Before the first use of the machine it is necessary
to set the electronic card for the operation of the
machine with Pb-Acid or Gel batteries through the
selector (Photo M - 1).
To reach the electronic card it is necessary to ex-
tract the hour meter (Photo M); through the lod-
ging hole of lodging of the hour meter it is possible
to reach the selector with a screwdriver;
☞
( ) Put the selector to the right if the machine is
provided with Pb-Acid batteries, or to the left if the
machine is provided with GEL batteries (Photo M -
1 ).

6.4 MACHINE PREPARATION

!
( ) Before starting to work, wear non-slip shoes,
gloves and any other personal protection device in-
dicated by the supplier of the detergent used or
considered necessary based on the operating envi-
ronment.
☞
( ) Do the following before starting to work. Refer
to the relative sections for a detailed description of
these steps:
check the battery charge level and charge, if ne-
cessary.
Mount the brushes or scraper disks (with the abra-
sive disks) that are suitable for the surface and
work involved.
Mount the squeegee, check that it is solidly atta-
ched and connected to the suction hose and that
the drying blades are not too worn.
Make sure that the recovery tank is empty. If not,
empty it completely.
Check and completely close the detergent solution
release control.
Fill the detergent solution tank with a mix of clean
water and non-foaming detergent in an adequate
concentration through the anterior hole. Leave 2
cm between the mouth of the plug and the level of
the liquid.
☞
( ) To avoid risks, become familiar with the ma-
chine movements, carrying out test runs on a large
surface without obstacles.
To obtain the best results in terms of cleaning and
equipment service life, you should do the following
simple but important operations:
- Identify the work area, moving all possible obsta-
cles out of the way; if the surface is very extensive,
work in contiguous and parallel rectangular areas.
- Choose a straight work trajectory and begin wor-
king from the farthest area to avoid passing over
areas that have already been cleaned.

7. OPERATING INFORMATION

7.1 BATTERY CHARGING

Prepare and check the battery charge according to
the instructions provided in the specific section.
Detach the battery connector from the machine
power connector (the one with the gripping fins)
and connect the battery connector to the battery
charger connector.
!
( ) Do not connect the battery charger to the
scrubber-drier's main wiring connector.
Hold the connectors with the hands; do not pull
them using the cables.
If the machine is equipped with Pb-Acid batte-
ries, charge only in a well-ventilated area, lift the
superior cover and open the battery plugs.
( ) Follow the steps indicated in the battery ma-
nufacturer's operating and safety manual (see the
battery maintenance section).
If the machine is equipped with gel batteries
(maintenance free), follow the instructions indica-
ted here below.
If the machine is used regularly:
Always keep the batteries connected to the battery
charger when the machine is not being used.
If the machine is not used for extended time pe-
riods:
Charge the battery during the night after the last
work period, then disconnect the battery from the
battery charger.
Charge the battery during the night before using
the machine again.
Intermediate or incomplete charging while working
should be avoided.
If the machine is equipped with Pb-Acid batteries,
use a hydrometer to check the element liquid in-
tensity on a regular basis: if one or more elements
are discharged and the others fully charged, the
battery has been damaged and should be replaced
or repaired (refer to the battery service manual).
Close the element plugs and lower the superior
cover.
Hold the connectors with the hands; don't pull
them using the cables.
Reconnect the machine connectors.
7.2 SQUEEGEE AND SPLASH GUARD ASSEM-
BLY, DISASSEMBLY AND ADJUSTMENT
The squeegee is the main component that ensures
perfect drying.

7.2.1 SQUEEGEE ASSEMBLY

Slightly screw the two knobs ( Photo O - 7 ) into
the squeegee body and insert the squeegee into
the slots situated on the squeegee support.
Screw the two knobs ( Photo O - 7 ) in order to se-
cure the squeegee to the support.
Firmly insert the suction hose ( Photo O - 1 ) into
the pipe in the squeegee body.

7.2.2 SQUEEGEE DISASSEMBLY

Disconnect the suction hose from the squeegee
body.
Unscrew the two knobs ( Photo O - 7 ) that secure
the squeegee to its support and pull the squeegee
to free it.
