BRUSHES ASSEMBLY
To assemble the brushes it is necessary 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 floor.
Switch off the machine turning the key counterclockwise.
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; rotate
energically the brushes to push the button towards the coupling
spring until they get blocked.
The figure shows the rotating sense for brushes coupling.
For a longer life of the brushes we suggest to invert daily their
position. Whenever brushes result to be deformed we suggest to
reassemble them in the same position, in order to avoid that the
different inclination of the bristles causes excessive motor overload
or troublesome vibrations.
Use only brushes supplied with the machine or the ones indicated in
the manual “RECOMMENDED BRUSHES”. The use of other brushes can
compromise the good washing result.
FLOOR CLEANING
RECOVERY TANK
Check that the cover of the suction filter (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 fill
the detergent solution tank with clean water at a maximum
temperature of 50°C. Add the liquid detergent in the percentage and
conditions foreseen by the manufacturer. To avoid excessive foam
presence, which could cause problems to the suction motor, use the
minimum percentage of detergent. Screw down the plug to close the
tank.
Use always low foam detergent. To avoid foam presence, before
starting working operation, introduce into the recovery tank a
minimum quantity of anti-foam product.
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
litres, placed in the front part of the machine.
