2. Clean and wash the brushes/pads with water and detergent.
3. Check that the brush/pads are integral and not excessively worn; otherwise replace them.
4. On the machines equipped with the cylindrical brush deck, remove the debris container (D, Fig. 3) by pulling it on one side
with the handle (E).
Empty and wash the debris container (D), and then install it by engaging it on the retainers.

TANK AND VACUUM GRID WITH FLOAT CLEANING, AND COVER GASKET CHECK

1. Drive the machine to the appointed disposal area.

5. If necessary, release the retainers (E) 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 integrity.
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 bearing 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 interspaces, contributes to create vacuum in the
tank.
