ENGLISH
Working with brush/pad-holder extra pressure function turned on (only for BA 651, BA 751, BA 851)
If the fl oor proves to be particularly diffi cult to clean, it is possible to turn on the brush/pad-holder extra pressure function, according
to the following procedure:
1. Press the switch (71) to lower the brush/pad-holder deck as shown in Starting The Machine paragraph.
2. Press and hold the switch (71) for more than 1 second. The extra pressure function activation is shown by the warning light
(72) which turns from green to red.
To return to normal pressure, press and hold the switch (71) for more than 1 second.
To lift the brush/pad-holder deck without returning to the normal pressure, press the switch (71) and release it immediately.
CAUTION!
In case of brush/pad-holder motor overload, due to foreign bodies which prevent them from turning, or to
excessively aggressive fl oors/brushes, the safety system stops the brushes/pad-holders after about one minute
of continuous overload.
The overload is shown by the three warning lights (81a, 81b, 81c) fl ashing simultaneously.
If the overload takes place when the extra pressure function is on, the system automatically reduces the
pressure on the brushes/pad-holders, thus turning the extra pressure function off.
If the overload persists, the brushes/pad-holders stop.
To start scrubbing again after a brush/pad-holder stop due to overload, stop the machine by turning the ignition
key (80) to "0". Turn on the machine by turning the ignition key (80) to "I".
Battery discharge during operation
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 automatically stop;
only vacuum and drive systems still operate, just to dry the wet fl oor and move the machine to the appointed charging area.
CAUTION!
Do not use the machine with discharged batteries, to avoid damaging the batteries and reducing the battery life.
