The flange should not turn on the spindle when properly attached. - Place the grinding disc on the support flange (14). The grinding disc must lay flat on the supporting flange. The metal flange on the parting grinder disc must lay flat on the support flange. 6.3 Securing/Releasing the "Quick" clamping nut (depending on features) Securing the "Quick" clamping nut (1): Only attach the "Quick" clamping nut (1) to tools with "Metabo Quick System". These tools can be identified by the red spindle lock button 12 (4) with "M-Quick" logo Do not use the "Quick" clamping nut if the accessory has a clamping shank thicker than 7.1 mm! In this case, use the 2-hole nut (15) with 2hole spanner (16). - Lock the spindle (see chapter 6.1). - Position the "Quick" clamping nut (1) on the spindle (2) so that the 2 lugs engage in the 2 grooves on the spindle. 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 clamping nut (1): Only when the "Quick" clamping nut (1) is attached must the spindle be stopped using the red M-Quick spindle locking button (4)! - The machine continues to run after switching off. - Press in the M-Quick spindle locking button (4) just before the grinding disc stops. The "Quick" clamping nut (1) loosens itself by around half a turn and can be removed without additional effort or tools. 6.4 Securing/Releasing the 2-hole nut (depending on features) The 2 sides of the 2-hole nut are different. Screw the 2-hole nut onto the spindle as follows: See illustration C on page 2. - X) For thin grinding discs: The edge of the 2-hole nut (15) faces upwards so that the thin grinding disc can be attached securely. Y) For thick grinding discs: The edge of the 2-hole nut (15) faces downwards so that the 2-hole nut can be attached securely to the spindle. - Locking the spindle. Turn the 2-hole nut (15) clockwise using the 2-hole spanner (16) to secure. Releasing the 2-hole nut: - Lock the spindle (see chapter 6.1). Turn the 2-hole nut (15) anticlockwise using the 2-hole spanner (16) to unscrew. 7. Use 7.1 Adjusting the speed (depending on features) Set the recommended speed at the thumbwheel (8). (small number = low speed; large number = high speed) Cutting disc, roughing disc, cup wheel and diamond cutting disc: high speed Brush: medium speed Sanding plate: low to medium speed Note: We recommend using our angle polisher for polishing work. 7.2 Switching on and off Always guide the machine with both hands.
