• This wet/dry vacuum cleaner is designed to remove dry dirt and liquids.

• 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 60335-2-69.

• 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. Activities in enclosed spaces with low exposure in accordance with TRGS 519 number 2.8 or small-scale work in accordance with TRGS 519 number 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 outer enclosure, but also e.g. the cooling chamber, installation spaces for electrical equipment, the equipment itself, etc.). This is to be recorded in writing and signed by the technical expert.

• The flat fold filter (GF) 6.904-242.0 (material marking B) may only be used in combination with the safety filter bag 2.889-183.0.

• This device is suitable for commercial use,e.g. in hotels, schools, hospitals, factories, shops, offices, and rental companies.

The device automatically switches off when operated without a flat fold filter.

1. Unpack the device and install the accessories.

The device has 2 operating modes:

1. Industrial vacuum cleaner operation (power socket not used)

2. Dust removal operation (power socket used)

1. Connect the suction hose and attach a suction nozzle or connect to the dust generating device, depending on the operating mode.

The horn sounds when the air speed in the suction hose drops below 20 m/s.

1. Set the minimum flow rate (suction power) on the suction control of the tool adapter (infinitely adjustable) so that the horn stops.

Static charges are discharged through the earthed connection nozzles. This prevents sparking and electric shocks with electrically conducting accessories (included in the scope of delivery).

• The device is equipped with a safety filter bag with sealing cap, order no. 2.889-183.0 (5 pieces).

• Unused flat fold filters may only be stored and transported in their packaging (cardboard box).

• 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 automatically 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 and let it dry. Clean the electrodes with a brush. Clean the container with a moist cloth and dry it off.

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