Recovery Tank; Detergent Solution Tank; System "Solution Saving System" (Optional); Floor Cleaning - Tornado BD 20/11T Mode D'emploi

3. With the brush base group in lifted position, in-
sert the brush into its plate seat underneath the
brush base turning it until the three metal buttons
are properly seated in their slots; rotate energically
the brush to push the button towards the coupling
spring until it gets blocked.
The figure shows the rotating sense for the brush
coupling of the ruby50t.
The following figure shows the rotating sense for the
brushes coupling of the models ruby45t and ruby55t.
For a longer life of the brushes we suggest to invert
daily their position. Whenever brushes were de-
formed we suggest to reassemble them in the same
position, avoiding that the different inclination of
the bristles causes excessive motor overload or trou-
blesome vibrations.
ATTENTION:
Use only brushes supplied with the machine or the
ones indicated in the paragraph "RECOMMENDED
BRUSHES". The use of other brushes can compromise
the security.

RECOVERY TANK

Check that the cover of the suction filter (1) is cor-
rectly secured, after rotating the levers and that the
suction motor hose (2) is correctly connected.
Verify also that the squeegee hose is correctly insert-
ed into the seats (3 and 4) and that the exhaust hose
plug (5) placed in the front part of the machine, is
closed.

DETERGENT SOLUTION TANK

The capacity of the detergent solution tank is indi-
cated in the technical data.
Open the screw plug (1) placed in the rear left part
of the machine and fill the detergent solution tank
with clean water at a maximum temperature of 50°C.
Add the liquid detergent in the percentage and con-
ditions foreseen by the manufacturer. To avoid ex-
cessive foam presence, which could cause problems
to the suction motor, use the minimum percentage
of detergent. Screw down the plug to close the tank.
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 solution 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.
The hydraulic circuit of the 3S system is independent
and it is provided with a proper filter which has to
be cleaned regularly.
For the cleaning it is necessary to unscrew the plug
as shown in the figure and clean the inside filter
with a water jet.

FLOOR CLEANING

CONNECTION OF THE BATTERIES TO THE MA-
CHINE
Plug in the batteries connector (1) to the machine
connector (2), placed in the rear part of the machine.

STARTING OF THE MACHINE

1. Switch on the machine acting upon the general
switch (12). For machines equipped with key switch
(see under "OPTIONAL ACCESSORIES"), turn the key
(6) clockwise.
2. Press the brushes motor switch (5).
3. Check the battery type and the charge level on
the display (1).
4. Press the suction motor switch (3).
5. Acting upon the solution valve lever (8) adjust
the solution detergent quantity bringing the floor
uniformly wet, avoiding the leakage of detergent
from the splash guard. Always consider that the cor-
rect quantity of solution detergent depends on the
type of floor, dirtiness and machine speed.
