Cup Brush/Disc Brush
For operations with the cup brush/wheel
brush, always mount the hand guard 15.
See graphics page for the mounting sequence.
The cup brush/disc brush must be able to be
screwed onto the grinder spindle until it rests
firmly against the grinder spindle flange at the
end of the grinder spindle threads. Tighten the
cup brush/disc brush with an open-end span-
ner.
Quick-clamping Nut
For convenient changing of grinding tools without
the use of additional tools, you can use the quick-
clamping nut 11 instead of the clamping nut 10.
The quick-clamping nut 11 may be used only
for grinding or cutting discs.
Use only a flawless, undamaged quick-clamp-
ing nut 11.
When screwing on, pay attention that the side
of the quick-clamping nut 11 with printing
does not face the grinding disc; the arrow must
point to the index mark 22.
Lock the grinder spin-
dle with the spindle
22
lock button 2. 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.
