ENGLISH
Adjusting of detergent concentration in the washing
water
(For machines with Chemical Mixing System)
The system for mixing the detergent in the washing water is
automatically activated when the brush is running.
The percentage of detergent added to the washing water is set
to level 1 (Fig. 6).
By pressing the push-button (46), it is possible to set the
percentage level to 2, or reset it to level 0.
The set percentages are shown on the multifunction display
(48-G).
NOTE
All of the above solution flow and detergent concentration values are factory settings.
To change the settings, see the Service key paragraph, in Maintenance chapter.
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.
To start scrubbing again after a brush stop due to overload, the machine must be restarted by turning the
ignition key (41) to "O" and then 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.
