Battery

I DANGER
 Never touch the battery
electrolyte. The diluted sulphu-
ric acid solution burns skin and
make holes in clothing. Should
this occur, immediately wash
it off with plenty of clean water
and obtain medical assistance
without delay.
 Disconnect the battery leads
before carrying out any soldering
work on metallic hull.
Always read the manufacturer
recommendations before operating
the battery.
Battery should be kept clean and
dry. Oxidation or the deposit of
impurities on the battery and on its
terminals may lead to short cir-
cuits, voltage drops and premature
discharging, notably in wet weather.
Use a brass brush to clean battery
terminals.
When DISCONNECTING the
starter cables, always disconnect
FIRST the NEGATIVE LEAD (-),
and then the POSITIVE (+).
Always CONNECT FIRST the
POSITIVE LEAD (+) to the POSI-
TIVE TERMINAL (+) of the battery,
and then the NEGATIVE (-).
Use distilled water to top up the
electrolyte level. Follow in priority
the battery manufacturer instruc-
52
tions for topping up. If the battery
electrolyte level is not adjustable
(maintenance free battery type), do
not use or charge the battery if the
fluid level stands below the lower
limit level.
When adding electrolyte, unscrew
the vent plugs but leave them in
their holes.
I DANGER
Check that the battery compart-
ment is well drained and venti-
lated. When charging, battery
produces hydrogen which is
extremely explosive.
If the battery is replaced, use a
battery with similar specifications to
the previous one.
To simultaneously charge two
independent battery with a single
alternator, an isolator is available as
an option on most engines. Contact
an authorized Nanni dealer.
When storing the engine, adjust the
battery electrolyte level and store it
in a dry place. Recharge the battery
as often as possible to extend its
service life.
