ATTENTION:
Use always low foam detergent. To avoid foam pres-
ence, before starting working operation, introduce
into the recovery tank a minimum quantity of anti-
foam product.
Never use pure acid.
3S SYSTEM “SOLUTION SAVING SYSTEM” (OP-
TIONAL)
The need of an increasing carefulness to the envi-
ronment, and to the abuse of polluting elements,
such as detergents in the floor cleaning machines,
has brought us to the realization of a device which,
regardless from the capacity to use the machine by
the operator, keeps the minimum flow of the deter-
gent solution constant, having been properly cali-
brated by an expert technician. The best detergent
solution amount with this system will be the one
which realizes the minimum flow of detergent solu-
tion sufficient to clean correctly the floor. For this
reason the system is called “
Solution Saving System”
abbreviated to “
3S” system.
The system is composed by a hydraulic circuit paral-
lel to the traditional one which can be enabled or
disabled directly from the instrument board through
a 3-position switch with the following functions:
(1) = Position solution valve with traditional func-
tioning with variable water flow that differs by the
opening of the solution valve.
(2) = Position STOP with functioning without flow
(drying only).
(3) = Position 3S with functioning with optimal
fixed flow.
STARTING OF THE MACHINE
1. Turn the key (9) clockwise.
2. Check the battery type and the charge level on
the display (1).
3. Press the brushes motor switch (6).
4. Press the suction motor switch (3).
5. Press the solenoid valve switch (5).
6. Lower the brushes base onto the floor.
The machines which have the electrical brushes base
lifting press the push button (7) of up/down of the
brushes base.
7. Acting upon the solution valve lever (14) open
and adjust the detergent solution flow.
The water starts to flow automatically acting upon
the levers drive control (12). On the instrument
board the indicator of the solenoid valve switch (5)
will turn on. Releasing these levers, the flow will stop.
Models equipped with the 3S system (optional), it is
necessary to press the suitable switch to activate the
detergent solution supply by choosing between the
traditional adjustment system through the solution
valve or the system of fixed optimum supply (see
under “3S SYSTEM SOLUTION SAVING SYSTEM”).
8. Acting upon the squeegee lifting lever (17) lower
the squeegee.
9. Acting upon the levers drive control (12) the ma-
chine starts to move, the brushes start to rotate and
the squeegee starts to dry.
10. During the first metres check that the squeegee
adjustment guarantees a perfect drying action and
that the detergent solution flow is appropriate. It
has to be sufficient to wet the floor uniformly avoid-
ing the leakage of detergent from the splash guards.
Always consider that the correct quantity of solution
detergent depends on type of floor, dirtiness and
machine speed.
FORWARD MOVEMENT
The traction of the machine is given through an
electronically controlled motor.
To move the machine, act upon the key (9) and then
rotate the levers drive control (12) placed on the
handle bar, in forward you obtain the forward drive,
in reverse the backwards movement is obtained. The
control acts in a progressive way, therefore it is pos-
sible to graduate the speed depending on each re-
quirement rotating the lever whatever it is necessary.
During reverse motion the speed is reduced.
SPEED ADJUSTMENT
Two values of the maximum drive working speed in
forward movement can be chosen.
Set the wanted speed through the speed selection
switch (2).
ATTENTION:
Moving the machine backwards, make sure that the
squeegee is lifted.
SECURITY DEVICE REVERSE MOVEMENT
A large-sized push button (13), placed on the rear
extremity of the machine is for the automatic drive
inversion. If the operator unintentionally remains
blocked between the machine and an obstacle, this
push button gives the control to invert the machine
when it touches the operator.
WORKING BRAKE
To stop the machine during normal working situa-
tion, it is sufficient to release the levers drive control
(12), as the machine is equipped with an electronic
braking system. The brushes and the detergent solu-
tion flow stop automatically.
EMERGENCY BRAKE
In case of an emergency, an immediate stop can be
obtained acting upon the lever of the emergency
and parking brake (16) by pushing it downwards.
ATTENTION:
This control blocks the machine immediately. The
emergency brake functions also as a parking brake.
To start again to work, release the lever by unblock-
ing the parking button on the lever itself and act
again upon the levers drive control (12).
ADJUSTMENT OF THE BRUSHES PRESSURE
Through the register (1) it is possible to adjust the
brushes pressure on the cleaned surface.
By turning the knob clockwise the pressure increases,
rotating it counterclockwise, the pressure decreases.
This device allows a more efficient cleaning action
also on very difficult and dirty surfaces.
The control of the adjustment value of the set pres-
sure is possible through a sliding indication. Its posi-
tion shows the value indicated on the label placed in
correspondence of the slots where it slides.
On the 24 Volt machines the indicator is placed in
the rear part of the frame inside the battery com-
partment.
