Maintenance and Cleaning

Pull the plug out of the socket before carrying out any work on the power tool.

To ensure safe and efficient operation, always keep the power tool and the ventilation slots clean.

In order to avoid safety hazards, if the power supply cord needs to be replaced, this must be done by Bosch or by an after-sales service centre that is authorised to repair Bosch power tools.

Replacing the carbon brushes (see figure B)

Check the length of the carbon brushes around every 2–3 months and replace both carbon brushes if required.

Never replace only a single carbon brush.

Note: Only use carbon brushes supplied by Bosch and intended 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.

The criteria for replacing the carbon brushes: A dashed or dotted line is present on one large side of the carbon brush. If one of the two carbon brushes has been worn down to this line, both carbon brushes should be replaced immediately in order to protect the commutator from any potential damage.
