Bosch AdvancedGrind 18V-80 Notice Originale page 27

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 (18) 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.
Mounting flange for grinding spindle M 14:
A plastic part (O-ring) is fitted around the cent-
ring collar in the mounting flange (14). If the
O-ring is missing or damaged, the mounting
flange (14) must be replaced before operation
can resume.
Approved abrasive tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
-1
The permissible speed [min ] 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
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.
Working advice
Rough grinding
Always use the protective guard for grinding (11)
u
when rough grinding with bonded abrasives.
Never use cutting discs for rough grinding.
u
When rough grinding, the protective guard for
u
cutting (12) or the protective guard for grinding (11)
with a fitted cover for cutting (13) can impact the
workpiece and lead to a loss of control.
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.
The protective guard for cutting (12) or the protective
u
guard for grinding (11) with a fitted cover for cutting (13)
must be used when using bonded discs which are ap-
proved for cutting and grinding.
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.
