The manufacturer requires that the vacuum be subjected to an annual technical inspection.
This inspection may be performed by an authorised distributor’s technician and must include
the examination of the aspiration filters, the air-tight seals, as well as the signalling
DESCRIPTIVE INFORMATION
Detailed use of the machine
ATTENTION The vacuum cleaner is suitable for extracting dry non-flammable dusts, wood dusts and any
hazardous dusts with MaK values 0.1mg/m³ ( category M dust ). Based on the hazards presented by the
dusts to be aspirated, the vacuum must be equipped with appropriate filters: see the following sections.
The use of this device for the elimination of dusts must be performed in rooms or environments which
are sufficiently ventilated whenever the device’s exhaust returns into the environment itself. The user
must respect the current national regulations in the country in which the device is being employed.
The equipment’s end user must be read and understood for its use before beginning any
work activities, taking note of the safe usage regulations. The user must also receive
instruction regarding the dangers deriving from the aspirated materials and the methods for
their safe disposal.
The device’s electrical and compressed air outlets
The electrical or pneumatic outlets of the devices are to be used by single power tools that
are being used in conjunction with the vacuum cleaner.
Ensure that the power tool is correctly connected and that the power requirement is no
larger than the limitations of the vacuum cleaner.
Before connecting the power tool, ensure that the vacuum power is turned off (0 = OFF). If it
is a pneumatic system, ensure that the compressed air circuit is not pressurised, connect the
power tool and activate the compressed air connection.
Never leave the vacuum’s compressed air circuit pressurised after work activities have been
completed: close the system valve upstream from the vacuum and depressurise the
compressed air circuit.

12
For the Pneumatic System:
The device is designed to function at pressures ranging from a minimum of 4 bar to a maximum of 15 bar.
Below 4 bar, the device’s automatic start-up function is not guaranteed.
Never exceed the 15 bar pressure limit.
BEFORE FIRST USE
Before using the device, check that:
No foreign elements are present within the container.
Ensure that the head if fastened down with the head clips. This guarantees an air-tight seal.
The relevant filters and bag have been installed. The bag is equipped with a membrane seal which must
be fitted over the internal slot of the tank intake. It also has a complete orifice seal tag which must be
applied once the used bag is removed from the tank intake for safe disposal. This is important to ensure
that the contained dust does not escape.
The hose is correctly connected to the tank.
the machine is connected to the correct electrical supply.
Vacuum assembly and testing
- B) AUT – 0 – MAN switch: in the 0 position, the device is off; in the AUT position, the device turns on
automatically whenever the connected electrical or pneumatic power tool is activated; in the MAN
position, the device requires manual activation.
- A) Electrical outlet with maximum available power indicator;
- Frontal compressed air outlet for the connection of pneumatic utensils (photo 1); rear compressed
air connector for connecting the device to the compressed air system (photo 2).
The vacuum with 2 motors is equipped with the following controls:
- B) AUT – 0 – MAN switch: in the 0 position, the device is off; in the AUT position, the device turns on
automatically whenever the connected electrical or pneumatic power tool is activated; in the MAN
position, the device requires manual activation.
- A) Electrical outlet with maximum available power indicator;
- C) 0 – I activation switch for the second motor, which only starts up when the 1st motor is on
in AUT or MAN mode;
- Frontal compressed air outlet for the connection of pneumatic power tool; rear compressed air
connector for connecting the device to the compressed air system

13
Before beginning to vacuum dusts with MaK values, check that the filters fit properly within the device and
that they are positioned correctly.
Initial working phase check
Once the vacuum has been activated, block the aspiration tube and check whether an acoustic signal
sounds. The acoustic signal is activated when the speed of the air within the tube falls below 20m/sec.
This must be calibrated.
In normal usage conditions, the acoustic signal turns on to signal a reduction in pressure / air flow.
Once this sounds the filter must be cleaned and the bag must be replaced. The scientific health reason
is that dangerous dust does not remain airborne once air velocity drops below 20m/sec.
USE OF THE DEVICE
ATTENTION The aspiration of flammable dusts/substances is forbidden.
The sector’s reference standard, EN 60335-2-69/A1:2004, lists the dusts which present a risk of explosion
when brought into contact with ignition sources.
A filter bag must always be inserted into the container when the device is to be employed for vacuuming
dry substances with MaK values.
For innocuous dusts, a lower-performance paper filter bag is also available.
FILTER BAG REFERENCE TABLE:
ATTENTION
The dust collection bag must not be filled past ¾ of their capacities. Check periodically during use.
Do not vacuum liquids or particularly humid substances while the bag filters are installed.
END OF WORK ACTIVITIES
After hazardous dusts have been vacuumed, the user must open the vacuum.
Disconnect the device’s power supply by removing its electrical plug from the outlet.
Empty the container and clean the vacuum.
Store the vacuum in a safe place where it cannot be accessed by unauthorised personnel.
MAINTENANCE: FILTER REMOVAL
ATTENTION
Be careful to not stir up dusts when performing cleaning operations, filter checks or filter
replacements. Use a protective mask. Or a V-TUF filter cleaning box.
Replacing the filter bag
Undo the head clips and remove the head.
