3.0IMPORTANT SAFETY PRECAUTIONS
3.1.MOTOR COOLING AIR INTAKE
WARNING: DO NOT WRAP THE ELECTRIC CABLE AROUND THE
MOTOR COOLING AIR INTAKE OR OBSTRUCT THE
MOTOR COOLING AIR INTAKE IN ANY WAY DURING
OPERATION. THIS WOULD PREVENT AIR TO COOL DOWN
THE MOTOR, THE TEMPERATURE OF THE MOTOR
WOULD RISE, AND THIS WOULD STOP THE VACUUM
CLEANER.

Motor cooling air intake must
remain unobstructed at all
times during operation

3.2.FILTER BLOCKAGE WARNING LIGHT
A filter blockage warning light is installed on the vacuum cleaner. The light turns on to
indicate a loss of suction. In such case the collection bag may be full, cloth filters (main
filters and safety filters) may need to be washed or HEPA filters may need to be replaced.
WARNING: When the filter blockage warning light turns on, turn the vacuum
cleaner off as soon as possible as filter blockage cause the
temperature inside the vacuum cleaner to rise and can also lead to
motor damage.
For maintenance refer to “Cleaning and maintenance” and to “Assembling and replacing the
HEPA filters” sections.
3.3.LAYERS OF DUST
WARNING: Clean regularly the vacuum cleaner surfaces with a water damped
cloth to avoid dust accumulation which could create a potential source
of ignition.
3.4.BURNING MATERIAL
WARNING: DO NOT PICK-UP ANYTHING THAT IS BURNING OR SMOKING, SUCH
AS HOT ASHES, CIGARETTES, MATCHES OR LIVE EMBERS.
3.5.FLAMMABLE LIQUIDS
WARNING: THIS VACUUM CLEANER IS NOT DESIGNED TO RECOVER
FLAMMABLE LIQUIDS. DO NOT USE THIS VACUUM CLEANER TO
RECOVER FLAMMABLE LIQUIDS.

3.6.SELF-IGNITION OF DUST
WARNING: DO NOT USE THIS VACUUM CLEANER TO RECOVER DUST OR
MIXTURE OF DUSTS THAT CAN SELF-IGNITE.
3.7.MECHANICALLY GENERATED SPARKS
WARNING: To prevent mechanically generated sparks (thermite reaction) avoid
impact of the wand and tools supplied with the vacuum cleaner with
any rusted parts present in the working area.
3.8.IMPORTANT SAFETY PRECAUTIONS IN REGARD TO ELECTROSTATIC
CHARGES GENERATION
When the vacuum cleaner is used as recommended in this manual it has been determined
that no significant or continuous electrostatic charge accumulation, which could act as a
potential ignition source, can occur.
Nevertheless, it is recommended for safe use not to perform any specific action on the
insulating items assembled on the vacuum cleaner, such as a continuous and intense
manual rubbing, which could lead to a significant electrostatic charge accumulation.
The above instructions are to be observed particularly in regard to the plastic wheel covers
on the vacuum cleaner.
