After the detergent solution is finished, always empty
the recovery tank before filling it again.
In general, the recovery tank can be emptied whenever
required, and even during intermediate phases of the
work cycle.
Always empty the recovery tank before lifting it to
avoid health problems for operators and to avoid
damaging the machine.
The recovery tank volume is higher than the detergent
solution volume, therefore a potentially dangerous
situation for the suction motor should never occur. In
any case, a safety float turns of f the suction motor if
the dirty liquid level is too high.
If water or foam starts leaking from under the tanks
for any reason, immediately turn off the suction motor
and empty the recovery tank.
To drain the tank:
Drive the machine to a suit able location to drain the
dirty water and preferably near a toilet or a sewer drain
(comply with the national regulations for waste water
disposal).
Turn off the machine and remove the key from the
panel.
Detach the drain hose from the hook and, keeping it
high, unscrew the plug.
Lower the drain hose toward the selected drainage
point.
The emptying operation can be interrupted quickly and
whenever required just by raising the drain hose.
Check the quantity of residual dirt in the t ank and, if
necessary, clean the interior through the inspection
hole, lifting the cover and the funnel at the top.
Carefully position the funnel inside the inspection hole
and close the top cover , tightening the lock handles
after each inspection/cleaning operation.
Fully tighten the drain hose with the screw plug and
hang it on the support behind the machine.
The top cover of the tank and the drain hose plug
must be airtight, otherwise the subsequent pressure
loss will reduce drying efficiency.

7.6 SEAT ADJUSTMENT

Before adjusting the seat, make sure that the machine
is turned off and that the key has been removed from
the dashboard.
If necessary, the position of the driver 's seat can be
changed.
To change the seat adjustment, release the locking
lever and move the seat to the required position.
Make sure that the locking lever is securely fixed at the
end of the adjustment.
Check that the seat is in a st able position and firmly
secured.

7.7 DRIVING THE MACHINE

Select the running direction using the Forward/Reverse
lever.
Insert and turn the ignition key.
Release the parking brake.
Using the right foot lightly press the accelerator pedal
and drive the machine to its destination.
After reaching the destination, release the accelerator
and engage the p arking brake, braking with the lef t
32
pedal and activating the pedal locking lever.
Turn off the machine and remove the keys from the
control panel.
The running direction can be changed using the
forward/reverse lever, even while pressing on the
accelerator pedal.

7.8 WORK METHOD

7.8.1 PREPARATION AND WARNINGS

Remove any loose solid residue from the surface to be
treated (using suitable tools, such as vacuum cleaners,
sweepers, etc.). It this is not done, the solid dirt might
prevent the squeegee from operating correctly, reducing
drying efficiency.
This machine can driven only by trained personnel.

7.8.2 OPERATING CONTROLS

• Ignition key, to turn the machine on and off.
• Direction lever , to select forward or reverse
movements.
• Speed regulator, to select the maximum advancement
speed when the pedal is fully depressed.
• Brush switch, to turn on the brush rotation motor.
• Brush position switch, to lower (work position) or
raise (rest/movement position) the brush unit on/from
the floor.
• Suction switch, to turn on the suction motor.
• Squeegee position switch, to lower (work position)
or raise (rest/movement position) the squeegee.
• Emergency switch, to cut off/restart all programmed
work operations.
• Right advancement pedal, to start moving the machine.
• Left brake pedal, to quickly stop machine movement.
• Solution flow adjustment lever, to regulate the quantity
(maximum toward the top, minimum toward the bottom)
of detergent solution to be applied on the floor.
• Battery charge control, the sequence of light s
progressively turns off until the battery is discharged.
When the red light turns on, turn of f the brush motor,
close the solution supply, finish drying the small residual
moisture and go to the battery charging area to charge
the battery. If these operations are not carried out, the
machine will automatically deactivate the brush motor
and it will only be possible to move the machine. In this
situation if the machine is not stopped right away , all
functions will be cut off automatically, and the machine
will have to be moved by hand.
• The batteries may be irreparably damaged if the
residual charge level drop s too low (see the battery
operating manual). Do not force the battery discharge
beyond the safety limits, turning the key off and on or
in any other manner.
• When an abnormal situation occurs, such as when
the machine doesn't have enough power and the safety
devices don't trip, stop immediately: follow the
instructions in the troubleshooting section and contact
a specialised worker to check the discharge control
devices.
7.8.3 DIRECT SCRUBBING OR FOR SLIGHTLY DIRTY
SURFACES
Scrubbing and drying in a single pass.
Prepare the machine as previously described.
Select the forward direction using the direction lever.
