[. . . ] As a result it is necessary to adjust the torque initially by making a few test screw drillings. Use The drill is universally applicable for percussion drilling in rock, drilling and putting screws into wood, metal, and synthetics, and for tapping. Safety instructions and prevention of accidents Before operating the machine, please read through the operating instructions completely, follow the Safety Instructions in this manual as well as the general Safety Instructions for Power Tools in the accompanying booklet. The machine may jam, for example, when the machine is at an angle or when the drill bit comes into contact with reinforcing steel! [. . . ] Thus, the motor and gear are protected against overload, impulsive gearwheel loading is ruled out. quick-change chuck This chuck has been specially developed for use on percussion drills. The chuck has a release safety lock which prevents any unintentional release of drilling tool even at high impact frequencies. Engagement of clamping force safety lock for subsequent operation is clearly heard and felt. Use as a screwdriver Screwdriver inserts (bits) can fitted directly into the chuck. The electronic controls are sensitive and should be handled with utmost care to prevent any breaking of tap ­ particularly when cutting threads into blind holes. Before disassembling and reassembling the drill chuck, disconnect the machine from the power supply, or remove the mains cable module (6) from the grip using the locking device button (7). Before removing and mounting the drill chuck, always move the reversing switch (3) to the LOCK position. By doing so, you eliminate the risk of accidentally triggering the full wave switch (1). If a faulty chuck has to be replaced, please check whether the chuck is secured to the drill spindle with a safety screw. The chuck can be loosened and unscrewed by lightly hitting a hexagon socket key (Allen key) which has been fitted in the chuck. Caution: Before fitting a new chuck please clean the end faces on the chuck and drill spindle. Secure the chuck with the safety screw is there is one (Tighten the safety screw in anti-clockwise direction). 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 reason, when changing the chuck ensure that it is fitted onto the spindle perfectly. Always make sure that the chosen speed is correct for the purpose for which you are using the machine. High speed drilling in steel and stone will cause premature tool wear. Use tool steel twist drills for soft materials such as wood and plastics; carbide-tipped stone drills for stone and concrete; high speed twist drills for steel and iron. Also make sure that, using a gear-rim-chuck, the drill chuck key is never fastened to the drill with chains, strings or by similar means. 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 unnecessary 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.
