User manual KRESS 1050 FME

[. . . ] Make sure that the grinding disc is mounted and fixed correctly before use. Run the tool at an idling speed of 30 s in a safe location and stop it immediately if it starts to vibrate significantly or if you notice other problems. if such a situation occurs , check the machine to determine the cause of the problem. For grinding tools with thread inserts, make sure that the thread is long enough to accommodate the spindle length. [. . . ] Before you start operating the machine, check whether the mains voltage corresponds to the information on the machine's tool identification plate. SWITCHING ON THE MACHINE Push the on/off switch 6 forward until the tilt lever is automatically locked into place. to clamp the tool , you lock the spindle 1 by pressing the locking button 5. You can remove the tool by continually turning the open-ended spanner. rEPLACING A COLLET CHUCK An annular spring 3 holds the collet chuck 2 in the locknut 1. By forceful turning, you can loosen the collet chuck 2 from the locknut 1. Press down heavily to lock the new collet chuck into place in the locknut 1. Lightly unscrew the locknut to protect the thread on the spindle but never tighten it if a tool is not being used. This might compress the collet chuck too much, which could lead to it becoming damaged. When you use a drill stand or a mill/drill unit (possibly with a milling table), you must refer to the notes in the instructions for use provided there. Also note that you must add the alignment fences as far as possible on the milling cutter, the hand deflector (screen) must be set down as tightly as possible on the workpiece surface and, for milling work, you must always use equipment that can guarantee safe use of the tool, for example, alignment fence, auxiliary bearings, automatic feeders or a non-return block for milling work. The feed direction of the tool must always be the opposite of the circulation direction of the milling cutter (counter direction): Due to its low measurements and light weight, the milling and grinding motor is also extremely suitable for a lot of hands-free work. As a milling motor, the machine must only be operated using the appropriate attachments (tray router, laminate trimmers or stationary). The grinding tools are stored in such a way that they are not damaged (cracks in the grinding tool, damaged tool shanks and so on, mean that the user's life is in danger). Before you use new grinding tools, you must carry out a test run for at least 5 minutes without the device being overloaded. Very high rotational speeds result in the tools wearing rapidly and consequently in low service lives for the tools!When you use other milling tools, the steady rotational speeds per minute indicated on the manufacturer's rotating tools must not be exceeded!WORKING WITH FLEXIBLE SHAFTS Due to its high rotational speed, the milling and grinding motor is also highly suitable as a drive motor for flexible shafts. Note here that the maximum rotational speed of the flexible shaft must at least correspond to the rotational speed of the motor. The following are integrated into these full-wave electronics with an built-in tachogenerator: SOFT STARTER The starting current limitation reduces the starting current. the motor revs up slowly until it reaches the preselected rotational speed. Only use milling, drill, polishing and grinding tools that are approved for high-speed operation -1 (30, 000 min ). [. . . ] This electrical tool has been designed with high precision and was approved after undergoing strict quality control checks in the factory. We are therefore able to guarantee free servicing of any production or material faults which arise in the 24 months after the date of sale to the purchaser. We reserve the right to repair defective parts or else replace them with new parts. The guarantee will be rendered void if the device is used improperly, mistreated or opened up by unauthorised repair personnel. [. . . ]
