ATTENTION:
Use only brushes supplied with the machine or the
ones indicated in the paragraph "RECOMMENDED
BRUSHES". The use of other brushes can compromise
security.
RECOVERY TANK
Check that the cover of the suction filter (1) is cor-
rectly secured, after rotating the levers and that the
suction motor hose (2) is correctly connected.
Verify also that the squeegee hose is correctly in-
serted into the seats (3 and 4) and that the exhaust
hose plug (5) placed in the front part of the machine,
is closed.
DETERGENT SOLUTION TANK
The capacity of the detergent solution tank is indi-
cated in the technical data.
Open the screw plug (1) placed in the rear left part
of the machine and fill the detergent solution tank
with clean water at a maximum temperature of 50°C.
Add the liquid detergent in the percentage and con-
ditions foreseen by the manufacturer. To avoid ex-
cessive foam presence, which could cause problems
to the suction motor, use the minimum percentage
of detergent. Screw down the plug to close the tank.
ATTENTION:
Use always low foam detergent. To avoid foam pres-
ence, before starting working operation, introduce
into the recovery tank a minimum quantity of anti-
foam product.
Never use pure acid.
FLOOR CLEANING
STARTING OF THE MACHINE
The machine is equipped with a mains cable com-
plete with a plug for the connection to the mains
system and with a socket connector to insert inside
the plug (16) situated underneath the instrument
board.
1. Insert the socket inside the machine plug (16).
2. Hook the cable onto the support (17) to avoid
that probable tears can damage the socket.
3. Insert the plug into the appropriate mains socket
and check that on the instrument board the signal
lamp for tension presence comes on (5).
4. For machines equipped with key switch (see un-
der "OPTIONAL ACCESSORIES"), turn the key (8)
clockwise to switch on the machine, counterclock-
wise to switch it off.
5. Press the brushes motor switch (1).
6. Press the switch of the suction motor (2) and this
will start to function.
7. Acting upon the solution valve lever (10) adjust
the solution detergent quantity bringing the floor
uniformly wet, avoiding the leakage of detergent
from the splash guards. Always consider that the
correct quantity of solution detergent depends on
type of floor, dirtiness and machine speed.
8. For machines optionally equipped with solenoid
valve (see under "OPTIONAL ACCESSORIES") the flow
of detergent solution will be activated automatically,
once the solution valve has been opened through
the lever (10), acting upon the levers presence (9).
On the instrument board the signal lamp of the open
solution valve will come on (6). Releasing these lev-
ers, flow will stop automatically.
9. Acting upon the brushes base lifting pedal (12)
lower the brushes base.
10. Acting upon the squeegee lifting lever (11) lower
the squeegee.
11. Activating the levers (9), the brushes will start
rotating transferring to the machine a forward
movement. The squeegee will start drying the floor.
12. During the first meters check that the detergent
solution flow is appropriate and that the squeegee
adjustment guarantees a perfect drying action.
ADJUSTMENT OF THE BRUSHES PRESSURE (OP-
TIONAL)
Through the register (1) placed in the inner part near
the front right wheel, it is possible to adjust the
brushes pressure on the cleaned surface.
By turning the wing nut clockwise the pressure in-
creases, rotating the wing nut counterclockwise, the
pressure decreases.

This device allows a more efficient cleaning action
also on very difficult and dirty surfaces.
BRUSHES MOTOR OVERLOAD PROTECTION DE-
VICE
The machine is equipped with a protection device (7)
that intervenes in case of an overload of the brushes
motor disconnecting the motor. If the protection de-
vice intervenes again and often, contact the author-
ized technical assistance.
ATTENTION:
To reset the brushes motor, turn off the brushes
motor switch (1) for a few seconds and turn it on
again, rearm the push button of the protection
device (7).
OVERFLOW DEVICE
In order to avoid serious damages to the suction mo-
tor, the machine is equipped with a float that inter-
venes when the recovery tank is full, closing the suc-
tion hose and stopping the suction.
When this happens, it is necessary to take off the
plug from the mains socket and to empty the recov-
ery tank.
1. Hold the exhaust hose placed in the front part of
the machine.
2. Take off the exhaust plug acting upon its lever
and empty the recovery tank into appropriate con-
tainers, according to the standard norms.
ATTENTION:
This operation must be carried out using gloves to
protect from contact with dangerous solutions.
