Quick-clamping Nut

For convenient changing of grinding tools with-
out the use of additional tools, you can use the
quick-clamping nut 13 instead of the clamping
nut 12.
The quick-clamping nut 13 may be used only
for grinding or cutting discs.
Use only a flawless, undamaged quick-clamp-
ing nut 13.
When screwing on, pay attention that the side
of the quick-clamping nut 13 with printing
does not face the grinding disc; the arrow must
point to the index mark 27.
Lock the grinder spin-
dle with the spindle
27
lock button 1. To tight-
en the quick-clamping
nut, firmly turn the
grinding disc in clock-
wise direction.
A properly attached,
undamaged quick-
clamping nut can be
loosened by hand
when turning the
knurled ring in anti-
clockwise direction.
Never loosen a tight
quick-clamping nut
with pliers. Always
use the two-pin span-
ner. Insert the two-pin spanner as shown in the
illustration.
