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 (only for BA 551 D, BA 551 CD, BA 611 D) 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.

machine movement), to resume the operation: turn off the vacuum system by pressing the switch (73), then
open the cover (22) and check that the float inside the grid (36) has gone down to the water level. Then close
the cover (22) and turn on the vacuum system by pressing the switch (73).
When the recovery water tank (21) is full, empty it according to the following procedure.
