the grinder spindle threads. Tighten with an

Quick Clamping Nut
Instead of the clamping nut 9, the quick-clamping
nut 10 (accessory) can be used. Grinding tools
can then be mounted without using tools.
The quick-clamping nut 10 may be used only
for grinding and cutting discs.
Use only a flawless, undamaged quick-clamp-
ing nut 10.
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 16.
