Hand Guard
 For operations with the rubber sanding plate 19 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 18.
The hand guard 18 is fastened with the auxiliary handle 9.
Mounting the Grinding Tools
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Clean the grinder spindle 10 and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er spindle with the spindle lock button 3.
 Actuate the spindle lock button only when the grinder
spindle is at a standstill. Otherwise, the machine may be-
come 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 attention that the di-
rection-of-rotation arrow on the diamond 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
14 and tighten with the two-pin spanner; see Section "Quick-
clamping Nut ".
Ensure that the abrasive product is firmly seated, so that it
does not twist away from the spindle in the runout of the pow-
er tool.
 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 oth-
er parts.
A plastic part (O-ring) is fitted around
the centring collar of mounting flange
12. If the O-ring is missing or dam-
aged, the mounting flange 12 must be
replaced before resuming operation.
Flap Disc
 For operations with the flap disc, always mount the
hand guard 18.
Bosch Power Tools
Rubber Sanding Plate
 For operations with the rubber sanding plate 19, al-
ways mount the hand guard 18.
See graphics page for the mounting sequence.
Screw on the round nut 21 and tighten with the two-pin span-
ner.
Cup Brush/Disc Brush
 For operations with the cup brush/wheel brush, always
mount the hand guard 18.
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. Tight-
en the cup brush/disc brush with an open-end spanner.
Quick-clamping Nut
For convenient changing of grinding tools without the use of
additional tools, you can use the quick-clamping nut 15 in-
stead of the clamping nut 14.
 The quick-clamping nut 15 may be used only for grind-
ing or cutting discs.
 Use only a flawless, undamaged quick-clamping nut 15.
 When screwing on, pay attention that the side of the
quick-clamping nut 15 with printing does not face the
grinding disc; the arrow must point to the index mark
37.
Lock the grinder spindle with
the spindle lock button 3. To
tighten the quick-clamping
37
nut, firmly turn the grinding
disc in clockwise direction.
A properly attached, undam-
aged quick-clamping nut can
be loosened by hand when
turning the knurled ring in
anticlockwise direction.
Never loosen a tight quick-
clamping nut with pliers.
Always use the two-pin
spanner. Insert the two-pin
spanner as shown in the
illustration.
