Rubber sanding pad
Always fit the hand guard (15) when working with the
u
rubber sanding pad (17).
See the graphics page for fitting instructions.
Before fitting the rubber sanding pad (17), place the two
spacer discs (16) on the grinding spindle (4).
Screw on the round nut (19) and tighten with the two-pin
spanner.
Cup brush/disc brush
Always fit the hand guard (15) when working with the
u
cup brush or disc brush.
See the graphics page for fitting instructions.
The cup brush/disc brush must be screwed onto the grinding
spindle until it rests firmly against the grinding spindle flange
at the end of the grinding spindle thread. Tighten the cup
brush/disc brush with an open-ended spanner.
Quick-clamping nut
To change the abrasive tool easily without having to use any
additional tools, you can use the quick-clamping nut (11) in-
stead of the clamping nut (9).
The quick-clamping nut (11) may be used only for
u
grinding or cutting discs.
Only use quick-clamping nuts (11) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut (11) is not facing the grinding disc;
the arrow must be pointing towards the index mark (24).

Bosch Power Tools
Press the spindle lock but-
ton (1) to lock the grinding
spindle. To tighten the
quick-clamping nut, turn
the grinding disc firmly
clockwise.
If the quick-clamping nut
has been attached correctly
and is not damaged, you
can loosen it by hand by
turning the knurled ring an-
ticlockwise. If the quick-
clamping nut is stuck, do
not attempt to loosen it
with pliers – always use
the two-pin spanner. Posi-
tion the two‑pin spanner as
shown in the figure.
Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
The permissible speed [min -1 ] or the circumferential speed
[m/s] of the abrasive tools used must at least match the val-
ues given in the table.
It is therefore important to observe the permissible rota-
tional/circumferential speed on the label of the abrasive
tool.

Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Start-Up
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
When operating the power tool using a mobile generator that
does not have sufficient reserve capacity or an adequate
voltage control system with inrush current boost converter,
loss of performance or atypical behaviour may occur upon
switch-on.
