BEFORE MACHINE START-UP
DECK INSTALLATION/REPLACEMENT
On the machines from Serial Number 1776829, it is possible
to install either a brush-holder/pad-holder deck (12, Fig. C) or
a cylindrical brush-holder deck (15).
For deck installation/replacement see the procedure in the
Maintenance chapter.
Brush or pad-holder installation/replacement
1. According to the kind of cleaning to be carried out, the
machine can be equipped both with brushes (15, Fig. J)
and pad-holders (16) with pads(17) together with the
appropriate deck.
2. Insert the ignition key (10, Fig. B) and turn it to “I”
position.
3. Idle the speed adjuster (7, Fig. B) by turning it
counter-clockwise.
4. Position the brushes/pad-holders under the appropriate
deck (12, Fig. C).
5. Press the switch (2, Fig. B) to lower the deck (12, Fig. C).
6. Lightly press the paddle (4, Fig. C) to engage the

Fig. C) (lifted position).
8. Turn the ignition key (10, Fig. B) to “0” position and
remove it.
Cylindrical brush installation
9. Insert the ignition key (10, Fig. B) and turn it to “I”
position.
10. Turn on the cylindrical brush-holder deck lifting/lowering
switch (2, Fig. B).
11. Turn the ignition key (10, Fig. B) to “0” position and
remove it.
12. Unscrew the handwheels (25, Fig. J) and remove the
lids (24) by pushing them downwards and pressing on
the handwheels.
13. Install the cylindrical brushes (23).
The cylindrical brushes can be installed on either sides.
14. Reinstall the lids (24, Fig. J) and fix them with the
handwheels (25).
Squeegee installation
15. Install the squeegee (16, Fig. C) and fix it by means of
the handwheels (17), then connect the hose (24) to the
squeegee.
16. Using the handwheel (18, Fig. C), adjust the squeegee
so that its rear blade (20) - in all its length - touches the
floor and that the front blade (19) is slightly detached
from the floor.
Solution tank filling
17. Open the tank cover (1, Fig. G).
18. Lift the shield (15, Fig. G) and, by means of the
extractible hose (6), fill the solution tank (4) with the
appropriate solution for the cleaning to be carried out.
Do not fill the solution tank completely, leave a few
centimeters from the edge.
Always follow the dilution instructions on the label of the
chemical product used to create the solution.
The solution temperature must not exceed 104°F
(40°C).
Using the transparent hose (1, Fig. J) and the marks (2),
it is possible to check the quantity of solution in the tank.
Moreover, it is possible to consult a gallon/liter table
located on the inner side of the cover (1, Fig. G).
Adjustments
19. Using the knobs (3, Fig. C), adjust the handlebar (2) to

WARNING!
When the machine is to be started by turning
the ignition key (10, Fig. B) to “I” position,
makesurethat,betweenthedeck(12or15,Fig.
C) and the above tank assembly, there is no
foreign material which may prevent the deck
from lifting. This check is necessary because,
if the machine has been previously turned off
without the deck being deactivated (lifted
position), when turned on again, the deck is
automatically deactivated (lifted position).
WARNING!
Before turning on the brush/pad-holder deck
lifting/lowering switch (2, Fig. B), always check
that, between the deck (12) and the above tank
assembly, there is no foreign material which
may prevent the deck from lifting.
WARNING!
Do not press the paddle (4, Fig. C) completely,
otherwise the machine will start; a light
pressure on the paddle is enough to engage
the brushes and activate the brush motors.
WARNING!
When the deck has not been lifted yet, and the
warning light on the switch (2, Fig. B) is
flashing, the brushes (11, Fig. C) start to turn
when pressing the paddle (4, Fig. C). It is
therefore important to make sure that there is
nothing which can prevent the brush from
rotating and that nobody is near the brushes
before pressing the paddle (4, Fig. C).
WARNING!
Before turning on the cylindrical brush-holder
deck lifting/lowering switch (2, Fig. B), always
check that, between the deck (15) and the
above tank assembly, there is no foreign
material which may prevent the deck from
lifting.

Brush overload safety system activation
7. In case of brush motor overload, due to foreign bodies
which prevent the brushes/pad-holders from rotating, or
to excessively aggressive floors/brushes, the safety
system stops the brushes/pad-holders after about a
minute of continuous overload. The overload is shown
by the three warning lights (9a, 9b, 9c, Fig. B) flashing
simultaneously.
If the overload takes place during a cleaning with the
extra pressure function activated, the system
automatically reduces the pressure on the
brushes/pad-holders deactivating the extra pressure
function. If the overload persists, the
brushes/pad-holders stop.
8. To start again after the brushes/pad-holders stop due to
overload, reset the machine by turning the ignition key
(10, Fig. B) to “0” position; then restart the machine by
turning the ignition key to “I” position.
Battery discharge during operation
9. Until the green warning light (9a, Fig. B) stays on, the
batteries allow the machine to work normally.
When the green warning light (9a) turns off and first the
yellow warning light (9b) and then the red warning light
(9c) turn on, it is necessary to charge the battery,
because the machine residual autonomy of operation is
the following:
– When the yellow warning light (9b) turns on the
machine residual autonomy will last for a few
minutes (depending on the characteristics of the
battery).
– Whenthered warning light (9c)turnson the machine
autonomy is over: after a few seconds
brushes/pad-holders are automatically stopped and
the deck is automatically lifted; the squeegee
vacuumingandthemachinedrivestilloperate,justto
dry the wet floor and move the machine to the
charging area.
Recovery water recirculation function (optional)
10. If equipped, turn the switch (35, Fig. C) to “I” position to
activate the recovery water recirculation function.
This function allows the recovery water collected in the
tank (5, Fig. G), once it has been adequately
regenerated by passing through the filter (8, Fig. G), to
be used together with the clean solution in the tank (4,
Fig. G).
11. If equipped, turn the switch (35, Fig. C) to “0” position to
deactivate the recovery water recirculation function. The
machine restarts to operate normally, using only the
clean solution in the tank (4, Fig. G).
TANK EMPTYING
An automatic float shut-off system (7, Fig. G) deactivates the
vacuum system once the recovery tank (5) is full.
The vacuum system deactivation is signalled by a sudden
increase in the vacuum motor noise frequency. The vacuum
motor stops automatically after a few seconds.
When the recovery water tank (5, Fig. G) is full, empty it
according to the following procedure.
CAUTION!
Do not use the machine with discharged
batteries, to avoid damaging the batteries and
reducing the battery life.
NOTE
In case the machine drive cannot be used in
order to move the machine, see the
Pushing/Towing The Machine paragraph.
CAUTION!

The recovery water recirculation function can
be very useful when cleaning industrial areas,
etc.
NOTE
The recovery water recirculation function
switch (35, Fig. C) can be activated and
deactivated in any moment, but note that the
recovery water recirculation system starts
operating only when the tank (5, Fig. G)
contains at least 60 liters of water (tank filled
up to 3/4).
CAUTION!
If the vacuum motor stops accidentally (for
example, because of the float interference due
to a sudden movement of the machine), to
restart the vacuum system, lift the squeegee
(16, Fig. C) by means of the lever (25) and then
lower it.
