given in the following table
This mixture can be permanently maintained in the circuit for 1 year so long as you have not
totalized 1000 hours service during this period. In this case, the mixture must be changed.
Flush out the system whenever you change from using pure water to antifreeze mixture and vice
versa.

ELECTRICAL SYSTEM Battery
Your tractor is equipped with a "Maintenance Free battery." Keep the battery clean and dry, particularly
on top. Check the electrolyte level: it should just touch the upper mark and never be under the bottom
mark. If necessary, open the cover and add distilled water.
WARNING : NEVER top up with SULPHURIC ACID.
Do not use quick battery chargers to recharge the Batteries.
Check the battery charge with a digital voltmeter as Described below:
Connect to the two battery poles, matching their terminals with the same sign (negative with negative
and positive with positive). Now read the measured value on the instrument;
Compare this value with the ones in the table to establish the battery charge status.
When the voltage is near 12.30V, the battery must be
immediately charged with current equal to 1/10 of the capacity
in Ah (a 65 Ah battery must be given a 5 Amp charge).
NOTE: If the battery must be topped up frequently or tends to
discharge, have the electrical system of your tractor checked
by your area Dealer's specialized personnel.
