Quick-clamping nut
To change the abrasive tool easily without having to use any additional tools, you can use the quick-clamping nut (14) instead of the clamping nut (13).
- The quick-clamping nut (14) may be used only for grinding or cutting discs or disc brushes with hole diameter 22.2 mm.
Only use quick-clamping nuts (14) that are in good working order and not damaged.
When screwing on, make sure that the printed side of the quick-clamping nut (14) is not facing the grinding disc; the arrow must be pointing towards the index mark (26).
Press the spindle lock button (1) to lock the grinding spindle. To tighten the quick-clamping nut, turn the grinding disc firmly clockwise.
If the quick-clamping nut has been attached correctly and is not damaged, you can loosen it by hand by turning the knurled ring anticlockwise. If the quick-clamping nut is stuck, do not attempt to loosen it with pliers – always use the two-pin spanner. Position the two‑pin spanner as shown in the figure.
