[. . . ] When drilling through ceilings, secure the area below as the drill core may drop downwards. Make sure that the tool is switched off before connecting to the power outlet. The tool should be switched off and disconnected from power when not under supervision, in case of mounting or dismounting the tool, in case of voltage drops or when fixing or mounting accessories. Do not use when parts of the housing, the switch, power cable or plug are damaged. [. . . ] 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. Make sure not to damage gas or water pipes or power lines during drilling. Make sure that the drill core will not hurt anybody or cause damage to anything when falling out. When drilling through holes through ceilings, secure the area from below, as the drill core may fall downwards. If the drill core could cause damage when falling down, set up a construction to hold back the drill core. The following possibilities exist for mounting the P-54190: Fixing the mount in concrete by means of dowels For brickwork, expending anchor must be used. Drill a hole (Ø 15) 50 mm deep (A), into which the dowel M12 (B) is to be placed; insert the dowel and secure the dowel with the doweling tool (C). Fix the washer (E) and finally the fastening nut (F) on the quick action clamping screw (D). Before and after tightening the nut (F) the adjustable screws have to be adjusted Do check whether the mount is installed safely and firmly. Fixing the mount on the floor by vacuum Do not use vacuum fixing on walls or over-head!Vacuum fixing may only be used if the area to be drilled is level, free of pinholes and cracks, otherwise this method cannot be applied. Screw the plug-in nipple into the foot plate, to which previously seal strip has been applied. [. . . ] Electronic: An LED is built into the housing in order to alert the operator in case of excessive forward pressure. if the red signal is disregarded for a longer period of time , the tool will be switched of automatically by the electronic device. After the first 150 operating hours the transmission oil must be exchanged. The oil exchange will greatly increase the life cycle of the transmission. [. . . ]
