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.
The housing of the dust extractor must be thoroughly vacuumed and wiped clean with a damp cloth, or treated with sealant, before the dust extractor can be removed from the hazardous area. All dust extractor parts must be considered to be contaminated when taken from the hazardous area, appropriate precautions must be taken. All parts not sufficiently cleaned during maintenance/repair must be disposed of (in impermeable bags).
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 processes described in the Assembly chapter form part of the maintenance routine. 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.
A technical inspection 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 and to check that the dust extractor is tight and that the control unit is functioning correctly.
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.
The suction power is dependent on the condition of the filter. Therefore, the filter should be cleaned regularly.
If the flat-pleated filter (28) becomes damaged, replace it immediately.
