Dust/Chip Extraction

Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Do not load the power tool so heavily that it comes to a
u
stop.
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Exercise caution when cutting slots in structural walls;
u
see the "Information on structural design" section.
Clamp the workpiece if it is not secure under its own
u
weight.
If the power tool has been subjected to a heavy load,
u
continue to run it at no-load for several minutes to
cool down the accessory.
Do not use the power tool with a cut-off stand.
u
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
If the power tool becomes electrostatically charged, the
built-in electronics will switch the power tool off. To start
the power tool, push the unlocking lever (7) forwards and
then push the on/off switch (6) up.

Working advice

Rough grinding
Never use cutting discs for rough grinding.
u
The best rough grinding results are achieved with a set angle
of 30° to 40°. Move the power tool back and forth with mod-
erate pressure. This will ensure that the workpiece does not
become too hot or discolour and that grooves are not
formed.
Bosch Power Tools
Surface grinding with flap disc
Always use the protective guard for grinding (11)
u
when grinding with the flap disc.
The flap disc (accessory) enables you to machine curved
surfaces and profiles. Flap discs have a considerably longer
service life, lower noise levels and lower grinding temperat-
ures than conventional grinding discs.
Surface grinding with sanding disc
Always fit the hand guard (23) when working with the
u
rubber sanding pad (24).
Grinding with a sanding disc can be done without a protect-
ive guard.
See the graphics page for fitting instructions.
Screw on the round nut (26) and tighten it with the two-pin
spanner.
Cup brush/disc brush/conical brush
Always use the protective guard for grinding (11)
u
when brushing with disc brushes. Brushing with cup
brushes/conical brushes can be performed without
the protective guard.
Always fit the hand guard (23) when working with the
u
cup brush or conical brush.
The wires of the disc brush can get caught on the pro-
u
tective guard and break, if the maximum permitted di-
mensions of the disc brushes are exceeded.
See the graphics page for fitting instructions.
The cup brush/conical brush/disc brush with M14 thread
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/conical
brush/disc brush with an open-ended spanner.
Cutting metal
Always use the protective guard for cutting (12) when
u
cutting with bonded abrasives.
When carrying out abrasive cutting, use a moderate feed
that is suited to the material being machined. Do not exert
pressure on the cutting disc and do not tilt or swing the
power tool.
Do not attempt to reduce the speed of a cutting disc coming
to a stop by applying pressure from the side.
Cutting Stone (see figure A)
Provide sufficient dust extraction when cutting stone.
u
Wear a dust mask.

The power tool must always
work in an up-grinding mo-
tion. Otherwise there is a
risk that it will be pushed
uncontrolled out of the cut.
For best results when cut-
ting profiles and rectangular
tubing, start at the smallest
cross section.
