Overload Protection
When overloaded, the motor comes to a stop.
Relieve the load on the machine immediately
and allow to cool down for approx. 30 seconds
at the highest no-load speed.
Working Advice
Clamp the workpiece if it does not remain
stationary due to its own weight.
Do not strain the machine so heavily that it
comes to a standstill.
Do not touch diamond cup wheels before
they have cooled. Diamand cup wheels be-
come very hot while working.
Apply the power tool to the workpiece only
when switched on.
Move the machine with a circular motion or al-
ternately in length and crosswise direction over
the workpiece/surface applying moderate pres-
sure. For removal of coatings, the machine can
also be guided at a small angle to the workpiece
surface without a reduction of the dust extrac-
tion capacity.
Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
In extreme conditions, always use dust ex-
traction as far as possible. Blow out ventila-
tion slots frequently and install a residual
current device (RCD). When working metals,
conductive dust can settle in the interior of
the power tool. The total insulation of the
power tool can be impaired.
A blunt diamond cup wheel 12 can be reground
by briefly grinding abrasive material (e.g. lime-
sand brick).
Please store and handle the accessory(-ies)
carefully.
Bosch Power Tools
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts order,
please always include the 10-digit article
number given on the type plate of the machine.
Changing the Brush Collar
To ensure optimal dust extraction, change a
worn brush collar 8 in good time.
Using a screwdriver, carefully pry out the brush
collar 8 at the openings of the brush guide with
the diamond cup wheel 12 mounted. Use the
diamond cup wheel for leverage while prying
out.
Carefully push a new brush collar 8 to the stop
into the brush guide. When inserting the new
brush collar, pay attention that the ends of the
brush collar are not positioned in one of the
openings of the brush guide.
Service Indicator 5
When the carbon brushes are worn out, the ma-
chine switches itself off. This is indicated ap-
prox. 8 hours beforehand by the lighting or
blinking of the service indicator 5. The machine
must then be sent to an after-sales service
agent. Addresses are listed in the Section "Af-
ter-sales Service and Customer Assistance".
