TANK AND VACUUM GRID CLEANING

1. Drive the machine to the appointed disposal area.
2. Make sure that the power supply cable (21) is disconnected from the electrical mains.
3. Open the cover (6), then clean and wash the cover, the tanks (26 and 27) and the vacuum grid (36) with clean water.
Drain the water from the tanks with the drain hose (16) and the valve (18).
4. If necessary, release the fasteners (B, Fig. 5) and open the grid (A); recover the fl oat (C), clean all the components and then
reinstall them.
5. Check the recovery tank cover gasket (D) for integrity.
NOTE
The gasket (D) creates vacuum in the tank that is necessary for vacuuming the recovery water.
If necessary replace the gasket (D) by removing it from its housing (E).
When assembling the new gasket, install the joint (F) in the rear central area, as shown in the fi gure.
6. Check the seating surface (D) of the gasket (G) for integrity and sealing capabilities.

NOTE
The hole (28), allowing to compensate the air in the cover air gap, contributes to create vacuum in the tank.
