3.1. General description

This machine is a scrubber drier for sweeping, washing and drying flat, horizontal, smooth or moderately rough, even and obstacle free floors in civil and industrial premises. It is available in both battery and cable versions to meet all running time and weight requirements. The scrubber drier spreads a solution of water and detergent in the correct concentration on the floor and then scrubs it to remove the dirt. By carefully choosing the detergent and brushes (abrasive disks or rollers) from the wide range of accessories available, the machine can be adapted to a wide range of combinations of types of floor and dirt. A suction system incorporated in the machine dries the floor after washing by means of the low pressure generated in the dirty water tank by the suction motor. The squeegee connected to the tank collects the dirty water. The machine is moved forward by:

MODEL B mechanical drive: the scrubber drier is provided with a special mechanical drive device which exploits the friction between the brush and the floor to generate a forward movement (for further details, see paragraph 6.7).

MODEL BT electric drive: the scrubber drier is moved forward by means of a special electromechanical drive device.

PRACTICAL GUIDE FOR THE OPERATOR

ENGLISH

• Dirty water drum level indicator (fig. 5, ref. 4): when the dirty water drum is full the LED

comes on and after a few seconds the suction motor shuts down.

• Display: displays any alarms active. During normal operation, it displays the hour

counter (giving the actual number of hours the machine has been operating).

• Direction selection (fig. 5, ref. 13 - BT models with electric drive): sets movement of

the machine to forwards or reverse.

• Speed control potentiometer (fig. 5, ref. 11 - BT models with electric drive),

turning the potentiometer sets the maximum machine speed.

6.2. Mounting and adjusting the squeegee

The squeegee (fig. 6) is responsible for the first phase of drying. To mount the squeegee on the machine, proceed as follows:

• check that the squeegee mount (fig. 6, ref. 2) is raised, otherwise lift it by means of the

squeegee lever (fig. 5, ref. 8);

• insert the suction hose sleeve (fig. 6, ref. 4) fully into the squeegee;

• slacken the two knobs (fig. 6, ref. 3) at the centre of the squeegee;

• insert the two threaded pins into the slots on the support (fig. 6, ref. 2);

• fix the squeegee by tightening the two knobs (fig. 6, ref. 3).

The squeegee blades scrape the film of water and detergent from the floor and prepare the way for perfect drying. With time, the constant rubbing makes the edge of the blade in contact with the floor rounded and cracked, reducing the drying efficiency and requiring it to be replaced. The state of wear should be checked frequently. For perfect drying, the squeegee must be adjusted in such a way that the edge of the rear blade bends during operation by about 45° with respect to the floor at every point. The angle of the blades can be adjusted using the screw (fig. 6, ref. 1), while the height of the squeegee from the floor can be adjusted using the screw (fig. 6, ref. 5).

6.3. Moving the machine when not in operation

Proceed as follows to move the machine.

• raise the squeegee;

• push the head pedal down then to the right (fig. 5 ref. 9) to raise the head;

• move the machine as follows:

• Versions with mechanical drive: push or pull;

• Versions with electric drive: to move the machine forwards, press the selector

(fig. 5 ref. 13), then operate the drive lever (fig. 5 ref. 7). To move the machine backwards, press the selector (fig. 5 ref. 13), then operate the drive lever (fig. 5. ref. 7); speed can be varied by the potentiometer knob (fig. 5. ref. 11).

• once you have reached your destination, lower the head by pressing the release pedal

(fig. 5 ref. 9) down and to the left, then release it.

These operations must be performed with the machine off.

Fitting the brushes (two brush models):

Raise the machine head by pushing the head lift pedal down and then to the right (fig. 5, ref. 9). Place the brushes under the head drive disk. Lift the right brush with your hands and turn it clockwise, locking it in position on the drive disk. Lift the left brush with your hands and turn it anticlockwise, locking it in position on the drive disk. Use of abrasive disks: fit the abrasive disk on the drive disk and perform the operations described for fitting the brush on the scrubber drier.

