The battery charger can be transported on its supports,

both  vertically  and  horizontally.  Take  the  same

precautions and follow the same instructions provided

for the machine together with those in the special

manufacturer’s manual.

5. TECHNICAL INFORMATION

5.1 GENERAL  DESCRIPTION

5.1.1 MACHINE

We can summarise the machine’s main features as

follows:

- The form of the squeegee, the air flows and the

specially designed rubber blades produce excellent

drying results even on tiled floors. Thanks to the particular

balanced shape of the machine frame and the squeegee

support, no water residues are left behind in a curve,

and even when a smaller squeegee is used.

- Excellent distribution of weights and geometries: the

centre of gravity is very low, also thanks to the very

heavy brush plate and because the batteries are located

at the level of the wheels.

- A heavy weight on the brushes makes them work

efficiently on the floor. The pressure is generated by

the weight of the plate, without springs or additional

devices that lead to difficulties and inaccuracy. The

entire mass is generated by the hanging weight of a

15 mm steel ship’s plate.

- A large volume of water in the tanks reduces dead

time since fewer trips are needed to collect water and

dump dirt. There is no delicate flexible diaphragm that,

at a technical level, is difficult to clean.

- Some dozen litres of water in the recovery tank are

used to decant any foam (dangerous for the suction

motor). The traction system is designed for the machine

weights, making the machine responsive and easy to

handle.

- Robust construction. The frame and the squeegee,

built with thick sheet metal - thickness 6 mm, 8 mm, 10

mm up to 20 mm – are laser cut and welded. The brush

plate is made from 15 mm ship’s sheet metal, with a

surface treatment that protects the plate and the paint

for thousands of hours in a saline fog. All screws are

made with stainless steel; the tanks (body) are made

with 7-8 mm thick shockproof polyethylene. Everything

is simple and very strong, without any other complicated

designs.

-  The  battery  compartment  can  house  very  large

batteries, which guarantees extended running time.

- The suction motor is housed inside the machine, thus

reducing operating noise to a minimum.

- The recovery tank is very easy to clean due to the

lack  of  the  characteristic  difficult  access  points  of

recovery tanks located in a lower position.

5.1.2 BATTERY

Regardless  of  the  type  of  construction,  battery

performances are indicated with the term capacity,

which always refers to a discharge period. Another

important value is the number of possible discharges.

The capacity is expressed in amps per hour (Ah), while

the discharge period is generally indicated as 20 hours

(C20 or 20h, or not expressly indicated) or 5 hours (C5

or 5h). The discharge/charge cycles indicate the number

of times that the battery can hold a charge under the

best conditions, i.e. they indicate the useful battery

service life complying with all the necessary measures.

Therefore, the capacity of a battery varies depending

on how fast it uses energy (current). That’s why there’s

such a variation in the capacity values expressed as

C5 or C20. These factors must be taken into account

when comparing products available on the market with

our own.

This machine can be equipped with two types of batteries

that differ in terms of their construction and features.

- Pb-Acid battery the electrolyte level in each element

must be periodically checked!

If one element is no longer covered by the acid

solution it will oxidise in 24 hours, thus permanently

affecting that element’s performance.

 Refer to the battery manual to avoid physical damage

and economic loss.

- Gel battery this type of battery is maintenance free

and does not require special environments for recharging

(since it does not emit any harmful gases); therefore,

it is highly recommended.

It should not be taken for granted that batteries

and  battery  chargers  with  the  same  technical

features as those we offer will produce the same

results. Only perfect compatibility between these

elements (Pb-Acid batteries, gel batteries and battery

chargers) will safeguard the performances, the

service life, the safety and the economic value

invested.

5.1.3 BATTERY CHARGER

This type of high-frequency battery charger efficiently

charges batteries, extending their operating and service

life. The same battery charger can be used for both

Pb-Acid batteries and for gel batteries.

The information indicated on the digital display can be

used to always keep the charging process, the battery

and the battery charger under control (read the specific

manual for more details).

It should not be taken for granted that batteries

and  battery  chargers  with  the  same  technical

features as those we offer will produce the same

results. Only perfect compatibility between these

elements (Pb-Acid batteries, gel batteries and battery

chargers) will safeguard the performances, the

service life, the safety and the economic value

invested.

5.2.2 BATTERY

If supplied, the Pb-Acid (if not dry charged) or gel

batteries are ready to be installed:

Positive pole - red

Negative pole - black.

5.2.3 BATTERY CHARGER

If supplied, refer to the corresponding booklet.

5.3 ACCESSORIES

Your machine supplier can provide a complete and

updated list of all available accessories, such as brushes,

scrapers, disks, etc.

6. INSTALLATION INFORMATION

6.1 BATTERY PREPARATION

 The technical features of the batteries used must

match those indicated in the technical features section.

Using different batteries may cause serious damage to

the machine or may require them to be charged more

frequently.

 During installation or when performing any type of

battery maintenance, the operator must be equipped

with adequate safety accessories to prevent accidents.

Work far from open flames, do not short-circuit the

battery poles, do not generate sparks and do not smoke.

The batteries are normally supplied full of acid solution

(for the Pb-Acid type) and ready for use. In any case,

follow the steps indicated in the manual supplied with

the battery and carefully follow the instructions regarding

safety and operating procedures.

6.2 BATTERY INSTALLATION AND PREPARATION

 These operations must be carried out by specialised

personnel.

Make sure the two tanks are empty. If not, empty them

in accordance with the specific procedure.

Lift the recovery tank by 90°, making sure it is stable

in that position. This provides access to the battery

compartment from the top.

Disconnect the Anderson connector of the battery wiring

from the Anderson connector of the machine wiring.

Always hold the connectors with the hands and never

pull on the cables.

 Attach the battery wiring to the battery, connecting

the terminals only on the poles marked with the

same symbol (red wiring “+”, black wiring “-“)! A

battery short-circuit may cause an explosion!

Tighten the terminals at the poles and cover them with

Vaseline.

After checking that all the controls on the panel are in

position “0” or at rest, connect the battery connector to

the machine connector.

 Close the battery compartment (lowering the recovery

tank) making sure not to crush any wires.

6.3 BATTERY CHARGER PREPARATION

6.4  BATTERY  CHARGER  INSTALLATION  AND

CONNECTION

The battery charger is generally supplied ready to use

if requested with a specific battery. Make sure that the

battery charger was correctly programmed to charge

the battery supplied: when the machine is switched on,

the display will indicate the charge settings. Check the

voltage and charge current relative to the type of battery.

If the battery charger and battery settings do not
