SQUEEGEE BLADE
CHECK/REPLACEMENT
1. Clean the squeegee as described in the previous
paragraph.
2. Check that the edges (5, Fig. D) of the front and rear
blades (12) 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 nuts (8) to adjust the front blade (3); then
tighten the nuts.
3. Check that the front and rear blades (3 and 4) are
integral and free from cuts and lacerations; 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:
– To replace (or overturn) the rear blade (4) disengage
the retainer (6), unscrew the wing nuts (7) and the
retaining strip (10). Install in the reverse order of
removal.
– To replace the front blade (3) remove the nuts (8)
and the retaining strip (11). Install in the reverse
order of removal.
After the blade replacement (or overturning), adjust
their height as described in the previous step.
4. Reinstall the squeegee assembly (10, Fig. C) in the
correct position and screw down the knobs (11).
5. Connect the suction hose (26, Fig. C) to the squeegee
(10).
6. If necessary, adjust the balancing knob (12, Fig. C) of the
squeegee.

INSTRUCTIONS FOR USE
TANK AND SUCTION CAGE WITH FLOAT
CLEANING
1. Bring the machine to the appointed disposal area.
2. Check that the switches (5 and 6, Fig. B) are in "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 screen (7) of the suction
automatic cut-off.
Drain the water from the tanks with the hoses (17 and
18, Fig. C).
5. If necessary, release the retainers (10, Fig. G) and open
the screen (7); recover the float (11), clean all the
components and then reinstall them.
6. Check that the tank cover gasket (2, Fig. G) is integral.
NOTE
The gasket (2) creates suction in the tank for
recovery water vacuuming.
If necessary replace the gasket (2, Fig. G) after removing it
from its housing (9). When assembling the new gasket, install
its joint (12) in the (central rear) area as shown in the figure.
7. Check that the gasket (2, Fig. G) seating surface (13) is
integral and adequate for the gasket.
8. Check that the compensation hole (3, Fig. G) is not
clogged, otherwise clean it.
NOTE
The hole (3, Fig. G), allowing to compensate
the air in the cover interspaces, also creates
vacuum in the tank.
9. Close the cover (1, Fig. G).

SOLUTION FILTER CLEANING

1. Rotate and close the solution tap (5, Fig. F). If the tap
is not fitted on the machine, it is necessary to empty
the tank (5, Fig. G) as described in the specific
paragraph.
2. Drive the machine on a level ground.
3. Check that the switches (5 and 6, Fig. B) are in "0"
position.
4. Operating under the right lower side of the machine,
remove the transparent cover (1, Fig. F) and the wire
gauze (2); then clean and reinstall them on the support
(3).
NOTE
The wire gauze (2) must be correctly
positioned on the support (3) housing (4).
