Protection Guard for Grinding
Place the protection guard 7 onto
the spindle collar of the machine
until the encoding keys of the pro-
tection guard agree with the spin-
dle collar. Press and hold the re-
lease lever 1 while doing this.
Press the protection guard 7 onto
the spindle collar until the shoul-
der 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 protec-
tion guard 7 to the requirements
of the work process. For this, press the release lever 1 up-
ward and turn the protection guard 7 to the required position.
Always adjust the protection guard 7 in such a manner
that all 3 red cams of release lever 1 engage into the
corresponding notches of the protection guard 7.
Adjust the protection guard 7 in such a manner that
sparking is prevented in the direction of the operator.
The protection guard 7 may be turned only upon actua-
tion 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 7 ensure
that only a protection guard that fits the machine type can be
mounted.
Protection Guard for Cutting
For cutting with bonded abrasives, always use the pro-
tection guard for cutting 11.
Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 11 is mounted in the same
manner as the protection guard for grinding 7.
Cutting Guide with Dust Extraction Protection Guard
The cutting guide with dust extraction protection guard 18 is
mounted in the same manner as the protection guard for
grinding 7.
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.
Hand Guard
For operations with the rubber sanding plate 14 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 13.
The hand guard 13 is fastened with the auxiliary handle 5.
Mounting the Grinding Tools
Before any work on the machine itself, pull the mains
plug.
Bosch Power Tools
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 grind-
er spindle with the spindle lock button 2.
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
10 and tighten with the two-hole spanner.
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.
Flap Disc
For operations with the flap disc, always mount the
hand guard 13.
Rubber Sanding Plate
For operations with the rubber sanding plate 14, al-
ways mount the hand guard 13.
See graphics page for the mounting sequence.
Screw on the round nut 16 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 13.
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.
