Hazardous marking explanation

These vacuum cleaners are certified by an NRTL to operate
in a ClassII Div2 area where dusts belonging to Group F, G
are present. These are marked as follows:
ClassII Div2: is an hazardous area
(1) In which combustible dust due to abnormal operations
may be present in the air in quantities sufficient to produce
explosive or ignitable mixtures; or
(2) Where combustible dust accumulations are present but
are normally insufficient to interfere with the normal operation
of electrical equipment or other apparatus, but could as a
result of infrequent malfunctioning of handling or processing
equipment become suspended in the air, or
(3) In which combustible dust accumulation on, in or in
the vicinity of the electrical equipment could be sufficient
to interfere with the safe dissipation of heat from electrical
equipment or could be ignitable by abnormal operation or
failure of electrical equipment.
Group F, G: Atmospheres containing but not limited to:
carbon, black coal, coke dust, flour starch or grain dust.
T4A: the maximum surface temperature measured on the
vacuum cleaner at the maximum ambient temperature is 120°C.
Setting to work - connection to the power
supply
WARNING!
■ Make sure there is no evident sign of damage to
the vacuum cleaner before starting work.
■ Before plugging the vacuum cleaner into the
electrical mains, make sure the voltage rating
indicated on the data plate corresponds to that of
the electrical mains.
■ Plug the vacuum cleaner into a socket with a
correctly installed ground contact/connection.
Make sure that the vacuum cleaner is turned off.
■ The plugs and connectors of the connection cables
must be protected against splashes of water.
■ Check that for proper connection to the electrical
US
mains.
■ Use the vacuum cleaners only when the cables
that connect to the electrical mains are in perfect
condition (damaged cables could lead to electric
shocks!).
■ Regularly check there are no signs of damage,
excessive wear, cracks or aging on the electric
cable.
WARNING!
When the vacuum cleaner is operating, do not:
■ Crush, pull, damage or tread on the cable that
connects to the electrical mains.
■ Only disconnect the cable from the electrical mains
by removing the plug (do not pull the cable).
■ Only replace the electric power cable with one of
the same type as the original: S00W. The same rule
applies if an extension is used.
■ The cable must be replaced by the manufacturer's
Service Center staff or by equivalent qualified
personnel.

material, do not attempt to on its contents without personal
protective clothing and respiratory protection

Extensions

If an extension cable is used, make sure it is suitable for the
power input and protection degree of the vacuum cleaner. and
for hazardous area ClassII DIV2 Group F and G.
WARNING!
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 discharged to the ground exceeds 30 mA for
30 ms or an equivalent protection circuit.
WARNING!
Never spray water on the vacuum cleaner: this could
be dangerous for persons exposed and could short
circuit the power supply.

Wet and dry applications

[ NOTE ]
The supplied filters and the bag (if applicable) must be
installed correctly.
WARNING!
Comply with the safety regulations governing the
materials for which the vacuum cleaner is used.
WARNING!
If the version for liquids is used:
■ Make sure the liquid shut-off device is working
correctly before vacuuming liquids.
■ If foam forms, turn off the vacuum cleaner
immediately and empty the container.
■ Warning: Switch off the vacuum cleaner
immediately if foam or liquid leaks out.
■ Regularly clean the liquid shut-off device and check
to make sure that there are no signs of damage.
■ Warning: Dirty liquid vacuumed up by the vacuum
cleaner must be considered conductive.
WARNING!
When vacuuming a mix of water and air, take care to avoid
overloading the motor of the vacuum unit.

Maintenance and repairs

WARNING!
Disconnect the vacuum cleaner from its power
source before cleaning, servicing, replacing parts or
converting it to obtain another version/variant, the
plug must be removed from the socket.
■ Carry out only the maintenance operations
described in this manual.
■ Use only original spare parts.
■ Do not modify the vacuum cleaner in any way.
Failure to comply with these instructions could
