• detach the drain hose (fig. 16, ref. 1) from its seat, holding it in correspondence with
the fixing spring (fig. 16, ref. 2) and pull it horizontally;
• keeping the hose end as much high as possible, take off the drain cock (fig. 16, ref. 3)
from the hose by unscrewing it;
• lower the hose end gradually, checking the intensity of the jet of water with reference
to its height from the ground;
• when the contents have been totally drained from the solution tank, close the drain
hose with the cock (fig. 16, ref. 3) screw-tightening it; check that it is perfectly closed
and refit the hose in its housing.
The water and detergent solution can also be used to wash the recovery tank.
If the machine is to remain unused for a long time, the squeegee and brushes (or drive
discs or rollers) must be dismounted, washed and kept in a dry place (preferably packed
in a plastic envelope or sheet), sheltered from dust. Park the machine with the parking
brake engaged.
Furthermore, make sure that the tanks are completely empty and perfectly clean.
Recharge the batteries completely before putting them in the storehouse. During long
periods of inactivity recharge the batteries (once every two months at least) to preserve
the storage batteries constantly at the maximum charge.
If the batteries are not recharged periodically, they may become damaged
8.
Do not check the battery charge by producing sparks.
The batteries give off inflammable vapours: put out any fire or embers before
Perform the operations described below in airy environments.
To avoid permanent damages to the batteries, never let them get flat completely.
Remember that when the proper red led (fig. 8, ref. 9) flashes on the control panel, it is
necessary to recharge the batteries.

Recharging procedures
Lead batteries with liquid electrolyte:
It is necessary to check the level of the electrolytic solution in order that it always covers
the films of the elements, adding the necessary distilled water.
During recharging do not let the temperature of the electrolyte exceed 45° C.
To recharge proceed as follows:
•
stop the machine and press the emergency button (fig. 8, ref. 2);
•
engage the parking brake by means of the pedal (fig. 8, ref. 12);
•
connect the battery-charger to the battery wiring connector (fig 17, ref. 1);
•
recharge according to the instructions written in the manual to the battery-charger;
•
switch off the battery charger before disconnecting the connectors;
