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).

- Note: You can use this appliance to vacuum all types of dust up to dust class L.
- Note: The appliance is suited as industrial vacuum cleaner to take up dry, non-combustible dusts with AGW values greater than or equal to 1 mg/m3.
When vacuuming up fine dust, an additional fleece filter bag, a dust bag or a membrane filter (special accessory) can additionally be used.

Care and maintenance

DANGER
First pull out the plug from the mains before carrying out any tasks on the machine. Dust extracting machines are safeguards for the prevention or elimination of hazards defined in the regulations of BGV A1.

In order to carry out maintenance work, the user must disassemble, clean and service the unit, in so far as this is possible without endangering maintenance personnel and other persons. 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.

WARNING
Safety equipment for preventing hazards must be serviced and maintained regularly. This means that the manufacturer’s staff or persons trained by the manufacturer must check the equipment for proper functioning at least once a year, i.e. check for leaks, filter damage, etc.
ATTENTION
Risk of damage! Do not use detergents containing silicone to clean.

No outside help is required for carrying out basic maintenance and cleaning.
The appliance surface and the inside of the container should be cleaned regularly using a damp cloth.
