# Maintenance and Cleaning

- Pull the plug out of the socket before cleaning or performing maintenance on the vacuum cleaner, making tool adjustments, changing accessories or putting away the vacuum cleaner. This safety measure prevents the vacuum cleaner from being started accidentally.

- To ensure safe and efficient operation, always keep the dust extractor and the ventilation slots clean.

- Wear a dust mask when servicing and cleaning the vacuum cleaner.

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.

For the user to carry out maintenance, the dust extractor needs to be disassembled, cleaned and maintained as far as this is possible without endangering maintenance personnel or other persons. Before disassembly, the dust extractor should be cleaned to prevent any potential hazards. The room/enclosure in which the dust extractor is disassembled should be well ventilated. Wear personal protective equipment while carrying out maintenance. After completing maintenance, the maintenance area should be cleaned.
An inspection regarding the dust extraction capability must be carried out at least once a year by the manufacturer or someone who has been trained, e.g. to check for filter damage, that the dust extractor is tight and that the control unit is functioning correctly.
Class L vacuum cleaners which were located in dirty environments should have their exteriors, as well as all their components, cleaned or treated with sealant. When performing maintenance and repair work, all dirty parts that cannot be cleaned satisfactorily must be disposed of. Such parts must be disposed of in impermeable bags in accordance with the valid provisions for disposing of such waste.

- Clean the housing of the dust extractor occasionally with a damp cloth.
