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 (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 (fig. A):
•the detergent tank (fig. A, ref. 1): contains and transports the mixture of clean water
and detergent;
•the 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 brush which distributes 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
the dirt collected from the environment (germs and chemical substances). Danger of
crushing between the two tanks when the dirty water tank is replaced on top of the
detergent tank.
B - Control panel: danger of short circuit.

!DANGER
Failure to observe these instructions could cause possibly serious damage to people
and things and invalidates the guarantee.
5.5. Power supply batteries (battery models)
Two different types of battery may be installed on these machines:
•tubular leak-proof batteries: the electrolyte level must be checked regularly. When
necessary, top up with distilled water until the plates are covered. Do not over fill (5
mm max. above the plates).
•gel batteries: this type of battery requires no maintenance.
The technical characteristics must correspond to those indicated in the paragraph on the
technical specification of the machine. The use of heavier batteries could seriously
jeopardise manoeuvrability and lead to the brush motor overheating. Batteries with a
lower capacity and weight will require charging more frequently.
They must be kept charged, dry and clean and the connections must be tight.
5.5.1. Batteries: preparation
!DANGER
During installation of the batteries or any type of battery maintenance, the operator
must be provided with the necessary personal protection devices (gloves, goggles
overalls, etc) to limit the risk of accident. Keep away from naked flames, avoid
short circuiting the battery poles, avoid sparks and do not smoke.
The batteries are normally supplied filled with acid and ready for use.
If the batteries are dry, before mounting them on the machine, proceed as follows:
• remove the caps and fill all elements with specific sulphuric acid solution until the
plates are entirely covered (this requires at least a couple of passes for each element);
• leave for 4-5 hours to allow the air bubbles to come to the surface and the plates to
absorb the electrolyte;
• make sure the level of electrolyte is still above the plates and if necessary top up with
sulphuric acid solution;
• close the caps;
• mount the batteries on the machine (following the procedure described below).
Before starting up the machine for the first time, charge the batteries as follows.
5.5.2. Batteries: installation and connection

6. PRACTICAL GUIDE FOR THE OPERATOR
6.1. Controls - Description
With reference to fig. C, the machine has the following controls and indicator lights:
•Power on light (fig. C, ref. 7 - cable model only): green, indicates that the machine's
power cable is connected to the mains.
•Battery charge light (fig. C, ref. 2 - battery models only): 3 LEDs (red, yellow and
green) which indicate the level of battery charge. There may be:
a) red, yellow and green LEDs on: battery voltage >24V;
b) red and yellow LEDs on: battery voltage <24V;
c) red LEDs on: battery voltage <23V;
d) red LED flashing: battery voltage <21.5V, batteries completely flat; after a few
seconds the brush and suction motor shut down;
•Main Switch (fig. C, ref. 3): enables and disables electrical power to all machine
functions (to turn the machine off, hold the button down for at least 4 seconds).
•Brush button with light (fig. C, ref. 4): enables (LED on) and disables (LED off) the
"brush" function. The brush does not start rotating until the brush lever is operated.
•Suction button with light (fig. C, ref. 5): turns the suction motor on (LED on) and off
(LED off) to dry the floor being washed. The light is on when there is power to the
suction motor.
•Detergent button (fig. C, ref. 6): enables (LED on) and disables (LED off) detergent
flow. The detergent does not flow unless the brush is rotating.
•Brush lever (fig. D, ref. 1): enables brush rotation.
•Squeegee lever (fig. D, ref. 2): raises (if lowered) or lowers (if raised) the squeegee.
•Handle regulation lever (fig. D, ref. 3): allows the angle of the handle to be adjusted.
6.2. Mounting and adjusting the squeegee
The squeegee (fig. A, ref. 5) is responsible for the first phase of drying.
To mount the squeegee on the machine, proceed as follows:
1) check that the squeegee mount (fig. E, ref. 1) is lowered, otherwise lower it by means
of the squeegee lever (fig. D, ref. 2);
2) rotate the machine backwards and rest the handle on the floor;
3) insert the two threaded pins on the squeegee into the slots on the support (fig. E, ref.
1);
4) fix the squeegee by tightening the two knobs (fig. E, ref. 2);

ENGLISH
13
5) insert the sleeve of the suction hose (fig. E, ref. 4) fully into the squeegee;
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. Adjust
the height of the blade during operation by regulating the height of the wheels positioned
behind and alongside the squeegee (fig. E ref. 3).
6.3. Moving the machine when not in operation
To move the machine, proceed as follows:
•lift the squeegee using the squeegee lever (fig. D, ref. 2);
•raise the front of the machine by levering on the handle and move it to the destination.
•on arrival, lower the front of the machine.
6.4. Mounting and changing the brush/drive disks
IMPORTANT
Never work without the brushes and drive disks correctly installed.
Brush attachment: turn the machine on by pressing the main switch (fig. C, ref. 3) (LED
on), then press the brush button (fig. C, ref. 4 (LED on). Rest the brush on the floor in
front of the machine. Raise the front of the machine by levering on the handle, then lower
it onto the brush, centring it with the brush cover. Operate the brush lever (fig. D, ref. 1)
repeatedly until the brush automatically engages on the flange hub. If the manoeuvre is
not successful, press on the handle again and repeat the centring and repeated operation
of the brush lever.
Brush release: turn the machine on by pressing the main switch (fig. C, ref. 3) (LED on),
then press the brush button (fig. C, ref. 4 (LED on).
Raise the front of the machine by levering on the handle, then operate the brush lever
(fig. D, ref. 1) repeatedly. After a few pulses, the brush (or drive disk) is released and
falls to the ground.
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.

