On consignment of the machine
When the machine is consigned to the customer, an immediate
check must be performed to ensure all the material mentioned in
the shipping documents has been received, and also to check the
machine has not suffered damage during transportation. If this is
the case, the carrier must ascertain the extent of the damage at
once, informing our customer service office. It is only by prompt
action of this type that the missing material can be obtained, and
compensation for damage successfully claimed.
Introductory comment
This is a floor scrubber-dryer which, via the mechanical action of
the rotating brush and the chemical action of a water/detergent
solution, can clean any type of flooring. As it advances, it also
collects the dirt removed and the detergent solution not absorbed
by the floor.
The machine must be used only for this purpose. Even the best
machines will only work well if used correctly and kept in good
working order. We therefore suggest you read this instruction
booklet carefully and re-read it whenever difficulties arise while
using the machine. If necessary, remember that our assistance
service (organised in collaboration with our dealers) is always
available for advice or direct intervention.

MACHINE PREPARATION
4. PUTTING THE BATTERIES IN THE MACHINE
The batteries must be housed in the battery compartment below the recovery tank. They
must be handled using special hoisting equipment with suitable grasping systems and
designed to support the weight of the batteries. The batteries must also conform to the
requirements given in CEI 21-5 standards.
WARNING! For the daily maintenance and recharging of the
batteries is necessary to follow strictly the guidelines supplied by
the manufacturer or its dealer. All installation and maintenance
must be performed by qualified personnel.
To insert the batteries is necessary:
-Make sure the recovery tank is completely empty
-Lift the recovery tank completely
-Slide the coupling of the prop on the outer hole (1) keeping the tank in an upright
position
-After inserting the battery hang up the shore to its original position
WARNING! To avoid irreparable damage to the solution tank and
/ or the recovery tank, keep recovery tank lifted when the prop is
released from its support.
5. CONNECTING THE BATTERY CONNECTOR
The battery connector (1) that is under the recovery tank, should be connected to the
machine connector (2).
6. CONNECTING THE BATTERY CHARGER
The battery charger connector is delivered inside the bag that contains this instruction
booklet. Il must be fitted lo the battery charger cables according to instructions.
WARNING! This operation must be performed by qualified
personnel. A wrong or imperfect cables connection to the
connector may cause serious harm to persons or property.

12
MACHINE PREPARATION
7. BATTERY RECHARGING
Batteries, to avoid permanent harm to them, should never be totally discharged. They
should be recharged within a few minutes after the battery discharged signal starts to flash.
Never leave the batteries completely discharged, not even if t he
machine is not being used. When recharging, first empty the
recovery tank and then remove it. Check the level of battery
electrolyte every 20 recharges. Top up with distilled water as
necessary.
WARNING! To recharge the batteries daily you must follow strictly
the guidelines supplied by the manufacturer or its dealer. All
installation and maintenance must be performed by qualified
personnel.
WARNING! Danger of emission of gas and leakage of corrosive
liquids
WARNING! Fire danger: Do not approach with open flames
8. BATTERY CHARGE LEVEL GAUGE
The battery charge level gauge is a digital unit with 4 fixed and one flashing position. The
numbers on the display give an approximate idea of the state of charge :
4= maximum charge, 3= 3/4 charge, 2= 2/4 charge '" 1= 1/4 charge, 0= no charge
(flashing).
IMPORTANT: the brush motor automatically turns off a few
seconds after the flashing "O" appears. The remaining charge can
be used to terminate drying operations before recharging.

