Approved Abrasive Tools; Dust/Chip Extraction; Working Advice - Bosch AdvancedGrind 18V-80 Manual Original

A plastic part (O-ring) is fitted around the cent-
ring collar in the hub flange (14). If the O-ring
is missing or damaged, the hub flange (14)
must be replaced before operation can re-
sume.
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.
Assembly with Clamping Nut (18)
(UniversalGrind 18V-75)
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 (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.
