venient to reduce the brushes pressure going from
smooth floors to rough ones (ex. concrete)
.
BRUSHES MOTOR OVERLOAD PROTECTION DE-
VICE
The machine is equipped with a protection device of
the brushes motor. This device blocks the motor
functioning in order to protect it and indicates the
overload on the display (1) with ”AL01”. The block
could be caused by an excessive brushes pressure on
a rough floor. Check the brushes pressure adjust-
ment as indicated in the previous paragraph.

To restore the functioning of the brushes motor,
turn off and on again the machine acting upon
the key switch (9).

covery tank.
1. Hold the exhaust hose placed in the front part of
the machine.
