I 0 I 0 en ENGLISH 7.3 Securing/releasing the (tool-free) clamping nut (depending on features) Only tighten the (tool-free) clamping nut (2) manually. For the machine to operate, the clip (1) must always lie flat on clamping nut (2) . To secure the (tool-free) clamping nut (2): Do not use the (tool-free) clamping nut if the accessory has a clamping shank thicker than 6 mm! In this case, use the clamping nut (17) with 2hole spanner (18). - Lock the spindle (see chapter 7.1). - Flip up the clip (1) on the clamping nut. - Fit the clamping nut (2) on the spindle (4). See illustration on page 2. - (1)Tighten the clamping nut on the clip manually in a clockwise direction. - Flip down the clip (1) again . To release the (tool-free) clamping nut (2) : - Lock the spindle (see chapter 7.1). - Flip up the clip (1) on the clamping nut. - Unscrew the clamping nut (2) , turning it anticlockwise manually . Note: If the clamping nut is very tightly secured (2), you can also use a 2-hole spanner to unscrew it. Avoid switching on the machine accidentally: always switch it off when the battery pack is removed from the machine. In continuous operation, the machine continues running if it is forced out of your hands. Therefore, always hold the machine with both hands using the handles provided, stand in a safe position and concentrate. Machines with slide switch: 6 Switching on: Push the slide switch (6) forward. For continuous activation, now tilt downwards until it engages. Switching off: Press the rear end of the slide switch (6) and release. Machines with Paddle Switch  (with dead man function): (machines with the designation WP...) 14 13 7.4 Securing/releasing the clamping nut (depending on features) Securing the clamping nut (17):  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 (17) faces upwards so that the thin grinding wheel can be attached securely. B) For thick grinding wheels:  The edge of the clamping nut (17) faces downwards so that the clamping nut can be attached securely to the spindle. - Lock the spindle. Turn the clamping nut (17) clockwise using the 2-hole spanner (18) to secure. Releasing the clamping nut: - Lock the spindle (see chapter 7.1). Turn the clamping nut (17) anticlockwise using the 2-hole spanner (18) 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 16 it down when the motor has come to a standstill. Switching on: Slide the switch-on lock (13) in  the direction of the arrow and press  the trigger (14). Switching off: Release the trigger (14). 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. Cutting-off: 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 Clean the dust filter regularly: remove and clean with a jet of compressed air.
