User manual KRESS 802 WS

[. . . ] Persons working with an angle grinder must always wear protective goggles!When mounting 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 the use of the spring flange in the operating instructions. Intermediate shims may not be used on conical or offset grinding wheels. [. . . ] Initial operation Before the first operation check that the mains voltage corresponds to that given on the machine nameplate. By allowing the machine to run idle, the motor will cool down very quickly and work can continue. 1 Switching machine on and off The machine is started by sliding switch ring (1) in the direction of the arrow. the toggle lever (2) will then automatically engage in the foremost slide position. Pushing on the tilted front edge (3) of the lever (2) disengages the switch and causes the switch ring (1) to rotate back into its original position automatically. Full cycle control electronics with electronic motor protection monitoring (safety electronics) (1052 WSE) The provision of full cycle control electronics with built-in motor-tacho generator offers the following advantages: The motor accelerates gradually to the preselected speed, thereby protecting the operator and the gears, and extending the service life of the machine. Electronic overload protection If an excessive load occurs which could damage the motor, the integrated motor monitor reduces the rotation speed of the angle grinder. The machine must be disengaged - and ideally removed briefly from the work piece - so that full power becomes available again. electronic control with motor-tacho generator The adjusting wheel (20) of the full cycle control electronics allows the preselection of optimal rotation speeds for all grinding , cutting and polishing work. When under load the motor-tacho generator provides an increased power supply. the preselected rotation speed is held constant. The working speed required is dependent on various factors such as, for example, the type, hardness and characteristics of the material being worked, and the type and condition of the grinding, cutting and polishing tools to be used. The optimal setting should be determined in tests 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/mounting of the protection cover Turn the protection cover (4) until the cams (5) on the protection cover (4) align with the safety groove (6). The protection cover (4) can now be easily lifted off the gear flange. the protection cover is mounted in the opposite order. Cutting and grinding may only be done with the protection cover on!Adjusting the protection cover The protection cover (4) can be moved into any position required by loosening the pan head screw (7). Tightening the pan head screw (7) locks the protection cover (4) into position. When working with the protection cover swung back and the curved handle mounted, make sure that the protection cover is never swung over the handle side. 4 Mounting instructions for roughing and cutting wheels The two examples of usage show how thick (5­10 mm) and thin (1­6 mm) grinding wheels are to be fastened to the spindle end with the clamping flange (18).
