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-
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.
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
m
Cross section
<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.
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.
