OVERFLOW DEVICE
In order to avoid serious
damages to the suction motor,
the machine is equipped
with a mechanical float that
intervenes when the recovery
tank is full, closing the air
flow of the suction. When
this happens, it is necessary
to empty the recovery
tank (see under paragraph
“RECOVERY TANK
EMPTYING
AND CLEANING”).
To restore the functioning of
the component, turn off and on
again the machine acting upon
the key switch. If the problem
persists, please contact
the authorized technical
assistance.
ATTENTION:
In manual mode every
function of the machine has
to be activated or deactivated
manually.
WORKING ADJUSTMENTS
Both in automatic and in
manual mode, during the first
feet (metres) check:
1. that the squeegee
adjustment guarantees
a perfect drying result
(see under paragraph
“ADJUSTMENT OF THE
SQUEEGEE”).
2. that the adjustment of
the detergent solution flow
is sufficient to wet the floor
uniformly avoiding the leakage
of detergent from the splash
guards (see under paragraph
“FLOW ADJUSTMENT OF THE
DETERGENT SOLUTION”).
3. that the brushes pressure
permits an efficient washing
action in function of the dirt
and the speed (see under
paragraph “ADJUSTMENT OF
THE BRUSHES PRES-SURE”).
FLOW ADJUSTMENT OF THE
DETERGENT SOLUTION
To adjust the detergent
solution quantity that flows
down onto the brushes it
is necessary to rotate the
solution valve knob (1)
placed on the right of the
steering column, rotating
counterclockwise to increase
it and clockwise to reduce it
up to close the flow.
It is better to adjust the water
flow during work and at every
adjustment
of the brushes
pressure.
ADJUSTMENT OF THE
BRUSHES PRESSURE
Through the knob (4) it is
possible to adjust the brushes
pressure onto the floor in three
pre-set pressure levels. We
can visualize on the display (1)
the pressure in kg previously
set by pressing the push
button (3).
The adjustment occurs in this
way both in automatic and in
manual mode.
ATTENTION:
In order not to overload the
brushes motor, it is convenient
to reduce the brushes
pressure going from smooth
floors to rough ones (ex.
concrete). The visualization of
the blinking led (2) indicates
an overload of the brushes
motor. It is therefore necessary
to reduce the pressure up to
the level where the blinking
warning stops.
ELECTRIC PROTECTION
The machine is equipped
with an electronic system of
protection for all components
that carry out functions
of power or control. This
device blocks the defective
component and indicates
on the display (1) the
corresponding alarm from
”A1”, “A2” and on.
