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.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
Replacing the Carbon Brushes (see figure B)
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 replaced im-
mediately in order to protect the armature against possible
damage.
Note: Use only carbon brushes supplied by Bosch and intend-
ed specifically for your product.
Unscrew the caps 4 using a suitable screwdriver.
Replace the spring-loaded carbon brushes 8 and screw the
caps back on again.
