Mounting the Grinding Tools
Before any work on the power tool itself,
pull the mains plug.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
Clean the grinder spindle 6 and all parts to be
mounted.
For clamping and loosening the grinding tools,
lock the grinder spindle with the spindle lock
button 2.
Actuate the spindle lock button only when
the grinder spindle is at a standstill. Other-
wise, the power tool 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 reduc-
ers or adapters.
When using diamond cutting discs, pay attention
that the direction-of-rotation arrow on the dia-
mond cutting disc and the direction of rotation 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
wrench; 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.
An O-ring (plastic part) is insert-
ed in the mounting flange 8
around the centering collar. If
the O-ring is missing or is dam-
aged, it must in all cases be re-
placed (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 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 wrench.
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 wrench.
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-clamping
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.
