Setting to work - connection to the power supply
ATTENTION DANGER!
– Make sure that the vacuum cleaner is in perfect
condition before commencing work.
– Before plugging the vacuum cleaner into the electricity
mains, make sure that the voltage rating indicated on
the data plate corresponds to that of the electricity
mains.
– Plug the vacuum into a socket with a correctly
installed ground contact/connection. Make sure that
the vacuum cleaner is off.
– The plugs and connectors of the connection cables
must be protected against water splashes.
– Make sure that connections to the electricity main and
plug are correct.
– Only use vacuum cleaners when the cables that
connect to the electricity main are in perfect
conditions (damaged cables could lead to electric
shocks!).
– Regularly check that the electric cable does not show
signs of damage excessive wear, cracks or ageing.
ATTENTION DANGER!
When the vacuum cleaner is operating, do not:
– Crush, pull, damage or tread on the flex that connects
to the electricity main.
– Only disconnect the flex from the electricity main by
removing the plug (do not pull the flex).
– Only replace the electric power cable with one of the
same type as the original: HO7 RN-F. The same rule
applies if an extension is used.
– The flex must be replaced by the manufacturer's
Assistance Service staff or by an equivalent qualified
personnel.

Extensions
If an extension is used, make sure it is fit for the power draw
and protection degree of the vacuum cleaner.
ATTENTION DANGER!
Variant B1: extensions, plugged-in electrical devices and
adapters cannot be used when the vacuum cleaner is used
for flammable dusts.
Minimum section of extension cables L = 20 m max
Cable = HO7 RN - F.

ATTENTION DANGER!
Sockets, plugs, connectors and installation of the
extension cable must maintain the IP protection degree of
the vacuum cleaner, as indicated on the data plate.
ATTENTION DANGER!
The vacuum cleaner's power socket must be protected by
a differential circuit-breaker with surge current limitation,
that shuts off the power supply when the current dispersed
towards ground exceeds 30 mA for 30 ms or an equivalent
protection circuit.
ATTENTION DANGER!
Never spray water on the vacuum cleaner: such action
constitutes a danger hazard for persons and could
shortcircuit the power supply.
Consult the latest edition of the European Union Directives,
the Laws in the country of use and the current standards
in force (UNI - CEI - EN), particularly European standard
EN60335-2-69.
