# Maintenance and Cleaning

- Remove the battery from the fan before carrying out work on the fan (e.g. assembly, cleaning, etc.). The battery should also be removed for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.

Keep the fan clean to ensure good, safe operation.

If the battery is no longer working, please contact an authorised after-sales service agent for Bosch power tools.

Regularly clean the fan and the grille in front of the ventilation slots. How often cleaning needs to be carried out will depend on the application environment and the application time.

Regularly blow out the interior of the fan head, the propeller and the motor housing area with dry compressed air.

Use a clean cloth for cleaning. Under no circumstances should you clean the fan with brake fluid, petrol, products based on crude oil or strong solvents.

Do not use cleaning pads made of plastic or steel wool. You may permanently compromise the surface structure.

Never clean the fan with sharp and/or abrasive cleaning products. You may damage the surface of the tool.
