[. . . ] S If the mains cable is damaged or cut through while working, do not touch the cable but immediately pull the mains plug. S Connect machines that are used in the open via a residual current device (RCD) with an actuating current of 30 mA maximum. S When working with the machine, always hold it firmly with both hands and provide for a secure stance. [. . . ] Press the protection guard onto the spindle collar until the collar of the protection guard faces against the flange of the machine and the encoding keys engage in the circular groove at the spindle collar. For work with the rubber sanding pad 13 or with the cup brush 16/disc brush/flap disc, mounting the hand guard 12 (accessory) is recommended. Use only grinding tools with a permissible speed at least as high as the no-load speed of the machine. Grinding and cutting discs become very hot while working; do not touch until they have cooled. For clamping and loosening the grinding tools, lock the grinder spindle 5 with the spindle lock button 4. Actuate the spindle lock button 4 only when the grinder spindle is at a standstill!Adjust the protection guard 6 in such a manner that sparks are not emitted in the direction of the operator. Note: Encoding keys on the protection guard 6 ensure that only a protection guard that fits the machine type can be mounted. The mounting hole diameter must fit the mounting flange 8 without play. When using a diamond cutting disc, take care that the direction-of-rotation arrow on the diamond cutting disc and the direction of rotation of the machine (direction-of-rotation arrow on the machine head) agree. Screw on the clamping nut 10 and tighten with the two-pin spanner (see Section "Quick-clamping Nut"). Depending on the application, remove the protection guard 6 and mount the hand guard 12. The grinding tool must be able to be screwed onto the grinding spindle 5 until it rests firmly against the grinder spindle flange at the end of the grinder spindle threads. Instead of the clamping nut 10, the quick-clamping nut 11 (accessory) can be used. The quick-clamping nut 11 may be used only for grinding and cutting discs. When screwing on, take care that the side with printing does not point to the grinding disc. If the O-ring is missing or is damaged, it must in all cases be replaced (Order No. After mounting the grinding tool and before switching on, check that the grinding tool is correctly mounted and that it can turn freely. [. . . ] Noticeable decreasing work progress and circular sparking are indications of a diamond cutting disc that has become dull. The machine head can be rotated with respect to the machine housing in 90° steps. In this manner, the On/Off switch can be brought to an advantageous handling position for special working situations, e. [. . . ]
