6.10. Draining the clean water

Use suitable personal protection devices.
To empty the tank:
• move the machine near a drain;
• remove the cap (fig. 8, ref. 1);
• when the detergent tank is completely empty, replace the cap (fig. 8, ref. 1).
The water and detergent solution can also be used to wash the dirty water tank.
If the machine is not used for some time, remove the squeegee and brushes (or drive
disks), wash them and put them away in a dry place (preferably in a bag or wrapped in
plastic film) away from dust. Park the machine with the head lowered.
Make sure the tanks are completely empty and perfectly clean.
Disconnect the machine from the power supply.
Completely recharge the batteries and deposit them in the battery store. During long
periods of inactivity, you should charge the batteries regularly (at least once every two
months) to keep them constantly at maximum charge.
If you do not charge the batteries regularly, they may be irreparably damaged.
