Electrical system
In the event of accidental ingestion of the fluid, immediately drink large quantities of water or milk. Follow
with milk of magnesia, beaten egg or vegetable oil. Seek immediate medical attention
Batteries produce explosive gases; keep clear of free flames, sparks or cigarettes; ventilate the area
when recharging the battery indoors.
Always protect your eyes when working close to batteries.
Keep out of the reach of children.
The battery is an electrical device which requires
careful monitoring and diligent maintenance. The
maintenance rules are:
1) Check the level of the electrolyte
The electrolyte level must be checked frequently
and must reach the upper level. Only use distilled
water, to restore this level.
If it is necessary to add water too frequently, check
the vehicle's electrical system: the battery works
overcharged and is subject to quick wear.
2)Load status check
After restoring the electrolyte level, check its den-
sity using an appropriate densitometer (see the
figure).
When the battery is charged, you should detect a
density of 30 to 32 Bé corresponding to a specific
weight of 1.26 to 1.28 at a temperature of no lower
than 15° C.
A density reading of less than 20° Bé indicates that
the battery is completely flat and it must therefore
be recharged.
After charging the battery, check each element
electrolyte level and density. If the scooter is not
used for a given time (1 month or more) it will be
necessary to periodically recharge the battery.
The battery runs down completely in the course of
three months.
If it is necessary to refit the battery in the vehicle,
be careful not to reverse the connections, remem-
bering that the earth wire (black) marked (-) must
be connected to the - negative terminal while the
other two red wires marked (+) must be connected
to the terminal marked with the + positive sign.
