Amperometric to the positive cable of the
batteries and check if the current consumption is less than normal function
(without ECO mode). ATTENTION. We
don’t give the amperometric values because it can change depending of the
working conditions.

Mechanical Rubbing System
6.1 Structure
1. Motor
2. Bumping Wheel
3. Brush Base
4. Brush bushings
5. Adjustment system
6.2 Description
The washing function of the machine
is obtained by the interaction of the
cleaning solution with the dirt present
on the floor. To facilitate and enhance
this interaction, is used a system of
mechanical rubbing which consists in
a device which rubs on the floor. This
device can be of various nature (pad
or brush), in each case, its function is
to mechanically remove the dirt from
the ground and facilitate the reaction
between the dirt and cleaning solution. A direct current electric motor
connected to a case of gear reduction
provides the rotational movement of the
brush coupling flange. To the flange is
coupled the brush (or the pad holder
provided with pad) that rotates together
with the flange. After lowering the base
to the ground, the brush touches and
rubs on the floor providing the desired
mechanical rubbing.
67
Page 68
6-68
6.3 Adjustments
6.3.1 Adjustment system
The base must be free to move pivoted to
its support so that the brush acts parallel to the floor.
This allows the brush to evenly lean
to the ground and perform its function
properly.
Requirements: mounted brush, switched
off machine.
Procedure:
• Hook the brush to the base.
• Adjust the knob for the direction ad-
justment (see fig. 6.3.1-5) and the tilt adjusting screw (see fig. 6.3.1-6) so that the
brush lies uniformly and parallel to
the floor.
6.3.1-5 Directionality 6.3.1-6 Tilt
6.4 Maintenance and
checks
6.4.1 Motor
Checks:
The motor should rotate evenly and
smoothly. It’s important that the reduction case is not noisy and that the motor
current consumption is not higher than
the declared on the plate, regardless of
the load which it is subjected. It is necessary that the motor carbon brushes
are always in good condition and show
no signs of abnormal wear.
Maintenance:
Motor carbon brushes replacement:
Procedure:
• Secure the machine.
• Remove the base from the machine.
• Loosen the screws that secure the
collar brush guard. (see fig. ??)
• Unscrew the Carbon brushes connector from the input power line to
the motor. (see fig. ??)
Page 69
6-69
• Replace the carbon brushes being
careful not to ruin them during assembly. (see fig. ??)
• Proceed to the reverse operations to
reassemble it all.
6.4.2 Brass bushings
Checks:
The brass bushings allow a fluid and
little tiring rotational movement of the
base. To prevent the base is locked in a
position without the possibility of movement, is important that the brass bushings are in good condition and clean. In
case of excessive wear it is necessary to
proceed with the replacement.
Maintenance:
Brass bushings replacement:
Procedure:
• Secure the machine.
• Remove the screws that secure the
base to the machine body.
• Remove the base from the machine.
6.4.2-7 Base fixing screws 6.4.2-8 Base fixing screws
• Remove the bushings and replace
them with new bushings.
• Proceed to the reverse operations to
reassemble it all, sprinkle the new
bushings with lubricating grease before mounting.
• Adjust to the base once finished.
Page 70
6-70
6.4.3 Bumping Wheel
Checks:
The bumping wheel (see fig. ??) must be free
to rotate and its diameter must not be
too small due to wear. A bumping wheel
in poor condition can lead to cracking of
the brush base when working skimming
some obstacles (walls, shelving, etc).
If necessary, replace it (see section 4.2.6 at page
25).
6.4.4 Brushes Base
Checks:
The basement must be kept clean and
intact. A ruined basement may be dangerous to the machine and the operator
that uses it.
If necessary, replace it (see section 4.2.6 at page
25).
6.4.5 Brush coupling flange
Checks:
The brush coupling flange is of plastic material and is not subject to particular wear. Like the other components its cleanliness is essential to allow the brush to engage and disengage
smoothly. ’It is also essential that the
brush locking spring has full functionality in order to keep the brush in the
correct position. If necessary, replace it
(see section 4.2.6 at page 25).
6.4.6 Fixing and adjustment
plate
Checks:
The fixing plate (see fig. ??) must be in
good condition, must not show signs of
corrosion or deformation. An incorrect
fixing and adjustment plate does not
allow the entire Mechanical Rubbing
group to work properly.

2. Squeegee adjustment
3. Vacuum Hose
4. Recovery Tank
5. Filter and Floating
6. Vacuum Manifold
7. Vacuum Motor
7.2 Description
The machine dries the floor using an integrated Drying System. After the washing, the solution used with the mechanical action of the brush to remove the
dirt, is collected by a system which vacuum it out from the floor. The system
is basically made by a vacuum motor
which produces an underpressure in the
system. This underpressure causes an
air flow which flows in the whole vacuum circuit. The air that flows in the
squeegee (when it is lowered on the floor)
allows it to collect the water on the floor
mixing it with the water and, via the vacuum system, is brought to the recovery tank. In the recovery tank the water mixed with the dirt stops and the
air keep flowing throughout the circuit
reaching the vacuum motor and being
discharged in the environment via the
exhaust manifold.
72
Page 73
7-73
7.3 Adjustments
7.3.1 Squeegee Support
The Squeegee Support has to be adjusted with the Squeegee fitted on, lowered on the floor and vacuum system on.
The goal of the adjustment is to let the
squeegee blade be angled 45 degrees to
the floor for its whole length.
To obtain the proper squeegee adjustment act on the wing nuts to adjust the
wheels of the squeegee support to obtain
the proper height of the squeegee from
the floor (see fig. 7.3.1-9) and the inclination
screw to let the blade be bended equally
for its whole length (see fig. 7.3.1-10).
7.3.1-9 Height/Pressure 7.3.1-10 Inclination
Procedure
• Put the machine in safe conditions.
• Lower the squeegee on the floor.
• Act on the wheel nuts (see fig. 7.3.1-9)
until the wheels are lifted 1,5 mm
(±0,1mm eventually help the adjustment with a spacer of that thickness).
• Act on the inclination screw (see fig.
7.3.1-10) in order to let the blade be
equally angled for its whole length.
• Check the obtained adjustment with
a functional test.
Page 74
7-74
7.4 Maintenance and
Checks
7.4.1 Squeegee
Checks
To have a good performance of the
squeegee the blades have to be in a good
conditions. The squeegee chamber and
the squeegee adapter have to be clean

