Quick Clamping Nut
Instead of the clamping nut 12, the quick-clamp-
ing nut 13 (accessory) can be used. Grinding
tools can then be mounted without using tools.
The quick-clamping nut 13 may be used only
for grinding and cutting discs.
Use only a flawless, undamaged quick-clamp-
ing nut 13.
When screwing on, take care that the side
with printing does not point to the grinding
disc. The arrow must point to the index
mark 30.
