TANK AND VACUUM GRID WITH FLOAT
CLEANING, AND COVER GASKET CHECK
1. Drive the machine to the appointed disposal area.
2. Turn the ignition key (A, Fig. 32) to "0".
3. Open the tank cover (A, Fig. 33) to position (L).
4. Wash with clean water the cover (A), the tanks (B and C) and
the vacuum grid with automatic shut-off float (D).
5. Drain the water from the tanks with the hoses (B and C, Fig.
32).
If necessary, disengage the fasteners (E, Fig. 33) and open
the grid (D); recover the float (F), clean all the components
and then reinstall them.
6. Check the tank cover gasket (G) for wear.
NOTE
The gasket (G) creates vacuum in the tank that is
necessary for vacuuming the recovery water.
If necessary replace the gasket (G) by removing it from its
housing (H). When assembling the new gasket, install the
joint (I) in the rear central area, as shown in the figure.
7. Check that the seating surface (J) of the gasket (G) is
integral and adequate for the gasket itself.
NOTE
The hole (K), allowing to compensate the air in the cover
air gap, contributes to create vacuum in the tank.
8. Close the cover (A).
