To avoid overload of the brush motor, reduce the
brush pressure when going from smooth floors to
rough ones (ex. concrete).
ELECTRIC PROTECTION
The machine is equipped with an electronic system
of protection for all components that carry out
functions of power or control. This device blocks the
defective component and indicates on the display (1)
the corresponding alarm from”AL01” to “AL20”.
ATTENTION:
To restore the function of the component, turn off
the machine and restart it using the key switch. If
the problem persists, please contact an
authorized technical assistant.
OVERFLOW DEVICE

When this happens, empty the recovery tank (see
“RECOVERY TANK EMPTYING AND
CLEANING”).
