Maintenance and Service
Maintenance and Cleaning
Before any work on the machine (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
For safe and proper working, always keep
the machine and ventilation slots clean.
Replacing the Carbon Brushes (see figure E)
Check the length of the carbon brushes approx.
every 2–3 months and replace the carbon
brushes if required.
Never replace only a single carbon brush!
Criteria for replacement of the carbon brushes:
A dotted or broken line is visible on one of the
large side surfaces of each carbon brush. When
either of both carbon brushes is used up to this
line, then both carbon brushes should be re-
placed immediately in order to protect the ar-
mature against possible damage.
Note: Use only carbon brushes supplied by
Bosch and intended specifically for your product.
– Unscrew the caps 15 using a suitable screw-
driver.
– Replace the spring-loaded carbon brushes
14 and screw the caps back on again.
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.
