Working with brush extra pressure function turned on
If the floor proves to be particularly difficult to clean, it is possible to turn on the brush extra pressure function, according to the
following procedure:
1. Press the push-button (42) to lower the brush deck as shown in "Starting The Machine" paragraph.
2. Press and hold the push-button (42) for more than 1 second. The extra pressure function activation is shown by LED which
turns from green to red, and by the icon
3. To return to normal pressure, press and hold the push-button (42) for more than 1 second.
4. To lift the brush deck without returning to the normal pressure, press the push-button (42) and release it immediately.
CAUTION!
In case of brush motor overload, due to foreign bodies which prevent them from turning, or to excessively
aggressive floors/brushes, the safety system stops the brush after about one minute of continuous overload.
If the overload takes place when the extra pressure function is on, the system automatically turns the extra
pressure function off.
If the overload persists, the brush stops.
To start scrubbing again after a brush stop due to overload, stop the machine by turning the ignition key (41) to
"0". Turn on the machine by turning the ignition key (41) to "I".
Battery discharge during operation
When there is only one segment turned on and flashing on the battery symbol (48-C), it is advisable to charge the batteries,
because the residual autonomy will last for a few minutes (depending on battery characteristics and work to be performed).
When the battery symbol (48-C) is flashing and no segment is turned on, the battery autonomy is over. After a few seconds, the
brush is automatically tuned off, while the vacuum system and the drive system stay on, to finish drying the floor and drive the
machine to the appointed recharging area.
CAUTION!
Do not use the machine with discharged batteries, to avoid damaging the batteries and reducing the battery life.
NOTE
In case the machine drive system cannot be used in order to move the machine, see Pushing/Towing The Machine
paragraph.
