CAUTION –
CONSULTATION –

While reading this Manual, the operator must pay particular attention to the symbols shown on the plates.
Do not cover these plates for any reason and immediately replace them if damaged.

BATTERY CHECK/SETTING ON A NEW MACHINE

WARNING!

The electric components of the machine can be seriously damaged if the batteries are either improperly installed
or connected. The batteries must be installed by qualifi ed personnel only. Set the function electronic board and
the built-in battery charger according to the type of batteries used (WET or GEL).
Check the batteries for damage before installation.
Disconnect the battery connector and the battery charger plug.
Handle the batteries with great care.
Install the battery terminal protection caps supplied with the machine.

The machine requires two 12 V batteries, connected according to the diagram (49).

The machine can be supplied in one of the following modes:

Batteries (WET or GEL) already installed and ready to be useda)

Check that the batteries are connected to the machine with the connector (12).1.
(Only for 2. RAZOR™ 20T): Insert the ignition key (80) and turn it to “I”.
(Only for RAZOR™ 20): Turn on the machine by pressing the switch (71) and/or (73).
If the green warning light (81a) turns on, the batteries are ready to be used.
If the yellow or red warning light (81b) or (81c) turns on, the batteries must be charged (see the procedure in Maintenance
chapter).

Batteries (WET) installed on the machine, but without electrolyteb)

Open the cover (22) and check that the recovery tank (21) is empty, otherwise empty it with the drain hose (16).1.
Carefully lift the tank (40).2.
Remove the caps (47) of the batteries (46).3.

WARNING!

Pay attention when using sulphuric acid, as it is corrosive. If it comes in contact with skin or eyes, rinse
thoroughly with water and consult a physician.
Batteries have to be fi lled in a well-ventilated area. Wear protective gloves.

Fill up the battery elements with sulphuric acid for batteries [density 2.79 to 2.84 lb at 77°F (1.27 to 1.29 kg at 25°C)] as 4.
shown in the Battery Manual. The correct quantity of sulphuric acid is shown in the Battery Manual.
To avoid damaging the fl oor, dry with a cloth both acid and water on the top of the batteries after charging.5.
Let the batteries rest and fi ll in with sulphuric acid as shown in the Battery Manual.6.
Charge the batteries (see the procedure in Maintenance chapter).7.

Without batteriesc)

Buy appropriate batteries (see the Technical Data paragraph).1.
For battery choice and installation, apply to qualifi ed battery Retailers.2.

CAUTION!

To avoid any damage to the fl oor surface, turn off the brush/pad-holder when the machine stops in one place,
especially when the extra pressure function (optional) is on.

Working with brush/pad-holder extra pressure function activated

If the fl oor proves to be particularly diffi cult to clean, it is possible to turn on the brush/pad-holder extra pressure function by
pressing the pedal (11) to position (11c).

CAUTION!

In case of brush/pad-holder motor overload, due to foreign bodies which prevent them from turning, or to
excessively aggressive fl oors/brushes, the safety system stops the motor after about one minute of continuous

The overload is shown by the three warning lights (81a, 81b, 81c) fl ashing simultaneously.
If the overload takes place when the extra pressure function is on (11c), press the pedal to position
(11b). If the overload persists, the brush/pad-holder stops.
To start scrubbing again after a brush/pad-holder stop due to overload, stop the machine by turning the ignition
key (80) to “0”. Turn on the machine by turning the ignition key (80) to “I”.

INSTRUCTIONS FOR USE

Battery discharge during operation

Until the green warning light (81a) stays on, the batteries allow the machine to work normally.
When the green warning light (81a) turns off, and the yellow warning light (81b) turns on, it is advisable to charge the batteries,
because the residual autonomy will last for a few minutes (depending on battery characteristics and work to be performed).
When the red warning light (81c) turns on, the autonomy is over. After a few seconds, the brushes/pad-holder is automatically tuned
off, while the vacuum system and (only for RAZOR™ 20T) the drive system stay on, to fi nish drying the fl oor and drive the machine
to the appointed recharging area.

