# 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.
