Symbols used to mark

instructions

Before using the

vacuum cleaner,

always read the

operating instruc-

tions and keep

them readily

available.

This symbol is

used to mark

safety instruc-

tions that must

be observed to

prevent damage

to the vacuum cleaner and its

performance.

This symbol is

used to mark

safety instruc-

tions that must

be observed to

prevent damage to persons.

This symbol in-

dicates tips and

instructions to

simplify work and to ensure safe

operation.

For your own safety Only allow the vacuum cleaner

to be used by persons who have

been trained in its use and who

have been explicitly authorized

to use it.

Despite its simple handling the

vacuum cleaner is not suitable

for children.

The use of the vacuum cleaner

is subject to valid national regu-

lations. Besides the operating

instructions and the binding

accident prevention regulations

valid in the country of use, ob-

serve recognized regulations for

safety and proper use.

Do not use any unsafe work

techniques.

Purpose and intended use The vacuum cleaners described

in this operating manual are

suitable for

– commercial use, e.g. in

hotels, schools, hospitals,

factories, shops, offices and

rental businesses

– for separation of dust with an

exposure limit of greater than

1 mg/m³

– to pick up flammable, dry dust

in zone 22 (ATEX regulation

94/9/EG, II 3D T4 IP54)

The following materials should

not be picked up by the vacuum

cleaner:

– hot materials (burning ciga-

rettes, hot ash, etc.)

– flammable, explosive, ag-

gressive liquids (e.g. petrol,

solvents, acids, alkalis, etc.)

– mixtures of flammable dusts

with liquids

– explosive substances or

substances considered to

be similar in §1 of the law on

explosives

– flammable dusts with an ex-

tremely low minimum ignition

energy <1 mJ (also observe

national regulations).

– Highly reactive dusts or dusts

with a high affinity to oxygen

For dusts like titanium and mag-

nesium additional requirements

apply, consult your national la-

bour authorities or the manufac-

turer of the vacuum cleaner.

Transport

Before transporting the dirt

tank, close all the locks.

Do not tilt the cleaner if there is

liquid in the dirt tank.

Do not use a crane hook to lift

the cleaner.

ATTIX 791-2M/B1

Precautions and safety

regulations when using the

vacuum cleaner

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 Ser-

vice or an electrician to avoid

danger before use of the vacu-

um 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.

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

<16 A <25 A

up to 20 m

ø1.5mm² ø2.5mm²

20 to 50 m

ø2.5mm² ø4.0mm²

Use the cleaner only if it is cer-

tain that no active sources of

ignition can be sucked in.

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.

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.

It must be assured that dust not

accumulate on the appliance by

regular cleaning.

ATTIX 791-2M/B1

Use the socket on the vacuum

cleaner for the purpose defined

in the operating instructions only.

Before plugging an appliance

into the appliance socket:

1. Switch off the vacuum clean-

2. Switch off the appliance to

be connected.

CAUTION!

Follow the operating instructions

and safety instructions for appli-

ances connected to the power

tool socket.

Tool socket

Maintenance, cleaning and

repair

Only carry out maintenance

work described in the operating

instructions.

Always pull out the mains plug

before cleaning and mainte-

nance of the vacuum cleaner.

During maintenance and clean-

ing, handle the vacuum cleaner

in such a manner that there is no

danger for maintenance staff or

other persons.

In the maintenance area

– use filtered compulsory ven-

tilation

– wear protective clothing

– clean the maintenance are

so that no harmful substanc-

es get into the surroundings.

Before removing the vacuum

cleaner from the area contami-

nated with harmful substances:

– clean the outside of the vac-

uum cleaner, wipe it clean or

pack the vacuum cleaner in

well sealed packaging

– and avoid spreading depos-

ited harmful dust.

During maintenance and repair

work all contaminated parts that

could not be cleaned satisfacto-

rily must be:

– packed in well sealed bags

– disposed of in a manner that

complies with valid regula-

tions for such waste remov-

al.

A dust test must be performed

at least once every year by Nil-

fisk service or a trained person.

