Checking electrolyte level of battery cells
Check level of electrolyte in each cell every
50 hours. If low.
fill
to bottom of filler
necks with distilled water. Run engine for
a few minutes so that the water added can
mix with the electrolyte.

Checking specific gravity
of
battery electro-
lyte
The specific gravity of electrolyte is to be
checked by using an accurate hydrometer.
Charge battery if. reading is below 1.280 at
20°C (68°F).
Replace battery if difference between cells
is more than
0.050 (Specific gravity).
4)
Charging battery
Charge battery every 300 hours of opera-
tion.
When charging battery on
a
tractor, disconnect
positive battery cable to starter to avoid damage
the diodes of alternator.
Never apply
FAST CHARGE
to maintain long
life of battery.
a) Remove battery from tractor after discon-
necting ground cable, then positive cable.
b) Place the battery at the place where there is
plenty of ventilation.
C) Connect positive lead of charger to positive
pole of battery.
d) Connect negative lead of charger to nega-
tive pole of battery.
e) Select charging current according to speci-
A
fied value. It must not exceed specified
Max. current.
f) Switch on charger and check the current.
g) After charging for the required time, switch
off the charger.
h) Check specific gravity of electrolyte after
cooling electrolyte.
-
Charging time is determined by the state of charge
(Specific gravity of electrolyte). See instructions
of
battery charger or
YANMAR
dealer.
