# Maintenance and Cleaning

- Before carrying out any work on the power tool (e.g. maintenance, tool change etc.), remove the battery from the power tool. There is risk of injury from unintentionally pressing the on/off switch.

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

After each use, clean the application tool, the rotary hammer adapter GFA 18-H with tool holder, and the ventilation slots of the power tool.