This test includes, for example,

whether there is damage to

the filter, the vacuum cleaner is

sealed to the air and the control

equipment works properly.

Accessories and spare parts Use only the brushes supplied

with the vacuum cleaner or

specified in the operating manu-

al. The use of other brushes can

adversely affect safety.

Use only original Nilfisk acces-

sories and spare parts (see sec-

tion 9.5). The use of other parts

can adversely affect safety.

Arrange the electrical parts

(sockets, plugs and couplings)

and lay down the extension lead

so that the protection class is

maintained.

Never spray water on to the up-

per section of the vacuum clean-

er. Danger for persons, risk or

short-circuiting.

Observe the latest edition of the

IEC regulations.

4.2.3 Suction power control The motor speed and the suc-

tion power can be varied with

the suction power control. This

allows precise adaptation of

the suction power for different

cleaning tasks.

4.3 Check volume flow

monitor

Before picking up dust with maxi-

mum room concentration values:

1. Check that all the filters,

including the filter for supply

air to the motor, are present,

properly fitted and not dam-

aged.

2. When the motor is running,

hold the suction hose shut.

An acoustic warning sounds

after approx. 1 second.

ATTIX 791-2M/B1

4.4 Acoustic warning For safety reasons, an acoustic

warning sounds if the air speed

in the suction hose drops to be-

low 20 m/s. See section “Trou-

bleshooting”.

5 Applications and techniques

5.1 Techniques If used correctly, additional ac-

cessories, suction nozzles and

suction hoses can enhance the

cleaning action and reduce the

cleaning effort.

Effective cleaning is achieved if

you follow just a few guidelines

in combination with your own

practical experience in special

fields.

Here are some basic tips.

5.1.1 Picking up dry

substances

The suction hose diameter must

suit the position of the switch in

order to pick up dry, nonflam-

mable dust with maximum room

concentration values.

There must always be a safety

filter bag in the tank before dry

substances with maximum room

concentration values are picked

up. See section 9.5 “Accesso-

ries” for ordering number.

To pick up harmless dust we

recommend the use of a waste

bag. See section 9.5 “Accesso-

ries” for ordering number. Dis-

posal of the picked up material

is then simple and hygienic.

After picking up liquids, the filter

element is wet. A damp filter el-

ement clogs more quickly when

dry substances are picked up.

For this reason the filter element

should be washed and dried or

replaced by a dry element be-

fore dry substances are picked

up.

Always use a filter bag/waste

bag that is suitable for the type

of dust (see table):

ATTIX 791-2M/B1

Type of dust Filter bag/waste bag Handling/waste disposal

• Nonhazardous coarse

dust

• Dust with MAC values

≥ 1 mg/m³

• Observe any additional

national regulations

Waste bag

No. 302001480

Waste disposal - see section 7.2.1

• Nonhazardous fine dust

• Dust with MAC values

≥1 mg/m³

• Explosive dust, explo-

sion class St1,St2,St3 in

zone 22

Filter bag

No. 302002892

Waste disposal - see section 7.2.2

Do not pick up flammable

substances.

5.1.2 Picking up liquids Always remove the filter bag/

waste bag before picking up

liquids and check that the water

level device functions properly

(see section 7.2.5, „Replacing

the filter element“).

The use of a separate filter ele-

ment or filter screen is recom-

mended.

If foam appears, stop work im-

mediately and empty the tank.

To reduce the amount of foam,

use foam killer Nilfisk Foam

Stop (see section 9.5 „Accesso-

ries“ for order number).

Do not pick up flammable

substances.

ATTIX 791-2M/B1

6 After finishing work

6.1 Switching the vacuum

cleaner off and storage

1. After picking up hazardous

dust, vacuum clean the out-

side of the cleaner.

2. Switch off the vacuum clean-

er and pull the mains plug

out of the socket.

3. Wind up the power cord and

hang it on the handle.

4. Empty the tank and clean the

vacuum cleaner.

5. After picking up liquids: Store

the upper section of the

cleaner separately so that

the filter element can dry.

6. Store the vacuum cleaner

in a dry room where it is

protected from unauthorized

use.
