ENGLISH
Adjusting of detergent concentration in the washing
water
(For machines with EcoFlex 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 display (51-G).
EcoFlex System
Use the EcoFlex lever (50) when a temporary stronger washing power is needed.
With the EcoFlex system activated, increased solution flow, activation of the extra pressure of the brush and an increase in the
solution detergent concentration (level 2 if the level was set to 1 - level 1 if the level was set to 0) is obtained.
By using the EcoFlex lever (50) again, the original settings are restored.
NOTE
If the lever (D) is not used once again, the original settings are restored automatically after 60 seconds.
NOTE
All of the above solution flow and detergent concentration values are factory settings.
To change these settings, see the Supervisor key paragraph in Maintenance chapter.
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 One-Touch push-button (43) to lower the brush deck as shown in "Starting The Machine" paragraph.
2. Press and hold the One-Touch push-button (43) 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 One-Touch push-button (43) for more than 1 second.
4. To lift the brush deck without returning to the normal pressure, press the One-Touch push-button (43) 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, turn off and then on the machine with the push-
button (42).
Battery discharge during operation
When there is only one segment turned on and flashing on the battery symbol (51-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 (51-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.
