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.
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.
- Wear a protective mask of protection class FFP2 or higher and disposable protective suit according to the relevant provisions when carrying out maintenance and cleaning of the dust extractor. Maintenance and cleaning may only be carried out by persons with proof of expertise.
- Do not use compressed air to clean the dust extractor. The filter or other components may become damaged.
At least once a year a technical inspection of the dust extractor must be carried out by the manufacturer or someone who has been trained (e.g. to check for filter damage, to check that the dust extractor is tight and that the control unit is in perfect working order).
In addition to this, the effectiveness of the filter must be inspected at least annually in accordance with EN 60335-2-69, 22.AA.201.2. National requirements may also necessitate more frequent inspection.
If the filter is no longer deemed effective, it must be replaced and the test must be repeated.
- All parts that may have come into contact with the hazardous substances must be considered contaminated.
- Vacuum, wipe down and seal the outside of the dust extractor thoroughly before removing it from the area containing the hazardous substances.
- Only clean, dismantle and perform maintenance on the dust extractor if this can be done without endangering yourself or other persons. Wear personal protective equipment for cleaning and maintenance tasks. Undertake the work in a well ventilated room.
- First clean the outside of the dust extractor before dismantling it.
- All parts of the dust extractor that cannot be adequately cleaned must be disposed of in impermeable bags. Please observe the applicable regulations for the disposal of such waste.
- Clean the maintenance area after completing the work.
The suction power is dependent on the condition of the filter. Therefore, the filter should be cleaned regularly.
