BRUSH/PAD CLEANING
CAUTION!
It is advisable to wear protective gloves when cleaning the brush/pad because there may be sharp debris.
Remove the brushes/pads from the machine, as shown in Use chapter.
Clean and wash the brushes/pads with water and detergent.
Check the brushes/pads for integrity and wear; if necessary replace them.
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 fasteners.
TANK AND VACUUM GRID WITH FLOAT CLEANING, AND COVER GASKET CHECK
Drive the machine to the appointed disposal area.
Turn the ignition key (80) to “0”.
Open the cover (A, Fig. 6).
Drain the water from the tanks with the hoses (16 and 17).
Wash with clean water the cover (A), the tanks (B and C) and the vacuum grid with automatic shut-off float (D).
If necessary, release the fasteners (E) and open the grid (D), recover the float (F), clean all the components and then reinstall
them.
Remove and clean the debris tray (M).
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.
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.
