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

order of removal.
After the blade replacement (or overturning), adjust
their height as described in the previous step.

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

is not fitted on the machine, it is necessary to empty
the tank (5, Fig. G) as described in the specific
