BEFORE FIRST USE
Vacuum assembly and testing
Before activating the required commands and
beginning to use the device, check that:
-
No foreign elements are present within the
container: if necessary, open the lateral closure
hooks, lift the device’s cover and remove any
such objects before use. Once the container
has been emptied, re-attach the device’ s cover
and lock its closure hooks, which guarantee an
air-tight seal;
-
The filter bag for the aspiration of MAK-dusts
has been installed: the bag is equipped with a
membrane seal which must be fitted over the
internal slot of the device’ s aspiration opening;
the bag is also equipped with an ecological
closure for its subsequent safe removal;
vaccum in category H dust it is possible with
integral filtering system applied.
-
The aspiration tube has been connected to the
aspiration opening by means of the coupling
sleeve on the tube itself.
Insert the electrical power cable’ s plug into an
electrical system outlet that is equipped with the
necessary protection devices. Activate the device using
the appropriate controls.
Initial working phase check
Before beginning to vacuum dusts with MaK values,
check that the filters fit properly within the device and
that they are positioned correctly.
Once the vacuum has been activated, block the
aspiration tube and check whether an acoustic signal
sounds: the acoustic signal turns on if the speed of the
air within the tube falls beneath 20m/sec.
In normal usage conditions, the acoustic signal turns
on to signal a reduction in pressure: the filter must be
cleaned or the bag must be replaced. .
USE OF THE DEVICE
ATTENTION!
The aspiration of flammable dusts/substances is
forbidden.
The sector’ s reference standard, E N 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.