Removing the brushes (two-brush models): Raise the machine head by pushing the head lift pedal down and then to the right (fig. 5, ref. 9). Turn the right brush anticlockwise, releasing it from the drive disk. Turn the left brush clockwise, releasing it from the drive disk.

6.5. Detergents - Instructions

IMPORTANT



Always dilute the detergent according to the manufacturer's instructions. Do not

use sodium hypochlorite (bleach) or other oxidants, particularly in strong

concentrations. Do not use solvents or hydrocarbons. The temperature of the water

and detergent must not exceed the maximum indicated in the technical

specification. They must be free of sand and/or other impurities.

The machine has been designed for use with low-foam biodegradable detergents made specifically for scrubber driers. For a complete and up-to-date list of the detergents and chemicals available, contact the Manufacturer: Use products suitable for the floor and dirt to be removed only. Follow the safety regulations on use of detergents given in the section "Safety regulations".

6.6. Preparing the machine for work

IMPORTANT



Before starting work, wear overalls, ear protectors, non-slip waterproof shoes,

mask to protect the respiratory tract, gloves and all other personal protection

devices recommended by the supplier of the detergent used or necessitated by the

work environment.

Proceed as follows before starting work.

• check the battery charge (recharge if necessary);

• lower the head by means of the pedal (fig. 5, ref. 9);

ENGLISH

• make sure the dirty water drum (fig. 2, ref. 2) is empty. If necessary, empty it;

• via the opening at the front, fill the detergent tank (fig. 2, ref. 7) with a suitable

concentration of clean water and low-foam detergent. Leave at least 5 cm between the surface of the liquid and the opening of the tank;

• if the machine is fitted with the optional CHEM DOSE accessory, remove the cap (fig.

13, ref. 1) and fill the tank with appropriately diluted low-foam detergent.

• mount the most suitable brushes, drive disks or rollers for the floor and work to be

performed (see paragraph 3.4);

• make sure the squeegee (fig. 2, ref. 6) is firmly attached and connected to the suction

hose (fig. 6, ref. 4). Make sure the back blade is not worn.

i INFORMATION

If you are using the machine for the first time, we recommend trying it out on a

large obstacle-free surface first to acquire the necessary familiarity.

Always empty the dirty water tank before filling the detergent tank again.

For effective cleaning and to extend the working life of the machine, follow a few simple rules:

• prepare the work area by removing all possible obstacles;

• begin working from the furthermost point to avoid walking on the area you have just

cleaned;

• choose the straightest possible working routes;

• divide large floors into parallel rectangular sections.

If necessary, finish off by passing a mop or rag rapidly over parts inaccessible to the scrubber drier.

6.7. Working

After setting up the machine, proceed as follows:

• lower the squeegee by means of the corresponding lever (fig. 5, ref. 8);

• press the brush button (fig. 5, ref. 3) (LED on), the suction motor starts up

automatically;

• press the suction button (fig. 5, ref. 2) if you want to disable detergent suction;

• press the brush/drive lever (fig. 5, ref. 7);

• Models with mechanical drive: When the brush motor is enabled and the drive lever is

pulled, the motor which turns the brush and moves the machine starts up. A special mechanical drive device uses the friction between the brush and floor to generate a forward movement. When the mechanical drive lever is released, the brush motor shuts down and the machine stops. If the machine pulls to one side, restore a straight course by using the direction regulation knob (fig. 5, ref. 10). If the machine pulls to the right, turn the knob clockwise and vice versa.

• Models with electric drive: to move forwards or backwards, see paragraph 6.3.

periodically check that the detergent is reaching the brushes and refill when it runs out. When there is no longer sufficient water in the detergent tank, the level indicator lights up (fig. 5, ref. 5). Stop and fill the tank; If the machine is fitted with the optional CHEM DOSE accessory, press the button (fig. 13, ref. 2) to turn the device on, then adjust the detergent mixture to send to the brushes using the regulation screw (fig. 13, ref. 3). The quantity can be adjusted from 0.5% to 3% per litre of water.

when working, check cleaning quality and if necessary adjust the flow of detergent by pressing the button (fig. 5, ref. 18); the amount of liquid delivered is indicated by the LEDs (fig. 5, ref. 20).