CAUTION!

Do not use the machine with discharged batteries, to avoid damaging the batteries and reducing the battery life.

TANK EMPTYING

An automatic fl oat shut-off system (36) turns off the vacuum system when the recovery tank (21) is full.
The vacuum system deactivation is signaled by a sudden increase in the vacuum system motor noise frequency, also the fl oor has
not dried.

CAUTION!

If the vacuum system turns off accidentally (for example, when the fl oat is activated because of a sudden
machine movement), to resume the operation: turn off the vacuum system by pressing the switch (73), then
open the cover (22) and check that the fl oat inside the grid (36) has gone down to the water level. Then close the
cover (22) and turn on the vacuum system by pressing the switch (73).

When the recovery tank (21) is full, empty it according to the following procedure.

Recovery tank emptying

Stop the machine.1.
Lift the brush/pad-holder deck by pressing the pedal (11).2.
Lift the squeegee (25) with the lever (10).3.
Drive the machine to the appointed disposal area.4.
Empty the recovery tank by means of the hose (16). Then, rinse the tank with clean water.5.

Solution tank emptying

Perform steps 1 to 4.6.
Empty the solution tank with the hose (17). Then, rinse the tank with clean water.7.

AFTER USING THE MACHINE

After working, before leaving the machine:

Remove the brush/pad-holder according to the procedure shown in the relevant paragraph.1.
Empty the tanks (20 and 21) according to the procedure shown in the relevant paragraphs.2.
Perform the daily maintenance procedures (see the Maintenance chapter).3.
Store the machine in a clean and dry place, with the brush/pad-holder and the squeegee lifted or removed.4.

MACHINE LONG INACTIVITY

If the machine is not going to be used for more than 30 days, proceed as follows:

Perform the procedures shown in After Machine Use paragraph.1.
Disconnect the battery connector (12).2.

FIRST PERIOD OF USE

After the fi rst 8 hours, check the machine fastening and connecting parts for proper tightening and check the visible parts for
integrity and leakage.

BATTERY CHARGING

NOTE

Charge the batteries when the yellow or red warning light (81b or 81c) turns on, or at the end of every working cycle.

CAUTION!

Keeping the batteries charged make them last longer.

CAUTION!

When the batteries are discharged, charge them as soon as possible, as that condition makes their life shorter.
Check for battery charge at least once a week.

WARNING!

WET battery charging produces highly explosive hydrogen gas. Charge the batteries in well-ventilated areas and
away from naked fl ames. Do not smoke while charging the batteries.
Keep the tank assembly open while charging the batteries.

WARNING!

Pay careful attention when charging the batteries as there may be battery fl uid leakages. The battery fl uid is
corrosive. If it comes in contact with skin or eyes, rinse thoroughly with water and consult a physician.

Preliminary procedures

Open the cover (22) and check that the recovery tank (21) is empty, otherwise empty it with the drain hose (16).1.
Drive the machine to the appointed recharging area.2.
(Only for 3. RAZOR™ 20T): Turn the ignition key (80) to “0”.
(Only for RAZOR™ 20): Turn off the machine by pressing the switch (71) and/or (73).
Carefully lift the tank (40).4.
For WET batteries only:5.

Check the level of electrolyte inside the batteries (46); if necessary, top up through the caps (47).•

Then leave all the caps (47) open for battery charging.•

If necessary, clean the upper surface of the batteries.•
Connect the battery charger cable (6) to the electrical mains (the electrical mains voltage and frequency must be compatible 6.
with the battery charger values shown on the machine serial number plate (34)).
When the battery charger is connected to the electrical mains, all machine functions are automatically cut off.
If the red warning light (94) on the battery charger control panel stays on, the battery charger is charging the batteries.
When the green warning light (92) turns on, the battery charging is completed.7.
When the battery charging is completed, disconnect the battery charger cable (6) from the electrical mains and wind it round 8.
