The tool may only be used in conjunction with a suitable diamond drilling stand (P-54190). Safety precautions Important directions and safety precautions are represented by symbols on the tool. [. . . ] The DBM 230 is equipped with a mechanical 3-gears transmission in oil bath. Adjust the rotation speed of the engine to the drill diameter (for details see identification plate). Turn the gear switch to a faster/slower gear until it arrests. Gears must only be shifted when the engine is at stand-still. It may be necessary to support the switching operation by slightly turning the lead screw. Never use force, shift gears only when the motor decelerates or is at stand-still!The tool is heavy and may heat up during operations or sharpening. You could burn your hands, cut, tear or squash yourself on the segments. Before working on the equipment pull the power plug. Raise the engine retainer with the core drill until it arrests in the final position. Always wear protective gloves when changing tools. Never remove the drill bit by hitting it (with a hammer) as this will cause damage to the core drill tool. Putting some waterproof grease on the drill spindle thread and a copper ring placed between the spindle and the drill bit will further facilitate the removal of the drill bit. Operating the drill unit In order to safely operate the tool, please observe the following notes: Details to the work area !Keep the work area free of everything which could obstruct operations. Install power lines in such a way that any damage by the drill can be avoided. Make sure to always keep the work area in view and to be able to reach all necessary operating elements and safety installations. Keep other persons away from your work area in order to avoid accidents. Space requirements for operations and maintenance Keep a free space for operations and maintenance of about 2 m around the drill, whenever possible, so that you can work safely and have immediate access in case of a malfunction. When drilling into blocks make sure that they are well fixed and fastened. Before drilling into load-bearing elements, make sure that the foundation are not damaged. Follow the instructions of the specialists responsible for the planning. [. . . ] At the start of drilling, use low drill speed as only a portion of the drill bit touches the surface. If the drill speed or pressure is too high the drill bit may become erratic. When drilling overhead take special care that no water enters into the tool. In case you notice during drilling that the advance speed becomes very slow, that you have to employ increased pressure and that the water emerging from the borehole is clear and mixed with metal splinters you probably have hit reinforcement iron.
