suitable packing.
The total weight is 165lbs.
Packing dimensions:
Base: 30 in x 16 in
Height: 24.5 in.
ATTENTION:
Do not place more than two
machine packages on top of
each other.
Unpacking the machine
1. Open the packing as shown
in the figure.
2. Carefully take the machine
off the packaging.
3. Keep packaging for future
transport needs.
Movement of the handle bar
The handle bar in the package
arrives in the closed position.
To rotate the handle bar in
one of the different working
positions to move the
machine:
1. Pull up the release lever (8)
near the handle bar.
2. Rotate the handle bar into
the working position while
holding the release lever (8).
3. Release the release lever (8)
to lock the handle bar.
Use the same procedure for
further height adjustment of
the handle bar to find the
most comfortable working

Battery
This machine is supplied
with two batteries already
connected in series, placed in
its appropriate compartment
under the recovery tank.
In case the batteries need
to be disassembled and/
or replaced, please contact
the authorized technical
assistance.
In fact, the replacement must
be made exclusively with
batteries which have the
identical performances as the
ones already installed.
To reach the battery
compartment it is necessary
to:
1. Remove the squeegee hose
from its seat (17).
2. Remove the suction filter
cover (19) after turning the
blocking levers (18).
3. Lift and remove the recovery
tank (16) holding it from the
provided handles. One on the
front and one on the rear of
the tank
ATTENTION:
Strictly follow manufacturer/
distributor indications for
the maintenance and daily
recharge of the batteries.
Specialized staff, using
suitable protection
accessories must execute all
installation and maintenance
operations.
Battery recharging
(Standard version with AGM
batteries) The charge level of
the battery is visible by first
activating the main switch (1)
placed on the instrument
board, through three luminous
LEDs placed on the frame in
the rear part of the machine.
A: green LED on = batteries
are charged.
B: orange LED on = level at
half charge.
C: red LED on = complete
discharge of the batteries with
consequent automatic
switching off of all the
machine's function.

9
To prevent permanent damage
to the batteries, it is essential
to completely discharge
every 6 or 7 cycles, providing
for the recharge only when
the red signal of discharged
batteries is activated. In fact,
an extended series of charging
cycles carried out when the
batteries still have a residual
charge, causes a battery to
deteriorate, shortening the
battery life.
NOTE: Never leave batteries
completely discharged even if
the machine is not used.
During the recharging
operation a device is activated
that restricts the machine from
functioning.
Bring the machine on a level
surface near a suitable outlet.
Switch off the main switch (1).
Connect the main cable
supplied with the machine
both to the machine (22)
and to the outlet socket as
indicated in the figure. At the
end of the charging phase take
off the main cable.
Battery disposal
It is mandatory to hand over
exhausted batteries, classified
as dangerous waste, to
an authorized institution
according to the local laws.
Recovery tank
Check that the cover of the
vacuum filter (19) is correctly
secured, after rotating the
levers (18). Furthermore, check
that the squeegee hose is
correctly seated in its seat
(17).
ATTENTION:
Never charge batteries with
a non-suitable charger.
Strictly follow the instructions
supplied by the battery
and charger manufacturer.
Solution tank
The capacity of the solution
tank is indicated in the
technical data. Remove the
solution tank cap (15) placed
in the top part of the machine
and fill the solution tank with
clean water at a maximum
temperature of 122°F (50°C).
Add liquid detergent in the
percentage and conditions
recommended by the
manufacturer. To avoid
excessive foaming, which
could cause problems to
the vacuum motor, use the
minimum percentage of
detergent. Screw down the
cap to close the tank.
ATTENTION:
Always use low foam
detergent.
To avoid excessive foaming,
before starting working
operation, add into the
recovery tank a minimum
quantity of anti-foam product.
