Maintenance and Cleaning

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.
