en ENGLISH Do not use the "Quick" clamping nut if the accessory has a clamping shank thicker than 8mm! In this case, use the clamping nut (12) with 2hole spanner (13). Only use the "Quick" clamping nut when undamaged and in perfect operating condition : the arrow must point to the notch on the outer ring (see illustration on page 2). - Lock the spindle (see chapter 7.1). - Fit the "Quick"clamping nut (1) on the spindle (3). See illustration on page 2. - Tighten the "Quick"clamping nut by turning clockwise by hand. - Turn the grinding wheel firmly clockwise to tighten the "Quick"clamping nut. Releasing the "Quick" clamping nut (1) : - Lock the spindle (see chapter 7.1). - Turn the "Quick"clamping nut (1) anticlockwise to unscrew. 7.4 Securing/Releasing the clamping nut (depending on features) Securing the clamping nut (12): The 2 sides of the clamping nut are different. Screw the clamping nut onto the spindle as follows: See illustration D on page 2. - A) For thin grinding wheels: The edge of the clamping nut (12) faces upwards so that the thin grinding wheel can be attached securely. B) For thick grinding wheels: The edge of the clamping nut (12) faces downwards so that the clamping nut can be attached securely to the spindle. - Lock the spindle. Turn the clamping nut (12) clockwise using the 2-hole spanner (13) to secure. Releasing the clamping nut: - Lock the spindle (see chapter 7.1). Turn the clamping nut (12) anticlockwise using the 2-hole spanner (13) to unscrew. 8. Use 8.1 Switching On and Off Always guide the machine with both hands. Switch on first, then guide the accessory towards the workpiece. The machine must not be allowed to draw in additional dust and shavings. When switching the machine on and off, keep it away from dust deposits. After switching off the machine, only place it down when the motor has come to a standstill. Avoid inadvertent starts: always switch the tool off when the plug is removed from the mains socket or if there has been a power cut. In continuous operation, the machine 16 continues running if it is forced out of your hands. Therefore, always hold the machine with both hands at the intended handles, take a secure stance and concentrate on the work. See illustration A on page 2. Torque activation Switching on: Slide the lock (6) in the direction of the arrow and press the trigger (7). Switching off: Release the trigger (7). Continuous operation (depending on features) Switching on: Slide the lock (6) in the direction of the arrow, press the trigger (7) and keep it pressed. The machine is now switched on. Now slide the lock (6) in the direction of the arrow once more to lock the trigger (7) (continuous operation). Switching off: Press the trigger (7) and release. 8.2 Working instructions Grinding: Press down the machine evenly on the surface and move back and forth so that the surface of the workpiece does not become too hot. Roughing: position the machine at an angle of 30° 40° for the best working results. Separating: Always work against the run of the disc (see illustration). Otherwise there is the danger of the machine kicking back from the cut out of control. Guide the machine evenly at a speed suitable for the material being processed. Do not tilt, apply excessive force or sway from side to side. Sanding: Press down the machine evenly on the surface and move back and forth so that the surface of the workpiece does not become too hot. Wire brushing: Press down the machine evenly. 9. Cleaning Motor cleaning: blow compressed air through the rear ventilation slots of the machine regularly, frequently and thoroughly. Here, the machine must be held firmly. Button (8) for adjustment of the handle (depending on features): Occasionally blow compressed air through the button (when pressed, in all 3 main handle positions). 10. Troubleshooting Machine with "X" in the model designation: - Overload protection: The electronic signal display (5) lights up and the load speed decreases dramatically. The motor temperature is too high! Run the machine in idling until it cools down and the electronic signal display switches off. - Overload protection: The electronic signal display (5) lights up and the load speed
