BATTERY CHARGING

Prepare and check the battery charge according
to the instructions provided in the specific section.
Connect the battery charger connector to the ma-
chine connector (Photo F - 9); then, connect the
battery charger to the mains power.
Do not connect the battery charger to the scrub-
ber-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 batteries,
charge only in a well-ventilated area, lift the supe-
rior cover and open the battery plugs.
Follow the steps indicated in the battery manu-
facturer'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.

SQUEEGEE ASSEMBLY

Slightly screw the two knobs (Photo M - 7) into the
squeegee body and insert the squeegee into the
slots situated on the squeegee support.
Screw the two knobs (Photo M - 7) in order to
secure the squeegee to the support.
Firmly insert the suction hose into the pipe in the
squeegee body (Photo M - 1).
6.5

SQUEEGEE DISASSEMBLY

Disconnect the suction hose from the squeegee
body.
Unscrew the two knobs (Photo M - 7 ) that secure
the squeegee to its support and pull the squeegee
to free it.
6.6

SQUEEGEE BLADES

DISASSEMBLY/ ASSEMBLY
Disassemble the squeegee from its support (see
6.5)
Unscrew the knobs (Photo M - 3) (Photo M - 7)
placed on the squeegee body and apply some pres-
sure on their bolts in order to push out the plastic
support of the squeegee blades from the squeegee
body.
Tear off the rubber blades from the plastic support.
Assemble the new blades on the plastic support by
the means of the plastic pins that have to be fixed
in the holes placed the blades.
To reassemble, push the plastic support of the
squeegee blades into the squeegee body and
screw the knobs (Photo M - 3) (Photo M - 7) to
secure it to the squeegee body.
Reassemble the squeegee to its support (see 6.4).
6.7

SQUEEGEE ADJUSTMENT

The knob screw on the squeegee support (Photo M
- 2) adjusts the squeegee's inclination with respect
to the floor. The two red knobs on the sides, con-
nected to the rear wheels of the squeegee (Photo
M - 5) are to adjust the pressure of the squeegee
to the floor.
When the squeegee is perfectly adjusted, the rear
squeegee blade, sliding as it moves, bends in all
points forming an angle of 45° with the floor.
As the machine operates (advances), the knobs
(Photo M - 2) (Photo M - 5) can be used to adjust
the inclination and pressure of the squeegee blades
on the floor.
Squeegee drying must be uniform along the entire
drying line: damp patches mean that drying is in-
sufficient; turn the adjustment knobs to optimize
drying.
6.8 SPLASH GUARD ASSEMBLY/ DI-
SASSEMBLY
The splash guard is assembled to the brush plate
with a spring holder linked to the brush plate itself
(Photo N - 1).
To disassemble the splash guard simply detach the
spring holder and pull the splash guard.
To reassemble, fix the splash guard in the brush
plate, and then hook the steel cable to one side of
the plate and the spring holder to the other side of
