Working with brush/pad-holder extra pressure function turned on (for Adfinity™ X20R)
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!
In case of brush/pad-holder motor overload, due to foreign bodies which prevent them from turning, or to
excessively aggressive floors/brushes, the safety system stops the motor after about one minute of continuous
overload.
The overload is shown by the three warning leds (81a, 81b, 81c) flashing 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 led (81a) stays on, the batteries allow the machine to work normally.
When the green warning led (81a) turns off, and the yellow warning led (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 led (81c) turns on, the autonomy is over. After a few seconds, the brushes/pad-holders are automatically
tuned off, while the vacuum system and (for Adfinity™ X20R) 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.
TANK EMPTYING
An automatic float shut-off system (36) stops the vacuum system when the recovery water tank (21) is full.
The vacuum system deactivation is signaled by a sudden increase in the vacuum system motor noise frequency, and the floor is not
dried.
CAUTION!
If the vacuum system turns off accidentally (for example, when the float 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 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.
Recovery water 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.
