Actuate the spindle lock button only
when the grinder spindle is at a stand-
still.
Otherwise, the machine may become
damaged.
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
reducers 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
arrow on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on
the clamping nut
10
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 freely. 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
8
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
8
is
mounted.
Flap disc

For operations with the flap disc, always
mount the hand guard 14.
Rubber sanding plate
��
��
For operations with the rubber sanding
plate 15, always mount the hand guard 14.

and tighten with the
two-pin spanner.
Cup brush/disc brush
��
��
For operations with the cup brush/wheel
brush, always mount the hand guard 14.
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 with-
out 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 23.
Lock the grinder spin-
dle with the spindle
lock button
1
. To
tighten the quick-
clamping nut, firmly
turn the grinding disc
in clockwise 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.
