Outlet (picture 3), it is the same used for the battery charger. In casa of emergency,
the operator must the plug must be taken out of the outlet by means of its handle
(picture 4).
Before using the machine, the operator must know how the safety system of the
machine works. It is forbidden to plug in, if the problem has not been sorted
completely out. If necessary, ask for a trained technician.
Float:the recovery tank is equipped with a float that stops the machine if the tank is
too full. In this case, before restarting the machine the operator has to empty the
recovery tank o (see page 11). When the machine stops because the recovery tank is
full, the battery charger indicator on the dashboard blinks six times.
Unsufficient battery charge:The electronic card, that controls every function of the
scrubber machine, is equipped with a safety system that stops all the machine
functions (except for the traction) when the batteries autonomy is lower than 20%.In
this way, the batteries lifetime lasts longer.

BATTERY CHARGER INSTALLATION
??Install the battery charger in a ventilated and dry place, far from heat sources and
corrosive substances;
??Protect the mains with a delayed switch or with a fuse whose load is higher than
the maximum absorbtion of the battery charger .
??Do not invert the polarities of the battery charger outlet.
CHOOSING THE DETERGENT
For a good floor cleaning, it is important to choose the right detergent solution. Atoo
strong detergent can compromise the machine lifetime. It is necessary to use a
controlled foam detergent, or an antifoaming additive, in order to avoid damaging the
suction engine. Otherwise, the operator can use vinegar to avoid foam and pour 50cc of
it in the recovery tank before scrubbing.
STARTING AND PREPARING THE MACHINE
If the machine is connected with the battery charger, the operator must firstly
disconnect the battery charger plug from the batteries one and connect the batteries
plug with the power supply plug (see picture 4). Secondly, the operator must fill water
lifting the recovery tank up and turning the cap. Now the operator can seat on the
machine, start it and wash the surface.
USE OF THE MACHINE
The operator, thanks to his/her experience, has to choose the right type of brush and
detergent for the surfaces that has to be cleaned and to decide if the floor needs a
second washing.
Follow these instructions for a correct washing:
1. press the brushes motor switch;
2. press the solution solenoid valve switch;
3. press the suction switch.
By means of the accelerator pedal the washing brushes and the suction motor are
activated. On the contrary, both the washing brushes and the suction engine are
disactivated after a few seconds if the operator leaves the accelerator pedal. Before the
surface is completely dry, the operator must switch the solution solenoid valve off
because this is not activated/disactivated by the accelerator pedal.
The operator has to do a second washing if the surface is particularly dirty:
1. wash the surface with the squeegee up and the brushes down;
2. activate the brushes;
3. press the solution solenoid valve switch;
4. leave the solution on the surface to dissolve the dirt;
5. do a second washing with brushes and squeegee down, the suction activated and the
solution solenoid valve opened.

11
DETERGENT QUANTITY
During the cleaning the operator can control the detergent quantity by means of a
cock, which is on the left of the machine frame.
Important: before checking the water quantity that flows to the brushes, make sure
that the ignition key is not in the dashboard in order to avoid a casual starting of the
machine.

HYDROMETRY
In order to check the batteries hydrometry the operator has to follow the instructions
below:
1. By means of a hydrometre draw a small quantity of electrolyte so that the floater
reaches the surface;
2. Make sure that the floater inside the hydrometre is not blocked;
3. For a new measurement, after having filled the batteries with distilled water, the
operator has to wait until the liquid inside each battery becomes homogeneous.

17
WATER FILLING UP
1. Fill distilled water up in each battery cell before the recharge. The liquid inside the
batteries has to be of 6 mm. over the plates;
2. The operator has to repeat the same operation every time the level decreases (every
week).
CHARGE LIMITS
It is not necessary to recharge the batteries if the hydrometry, after a work day, is not
under 1,24 (28 Bè). The highest suggested temperature is 45°C. If the electrolyte
temperature increases more than 10/12 °C compared to the outside temperature, the
batteries can be overcharged.
OFF DUTY OR INACTIVE BATTERIES
Inactive batteries looses their automatically their charge. If batteries do not
continually work, the operator has to:
??Charge the batteries once a month with a ‘final’ stream intensity until gas is
spread and the batteries voltage and weight are constant for 3-4 hours. This
operation has to be done even if the absolute weight is high;
??Keep the batteries in a dry room.
