Tornado BR 28/27, Operation & Maintenance Manual

14

TO CARRY OUT THE FUNCTION OF ONLY 

DRYING:

1. Press the push button (11) of up/down squee-

gee to lower the squeegee. The signal lamp (12) 

indicates that the squeegee is lowering or lifting.

2. Press the switch (9) of the suction motor to 

start the suction system. The signal lamp (8) 

indicates that the machine is drying.

Position the selector (28) forward to choose the 

forward drive.

Adjust the movement speed in forward with the 

push button (21) (see under paragraph "FOR-

WARD AND BACKWARD MOVEMENT”).

Pressing the accelerator pedal, the machine 

begins to proceed forward and to work according 

to the set functions.

ATTENTION:

In manual mode every function of the machine 

has to be activated or deactivated manually.

WORKING ADJUSTMENTS

Both in automatic as in manual mode, during the 

first metres check:

1. that the squeegee adjustment guarantees a 

perfect drying result (see under paragraph “AD-

JUSTMENT 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 AD-

JUSTMENT 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 act 

upon the solution valve knob (27) placed on the 

right of the steering column, rotating counterclock-

wise to increase it and clockwise to reduce it up 

to close the flow.

ADJUSTMENT OF THE BRUSHES PRESSURE

Both in automatic as in manual mode it is 

possible through the knob (10) to adjust the 

brushes pressure on the floor in eight established 

levels. During the operation, we can visualize on 

the display (1) the value in per percentage of the 

electric absorption of the brushes motor by press-

ing the button (14). 

The adjustment in this mode is done both in auto-

matic and manual operation.

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 presence on the display (1) of a blinking 

warning from P2 to P8 indicates that the pressure 

level set  determines 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 

”AL01” to “AL20”.

ATTENTION:

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.

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. The machines equipped with electric 

float (optional), the switching off of the suction 

motor and its signal lamp (12) happens in auto-

matic mode. 

When this happens, it is necessary to empty the 

recovery tank (see under paragraph “RECOVERY 

TANK EMPTYING AND CLEANING”).

STOP OF THE MACHINE AFTER CLEANING 

OPERATION

IN AUTOMATIC OR MANUAL WORKING 

MODE:

1. A the end of the washing cycle, pressing 

the push button (5), the functioning of BREAK 

WASHING is chosen. When the signal lamp (4) is 

on, then the machine is in the functioning mode 

BREAK WASHING. In this way automatically the 

solenoid valve shuts down, the brushes are lifted 

slightly (a few millimeters) continuing to turn for 

about 10 seconds (drying phase of the brushes) 

and the collection box drains the exceeding water 

to the floor; then, the washing group lifts com-

pletely while the squeegee continues to remain in 

working position with the suction motor on, after 

5 seconds the squeegee lifts and when it reaches 

the highest position, also the suction motor stops, 

with a delay of another 5 seconds. 

NOTE: all these phases are carried out with 

the machine operating, so that the squeegee 

can dry the interested cleaning area from the 

“drying phase of the brushes” and further-

more can dry the suction hose of its dirty wa-

ter.  At any time it is possible to interrupt the 

proce-dure BREAK WASHING by stopping the 

drive.

2. During the phase of BREAK WASHING, when 

the accelerator pedal is released for more than 3 

seconds, the squeegee raises itself and the 

suction switches off automati-cally.

3. After three seconds, the accelerator can be 

pressed again, if a machine's transfer has to be 

made (you can anyway make the transfer even if 

the pedal is not lifted once that 20 seconds have 

passed).

4. Turn the switch key counterclockwise to switch 

off the machine.

5. Insert the parking brake (see under paragraph 

“EMERGENCY-PARKING BRAKE”).

ATTENTION:

The mode (BREAK WASHING) is specific for the 

transfer at the end of the cleaning operation.

Starting again the cleaning operation:

A. by pressing the push button (6) the automatic 

(AUTO) functioning is chosen to start working in 

automatic mode.
