Safety instructions

DANGER

• When the outgoing air is carried back into the room, a sufficient ventilation rate L in the room must be ensured. To comply with the required limit values the carried back volume flow must be 50%of the fresh air volume flow (room volume VR x ventilation rate LW) at maxi-mum. Without a specific ventilation system the following applies: LW=1h–1.
• Only persons trained in the use of the machine and the handling of substances for which the machine is to be used including training in the safe disposal of the sucked-in material may use the ma-chine.
• This appliance contains harmful dust. Evacuation and maintenance work, including the disposal of the dust collection containers, may only be performed by specialists who wear the appropriate protective equipment.
• Do not use the appliance without the complete filtering system.
• Please follow the safety regulations applicable to the materials that are to be treated.
• Press the parking brake to the steering

Start up

• WARNING
  The flat pleated filter must always be in place while vacuuming.

•   WARNING
  Do not vacuum without the filter elements; otherwise, the suction motor can get dam-aged and this can be hazardous to health on account of increased release of fine dust particles.

Anti-static system

Static charge is deflected by providing earthing to the connection nozzles. This prevents the formation of sparks and cur-rent shocks due to attachments (option) with electrical conductivity.

Dry vacuum cleaning

• NT 30/1: The device is equipped with a fleece filter bag with a lock cap, order no. 2.889-154.0 (5 units).

Suitable precautions include decontamination before the unit is disassembled. Pre-cautions must be taken for local filtered forced air ventilation at the place where the unit is disassembled, the cleaning of the maintenance surface and suitable protection of the personnel.
• The outside of the unit should be cleaned thoroughly and any harmful substances removed. Alternatively, a sealed coating may be applied before the unit is removed from the danger area. All unit parts are to be considered contaminated when they are removed from the danger area. To avoid distribution of the dust, you must take the appropriate measures.
• In the framework of maintenance and repair work all contaminated objects that cannot be cleaned satisfactorily must be disposed of. Such objects must be disposed of in impermeable bags in accordance with the valid provisions for the disposal of such waste.