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
•press the main switch (fig. C, ref. 3) (LED on);
•press the brush button (fig. C, ref. 4) (LED on);
•press the suction button (fig. C, ref. 5) (LED off) to turn suction off;
•operate the brush lever (fig. D, ref. 1) to enable brush rotation;
•make sure the suction motor is off and the squeegee is raised;
•begin washing.
•adjust the flow of detergent to the brush by means of the detergent tap (fig. G, ref. 2).
Flow speed must be regulated according to the operator's chosen 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, detergent flow, 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 tank drain hose is at the back of the machine on the right.
To empty the tank:
•move the machine near a drain;
•detach the drain hose (fig. A, ref. 7) from its seat by holding it near the fixing spring and
pulling horizontally;
•keeping the end of the hose as high as possible and remove the cap;
•lower the end of the hose gradually, controlling the intensity of the flow of water by
adjusting the height from the ground;
•check the amount of dirt left in the dirty water tank and if necessary wash it out;

ENGLISH
16
•close the drain hose with the cap. Check that it is tightly closed and replace the hose in
its housing.
•You are then ready to wash and dry again.
6.10. Draining the clean water
!DANGER
Use suitable personal protection devices.
Drain the water with the machine disconnected from the power supply.
To empty the tank:
•move the machine near a drain;
•remove the cap (fig. G, ref. 1);
•when the detergent tank is completely empty, replace the cap (fig. G, ref. 1).
i INFORMATION
The water and detergent solution can also be used to wash the dirty water tank.
7. PERIODS OF INACTIVITY
If the machine is not used for some time, remove the squeegee and brush (or drive disk),
wash them and put them away in a dry place (preferably in a bag or wrapped in plastic
film) away from dust.
Make sure the tanks are completely empty and perfectly clean.
Disconnect the machine from the power supply (depending on the model, unplug from the
mains or disconnect the connector from the battery wiring).
Battery models: charge the batteries completely 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.


IMPORTANT
If you do not charge the batteries regularly, they may be irrevocably damaged.
8. BATTERY MAINTENANCE AND CHARGING
!DANGER
Do not check the batteries by sparking.
The batteries give off flammable fumes. Put out all fires and hot embers before
checking or topping up the batteries.
Perform the operations described above in a ventilated room.
To avoid permanent damage to the batteries, do not run them down completely.
Remember that when the corresponding red light (fig. C, ref. 2) flashes on the control
panel, you must charge the batteries.
8.1. Charging procedure
•if the machine does not have an on-board charger, connect the external battery charger
connector to the battery wiring connector.
•if the machine has an on-board battery charger, connect the on-board battery charger
power cable (fig. H, ref. 1).

ENGLISH



IMPORTANT
In the case of gel batteries, use a charger specific for gel batteries only.
•Charge the batteries as described in the battery charger manual;
•at the end of charging, disconnect the connectors;
•reconnect the battery wiring connector to the machine connector (machine with external
battery charger).
9. MAINTENANCE INSTRUCTIONS
!DANGER
Never perform any maintenance operations without first unplugging the machine
from the mains (cable version) or disconnecting the batteries.
In cable models, the operator must be able to verify from any position that the
machine remains unplugged from the mains socket while maintenance is being
carried out.
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.
9.1. Maintenance - General rules
Performing regular maintenance according to the Manufacturer's instructions improves
performance and extends the working life of the machine.
When cleaning the machine, respect the following:
•avoid the use of high pressure washers. Water could penetrate the electrical
compartment or motors leading to damage or the risk of short circuit;
•do not use steam to avoid the heat warping plastic parts;
•do not use hydrocarbons or solvents as they could damage the cowling and rubber
parts.
9.2. Routine maintenance
9.2.1 Float switch: cleaning
•Remove the dirty water tank cap and clean the float switch (fig. I, ref. 1). Make sure it
runs freely on the pin.
•clean the detergent tank filter (CT30 ONLY) (fig. N).
9.2.2 Squeegee blades: replacing
The squeegee blades collect 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.
Turning or replacing the blades:
•lower the squeegee by means of the squeegee lever (fig. D, ref. 2);
•tip the machine backwards and rest the handle on the floor.
•remove the suction hose sleeve (fig. E, ref. 4) from the squeegee;
•remove the squeegee (fig. E ref. 1) from its mount by completely unscrewing the two
knobs (fig. E ref. 2)
•remove the blade retainers and blades by unscrewing the knobs (fig. E, ref. 5);
•reuse the same blade by reversing the edge in contact with the floor until both edges
are worn out, or replace with a new blade, fitting it onto the screws on the body of the
squeegee;

ENGLISH
18
•replace the two blade retainers and the blades and screw up the knobs unscrewed
previously.
•Replace the squeegee in its support following the instructions in paragraph 6.2.
9.2.3 Fuses: replacement (battery models) (Fig. L)
The fuse protecting the electrical circuit is located on the battery bridge.
To replace it:
•make sure the dirty water tank is empty and empty if necessary;
•lift the dirty water tank to access the batteries;
•lift the fuse holder lid and remove the fuse;
•fit a new fuse and close the fuse holder cover.
•lower the dirty water tank.
Fuse table: for the complete fuse table, see the spare parts catalogue.
9.2.4 Fuses: replacement (cable models) (fig. M)
The fuses protecting the electrical components are on the electrical components box.
To replace:
•make sure the dirty water tank is empty and empty if necessary;
•lift the dirty water tank to access the electrical components compartment;
•open the cover of the fuse holder on the electrical components box and remove the
fuse;
