the machine on a continuous basis over long periods of time we recommend that you send us the machine for thorough cleaning and an inspection. This will spare you unneces- sary repair expenses and increase the machine's service life. If you always clean the ventilator of dust after each operation, the motor will enjoy an ever longer service life. Uniform ventilation is essential for a long service life. Replacing carbon brushes Our service personnel will do this and all other servicing work fast and professionally. Mains cable Replace damaged mains cables immediately. This is an uncomplicated procedure thanks to the latest cable mo- dule (3). Press both locking buttons (4) and pull the cable module (3) out of the grip. Insert and lock the new mains cable module. Cables with different lengths are available as optional accessories. Only use the mains cable module for KRESS power tools! Do not attempt to operate other electrical ap- pliances with it! Auxiliary handle For safety reasons the side handle should always be used when working with the drill. It guarantees safe, wander-free guidance of the drill, and at the same time precise adjust- ment of the drilling depth with the depth stop. Tighten the draw spindle on the auxiliary handle properly. This is the only way to ensure that the auxiliary handle cannot turn on the collar or come off the appliance. Standard accessories Side handle with depth stop Noise/vibration information Measured values correspond with EN 60745. Typically the A-weighted noise levels of the machine are: Sound pressure level: 78 dB (A) Sound power level: 89 dB (A) Measurement uncertainty: K = 3 dB (A) The noise level can exceed 85 dB(A) during operation.Wear hearing protection!
