BRUSHES ASSEMBLY
To assemble the brushes it is neces-
sary that the brushes base is in the
lifted position. If it is not lifted, proceed
as follows:
Without the operator seated, turning
the key switch clockwise, the display
comes on and after 3 seconds all
working groups come off automatically
and are lifted from the oor.
Switch off the machine turning the key
counterclockwise.
ATTENTION:
To carry out brushes assembly opera-
tions with the electric supply on, may
cause damages to hands.
With the brushes base group in lifted
position, insert the brushes into their
plate seat underneath the brushes
base turning them until the three metal
buttons are properly seated in their
slots; quickly rotate the brushes to
push the button towards the coupling
spring until they get blocked. The
gure shows the rotating direction for
brushes coupling.
For a longer life of the brushes we
suggest to invert daily their posi-
tion. Whenever brushes become
de¬formed we suggest to reassemble
them in the same position, in order
to avoid the different inclination of
the bristles to cause excessive motor
overload or troublesome vibrations.
ATTENTION:
Use only brushes supplied with the
machine or the ones indicated in
the paragraph “RECOMMENDED
BRUSHES”. The use of other brushes
can compromise the result.
FLOOR CLEANING
RECOVERY TANK
Check that the cover of the suction
lter (1) is correctly secured, after
rotating the levers (2) and that the
suction motor hose (3) is correctly
connected to it.
Verify also that the squeegee hose
couplings (4/5) are correctly inserted
into their seats and that the exhaust
hose plug (6) placed in the rear part of
the machine is well closed.
DETERGENT SOLUTION TANK
The capacity of the detergent solution
tank is indicated in the technical data.
Open the screw plug placed in the left
part of the machine and ll the deter-
gent solution tank with clean water
at a maximum temperature of 122°F
(50°C). Add the liquid detergent in the
percentage and conditions recom-
mended by the manufacturer. To avoid
excessive foam, which could cause
problems to the vacuum motor, use
the minimum percentage of detergent.
Screw down the plug to close the tank.
ATTENTION:
Always use low foam detergent. To
avoid foaming, before starting opera-
tions, introduce into the recovery tank
a minimum quantity of anti-foam prod-
uct. Never use pure acid.
3SD SYSTEM SOLUTION SAVING
SYSTEM DISPENSER (OPTIONAL)
The system permits the predetermined
dosing of the detergent percentage
which will be mixed with the water of
the solution tank. The detergent is
contained in a transparent tank with a
capacity of 8 liters, placed in the front
part of the machine.
With the brushes moving, pressing
the push button (A) on the instrument
board, on the display (1) the indication
shows the detergent percentage which
is being used.
