ELECTRICAL SYSTEM
BATTERY -- Fig. 74
The tractors are fitted with maintenance--free
batteries.
Keep the top part clean and dry.
Check that the level of electrolyte reaches the top
mark and never falls below the lower mark.
If necessary lift covers (1) and add distilled water.
CAUTION
Never top up the battery with SULPHURIC ACID.
Never use rapid ”boost” battery chargers to recharge
the battery.
Check the charge with a digital voltmeter in the
following way:
-- connect the voltmeter to the battery’s two
terminals, matching the terminal symbols
(negative to negative and positive to positive)
and read the value from the instrument;
-- compare the figure with the values in the table
below to establish the charge in the battery.

If the voltage is around 12.30 V or lower, immediately
recharge the battery with a current equivalent to

NOTE: If the battery frequently needs to be topped
up or if it should tend to run down, have the electrical
system of your tractor checked by your dealer.

CAUTION
Before recharging the battery, always disconnect the
cables. The battery should be removed from its
location and recharged at a safe distance from the
tractor.
DANGER
When recharging the battery, keep the premises well
ventilated and keep naked flames or cigarettes well
away.
NOTE: Batteries and storage batteries contain
components that may be damaging to the
environment if incorrectly disposed of after use. The
manufacturer strongly advises that all “dry” batteries,
used in electrical or electronic syst ems, are returned
to your authorised dealer. The dealer will dispose of
(or recycle) the batteries correctly. This procedure is
a legal requirement in certain countries.
NOTE: If it is necessary to replace the old battery
with a new one proceed as follows:
-- First disconnect the lead end marked with a
negative sign (--), then the lead end with the
positive sign (+);
-- Fit the new battery in the correct position. Do not
over--tighten the retaining screws;
-- Clean the lead ends and connect them to the
battery terminals, ensuring that the negative
terminal (--) is connected last;
-- Fully tighten the lead ends on the terminals and
smear them with petroleum jelly.
