7 - MAINTENANCE
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 sys-
tems, are returned to your local dealer. The dealer will dispose of (or recycle) the batteries correctly. This procedure
is requested by law in certain countries.
If an old battery needs to be replaced 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 seat, without over- tightening the retaining screws;
• clean the lead ends and connect 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.
ADVICE ON STARTING THE ENGINE WITH A FLAT BATTERY OR NO BATTERY
To prevent damage to the alternator and its incorporated regulator follow the procedure below.
When the tractor battery is partially discharged, and an auxiliary battery has to be used to start the engine, connect
the battery to the tractor battery ensuring that the terminals match (positive to positive and negative to negative).
This rule must also be observed when recharging the battery externally.
If you have to start the engine with a totally flat battery or where the tractor does not have a battery remember that:
• it is not possible to jump start the tractor by towing, as the electro--magnetically operated injection pump cut--off
device will prevent the engine from starting;
• it is possible to start the tractor with an auxiliary battery after having first disconnected plug
D+ , terminal B+ and
the condenser but to no avail given that the engine will stop as soon as the external battery supply to the electro-
magnetic cut--off device is interrupted;
• avoid starting the engine with an auxiliary battery whilst plug
D+ , terminal B+ and the condenser are connected to
the alternator;
• however, it is necessary to connect a
12 V battery, capable of starting the tractor, and then to replace it with the
battery that is to be fitted on the tractor.
• Under normal conditions, the engine must never run without plug
D+ , terminal B+ and the condenser disconnected
from the alternator.
