User manual KRESS 800 SX

[. . . ] Allow the motor to cool down in no-load when set at a high speed!Torque-selection + electronic safety system (Model 1050 SXC only) The integrated full wave electronic system with tachometer maintains a constant rpm speed. The system's preselectable power regulation (torque selection) allows the torque to be regulated to meet different requirements, for example, in the case of serial screw drilling. regulate the torque with the adjustment wheel (4) on the grip. [. . . ] 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. Please make sure to use the correct screwdriver inserts. 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. When cutting threads, use low speeds only. 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. This screw must be removed first (Attention!The chuck can be loosened and unscrewed by lightly hitting a hexagon socket key (Allen key) which has been fitted in the chuck. it is refitted by repeating the procedure backwards. 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). 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 speeds are necessary for polishing and grinding. When drilling match speed with type of material and drill. 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.
