4. Press and hold the flow control switch (A) until the warning light (B) flashes.
5. Release the switch (A). Press it again shortly, to go to the next percentage shown by the indicator (C); repeat the
procedure until the desired setting is reached.

Working with brush/pad-holder extra pressure function turned on
7. If the floor proves to be particularly difficult to clean, it is possible to turn on the brush/pad-holder extra pressure function
by pressing the pedal (11) to position (11c).
CAUTION!
When the cylindrical brush deck (18c) is installed, the extra pressure function is not enabled.
Battery discharge during operation
8. Until the green warning light (81a) stays on, the batteries allow the machine to work normally.
When the green warning light (81a) turns off, and the yellow warning light (81b) turns on, 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 red warning light (81c) turns on, the autonomy is over. After a few seconds, the brushes/pad-holders are
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.
