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 (23) when working with the
u
rubber sanding pad (24) or the cup brush (27).
Attach the hand guard (23) to the auxiliary handle (9)/(10).
Standard auxiliary handle/low-vibration auxiliary handle
Screw the auxiliary handle (9)/(10) 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 (9)/(10).
Do not continue to use the power tool if the auxiliary
u
handle (9)/(10) is damaged. Do not make any altera-
tions to the auxiliary handle (9)/(10).
The low-vibration auxiliary handle
(10) reduces vibration, enabling the
tool to be used safely and more com-
fortably.
Fitting the Abrasive Tools
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.
Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Clean the grinding spindle (22) and all the parts to be fitted.
Lock the grinding spindle with the spindle lock button (2)
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
To secure a grinding/cutting disc, use the clamping
u
nut (18) or the quick-clamping nut with bar (19).
Assembly with Quick-clamping Nut (19)
(AdvancedGrind 18V-80)
Pay attention to the dimensions of the abrasive tools. The
diameter of the hole must match that of the mounting flange.
Do not use an adapter or reducer.
When using diamond cutting discs, make sure that the direc-
tion of rotation arrow on the diamond cutting disc corres-
ponds to the direction of rotation of the machine (see direc-
tion of rotation arrow on the housing).
See the graphics page for fitting instructions.
Use the quick-clamping nut (19) to secure the grinding/cut-
ting disc without the need for additional tools.
The quick-clamping nut (19) may be used only for
u
grinding or cutting discs.

Only use quick-clamping nuts (19) that are in good
u
working order and not damaged.
When screwing on, make sure that the printed side of
u
the quick-clamping nut (19) is not facing the grinding
disc.
the spindle in the runout of the power tool.
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.
Press the spindle lock but-
ton (2) to lock the grinding
spindle. To tighten the
quick-clamping nut (19),
fold up the bar and turn the
quick-clamping nut firmly
clockwise. Then fold down
the bar to secure the quick-
clamping nut. It is not suf-
ficient to tighten the disc
along the edge.
Quick-clamping nuts (19)
that are properly secured
and not damaged can be re-
moved by hand. To do this,
fold up the bar and turn the
quick-clamping nut firmly
anticlockwise. If the quick-
clamping nut is stuck, do
not attempt to loosen it with
a tool – always use a two-
pin spanner.
After fitting the hub flange
and the grinding/cutting
disc, the free thread length
of the grinding spindle must
be at least 4 mm.
Ensure that the abrasive
tool is firmly seated, so that
it does not twist away from
