1.5 Intended uses
These specific vacuum cleaner models have been designed, built and protected for
vacuuming dusts and solid materials only, using special filters.
Important!
__________________________________
Always use specific filters for the type of dust or materials to be vacuumed.
Any other use is considered
The vacuum cleaner is in any case intended for professional industrial use.
1.6 Allowed environmental cond
To ensure the correct operation of the vacuum cleaner, this must be positioned protected
against atmospheric agents (rain, hail, snow, fog, dusts in suspension, etc.) with an
environmental running temperature between 5°C and 45°C and relative humi

The work environment must be clean, well
1.7 Noise level
Noise level readings were taken in accordance with the provisions of
2006/42/CE standards.
Sound tests perfo
rmed on this specific vacuum cleaner model have been taken from a
distance of 1 meter and from a height of 1,60 meters, showing an acoustic pressure no
higher than:
The vibrations transmitted by the machine are lower than 2,5 m
Important!
Pursuant to articles L.D. 81/08, workers exposed to sound pressure levels above 85
dB(A)
must be protected by special individual protection devices.
It is therefore necessary, i
such approved individual protection devices and to inform them of the risks relating
to noise exposure.
1.8 Storage
Remove the filter and clean it, empty the container and store the vacuu
protected against atmospheric agents with a temperature between 0°C and 40°C. Cover
with a nylon sheet to prevent accumulation of dust.
1.9 Scrapping
In case of scrapping, all the component parts of the vacuum cleaner will have to
disposed of through adequate disposal channels in accordance with applicable legislation.
Before scrapping, all plastic and rubber parts will have to be separated from the electrical
material. Parts made of plastic, aluminium and steel only may be recyc
special centres.

______________________________________________________________
The following indications are, by themselves, not enough to fully protect against all
the hazards that could arise during vacuum cleaner operation. These will have to be
integrated with common sense and the experience of the operator, both of which are
c
rucial factors for preventing accidents. Each section of this manual lists further
specific safety precautions for the various operations.
Maintenance jobs must always be performed with the power plug detached from the

During cleaning operations, maintenance jobs or when changing parts, the starter switch
must be off and the machine must be disconnected from the power mains by removing the
cable from the socket. Only skilled persons should carry out repairs.
During use, mind the power supply cables and avoid crushing or pulling these. Periodically
check the mains power cable to ensure this is not damaged.