13
MACHINE PREPARATION
9. ASSEMBLING THE SQUEEGEE
The squeegee is supplied separately, dismantled from the machine, far packing reasons. It
must be installed as illustrated, threading the retaining pin into the squeegee column. Put
the aspiration tube into its sleeve.
WARNING! Use gloves to avoid injury to the hands.
10. ADJUSTING THE SQUEEGEE
The rear rubber, during operation, must be slightly and uniformly bent back about 5 mm.
along its entire length. Il may be necessary, to increase curvature of the rubber in its
central section, to slope the squeegee body backwards. This is done by rotating
adjustment unit (2, fig. 3) counter-clockwise. To increase curvature on the outside
sections of the rubber just rotate adjustment unit (2, fig. 3) clockwise.
WARNING! Use gloves to avoid injury to the hands.
WARNING! Use gloves to protect themselves from contact with
dangerous solutions.
The squeegee should be adjusted in height depending on the wear of the tires. To do this,
turn the knob (2) clockwise (tighten) to raise the squeegee and counterclockwise
(unscrew) to decrease.
Note: The left and right wheels must be adjusted in the same way so that the squeegee
works parallel to the floor.

14
MACHINE PREPARATION
11. INSTALLING THE ROTATING BRUSHES
-Turn the ignition key to OFF and remove it from the panel
-Lift the base completely by lowering the control lever base
WARNING! Do the mounting of the brushes with the power on may
cause serious injury to hands.
WARNING! Use gloves to protect themselves from contact with
dangerous solutions.
-With the lifted basement, put the buttons on the nozzle plates in special niches of the
brush holder. Turn the left brush counterclockwise and the right brush clockwise until
you get the lock through the spring coupling applied to the brush holder
We recommend inverting right and left brushes every day and viceversa. If brushes are not
new and have distorted bristles then it is best to install them always in the same position
(the right brush on the right side and the left brush on the left side) lo prevent bristles with
a different slope from overloading the brush motor and causing excess vibrations.

15
MACHINE PREPARATION
12. RECOVERY TANK
-Open hood (1) and block it in its high position with support (2).
Check:
-that plug (5) is properly anchored
-that aspiration tube is inserted in its seat
WARNING! Always use low foam detergent. To avoid the
production of foam is recommended to introduce into the
recovery tank a small amount of foam agent before starting work.
13. SOLUTION TANK
Fill the solution tank with clean water at a temperature not in excess of 50·C. Add liquid
detergent in the amounts and using the procedures recommended by the detergent
manufacturer. Use only a minimal percentage of detergent to prevent formation of an
excess quantity of foam since too much foam may damage the aspiration motor.
WARNING! Always use low foam detergent. To avoid the
production of foam is recommended to introduce into the
recovery tank a small amount of foam agent before starting work.
WARNING! Never use pure acids.
WARNING! Use gloves to protect themselves from contact with
dangerous solutions.

during the first few meters of wash, that brush pressure is adequate (see "BRUSH
PRESSURE" below), that the amount of water is sufficient and that the squeegee dries
the floor perfectly. The machine will now start lo work at full efficiency until the
solution water is finished

17
WORK
WARNING! Immediately apply emergency brake (1) on the right
side of the machine whenever problems arise during operation.
This control stops forward movement by the machine. To start to
work again, after solving the problem, just raise lever (1) and
push deadman lever (2) forward.
OVERFLOW DEVICE
The machine has a float that trips whenever the recovery tank is full. This causes the
aspiration tube to close. In this case you should empty the recovery tank.
WARNING! Use gloves to avoid injury to the hands.
WARNING! Use gloves to protect themselves from contact with
dangerous solutions.
BRUSH PRESSURE
It is possible to adjust the brush pressure acting on the appropriate lever. There are three
different levels of brush pressure. The brush pressure is higher when the lever is fully lifted.
Pressure should be selected depending on the type of floor and the amount of dirt. Too
much pressure causes increased brush wear and greater energy consumption.
TRACTION
These machines are equipped with electronically-controlled traction with continuous speed
variation. Maximum speed can be selected according lo three levels.
- for very dirty floors, where it is necessary to proceed slowly, or for paths with lots of
obstacles where great steering precision is required
- for loose or uneven floors where a high speed could cause drying problems
- for normaI floor maintenance cleaning

18
WORK
TRACTION
The operator selects the optimum speed based on what happens while he works and on
his own experience. To move the machine turn key (1), check the speed that is engaged
(2) and then turn the deadman lever (3) on the handlebar forward (forward movement) or
backward (reverse movement).
