Assembly
Mounting the Protective Devices
Before any work on the machine itself, pull
the mains plug.
Protection Guard for Sanding
Place the protection guard 12
onto the spindle collar as
shown in the illustration. The
triangle marks on the protec-
tion guard must correspond
with the respective marks on
the gear case.
Press the protection guard 12
onto the spindle collar until the
shoulder of the protection
guard is seated against the
flange of the machine, and turn
the protection guard until it can
clearly be heard to engage.
Adjust the position of the protection guard 12 to the
requirements of the work process. For this, press the
release lever 1 upward and turn the protection guard
12 to the required position.
Adjust the protection guard 12 in such a man-
ner that sparking is prevented in the direction
of the operator.
The protection guard 12 may be turned only
upon actuation of the release lever 1! Other-
wise the power tool may not continue to be
used under any circumstances and must be
taken to an after-sales service agent.
Note: The encoding keys on the protection guard 12
ensure that only a protection guard that fits the machine
type can be mounted.
Protection Guard for Cutting
For cutting metal, always work with the pro-
tection guard for cutting 13.
For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 20.
The protection guard for cutting 13 is mounted in the
same manner as the protection guard for sanding 12.
Extraction Hood for Sanding
The extraction hood 7 can be used for low-dust sand-
ing of paint, varnish and plastics in conjunction with
the carbide grinding head 9 or the rubber sanding
plate 16 with a sanding sheet 17. The extraction hood
7 is not suitable for working metals.
A suitable Bosch vacuum cleaner can be connected
to the extraction hood 7.
The extraction hood 7 is mounted in the same manner
as the protection guard 12. The brush collar is
exchangeable.

Auxiliary Handle
Operate your machine only with the auxiliary
handle 5.
Screw the auxiliary handle 5 on the right or left of the
machine head depending on the working method.
Vibration-dampening Auxiliary Handle
The vibration-dampening auxiliary handle reduces the
vibrations, making operation more comfortable and
secure.
Do not make any alterations to the auxiliary
handle.
Do not continue to use an auxiliary handle if it
is damaged.
Hand Guard
For operations with the rubber sanding plate
16 or with the cup brush/wheel brush/flap
disc, always mount the hand guard 15.
The hand guard 15 is fastened with the auxiliary han-
dle 5.
Mounting the Grinding Tools
Before any work on the machine 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 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 attention that
the direction-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 10 and tighten with the two-pin spanner;
see Section "Quick-clamping Nut ".
