On consignment of the machine
When the machine is delivered 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 been
damaged 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 abrasive
mechanical action of the two rotating brushes 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 read it again 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
RECHARGING THE BATTERIES
Check the battery charger is suitable for the batteries installed, in terms of both
capacity and type (lead/acid or GEL and equivalents).
WARNING: never charge a GEL battery with an unsuitable battery
charger. Follow the instructions given by the battery/battery charger
manufacturer with the utmost attention.
In order not to cause permanent damage to the batteries it is essential to
avoid their complete discharge: arrange the recharge within a few
minutes of the switching on of the flashing "discharged batteries" signal.
NOTES: never leave the batteries completely discharged, even if the
machine is not being used.
WARNING! For the daily recharging of the batteries, you must fully
respect the indications provided by the manufacturer or retailer. All
installation and maintenance operations must be carried out by
specialised personnel. Danger of exhalation of gas and leakage of
corrosive liquids. Danger of fire: do not go near with naked flames
BATTERY INDICATOR
The battery indicator is digital, with 4 fixed positions and a flashing one. The numbers
which appear on the display show the approximate charge level.
4= maximum charge, 3= 3/4 charge, 2= 2/4 charge, 1= 1/4 charge,
0= discharged batteries (flashing)
WARNING! A few seconds after the appearance of the flashing “0”, the
brush motor switches off automatically. With the remaining charge it is
possible to complete the drying process before starting the recharge.
ASSEMBLING THE SQUEEGEE
For packaging reasons, the squeegee is supplied disassembled from the machine, and
must be assembled as shown in the figure, inserting the clip into the small column of
the squeegee.
Insert the squeegee tube in the special sleeve.

1111
MACHINE PREPARATION
ADJUSTING THE SQUEEGEE HEIGHT
The height of the squeegee must be adjusted on the basis of the state of wear and tear
of the rubber. To do this, turn the wing nuts (1) anticlockwise to raise the squeegee,
and clockwise to lower it.
Remarks: the right and left wheels must be adjusted to the same level, so the
squeegee can work parallel to the floor.
1
ADJUSTING THE SQUEEGEE INCLINATION
During working operation, the rear rubber is tilted slightly backwards (by about 5mm) in
a uniform way for its whole length. If it is necessary to increase the bend of the rubber
in the central part, you must tilt the squeegee backwards, rotating the adjuster (1)
anticlockwise. To increase the bend of the rubber at the sides of the squeegee, rotate
the adjuster clockwise. When fully adjusted, fix the lock nut.
5mm
RECOVERY TANK
Open the cover and check the suction cap (2) is correctly blocked (insert the notches in
their housings, rotating the cap clockwise) and correctly connected to the tube leading
to the suction motor.
In addition, check the squeegee tube (1) is correctly inserted in its housing, and that
the drainage tube cap (in the rear part of the machine) is closed.

2
DETERGENT SOLUTION
Fill the solution tank with clean water at a temperature no greater than 50°C and add
liquid detergent in the proper concentration, following the instructions of the
manufacturer. The formation of excess foam could damage the suction motor, so use
only the minimum amount of detergent necessary. Reassemble the cap.
WARNING! always use low foam detergent. To avoid the production of
foam, before starting to clean, put a minimum quantity of antifoam
liquid into the recovery tank. Never use pure acid.

TROUBLESHOOTING GUIDE
INSUFFICIENT WATER ON THE BRUSHES
Check that the tap (1) is turned on.
Check there is water in the solution tank
1
THE MACHINE DOES NOT CLEAN WELL
Check the state of wear and tear of the brushes and, if necessary, replace them (the
brushes must be replaced when the bristles are about 15mm long).
To replace the brushes, see “DISASSEMBLING THE BRUSHES” and “ASSEMBLING
THE BRUSHES”.
Use a different kind of brush to the one fitted as standard. For cleaning floors where
the dirt is particularly resistant, we recommend the use of special brushes supplied
upon request and according to needs (see “CHOOSING AND USING THE
BRUSHES”).
THE SQUEEGEE DOES NOT DRY PERFECTLY
1. Check the squeegee rubbers are clean
2. Adjust the inclination of the squeegee (see "SQUEEGEE" under “MACHINE
PREPARATION”)
3. Check the suction tube is correctly inserted in its housing on the recovery tank
4. Disassemble the entire suction unit and clean it
5. Replace the rubbers, if worn
6. Check the suction motor switch is turned on
7. Check wheel adjustment
EXCESSIVE FOAM PRODUCTION
Check that a low foam detergent has been used. If necessary, add a small quantity of
antifoam liquid to the recovery tank.
Remember that, when the floor is not very dirty, more foam is generated. In this case
the detergent solution should be more diluted.

20 2120 21
CHOOSING AND USING THE BRUSHES
POLYPROPYLENE BRUSH (PPL)
Used on all types of floors. Good resistance to wear and tear, and hot water (no greater than 60°C). The Polypropylene brush is
non-hygroscopic and therefore retains its characteristics even when working in wet conditions.
NYLON BRUSH
Used on all types of floors. Excellent resistance to wear and tear, and hot water (even over 60°C). The nylon is hygroscopic and
so tends to lose its characteristics over time when working in wet conditions.
ABRASIVE BRUSH
The bristles of this type of brush are charged with highly aggressive abrasives. It is used to clean very dirty floors. To avoid floor
damage, work only with the pressure strictly necessary.
THICKNESS OF THE BRISTLES
Thicker bristles are more rigid and are therefore used on smooth floors or floors with small joints.
On uneven floors or those with deep joints, it is advisable to use softer bristles which can enter the gaps more easily.
Remember that when the bristles are worn and therefore too short, they will become rigid and are no longer able to penetrate
and clean deep down. In this case, like with over-large bristles, the brush tends to jump.
PAD HOLDER
The pad holder is recommended for cleaning shiny surfaces.
There are two types of pad holder:
1. the traditional pad holder is fitted with a series of anchor points that allow the abrasive floor pad to be held and dragged
while working
2. the CENTER LOCK type pad holder not only has anchor points, but also a snap-type central locking system in plastic that
allows the abrasive floor pad to be perfectly centred and held without any risk of it becoming detached. This type of
dragging device is recommended above all for machines with more than one brush, where the centring of the abrasive
discs is difficult.
