Brush motor overload protection electronic system
This system works when the brush motor is overloa-
ded.
Its operation is signaled by the three warning lights
flashing at the same time (2, 3, 4, Fig. B); after a few se-
conds, the brush motor stops.
In order to restart the motor, it is necessary to eliminate
the cause of the overload, which can be:
– the brush is too much pressed on the floor
– the brush is blocked by floor roughness or by a
foreign body
– the brush rotation is slowed down by dirt, ropes or
rags around its rotation shaft
– the friction between brush and floor is excessive
(increase the detergent quantity by means of the
appropriate adjusting lever (7, Fig. B))
Once the overload cause has been eliminated, reset
the system as indicated here below:
– (20B versions) stop the machine by turning switches
(5 and 6, Fig. B) to "0".
– (20BT versions) stop the machine by turning the
ignition key (9, Fig. B) to "0".
After that, the machine can be restarted again, as de-
scribed in the related chapter.
Drive motor overload protection electronic system
(20BT versions only)
This system works when the drive motor is overloaded.
Its operation is signalled by the drive motor stopping.
After a while, the system can be reset by stopping the
machine by turning the ignition key (9, Fig. B) to "0".
After that, the machine can be restarted again, as de-
scribed in the related chapter.
ACCESSORIES / OPTIONS
In addition to the standard components, the machine
can be equipped with the following accessories/op-
tions, according the machine specific use:
1. Gel batteries.
2. Brush of materials different from the standard
ones.
