3. Technical Information
3.1. General description
This machine is an automatic scrubber for sweeping, washing and drying at, horizontal, smooth or moderately
rough, even and obstacle free oors in civil and industrial premises.
The automatic scrubber spreads a solution of water and detergent in the correct concentration on the oor and
then scrubs it to remove the dirt. By carefully choosing the detergent and brushes / pads from the wide range
of accessories available, the machine can be adapted to a wide range of combinations of types of oor and dirt.
A suction system incorporated in the machine dries the oor after washing by means of the low pressure
generated in the dirty water drum by the suction motor. The squeegee connected to the recovery tank collects
the dirty water.
The machine is moved forward by:
Non-Traction drive: the auto scrubber is provided with a special mechanical drive device which exploits
the friction between the brush and the oor to generate a forward movement (for further details, see
paragraph 6.7).
Traction drive: the auto scrubber is moved forward by means of a special electromechanical drive device.

5. Fill the solution tank 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;
6. If the machine is tted with the optional CHEM DOSE accessory, remove the cap and ll the tank with
appropriately diluted low-foam detergent.
7. Mount the most suitable brushes / pads for the oor and work to be performed;
8. Make sure the squeegee is rmly attached and connected to the suction hose. Make sure the back
blade is not worn.
If you are using the machine for the rst time, we recommend trying it on a large obstacle-
free surface rst to acquire the necessary familiarity. Always empty the dirty water drum
before lling the detergent tank again.
Information
For eective 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 oors into parallel rectangular sections.
• If necessary, nish o by passing a mop or rag rapidly over parts inaccessible to the autoscrubber.
6.7. Working
After setting up the machine, proceed as follows:
1. Connect the machine as follows:
2. Move the tap lever (except 670 Eco) to the minimum detergent ow position. The detergent solution
starts owing to the brush;
3. Lower the squeegee by means of the corresponding lever;
4. Press the brush switch. For Eco machines, select the most suitable operating mode (BRUSH-PAD
mode with brush/abrasive disk or “MICROFIBRE” model with microbre disk) by holding the brush
switch down for at least 5 seconds;
5. Press the suction switch to start the suction motor;
6. Press the brush/drive lever;
Non-traction units:
• When the brush switch is in the “1” position 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 oor 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. If the machine pulls to the right, turn the knob clockwise and vice versa.

14
Traction units:
• To move forwards or backwards, see paragraph 6.3.
In both traction and non-traction units:
• Periodically check that the detergent is reaching the brushes / pads and rell when it runs out. When
there is no longer sucient water in the detergent tank, the level indicator lights up. Stop and ll the
tank;
• If the machine is tted with the optional CHEM DOSE accessory, press the button to turn the device
on, then adjust the detergent mixture to send to the brushes using the regulation screw found on the
front of the CHEM DOSE. The quantity can be adjusted from 0.5% to 3% per litre of water.
• During work check the cleaning quality and adjust the detergent ow to the brushes /pads by raising
or lowering the lever as required. When using the 400 Eco, the ow control lever must be completely
lowered (valve closed). When using the 670 Eco model, adjust the detergent ow by pressing the
button. The quantity of detergent delivered is indicated by the LEDs.
Pressure of the brush / microbre on the surface to the cleaned:
400 Eco: During work make sure the pressure of the microbre on the work surface is within the permitted
operating range. If the 3 green LEDs and the red LED come on during operation, brush pressure must be
reduced by turning the knob (ref. A). Turning it clockwise increases the pressure of the brushes on the work
surface, turning it counter-clockwise reduces the pressure of the brushes on the work surface. To access the
knob, lift the recovery tank.

670 Eco: Pressing the pad pressure button briey modies the pressure of the brushes / microbre on the
surface to be cleaned. The pressure exerted is indicated by the LEDs.
Important
Empty the recovery tank each time you ll the solution tank. Never leave the suction motor
on and detergent tap open when parked.
• When the recovery tank is full, the level indicator comes on and after a few seconds the suction motor
shuts o. You must stop working and empty the tank. To restart the suction motor, turn the suction
switch o and then on again.

15
At the end of work:
• Place the tap lever (except 400 Eco & 670 Eco) in the“CLOSED” position;
• Release the brush/drive lever located under the handgrip. This turns the brush/drive motor o and
the machine stops;
• Stop the brush / pad;
• Lift the lever to raise the squeegee from the oor to prevent the continuous pressure from warping
the blades;
• Let the suction motor run for at least 2 minutes to make sure it is completely dry, then press “0”
on the suction switch to switch o the suction motor;
• Remove the brushes (or drive pads) to prevent them from warping permanently;
• Press the button to turn the optional CHEM DOSE accessory o;
• Depending on the model, disconnect the ANDERSON connectors;
• Empty and clean the dirty recovery tank.
6.8. Some useful tips to get the most from your autoscrubber
In the event of particularly stubborn dirt on the oor, washing and drying can be performed in two separate
operations.
6.8.1. Prewashing using brushes or pads
1. Adjust the detergent ow, except 400 / 670 Eco machines;
2. Place the brush switch in position“1”;
3. Lower the head;
4. Operate the drive lever to rotate the brushes;
5. Make sure the suction motor is o and the squeegee is raised;
6. Begin washing.
The ow 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 mechanical action, detaching and suspending the dirt, and the brushes time to exert an
eective 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
Use suitable personal protection devices. Drain the dirty water with the machine
disconnected from the power supply.
Danger
The dirty recovery tank drain hose is at the back left side of the machine.
To empty the tank:

1. Move the machine near a drain;
2. Detach the drain hose (ref. 2) from its seat by holding it near the xing spring (ref. 3) and pulling horizontally;
3. Keeping the hose end as high as possible, unscrew and remove the cap (ref. 4);
4. Lower the hose end gradually, controlling the intensity of the ow of water by adjusting the height
from the ground;
5. 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;
6. When the dirty water has been totally drained, lower the dirty water drum (if previously lifted) and refasten
to the detergent tank;
7. Close the drain hose (ref. 2) by replacing the cap (ref. 4), check that it is tightly closed and replace
the hose in its housing.
Important
When washing the recovery tank, never remove the suction lter (ref. 2 below) from
its housing and never direct the jet of water against the lter itself.

from the power supply.
Danger
To empty the tank:
1. Move the machine near a drain;
2. Unclip the drain hose from the lower right hand backside of the machine;
3. When the solution tank is completely empty, replace the cap.
The water and detergent solution can also be used to wash the recovery tank or software.
Information
7. Periods Of Inactivity
If the machine is not used for some time, remove the squeegee and brushes / pads, wash them and put them
away in a dry place (preferably in a bag or wrapped in plastic lm) 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 (disconnect the ANDERSON connector from the battery
wiring).
Batteries: Completely recharge the batteries before storing them. During long periods of inactivity, you should
charge the batteries regularly (at least once every two months) to keep them constantly at maximum charge.
8. Battery Maintenance And Charging
See appropriate Dustbane literature for specics on battery maintenance and charging.
9. Maintenance Instructions
Never perform any maintenance operations without rst disconnecting the batteries.
Maintenance on the electrical circuit and all other operations not explicitly described
in this manual must be performed by specialised personnel only, in compliance with current
safety legislation and as described in the maintenance manual.
Danger
9.1. Maintenance - General rules

9.2.4 Squeegee blades: replacing
The squeegee blades collect the lm of water and detergent from the oor and prepare the way for perfect
drying. With time, the constant rubbing leaves the edge of the blade in contact with the oor rounded and
cracked, reducing the drying eciency and requiring it to be replaced.
Turning or replacing the squeegee blades:
