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.
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 (or abrasive disks) 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.
3.2. Legend
The main parts of the machine are as follows:
• detergent tank (fig. A, ref. 1): contains and transports the mixture of clean water and
detergent;
• dirty water tank (fig. A, ref. 2): collects the dirty water picked up from the floor after
washing;
• control panel (fig. A, ref. 3);
• head assembly (fig. A, ref. 4): the main element is the brushes which distribute the
detergent solution on the floor and remove the dirt;
• squeegee assembly (fig. A, ref. 5): wipes and dries the floor by collecting the water;
3.3. Danger zones
A - Tank assembly: when using certain detergents, danger of irritation for eyes, skin,
mucous membranes and respiratory tract and of asphyxia. Danger represented by

functions. To start up the machine, turn the key clockwise.
• Emergency button (fig. B, ref. 7): this acts as a safety device
. To stop the machine
press the button.
Page 13
ENGLISH
13
• Brush button (MANUAL OPERATION) (fig. B, ref. 8): enables (LED on) and disables
(LED off) brush operation and head raising and lowering.
• Suction button (MANUAL OPERATION) (fig. B, ref. 9): starts and stops the suction
motor responsible for drying the floor being washed. When the suction motor is
turned on, the squeegee is automatically lowered. When it is turned off, the squeegee
is automatically raised.
• Detergent flow regulation buttons (fig. B, ref. 5): pressing these buttons regulates
the quantity of detergent delivered (displayed by LEDs).
• Detergent tank level indicator (fig. B, ref. 10): the LED comes on when there is no
longer sufficient water in the detergent tank.
• Dirty water tank level indicator (fig. B, ref. 11): when the dirty water tank is full the
LED comes on and after a few seconds the suction motor shuts down.
• Direction selector (fig. B, ref. 12): move this selector to set movement of the machine
to forwards or reverse
• Alarm indicator (fig. B, ref. 13), the frequency with which the LED lights up defines
the electronic board error code (see chapter 11). During operation in the absence of
malfunction, the LED is on steadily.
• Horn (fig. B, ref. 14): acoustic warning.
• Settings button (fig. B, ref. 4): when pressed, scrolls through the various parameters
which can be set on the machine software.
• Work programme buttons (AUTOMATIC OPERATION): set the work programme to
be used.
1. P1 (fig. B, ref. 1) light wash programme for smooth not excessively dirty floors.
2. P2 (fig. B, ref. 15) medium wash programme for smooth floors with evident
dirt.
3. P3 (fig. B, ref. 2) heavy wash programme for rough floors (concrete etc.) with
stubborn dirt.
Please note: before setting a new work programme, the previous programme
must be deselected.
• Brush attachment/release button (fig. B, ref. 16): enables automatic brush
attachment or release
• CHEM DOSE switch (optional) (fig. B, ref. 17): enables and disables CHEM DOSE
operation
• Service brake/parking brake (fig. D, ref. 1), acts mechanically on the two drum
brakes on the rear wheels.
• Machine movement pedal (fig. D, ref. 2): pivoting device to regulate machine speed.
• Side brush lifting levers (fig R, ref. 1): raising or lowering these levers disables or
enables operation of the side brushes (when present).
• Speed potentiometer (fig. B, ref. 18): regulates the speed of the machine forwards
and backwards.
i INFORMATION
The machine (CT 230 only) has a safety system to prevent it tipping over. This
reduces the speed on bends, irrespective of the pressure exerted on the machine
movement pedal. This reduction of speed on bends is therefore not a malfunction,
but a feature which increases the machine's stability in all conditions.
Page 14

6.2. Mounting and adjusting the squeegee
The squeegee (fig. E) is responsible for the first phase of drying.
To mount the squeegee on the machine, proceed as follows:
• make sure the squeegee mount (fig. E, ref. 1) is raised;
• insert the sleeve of the suction hose (fig. E, ref. 2) fully into the squeegee;
• slacken the two knobs (fig. E, ref. 3) at the centre of the squeegee;
• insert the two threaded pins into the slots on the support;
• fix the squeegee by tightening the two knobs (fig. E, 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 during work by turning the knob (fig. E, ref.
5) on the squeegee mount. The height of the squeegee can be adjusted by adjusting
the height of the wheels on the squeegee mount (fig. E, ref. 4).
6.3. Moving the machine when not in operation
To move the machine, proceed as follows:
• raise the squeegee;
• raise the head;
• use the selector (fig. B, ref. 12) to set the direction of movement;
• operate the accelerator pedal (fig. D, ref. 2).
IMPORTANT
Do not leave the machine unattended or parked with the key inserted in the main
switch and the parking brake off.
6.4. Mounting and changing the brush/drive disks
IMPORTANT
Never work without the brushes and drive disks correctly installed.
Automatic brush attachment: with the head raised and the machine off, lift the side
flaps on both sides (fig. F, ref. 1) and place the brushes under the head, making sure they

