Tornado BR 28/27, Operation & Maintenance Manual

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.

3SD SYSTEM SOLUTION SAVING SYSTEM 

DISPENSER (OPTIONAL)

The system permits the predetermined dos-

ing of the detergent percentage which will be 

mixed with the water of the solution tank.

The system consists of a dual hydraulic circuit, 

one for the water and one for the detergent, 

each one equipped with a suitable pump.

The detergent is contained in a tank with a ca-

pacity of 2 gallons (8 litres), placed in the front 

part of the machine.

The tank is transparent, to enable the visual-

ization of the detergent level.

Pressing once the push button (A) on the in-

strument board, on the display (1) the indicator 

shows the detergent percentage which is being 

used.

Pressing the same push button in succes-

sion, six different possibilities of setting can be 

selected and the display (1) visualizes always 

the percentage.

The indication of the level corresponds to the 

following detergent percentages in the water:

d0 =    0 %

d1 = 0,3 %

d2 = 0,6 %

d3 = 1,2 %

d4 = 2,4 %

d5 = 4,5 %

The last dosing adjustment set remains stored 

by the system also with the machine stopped.

The dosing adjustment can be made only with 

the brushes moving (during operation), so that 

the dosing ratio cannot be modified acciden-

tally.

The water flow is adjusted through the 8-way 

commutator (B): one OFF position and 7 op-

erating positions from a minimum of .3 gallon 

(1,2 litres)/min to a maximum of 1 gallon (3,7 

lit)res/min.

In OFF position both the water flow and its 

relative detergent flow is interrupted.

NOTE: the detergent percentage in the water 

is in any case always constant independently 

from the level course of the water set. 

The water flow, besides from being connected 

to the set position through the commutator, is 

also proportional to the machine speed (posi-

tion of the accelerator pedal).

In this way, having to reduce the speed near 

curves or in presence of difficult areas, a 

useless water waste is avoided and simulta-

neously the drying is improved, because the 

squeegee picks up always the same solution 

quantity. 

When the commutator (B) is in OFF position, 

an auxiliary water system can be activated, 

that permits the traditional use of the machine 

and therefore the filling of the solution tank with 

water and detergent without using the system 

and therefore without the use of the pumps. 

In this case it is necessary to open and adjust 

manually a solution valve (C) placed un-der the 

machine. In this situation the push button (A) 

handles the command of the solenoid valve in 

manual function.

NOTE: at the end of each use of the machine 

in the traditional mode (without dosing system), 

to return to use the dosing system again, it 

is necessary to close the solution valve (C), 

otherwise the proportions water and detergent 

are not anymore the predetermined ones.

NOTE: if the automatic dosing system is not 

being used for a long time, it is possible that 

the hoses of the detergent circuit are emptied 

and therefore at the first use, the detergent 

begins to come out onto the brushes with a 

certain delay compared to the water outlet. 

Through the solution valve (D) it is possible to 

empty the detergent tank and to recover the 

detergent.

STARTING OF THE MACHINE

A safety device avoids the machine’s movement if the 

operator is not seated correctly on the guiding place.

To switch on the machine:

1. Sit on the guiding place.

2. Turn the key switch (24) clockwise to switch on the ma-

chine. Automatically, the machine gets ready in manual 

(MAN) mode and in forward movement with the quick 

speed (signal lamp 22).

3. Check the charge level of the batteries on the display 

(1).

4. Pressing the push button (5) the functioning of BREAK 

WASHING is chosen and the transfer operations of the 

machine are carried out (see under paragraph “FOR-

WARD AND BACKWARD MOVEMENT"). When the 

signal lamp (4) is on, then the machine is in BREAK 

WASHING mode.

5. Pressing the push button (6) the automatic (AUTO) 

functioning is chosen, while pressing the push button (3), 

the functioning of the machine becomes manual (MAN).

A. When the signal lamp (7) is on, the machine is 

functioning in automatic (AUTO) model and the machine 

activates and deactivates all the working functions in an 

automatic mode (see under paragraph “WORKING IN 

AUTOMATIC MODE”).

B. When the signal lamp (2) is on, the machine is 

functioning in manual (MAN) mode and it is possible to 

choose if:

I. to carry out the only transfer of the machine without 

activating or deactivating the working functions.

II. to activate separately only the controls relative to the 

washing function with the brushes (see under paragraph 

“WORKING IN MANUAL MODE”).

III. to activate separately only the controls relative to the 

drying function with the squeegee (see under paragraph 

“WORKING IN MANUAL MODE”).

ATTENTION:

In manual mode every function of the machine has to be 

activated or deactivated manually.

FORWARD AND BACKWARD MOVEMENT

It is recommended to carry out always the mere transfer 

of the machine in mode (BREAK WASHING).

To proceed to activate the movement of the machine:

1. Sit on the guiding place.

2. Turn the key switch (24) clockwise to switch on the 

machine.

3. Check the charge level of the batteries on the display 

(1). 

4. Pressing the push button (5) the functioning of BREAK 

WASHING is chosen to carry out the mere transfer of the 

machine. In fact, in this mode the washing functions of 

the machine are not working and only the traction system 

functions. When the signal lamp (4) is on, then the ma-

chine is in BREAK WASHING mode.

5. Check through the signal lamp (15) that the parking 

brake is not inserted and eventually release it (see under 

paragraph EMERGENCY-PARKING BRAKE”).

6.  Positioning the selector (28) forward, the forward 

drive is chosen, while positioning it back, the rear drive is 

chosen.
