Warning!
Before turning the vacuum on again, ensure that the pump has fully stopped.
Attention!
If dust escapes from the head of the vacuum (for the Mini Bull) or from the silencer (for
TB) the filter may be broken.
In this case, stop the vacuum immediately and verify the
cause.
To move the vacuum use the special grip on the rear part.
Warning!
During operation, prevent the hose from rolling up or bending.
The red indicator light (number) on the Mini BULL vacuum indicates filter clogging.
A vacuum gauge is
installed on TB models indicating the level of negative pressure inside the vacuum.
The
vacuum gauge indicates the condition of the filter: negative pressure increases indicate filter clogging, with
consequent reduction of the suction power.
When the filter is clogged, the vacuum meter indicates the value shown in the table below.
Model
Clogged filter value
Mini BULL
- 0.16 bar
- 16 kPa
TB 15
- 0.16 bar
- 16 kPa
TB 22
- 0.16 bar
- 16 kPa
TB 22/22 (*)
- 0.18 bar
- 18 kPa
(*) valid values for all models with optional HEPA filter.
In the event that the red indicator light turns on or the negative pressure is higher than that reported
in the table, check firstly that the hose and/or the suction accessory is not clogged. In this case,
remove the cause of the clog. Otherwise it will be necessary to clean the filter as described below:
- turn off the machine
- wait for the rotating motors to come to a complete stop
