PRELIMINARY OPERATIONS
Disconnect the locks on both sides of the tank
lid.
Fill the tank with detergent and water, making a
mix in accordance with the instructions of the
detergent manufacturer.
Close the tank lid.
Warning: do not use flammable nor explosive
solutions; foam making detergents are not
allowed.
Insert the ignition key into the panel and turn it
clockwise: the display will show four zeros and
after a few seconds the battery voltage will
appear.
Note: wait minimum 5 seconds to switch On the
machine after having switched it Off; otherwise
you will not get the start.
Check the battery voltage on the display.
The display has three functions: voltmeter, brush
pressure indicator and hour meter. The voltmeter
will activate the block function during an
undervoltage; it will disable all the machine
activities - except for the drive - when the battery
voltage drops below 29 Volt (the display flashes):
in this case the recharge of the battery must be
done as specified in the Maintenance paragraph
(see also the battery user manual).
