• This vacuum cleaner is intended for the wet and dry cleaning of floor and wall surfaces.
• This device is suitable for vacuuming dry, non-flammable dusts that are harmful to health from machines and devices; dust class H as per EN 603352-69.
• Industrial vacuums and portable dust removal devices in accordance with Technical Rule 519 (TRGS 519) Appendix 7.1 may be used for the following applications: 1. In enclosed spaces, activities with low exposure in accordance with TRGS 519 number 2.8 or smallscale work in accordance with TRGS 519 No. 2.10. 2. Cleaning work. In the Federal Republic of Germany, the regulations in TRGS 519 (Technical Rules for Hazardous Substances) apply to asbestos vacuum cleaners.
• After using the asbestos vacuum cleaner in the sealed-off area as per TRGS 519, the asbestos vacuum cleaner may no longer be used in the “white area”. Exceptions are only permitted if the asbestos vacuum cleaner has been completely decontaminated beforehand by a specialist in accordance with TRGS 519 No. 2.7 (“completely” means not only the case, but also e.g. the cooling chamber, installation spaces for electrical equipment, the operating equipment itself, etc.).

General

• We recommend switching off the “Automatic filter dedusting” function when vacuuming wet dirt with the crevice nozzle or the upholstery nozzle (optional), or when sucking mainly water out of a container.
• The device switches off automatically when the maximum fluid level is reached.
• When vacuuming non-conductive liquids (e.g. drill emulsion, oils and grease) the device does not au- tomatically switch off when the container is full. The filling level must be continuously monitored and the container emptied on a timely basis.
• On completion of wet vacuum cleaning: Clean the flat fold filter using the dedusting function. Clean the electrodes with a brush. Clean the container with a moist cloth and dry it off.

Clip connection
The suction hose is equipped with a clip system. All accessory parts with a nominal width of 35 mm can be connected. Illustration L
