Mount the desired grinding accessory 1 (grind-
ing disc) in the correct rotation direction onto
the grinder spindle 4.
Place the clamping nut 11 onto the spindle
thread so that the central recess of the clamping
nut faces upward.
Tighten the clamping nut with two-pin spanner
10, while counter-holding the spanner surfaces
of the grinder spindle 4 with open-end spanner
14.
After mounting the grinding tool and before
switching on, check that the grinding tool is
correctly mounted and that it can turn free-
ly. Make sure that the grinding tool does
not graze against the protection guard or
other parts.
Removing a Grinding Disc
Grinding discs become very hot while work-
ing; do not touch until they have cooled.
Hold the grinder spindle 4 on the spanner sur-
faces with open-end spanner 14.
Unscrew the clamping nut 11 from the grinder
spindle with two-pin spanner 10, while counter-
holding the spanner surfaces with open-end
spanner 14.
Afterwards, pull the grinding tool and the
mounting flange from the grinder spindle.
Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Bosch Power Tools
Connection to the Power Supply
For operation of the power tools, a frequency
converter is required that generates three-
phase current with a frequency according to
that listed on the type plate.
Frequency converters are available in various
sizes, with different frequencies, secondary
voltages and rated outputs. The choice of the
frequency converter depends on the power
tools to be connected. When selecting a fre-
quency converter, contact your Bosch-specialist
shop for advice.
The machine is provided with a four meter long
specialty cable without plug. To put it into oper-
ation, the specialty cable must be equipped
with a four-pole CEE plug (identification colour
green).
Additionally, the machine can be equipped with
a commercially available motor protection
switch for protection against overload. The ad-
justment range of the motor protection switch
must cover the nominal current of the power
tool (see "Technical Data"). The motor protec-
tion switch must react in less than one second.
Please observe the safety warnings and assem-
bly instructions in the operating instructions
of the motor protection switch!
Mounting the CEE Plug (see figure F–G)
– Loosen the two screws 22 and pull the plug
insert 21 out of the plug housing of the CEE
plug 24.
– Cut off the plastic sleeve 25 according to the
diameter of the specialty cable of the power
tool and insert the specialty cable through
the CEE plug housing.
– Insert the four conductors through the cable
strain relief 20.
– Loosen the four small screws 23 in the plug in-
sert 21 and insert
the conductor ferrule of the brown L1 conduc-
tor into contact tube L1,
the conductor ferrule of the blue L2 conductor
into contact tube L2,
the conductor ferrule of the black L3 conduc-
tor into contact tube L3,
and the conductor ferrule of the green/yellow
conductor into the earthing contact tube
