additional tools, you can use the quick-clamping nut (13) in-
stead of the clamping nut (12).
The quick-clamping nut (13) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (13) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the

You can use all the abrasive tools mentioned in these operat-

The permissible speed [rpm] or the circumferential speed

ues given in the table.
It is therefore important to observe the permissible rota-

not attempt to loosen it
with pliers – always use
the two-pin spanner. Posi-
tion the two‑pin spanner as
