Setting The Cleaning Controls; Brush Overload (Over Current) - Numatic ETB 1120 Mode D'emploi

STAND-BY
Stage 1.
Stage 2.
Stage 3.
When the triggers are released the brush motor and the cleaning solution pump will switch off, the vacuum motor will
continue for 10 seconds (this is to clear any fluid residue in the hose).
The panel if unused will automatically enter SLEEP MODE after 60 seconds.
If the brush motor keeps overloading consider using a different type of brush.
Or move the transit wheels to obtain different brush pressures,
Heavy brush load decreases the available battery run time.
The ETB has been fitted with a Hi - Lo mode, this reduces the noise produced by the
vacuum motor by 3dB.
To operate the Hi - Lo mode start the machine in the normal way.
When the machine is running normally the Hi Lo light will be illuminated blue, this means the
Vacuum motor is running at 100%.
With the machine running press the Hi Lo button once the Vacuum motor will reduce speed
to 75% of capacity and the Hi lo light will not illuminate.
