Tornado BR 28/27, Operation & Maintenance Manual

11

The bending is not uniform

Adjust the squeegee inclination rotating counter-

clockwise the wing nut (7) to increase the bending 

in the central part, or clockwise to increase the 

bending on the extremities.

Height adjustment

Once that the pressure and inclination of the 

squeegee have been adjusted, it is necessary to 

fix this optimum condition making touch slightly 

the wheels onto the floor. Rotate counterclockwise 

the registers (8) to lower the wheels or clockwise 

to raise them. Both wheels must be adjusted in 

the same measure.

 ATTENTION:

Every type of floor requires a specific adjustment. 

For example, concrete floors (where the friction 

results to be high) need little pressure, while 

smooth floors (ceramics) need higher pressure.

If the cleaning operations are made always on the 

same type of floor, the adjustment can change 

only in function of the rubber wear.

ADJUSTMENT HEIGHT SIDE RUBBERS

To adjust the side rubbers, it is necessary to act 

upon the adjusting screws (1) and (2) after having 

loosened the upper blocking nuts. Unscrewing, 

the rubber lowers, while screwing down, the rub-

ber is lifted. The reason of the adjustment is to 

obtain an uniform bending.

Having finished the adjustment, tighten the block-

ing nuts to fix the position.

BRUSHES ASSEMBLY AND DISASSEMBLY

Normally, the machine is delivered with the 

brushes assembled. 

To assemble and disassemble the brushes on 

both sides of the machine:

1. Make sure the machine is switched off and with 

the brushes base in up position (lifted).

ATTENTION:

To carry out brushes assembly operations with 

the electric supply on, may cause damages to 

hands.

ATTENTION:

This operation must be carried out using gloves 

to protect from contact with dangerous solutions.

2. Unblock the bar of the side rubber after having 

released the knob (1).

3. Open the bar of the side rubber (2) as shown 

in the figure.

 4. Extract the support plate (3) of the brushes 

pulling it outwards by holding its handle.

5. Extract the brush (4).

6. During the reassembly of the brush (4), insert 

it into the brush base from the part where the 

seat is deeper (about 1.5” (40mm)). The opposite 

part with a depth of about .5” (13,5mm) has to 

look towards the support plate.

7. Place the support plate (3) into its position, then 

put back the bar of the side rubber (2) blocking it with 

the knob (1).

ATTENTION:

The brushes must be inserted easily without using 

tools in order not to damage or force them.

Use only brushes supplied with the machine or the 

ones indicated in the paragraph “RECOMMENDED 

BRUSHES”. The use of other brushes can compro-

mise the good washing result.

FLOOR CLEANING

RECOVERY TANK

Check that the cover of the suction filter (1) is cor-

rectly secured, after rotating the levers (2) and that 

the suction motor hose (3) is correctly connected to 

it.

Verify also that the squeegee hose couplings (4/5) 

are correctly inserted into their seats and that the 

exhaust hose plug (6) placed in the rear part of the 

machine is well closed.

DETERGENT SOLUTION TANK

The capacity of the detergent solution tank is indi-

cated in the technical data.

Open the screw plug placed in the left part of the ma-

chine and fill the detergent solution tank with clean 

water at a maximum temperature of 50°C (122°F). 

Add the liquid detergent in the percentage and condi-

tions foreseen by the manufacturer. To avoid exces-

sive foam presence, which could cause problems to 

the suction motor, use the minimum percentage of 

detergent. Screw down the plug to close the tank.
