1 Important safety instructions
Symbols used to mark
instructions
For your own safety
Before using the
vacuum cleaner,
always read the
operating instructions and keep
them readily
available.
This symbol is
used to mark
safety instructions that must
be observed to
prevent damage to persons.
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.
This symbol is
used to mark
safety instructions that must
be observed to
prevent damage
to the vacuum cleaner and its
performance.
This symbol indicates tips and
instructions to
simplify work and to ensure safe
operation.
The use of the vacuum cleaner
is subject to valid national regulations. Besides the operating
instructions and the binding
accident prevention regulations
valid in the country of use, observe recognized regulations for
safety and proper use.
Do not use any unsafe work
techniques.
Transport
Purpose and intended use
Before transporting the dirt
tank, close all the locks.
Do not tilt the cleaner if there is
liquid in the dirt tank.
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-
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 magnesium additional requirements
apply, consult your national labour authorities or the manufacturer of the vacuum cleaner.

ATTIX 791-2M/B1
Precautions and safety
regulations when using the
vacuum cleaner
Use the cleaner only if it is certain that no active sources of
ignition can be sucked in.
Conductive extraction equipment, 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 electrostatic charges.
The cleaner is not suitable for
extraction on machining equipment in operation that could
produce sources of ignition.
When dust removers are used,
Before start-up
Inspect power cord regularly
to detect signs of damage, e.g.
cracks or ageing.
the rate at which air is exchanged in the room must be
adequate if the exhaust air from
the vacuum cleaner is blown into
the room (please observe regulations valid in your country).
Before starting work, the operating 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.
limits the water level and check
it for damage.
See section 5 for information on
handling liquids and (hazardous) dust.
If the power cord is damaged,
it must be replaced by NilfiskAlto-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
Electrical components
Check the rated voltage of the
vacuum cleaner before connecting it to the mains supply
system. Ensure that the voltage
shown on the rating plate corresponds 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 connected via a residual current
circuit breaker. This stops the
supply of electricity if the leakage 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-sections of the cable:

Tool socket
Maintenance, cleaning and
repair
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 upper section of the vacuum cleaner. Danger for persons, risk or
short-circuiting.
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 cleaner
2. Switch off the appliance to
be connected.
Only carry out maintenance
work described in the operating
instructions.
Always pull out the mains plug
before cleaning and maintenance of the vacuum cleaner.
During maintenance and cleaning, 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 substances get into the surroundings.
Before removing the vacuum
cleaner from the area contaminated with harmful substances:
Observe the latest edition of the
IEC regulations.
CAUTION!
Follow the operating instructions
and safety instructions for appliances connected to the power
tool socket.
– 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 satisfactorily must be:
– packed in well sealed bags
– disposed of in a manner that
complies with valid regulations for such waste removal.
A dust test must be performed at
least once every year by NilfiskAlto 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 manual. The use of other brushes can
Use only original Nilfisk-Alto accessories and spare parts (see
section 9.5). The use of other
parts can adversely affect safety.

4.4 Acoustic warning
For safety reasons, an acoustic
warning sounds if the air speed
in the suction hose drops to below 20 m/s. See section “Troubleshooting”.
5 Applications and techniques
5.1 Techniques
If used correctly, additional accessories, 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

substances.
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 “Accessories” for ordering number.
After picking up liquids, the filter
element is wet. A damp filter element 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 before dry substances are picked
up.
To pick up harmless dust we
recommend the use of a waste
bag. See section 9.5 “Accessories” for ordering number. Dis-
Always use a filter bag/waste
bag that is suitable for the type
of dust (see table):
Type of dustFilter bag/waste bagHandling/waste disposal
• Nonhazardous coarse
dust
• Dust with MAC values
≥ 1 mg/m³
• Observe any additional
national regulations
• Nonhazardous fine dust
• Dust with MAC values