IMPORTANT



Empty the dirty water tank each time you fill the detergent tank.

Never leave the suction motor on and detergent tap open when parked.

ENGLISH

• when the dirty water drum is full, the level indicator comes on (fig. 5, ref. 4) and after a

few seconds the suction motor shuts off. You must stop working and empty the tank.

• if the warning LED (fig. 5, ref. 1) starts flashing, it means that the batteries are almost

flat. After a few seconds the brushes shut down to prevent excessive discharge of the batteries. Charge the batteries.

At the end of work:

• release the brush/drive lever (fig. 5, ref. 7) located under the handgrip. This turns the

brush/drive motor off and the machine stops;

• stop the brush by pressing the button (fig. 5, ref. 3);

• lift the lever (fig. 5, ref. 8) to raise the squeegee from the floor to prevent the continuous

pressure from warping the blades;

• remove the brushes (or drive disks) to prevent them from warping permanently;

• press the button to turn the optional CHEM DOSE accessory off (fig. 13, ref. 2);

• empty and clean the dirty water tank.

6.8. Some useful tips to get the most from your scrubber drier

•

In the event of particularly stubborn dirt on the floor, washing and drying can be performed in two separate operations.

6.8.1. Prewashing with brushes or pads

• adjust detergent flow;

• press the brush button (fig. 5, ref. 3)

• lower the head;

• operate the drive lever to rotate the brushes;

• make sure the suction motor is off and the squeegee is raised;

• begin washing.

The flow of water must be adjusted in proportion to the desired advance speed. The slower the machine moves forwards, the less water is needed. Persist when washing particularly dirty points to give the detergent time to perform its chemical action detaching and suspending the dirt and the brushes time to exert an effective mechanical action.

6.8.2. Drying

Lower the squeegee and with the suction motor on, pass over the same area washed previously. The result is equivalent to in-depth washing and subsequent ordinary maintenance will take less time. To wash and dry at the same time, operate the brush, water, squeegee and suction motor simultaneously.

6.9. Draining the dirty water

! DANGER

Use suitable personal protection devices.

Drain the water with the machine disconnected from the power supply.

The dirty water drum drain hose is at the back left side of the machine. To empty the tank:

• move the machine near a drain;

• detach the drain hose (fig. 7, ref. 2) from its seat by holding it near the fixing spring (fig.

7, ref. 3) and pulling horizontally;

• keeping the hose end as high as possible, unscrew and remove the cap (fig. 7, ref. 4);

• lower the end of the hose gradually, controlling the intensity of the flow of water by

adjusting the height from the ground;

ENGLISH

• check the amount of dirt left in the dirty water drum and if necessary wash it out. To

facilitate cleaning and complete emptying of the drum, you are recommended to unfasten and lift it;

• when the dirty water has been totally drained, lower the dirty water drum (if previously

lifted) and refasten to the detergent tank;

• close the drain hose (fig. 7, ref. 2) by replacing the cap (fig. 7, ref. 4), check that it is

tightly closed and replace the hose in its housing.

IMPORTANT



When washing the dirty water drum, never remove the suction filter (fig. 9, ref. 2)

from its housing and never direct the jet of water against the filter itself.

You are then ready to wash and dry again.

6.10. Draining the clean water

! DANGER

Use suitable personal protection devices.

To empty the tank:

• move the machine near a drain;

• remove the cap (fig. 8, ref. 1);

• when the detergent tank is completely empty, replace the cap (fig. 8, ref. 1).

i INFORMATION

The water and detergent solution can also be used to wash the dirty water tank.

If the machine is not used for some time, remove the squeegee and brushes (or drive disks), wash them and put them away in a dry place (preferably in a bag or wrapped in plastic film) away from dust. Park the machine with the head lowered. Make sure the tanks are completely empty and perfectly clean. Disconnect the machine from the power supply. Completely recharge the batteries and deposit them in the battery store. During long periods of inactivity, you should charge the batteries regularly (at least once every two months) to keep them constantly at maximum charge.

If you do not charge the batteries regularly, they may be irreparably damaged.
