AUTOMATIC “MOTOR PROTECTOR”
In the event of certain conditions existing which could overload the electric
motor (foreign bodies in the brushes that could block their rotation, power
supply fluctuations, overheating etc.), the “Motor Protector” will intervene
and stop the machine.
Important: Disconnect the machine from
the power point before removing any
foreign bodies caught up in the brushes.
After waiting for approximately 60 seconds,
restore the machine operation by pressing
the same “Motor Protector” button.
CLEANING AND MAINTENANCE OF THE BRUSHES
Remove the plug from the power point before proceeding with the cleaning
or maintenance operations or replacement of the brushes.
The DUPLEX brushes do not require anything more than periodic
maintenance seeing that their high speed rotation is capable of centrifuging
the dirt and always keep them efficient.
Every now and then it will be necessary to remove the brushes and soak them
for several hours in a basin filled with cold or warm (never hot) water, in
which the same detergent used for cleaning the floors must be added.
After having washed and rinsed the brushes well, their bristles will regain in
vigour and elasticity.
At the moment of reassembling the brushes it is important to remember to
invert them. This precaution is necessary due to the fact that if they always
rotate in the same direction the bristles may tend to bend.
