Adjust the protective guard (9) such that sparking in
u
the direction of the operator is prevented.
Protective guard for cutting
Provide sufficient dust extraction when cutting stone.
u
The protective guard for cutting (18)/(17) is fitted in the
same way as the protective guard for grinding with a locking
screw (9) or the protective guard for grinding with a clamp-
ing lever (8).
For cutting, always use the protective guard for
u
cutting (18)/(17) or the protective guard for
grinding (9)/(8) together with the cover for
cutting (19).
Cover for cutting
Fit the cover for cutting (19) on the protective guard for
grinding (8)/(9) (see figure D/G): Swivel the lever back (➊).
Attach the cover (19) to the protective guard for
grinding (8)/(9) (➋). Press the lever firmly into place again
on the protective guard (8)/(9) (➌).
To remove the cover (see figure E/H), swivel the lever back
(➊). Remove the cover (19) from the protective guard (8)/
(9) (➋).
Extraction guard for cutting with a cutting guide
Place the extraction guard for cutting with a cutting
guide (34) on the spindle collar. Adjust the position of the
protective guard (34) to the requirements of the work pro-
cess and fasten the protective guard with the locking screw .
A suitable Bosch dust extractor can be connected to the ex-
traction guard with cutting guide (34). To do so, insert the
vacuum hose with dust extraction adapter into the provided
receiving connection of the extraction guard.
Note: The friction generated by the dust in the vacuum hose
and accessory during extraction causes an electrostatic
charge that the user may experience as static discharge (de-
pending on environmental factors and their physiological
state). Bosch generally recommends using an anti-static va-
cuum hose (accessory) to vacuum up fine dust and dry ma-
terials.
Hand guard
Always fit the hand guard (26) when working with the
u
rubber sanding pad (27) or with the cup brush/conical
brush/diamond annular cutter.
Attach the hand guard (26) to the auxiliary handle (5)/(6).
Standard auxiliary handle/low-vibration auxiliary handle
Screw the auxiliary handle (5)/(6) on the right or left of the
machine head depending on the working method.
Do not operate your power tool without the auxiliary
u
handle (5)/(6).
Do not continue to use the power tool if the auxiliary
u
handle (5)/(6) is damaged. Do not make any altera-
tions to the auxiliary handle (5)/(6).
The low-vibration auxiliary handle (6)
reduces vibration, enabling the tool to
be used safely and more comfortably.

Fitting the Abrasive Tools
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Note: Ensure that the clamping flange supplied (35) is
mounted correctly in accordance with figure C.
Make sure that the fitted O-ring (36) is not damaged and is
mounted correctly in accordance with figure C. Replace any
damaged O-rings (36).
Note: It is recommended to use the quick-clamping
nut (16). When using the clamping nut (15), expect more
force to be required to loosen it.
Clean the grinding spindle (25) and all parts to be mounted.
Lock the grinding spindle with the spindle lock button (1)
before clamping and releasing the abrasive tools.
Do not press the spindle lock button while the grind-
u
ing spindle is moving. The power tool may become dam-
aged if you do this.
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-ro-
tation arrow on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on the clamping
nut (15) and tighten with the two-hole spanner.
After fitting the abrasive tool, check that the abrasive
u
tool is fitted correctly and can turn freely before
switching on the power tool. Make sure that the abras-
ive tool does not brush against the protective guard or
other parts.
Quick-clamping nut
To change the abrasive tool easily without having to use any
additional tools, you can use the quick-clamping nut (16) in-
stead of the clamping nut (15).
The quick-clamping nut (16) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (16) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut (16) is not facing the grinding disc;
the arrow must be pointing towards the index mark (37).
