NOTICE: The battery electrolyte is dilute sulfuric acid. So, be careful
r
.
not to stain your body and clothes with it. If stained, rinse
portion in clean water.
Gravity conversion
The specified electrolyte temperature for the gravity measure-
ment is 20°C (68°F).
Measure the electrolyte temperature and do the conversion in
accordance with the following formula when the temperature
does not fall to the specified temperature.
30 = St + 0.0007 (t -20)
S20
; gravity at 20°C
St ; gravity measured
t ; electrolyte temperature whe measured
Battery terminal connections
Periodically, check. the battery terminals for loose connection
and corrosion.
For the check interval, follow the machine manufacturer’s
standard. Loose connection will cause hard engine starting or
deficient battery charging.
If the terminals are excessively corroded, disconnect the battery
cables and polish them with a wire brush or sandpaper.
Never reverse the “+” and “-”
terminals when reconnecting the
cables. Even a short period of reverse connection could damage
the electrical parts.
