SQUEEGEE BLADE CHECK (AND
REPLACEMENT)
1.
Clean the squeegee (as described in the previous
paragraph).
2.
Check that the edges (5 and 12, Fig. D) of the front and
rear blades lay down on the same level, along all their
length; otherwise adjust their height as described below:
– disengage the retainer (6) and loosen the wing nuts
(7) to adjust the rear blade (4); then tighten the wing
nuts and engage the retainer;
– loosen the wing nuts (8) to adjust the front blade (3);
then tighten the nuts.
3.
Check that the front blade (3) and rear blade (4) are
integral and free from cuts and tears; otherwise replace
them as described below. Check that the front corner (9)
of the rear blade is not worn; otherwise, overturn the
blade to replace the worn corner with an integral one. If
the other corners are worn too, replace the blade as
described below:
– rear blade: disengage the retainer (6), unscrew the
wing nuts (7) and remove the retaining strip (10),
then replace (or overturn) the rear blade (4); install
the blade in the reverse order of removal;
– front blade: unscrew the wing nuts (8) and remove
the retaining strip (11), then replace the front blade
(3); install the blade in the reverse order of removal.
After the blade replacement (or overturning), adjust
the height as described at the previous step.
4.
Install the squeegee (16, Fig. C) and screw down the
handwheels (17).
5.
Connect the vacuum hose (24, Fig. C) to the squeegee
(16).
6.
If necessary, adjust the squeegee balance adjusting
handwheel (18, Fig. C).
BRUSH/CYLINDRICAL BRUSH CLEANING

the Use chapter.
2.
Clean and wash the brushes/cylindrical brushes with
water and solution.
3.
Check that the brush/cylindrical brush bristles are
integral and not excessively worn; otherwise replace the
brushes/cylindrical brushes.

On the cylindrical brush-holder deck, remove the debris
container (26, Fig. J) by pulling it on one side by means
of the handle (27).
Empty and wash the debris container (26), and then

TANK, VACUUM GRID WITH FLOAT AND
RECOVERY WATER RECIRCULATION FILTER
CLEANING (OPTIONAL)
1.
Bring the machine to the appointed disposal area.
2.
Check that the ignition key (10, Fig. B) is to "0" position.
3.
Lift the cover (1, Fig. G).
4.
Clean and wash with clean water the cover (1, Fig. G),
the tanks (4 and 5) and the vacuum grid (7).
Remove the plug (16, Fig. G) and clean the vacuum duct
with a bolt of water. Install the plug (16).
Drain the water from the tanks with the hoses (26 and
27, Fig. C).
5.
If necessary, release the retainers (13, Fig. G) and open
the vacuum grid (7); recover the float (14), clean all the
components and then reinstall them.
6.
Check the integrity of the gasket (2, Fig. G) on the tank
cover.
NOTE:
The gasket (2, Fig. G) creates vacuum in the
tank, which is necessary for vacuuming the
recovery water.
If necessary replace the gasket (2) after removing it
from its seat (10). When assembling the new gasket,
install its junction (11) in the central rear area as
shown in the figure.
7.
Check that the seating surface (12, Fig. G) of the gasket
(2) is integral and adequate for the gasket.
8.
Check that the compensation hole (3, Fig. G) is not
obstructed, otherwise clean it.
NOTE
The hole (3, Fig. G) allows compensating the
air in the cover and contributes to create
vacuum in the tank.
9.
If equipped, remove the recirculation system filter (8,
Fig. G) by turning it counter-clockwise. Clean and rinse
the filter with clean water, than reinstall it.
CAUTION!
When removing/installing the filter (8, Fig. G),
