[. . . ] The vacuum pump has to run during the complete operation, it is to be placed in such a position that you can monitor the pressure gauge at all times. It is mandatory to check that the foot plate is firmly affixed to the surface before drilling is started. Fixing by means of dowels in concrete For brickwork, anchor must be used. Drill a hole (Ø 15) 50 mm deep (A), into which the dowel M 12 (B) is to be placed; insert and secure the dowel with the doweling tool (C). [. . . ] Operations In order to operate the tool safely, please observe the following notes: Details of the work area !Keep the work area free of everything which could obstruct operations. Lay the power cable 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 operating and maintenance Whenever possible, keep a free space for operating and maintenance of about 2 m around the drill position, 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 foundations are not damaged. Make sure not to damage any water or gas pipes or power lines during drilling. Make sure not to touch any metal parts of the tool when drilling in walls or floors, where power lines might be lying in water. 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 drop downwards. If the drill core could cause damage when dropping down, set up a cordoned off area. In order to achieve an exact centering of the drill bit, minimize the forward travel of the drill bit during the first centimetre of cutting depth. If the speed is too high, the diamond segments will become blunt in a short time. Remove the bolt, which holds the support at a 90° angle, from the foot plate. Loosen the thumb screw between base and support and swivel the support to the desired angle. At the beginning, drill at a low speed, as the drill bit enters into the material with only a part of its cutting edge. If the drill speed or pressure is too high, the drill bit may become erratic. Open the water supply and make sure that the water reaches the segments before you start drilling. [. . . ] Remove the core with suitable pliers or drill a hole into the core, insert a lifting screw and pull the core out. Move the machine holder with the core drill upwards until it locks in the final position. Always keep the drilling stand clean, especially the drill support with the gear and the 4 sliding pieces in the holder of the machine. In order to allow the free movement of the pinion shaft it should be slightly lubricated. [. . . ]