mandatory that the hose has no crack to
not decrease the underpressure. To verify the vacuum hose goodness turn on
the vacuum motor and block the lower
part of the hose with the hand, in this
way there must be no air passage.
7.4.3-20 Vacuum Hose 7.4.3-21 Vacuum Hose
7.4.4 Filter and Floater
Checks
The filter has to be clean and it is important that nothing blocks or reduces the
floater mobility. The filter has to be clean
to avoid that water or dirt goes inside the
vacuum motor, the floater has to be free
to move and has to block completely the
air flow when it is in blocking position
(UP).
Maintenance
• Put the machine in safe conditions.
• Check that the recovery tank is com-
pletely empty.

Machine Frame and Traction System
8.1 Structure
1. Frame
2. Front Wheels
3. Parking Brake Lever (IMx BT only)
4. Traction Motor (IMx BT only)
8.2 Description
The frame is a single structure on which
are coupled the traction system (only
IMx BT) and the tanks group. In the IMx
B and BB models the machine traction is
ensured by the mechanical friction system; in the IMx BT version the machine
traction is given by the electric motor installed in conjunction with a reduction
gear, whose output shafts act directly on
the machine front wheels, ensuring traction. All models are fitted with mixed antiskid / non-marking wheels. The IMx
BT model has a parking brake that acts
on the traction wheels through a control
lever (see fig. 8.3.1-33) situated in proximity of
the right front wheel.

Lever
Procedure
• Secure the machine.
• Unscrew the adjusting nut, so as
to appropriately increase or decrease
the run of the buffer.
• Check the correct operation of the
parking brake.
• Lock the adjusting nut.
8.4 Maintenance and
Checks
8.4.1 Wheels
Checks
The wheel must be free to rotate
smoothly without friction. The wheel
surface, must always be in good condition.
Maintenance
Periodically check the condition of the
bearings and bushings of the wheels. If
necessary, replace the part (see section 4.4.1
at page 32).
8.4.2 Traction Motor (Only IMx
BT model)
Checks
During normal driving, the power consumption must be between 3 and 5
Amps.
ATTENTION: At the start, the power
consumption of the motor is much
higher.
The carbon brushes of the traction motor must be at least 6-8 mm long. The
insulation of the motor supply cables
should be complete in every part and
show no signs of cracks. The cables
must be flexible. When lifting the machine to put the front wheels in neutral
by spinning a wheel (in any sense) the
other must turn in the opposite direction.

Cleaning Solution Supply System
9.1 Structure
1. Solution Tank
2. Hoses
3. Water Valve
4. Solution Filter
5. Solenoid Valve
6. Distributor
9.2 Description
The Cleaning Solution Supply System is
made by a tank commonly called solution tank or clean water tank. In this
tank the clean water is mixed with the
detergent to create the cleaning solution
that the machine will use to clean. The
solution is then canalized to the filter
and the water valve. The filter is used
to stop debris that could stuck the hose
system, the water valve is used to adjust
the solution that will fall on the floor (BB
Version) or to allow or stop the liquid delivery (B and BT Version).
Once passed through the water valve
the solution arrive to the solenoid valve
that blocks the delivery when the brush
is not working and allow the flow while
brush works. In the B and BT versions the solenoid valve is electrically
controlled to adjust the solution flow
rate. The end of the solution path is the
distributor that canalizes the flow in the
middle of the brush.

9.3 Maintenance and
Checks
9.3.1 Solution Tank
Controls:
The solution tank has to be clean and
intact. It has not to have cracks or any
other kind of damage. Verify, when the
tank is completely filled up, that there
are not leakage. If necessary replace the
Solution Tank. (see section 4.5.1 at page 35).
Figure 9.1: Solution Tank
9.3.2 Hoses
Checks:
Every single hose has to be intact and
has not to be worn out. It is extremely
important that the hoses kept the original flexibility and they haven’t suffered
any chemical reaction with the detergent
used with the machine. If necessary proceed with the replacement of the damaged hoses (see section 4.5.2 at page 36).
9.3.3 Water Valve
Checks:
It is extremely important that when adjusted at minimum the valve blocks
completely the water flow and it is mechanically free to move for its while
stroke.
Figure 9.2: Water Valve
9.3.4 Clean Water Filter
Checks:
The filter has to be periodically cleaned.
When it is fitted on the machine no leakage has to be present. The filter cartridge
has to be intact and has not to present
any anomaly.
Figure 9.3: Clean Water Filter
Page 85
9-85
9.3.5 Solenoid Valve
Checks:
The solenoid valve has to block completely the solution flow when the brush
deck is not working. Viceversa it has to
grant the full flow rate when the brush
deck is working.
Figure 9.4: Solenoid Valve
9.3.6 Distributor
Controls:
The distributor has to be intact and has
to grant the proper solution flow without
any leakage in the gearbox.
