these opera- tions are not carried out, the machine
will auto- matically deactivate the brush motor
and it will only be possible to move the machine.
In this situation if the machine is not stopped right
away, all functions will be cut off automatically,
and the machine will have to be moved by hand.
•The batteries may be irreparably damaged if the
residual charge level drops too low (see the bat-
tery operating manual). Do not force the battery
discharge beyond the safety limits, turning the key
off and on or in any other manner.
•When an abnormal situation occurs, such as
when the machine doesn't have enough power
and the safety devices don't trip, stop immedi-
ately: fol- low the instructions in the troubleshoot-
ing section and contact a specialised worker to
check the dis- charge control devices.

maintenance-free)
Remove brushes and check for brush wear, foreign bodies and
wrapped belts
Verify the machine general conditions.
Verify that suction hose and conduct are free from obstructions
Check the wear of the squeegee rubber blades
Open and clean the solution water filter
Clean the brush plate, squeegee support and squeegee

detergent solution flow as required.
The steering wheel is similar to a car steering
wheel: it can be used to turn the machine around
itself by steering all the way to one side. § Dur- ing
these operations, the rear of the machine moves
slightly outward: reduce the speed to avoid
brusque direction changes and impacts against
walls or other objects.
To avoid damage to the surfaces being treated,
the brush motor will stop automatically about 2
sec- onds after the advancement pedal has been
com- pletely released.
•Never use the machine without the detergent
solution: the floor might be damaged.
