“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 ashing 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 ashing 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 nish drying the oor 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.
