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 rol-
lers) 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 irreparably.
MAINTENANCE AND BATTERY RECHARGING
Do not check the battery charge by producing sparks.
The batteries give off inflammable vapours: put out any fire or embers before checking and
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, turn the main switch (fig. 8, ref. 13) to the "0" position (off) to disable all
the machine's functions;
►
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;
►
disconnect the battery charger connector from the battery wiring connector;
►
at the end of the recharging time check the battery intensity with a densimeter: if one or
more elements are flat and the remaining ones completely charged, the battery is dama-
ged and must be replaced.
Gel batteries:
Use only a battery-charger that is specific for gel storage batteries.
