amount of detergent dispensed; the dilution of the
detergent dispensed is displayed on the control panel
(Photo N - 7) through progressive levels highlighted in
the graphic symbol (Photo O).
The percentage of dilution of the detergent varies depen-
ding on the amount of clean water delivered, adjustable
through the control lever (Photo H - 1); when the clean
water outflow is half of the total possible amount, the
percentage of dilution is shown in Photo O - 1; when the
clean water outflow is set on the full amount the dilution
percentage is shown in Photo O - 2.
7.7.3 DIRECT SCRUBBING OR FOR SLIGHTLY DIR-
TY SURFACES
Scrubbing and drying in a single pass.
Prepare the machine as previously described.
Select the forward direction using the direction lever.
Insert and turn the key.
Activate the suction motor, the brush motor and the de-
tergent solution supply.

the way to one side.
To avoid damage to the surfaces being treated, the brush
motor will stop automatically about 2 seconds after the
advancement pedal has been completely released.
• Remember to lift the squeegee before driving re-
verse to avoid damaging it.

POST-SCRUBBING OPERATIONS

Cut off the supply of detergent.
Lift the brush unit and turn off the brush motor.
After having completely dried any traces of water on the
surface, wait a few seconds and then lift the squeegee
and turn off the suction motor.
Move to a suitable location to drain the tanks (as de-
scribed in 7.4 and 7.5).
Empty and clean the tanks (see sections 7.4 and 7.5).
Turn off the machine using the key and remove it from
the control panel.
If necessary, charge the battery (see the relative section).

8. MAINTENANCE INFORMATION

• Turn the key, remove it from the control panel and dis-
connect the battery from the machine wiring.
☞ All work on the electrical system as well as all mainte-
nance and repair operations (especially those not explic-
itly described in this manual) should be carried out only
by authorised service centres or by specialised technical
personnel who are experts in the sector and in the perti-
nent safety regulations.
Performing regular maintenance on the machine, and
carefully following the manufacturer's instructions, is the
best guarantee for obtaining the best performances and
extended machine service life.
8.1

TANKS

Drain the two tanks as described in the relative sections.
Remove any solid dirt by filling and draining the tanks
until all dirt has been eliminated: use a washing hose or
similar tool to do this.
• Water hotter than 50°, a high-pressure cleaner or
excessively powerful sprays may damage the tanks
and the machine.
Leave the covers of the tanks open (only while the ma-
chine is not being used) so that they can dry and thus
prevent the formation of foul odours.
8.2

SUCTION HOSE

Detach the suction hose from the squeegee.
Pull out the suction hose from its connection hole placed
in the recovery tank.
Now you can wash the hose and remove any obstruc-
tions.
After the cleaning, firmly insert again the suction hose
inside connection hole placed in the recovery tank.
Firmly insert the hose on the squeegee body.
