Nilfisk-ALTO ATTIX 791-2M/B1 Picking up liquids, Electrical components, Before start-up

Precautions and safety regulations when using the vacuum cleaner

Conductive extraction equip- ment, e.g. extraction hoods on machines and conductive parts of machining equipment (e.g. equipment in protective class

II)that are not earthed through the cleaner, must be earthed in some other way to prevent elec- trostatic charges.

The cleaner is not suitable for extraction on machining equip- ment in operation that could produce sources of ignition.

Before start-up

Inspect power cord regularly to detect signs of damage, e.g. cracks or ageing.

If the power cord is damaged, it must be replaced by Nilfisk- Alto-Service or an electrician to avoid danger before use of the vacuum cleaner is continued.

Use only the type of power cord specified in the operating manual.

Do not damage the power cord (e.g. by moving over it or pulling or crushing it).

Disconnect the power cord by pulling the plug only (do not pull or tug the power cord).

Inspect the vacuum cleaners to ensure that they are in proper condition. Plugs and couplings in power cords must at least have splash protection.

Never use the vacuum cleaner if the filter element is damaged.

Picking up liquids

If foam develops or liquid emerges, stop work immediately and empty the dirt tank.

Regularly clean the float that limits the water level and check it for damage.

ATTIX 791-2M/B1

When dust removers are used, the rate at which air is ex- changed in the room must be adequate if the exhaust air from the vacuum cleaner is blown into the room (please observe regu- lations valid in your country).

Before starting work, the operat- ing staff must be informed on

–use of the vacuum cleaner

–risks associated with the ma- terial to be picked up

–safe disposal of the picked up material.

See section 5 for information on handling liquids and (hazard- ous) dust.

Electrical components

Check the rated voltage of the vacuum cleaner before con- necting it to the mains supply system. Ensure that the voltage shown on the rating plate cor- responds to the voltage of the local mains power supply.

If you are using an extension cord, use only those specified by the manufacturer or higher quality ones (see section 9.4 „Technical data“).

It is recommended that the vacuum cleaner should be con- nected via a residual current circuit breaker. This stops the supply of electricity if the leak- age current to earth exceeds 30 mA for 30 ms or it has an earth tester circuit.

When using an extension lead, check the minimum cross-sec- tions of the cable:

Cable length	Cross section
m
	<16 A	<25 A
up to 20 m	ø1.5mm²	ø2.5mm²
20 to 50 m	ø2.5mm²	ø4.0mm²

Arrange the electrical parts (sockets, plugs and couplings) and lay down the extension lead so that the protection class is maintained.
