[. . . ] For the mounting of grinding wheels, only spring flanges of the same size and with bearing surfaces of the same shape may be used. please note the points regarding use of the spring flange in the operating instructions. Intermediate shims may not be used on conical or offset grinding wheels. [. . . ] Pushing on the tilted front edge (3) of the lever (2) disengages the lever and causes the switch ring (1) to rotate back into its original position automatically. Full-wave control electronics with electronic motor protection monitoring The following advantages are integrated into the full-wave electronics: Soft start The start-up current limiter reduces the start-up current. The motor accelerates slowly to the preselected speed, protecting the operator and the gearbox and extending the service life of the machine. If the load becomes heavy enough to endanger the motor, the integrated motor monitor reduces the speed of the angle grinder. The load on the machine must be relieved ­ preferably by briefly disengaging it from the work piece ­ in order to provide you with the full power of the machine again. electronic control system The setting wheel (20) of the full-wave control electronics permits the selection of optimum speeds for all grinding , cutting and polishing work. The working speed required is dependent on a number of factors such as, for example, type, hardness, constitution of the material to be worked on, type and condition of the grinding, cutting and polishing tools being used. The ideal speed should be determined by trials at the beginning of a job. 2 When grinding, the best results are achieved if you work at a setting angle of approx. 3 Disassembly/Assembly of the protection cover If the protection cover (4) has to be removed, proceed as follows: Unscrew the two screws (5) and remove the counterflange (6). The protection cover (4), annular ring (7) and limit stop washer (8) can now be lifted off. Adjusting the protection cover Depending on the use, the protection cover can be swung back to the stop cams (9). When working with the protection guard swung back and the curved handle mounted, make sure that the protection cover is never swung over the handle side. 4 Mounting the curved handle Depending on the use and the user's needs, the curved handle (10) can be mounted in three positions. To mount the curved handle in the middle of the top of the gearbox head, proceed as follows: Place the curved handle (10) with the distance holder (12) on the unit so that the curved handle screw (13) lies above the screw opening in the gearbox head (11). Then screw the curved handle (10) onto the gearbox head (11) by turning the locking handle (14) clockwise until the curved handle (10) is fastened tightly.