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.
Before starting work, proceed as follows:
• check the battery charge (charge if necessary);
• make sure the dirty water tank (fig. A, ref. 2) is empty. If necessary, empty it;
• via the opening, fill the detergent tank (fig. A, ref. 1) 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, fill the CHEM DOSE
tank (fig. G, ref. 2) with appropriately diluted low-foam detergent.
• mount the most suitable brushes or drive disks for the floor and work to be performed
(see paragraph 3.4);
• make sure the squeegee (fig. E) is firmly attached and connected to the suction hose
(fig. E, ref. 2). Make sure the back blade is not worn.
i INFORMATION
If you are using the machine for the first time, we recommend trying it 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:
Page 16
ENGLISH
16
• 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
i INFORMATION
The seat (fig. D, ref. 3) has a safety sensor which allows the machine to move only
when the operator is seated.
i INFORMATION
The machine (CT 230 only) has a safety system to prevent it tipping over. This
reduces the speed on bends, irrespective of the pressure exerted on the machine
movement pedal. This reduction of speed on bends is therefore not a malfunction,
but a feature which increases the machine's stability in all conditions.
i INFORMATION
When the machine movement pedal is released, all functions shut down
automatically within 5 seconds (Auto Power-Off). While the machine is in stand-by,
the light corresponding to the set programme will flash. To reactivate the
functions, just move the machine without deselecting the set programme (Auto
Power-On).
After setting up the machine, proceed as follows:
• start the machine by turning the key (main switch) clockwise (fig. B, ref. 3).
• Select the most suitable programme from the three available. Pressing one of the work
programme buttons activates all the functions of the chosen programme (brush motors
and suction motor on).
• P1 (fig. B, ref. 1) light wash programme for smooth not excessively dirty floors.
• P2 (fig. B, ref. 15) medium wash programme for smooth floors with evident dirt.
• P3 (fig. B, ref. 2) heavy wash programme for rough floors (concrete etc.) with
stubborn dirt.
• Press the detergent flow regulation buttons (fig. B, ref. 5): to set the quantity of
detergent delivered (displayed by LEDs).
• use the direction selector (fig. B, ref. 12) to set the direction of movement;
• press the machine movement pedal (fig. D, ref. 2).
• the maximum working speed can be set by turning the speed potentiometer (fig. B, ref.
18).
• If the machine is fitted with side brushes, these must be lowered using the levers on
the steering column. The brush motors will not start unless the brushes are fully
lowered (fig. R, ref. 1).
• Begin working.
•
• If the machine is fitted with the optional CHEM DOSE accessory, press the button (fig.
B, ref. 17) to turn the device on, then adjust the detergent mixture to send to the
Page 17
ENGLISH
17
brushes using the regulation screw (fig. G, ref. 1). The quantity can be adjusted from
0.5% to 3% per litre of water.
IMPORTANT
Empty the dirty water tank each time you fill the detergent tank.
• when the dirty water tank is full, the corresponding level indicator comes on (fig. B, ref.
11) and after a few seconds the suction motor shuts down. You must stop working and
empty the tank.
• when the detergent tank is empty, the corresponding level indicator comes on (fig. B,
ref. 10), the machine emits an intermittent beep and "water reserve" is displayed. You
must stop work and fill the detergent tank.
• The machine has a safety device which automatically disables all functions, apart from
the drive, when the batteries drop below about 29 V. You must charge the batteries.
At the end of work:
• Disable the chosen wash programme (fig. B, ref. 1,2,15 (LED off);
• release the machine movement pedal (fig. D, ref. 2)
• turn the optional CHEM DOSE accessory off (fig. B, ref. 17);
• put the parking brake (fig. D, ref. 1) on;
• stop the machine by turning the key (main switch) anticlockwise (fig. B, ref. 3).
• disconnect the batteries;
• empty and clean the dirty water tank using the drain hose (fig. H, ref. 1).
• empty and clean the debris bin, ROLLER head version (fig. S, ref 5).
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
• start the machine by turning the key (main switch) clockwise (fig. B, ref. 3).
• adjust the detergent flow (fig. B, ref. 5);
• press the brush button (fig. B, ref. 8) (LED on);
• stop the suction motor by pressing the button (fig. B, ref. 9) (LED off);
• If the machine is fitted with the optional CHEM DOSE accessory, press the button (fig.
B, ref. 17) to turn the device on, then adjust the detergent mixture to send to the
brushes using the regulation screw (fig. G, ref. 1). The quantity can be adjusted from
0.5% to 3% per litre of water.
• 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
Turn the suction motor on by pressing the button (fig. B, ref. 9), then pass over the same
area washed previously. The result is equivalent to in-depth washing and subsequent
ordinary maintenance will take less time.
6.9. Draining the dirty water
! DANGER
Page 18
ENGLISH
18
Use suitable personal protection devices.
The dirty water tank drain hose is at the back of the machine on the right.

Motor drive alarm board
If the machine drive stops, control the status LED (fig. B, ref. 13) to identify the error code. In the
absence of malfunctions, the status LED is lit steadily while the machine is in operation. If a
malfunction is detected, the status LED provides two types of information, a slow flash (2 Hz) or a
rapid flash (4 Hz) to indicate the severity of the malfunction.
Malfunctions with a slow flash are cancelled automatically once the malfunction has been repaired
and the machine functions normally again. Malfunctions with a rapid flash ("*" in the table) are
considered more serious. The machine must be turned of using the key switch (fig. B ref. 3) to reset
