The protection guard 12 may be turned only upon
actuation of the release lever 1! Otherwise 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.
Extraction Hood
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 15
with a sanding sheet 16. 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 han-
dle.
Do not continue to use an auxiliary handle if it is
damaged.
Hand Guard
For operations with the rubber sanding plate 15
or with the cup brush/wheel brush/flap disc,
always mount the hand guard 14.

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.
B Actuate the spindle lock button only when the
grinder spindle is at a standstill. 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 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 ".
After mounting the grinding tool and before
switching on, check that the grinding tool is cor-
rectly mounted and that it can turn freely.
Flap Disc
For operations with the rubber sanding plate 15
or with the cup brush/wheel brush/flap disc,
always mount the hand guard 14.
Place the special mounting flange (article number
2 605 703 028) and the flap disc on the grinder spin-
dle 6. Screw on the clamping nut 10 and tighten with
the two-pin spanner.
Rubber Sanding Plate
For operations with the rubber sanding plate 15
or with the cup brush/wheel brush/flap disc,
always mount the hand guard 14.
See graphics page for the mounting sequence.
Screw on the round nut 17 and tighten with the two-pin
spanner.
