Working with brush/pad-holder extra pressure function turned on
If the
fl
oor proves to be particularly dif
fi
cult 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.
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 motor 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 (11c), press the pedal to position (11b). If the
overload persists, the brush/pad-holder stops.
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 brush/pad-holder is automatically tuned
off, while the vacuum system and (only for
BA 551D
,
BA 551CD
,
BA 611D
) the drive system stay on, to
fi
nish drying the
fl
oor 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.
TANK EMPTYING
An automatic
fl
oat shut-off system (36) turns off the vacuum system when the recovery tank (21) is full.
The vacuum system deactivation is signalled by a sudden increase in the vacuum system motor noise frequency, and the
fl
oor is
not dried.
CAUTION!
If the vacuum system turns off accidentally (for example, when the
fl
oat is activated because of a sudden
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
fl
oat 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 tank (21) is full, empty it according to the following procedure.
Recovery tank emptying
Stop the machine.
1.
Lift the brush/pad-holder deck by pressing the pedal (11).
2.
Lift the squeegee (25) with the lever (10).
3.
Drive the machine to the appointed disposal area.
4.
Empty the recovery tank with the hose (16). Then, rinse the tank with clean water.
5.
Solution/clean water tank emptying
Perform steps 1 to 4.
6.
Empty the solution tank with the hose (17). Then, rinse the tank with clean water.
7.
Cylindrical brush debris container emptying (only for cylindrical brush deck)
Stop the machine.
8.
Lower the cylindrical brush deck and remove the debris container (D, Fig. 3) by pulling it on one side with the handle (E).
9.
Empty and wash the debris container (D), and then install it by engaging it on the fasteners.
