Grinding/Cutting Disc
Pay attention to the dimensions of the grinding
tools. The mounting hole diameter must fit the
mounting flange without play. Do not use reduc-
ers or adapters.
When using diamond cutting discs, pay atten-
tion that the direction-of-rotation arrow on the
diamond cutting disc and the direction of rota-
tion of the machine (see direction-of-rotation ar-
row on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on
the clamping nut 11 and tighten with the two-
pin spanner; see Section "Quick-clamping Nut ".
After mounting the grinding tool and before
switching on, check that the grinding tool is
correctly mounted and that it can turn free-
ly. Make sure that the grinding tool does
not graze against the protection guard or
other parts.
Mounting flange for grinding
spindle M 14: An O-ring (plas-
tic part) is inserted in the
mounting flange 9 around the
centring collar. If the O-ring is
missing or is damaged, it must
in all cases be replaced (article
number 1 600 210 039) before
the mounting flange 9 is mounted.
Mounting flange for grinding spindle M 10: The
mounting flange can be used on both sides.
Flap Disc
For operations with the flap disc, always
mount the hand guard 15.
Rubber Sanding Plate
For operations with the rubber sanding
plate 16, always mount the hand guard 15.
See graphics page for the mounting sequence.
Screw on the round nut 18 and tighten with the
two-pin spanner.
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.
Bosch Power Tools
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 with-
out the use of additional tools, you can use the
quick-clamping nut 12 instead of the clamping
nut 11.
The quick-clamping nut 12 may be used only
for grinding or cutting discs.
Use only a flawless, undamaged quick-clamp-
ing nut 12.
When screwing on, pay attention that the side
of the quick-clamping nut 12 with printing
does not face the grinding disc; the arrow must
point to the index mark 23.
Lock the grinder spin-
dle with the spindle
23
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.
