RECEIVING THE MACHINE
Immediately check, when receiving the machine, that all the
materials indicated on delivery documents have been
received and also that the machine has not been damaged
in transit. If it has been damaged, this damage must be
immediately reported to the shipper and also to our
customer’s service department. Only acting promptly in this
manner will make it possible to receive missing material and
to be compensated for damage.
SERIAL # PLATE
INTRODUCTION
This is an automatic scrubber 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 and customer service
(organized in collaboration with our dealers) is always
available for advice or direct intervention.

even if the machine is not being used. This can cause permanent
damage to them. While recharging, keep the recovery tank raised,
supporting it with the prop as shown in the figure. Ensure the
battery charger is suitable for the batteries installed, in terms of
capacity and type.
Danger of exhalation of gas and leakage of corrosive liquids.
Danger of fire: do not go near with open flames.

MACHINE PREPARATION
15. ADJUSTING THE SQUEEGEE HEIGHT
The height of the squeegee must be adjusted based on wear and tear of the
squeegee. To do this, turn the knob (2) counter clockwise to raise the squeegee,
and clockwise to lower it.
Note: the right and left wheels must be adjusted to the same level, so the
squeegee can work parallel to the floor.

16. ADJUSTING THE SQUEEGEE INCLINATION
During working operation, the rear squeegee is slightly tilted backwards (by about
0.2 in (5mm)) uniformly over its whole length. If it’s necessary to increase the bend
of the squeegee in the center, you must tilt the squeegee backwards, rotating the
adjuster (1) counter clockwise. To increase the bend of the squeegee at the sides
of the squeegee, rotate the adjuster clockwise. When fully adjusted, tighten the
j
am nut.
17. RECOVERY TANK
Check the drain hose cap (on the rear of the machine) to ensure it’s closed.

MACHINE PREPARATION
18. SOLUTION TANK
Remove the front inlet cap and check the solution filter is correctly fitted.
Check the filter cover (beneath the tank) is correctly closed.
19. SOLUTION TANK
Fill the tank with clean water in the front fill location (1) or at the rear fill location (2)
at a temperature not exceeding 120°F (50°C).
Y
ou can check the level of solution in the tank by means of the rear hose (3).
A
dd the liquid detergent into the tank, in the concentration and manner specified
by the manufacturer. The formation of excess foam could damage the vacuum
motor, so be sure to use only the correct amount of detergent.
WARNING: Always use low-foam detergent. Introduce a small
amount of anti-foam detergent in the recovery tank before
starting to work to prevent foam from being generated.
WARNING: Never use pure acids.

20. ASSEMBLING THE BRUSH (BASE WITH DOUBLE BRUSH)
1
.
With the brush deck up, insert the brushes in the brush housing beneath the
deck base, turning them until the three pins enter the notches in the plate
itself; turn the brush until the pin is pushed towards the coupling spring and is
locked into place. The figure shows the brush rotation direction for the right-
hand brush; the left-hand brush rotates in the opposite direction.
WARNING: Make sure there are no objects or people in the
vicinity of the brush when doing this operation
2
.
Swap the right and left-hand brushes every day. If the brushes are used and
have deformed bristles, it is better to reassemble them in the same position
(the right-hand one on the right, and the left-hand one on the left), to prevent
the deformed bristles overloading the brush motor as well as excessive
vibration.
21. REGULATING THE SOLUTION
Regulate the quantity of water by means of the side valve (1).

2. Turn the key (1) of the main switch to the "ON" position (clockwise). The battery
charge level indicator lights will immediately come on.
3. Turn on the water valve (2) (the water falls automatically while the brushes are turning).
4. Release the lever (3) and lower the scrubbing head. If the floor is particularly dirty, you
can apply an overpressure to the scrubbing head by raising the pedal (3) until the lock
down is triggered.
5. Lower the squeegee, turning the lever (4) counter clockwise. The vacuum motor will
switch on.
6. Check that the brake (5) is off.
7. Pressing the paddles (1), activates the brushes and the machine begins to move
(model with traction). During the first feet, check the amount of solution is correct,
and that the squeegee dries the floor perfectly.
8. The machine will now start to scrub and dry until the solution tank is empty or
recovery tank is full.

hose for obstructions. To clean it, proceed as follows:
1. Remove the hose from the sleeve on the squeegee
2. Remove the other end from the recovery tank
3. Wash the inside of the hose with water introduced from the side where it is
connected to the tank
4. Reassemble the hose
WARNING: Always wear gloves when doing this operation to
protect yourself from contact with hazardous chemicals
2. CHECKING THE BRAKE
Every week, check the distance between the work brake pads and the wheels. If

TROUBLESHOOTING
INSUFFICIENT WATER ON THE BRUSH
1. Check the valve – located beneath the symbol – (1) is turned on.
2. Check there is water in the solution tank.
THE MACHINE DOES NOT CLEAN WELL
1. Check the state of wear and tear of the pad and, if necessary, replace it.
2. Use a different kind of pad 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 blades are clean.
2. Adjust the inclination of the squeegee (see "SQUEEGEE" under “MACHINE
PREPARATION”)
3. Ensure the vacuum hose is correctly inserted in its housing on the recovery tank.
4. Check the inner filter of the recovery tank to ensure it is not dirty and, if necessary,
clean it thoroughly.
5. Disassemble the entire vacuum unit and clean it.
6. Replace the squeegee blades, if worn.
7. Ensure the vacuum motor switch is turned on.
8. Check wheel adjustment.
TOO MUCH FOAM IS GENERATED
Check that low-foam detergent is being used. If necessary add a small amount of anti-
foam liquid to the recovery tank.
Remember that more foam is generated when the floors are not very dirty. Dilute the
detergent more when cleaning floors that are not very dirty.
