Battery
Check electrolyte level weekly. Electro-
lyte level must be at upper level line on
battery casing.
If necessary add distilled water. Bat-
tery connections must also be free of
corrosion. If cleaning is necessary, re-
move corrosion using a stiff brush then
clean with a solution of baking soda
and water. Rinse and dry well.
. . , CAUTION: Do not allow cleaning
~
solution to enter battery. It will
destroy the chemical properties of the
electrolyte.
After reconnecting battery, coat bat-
tery termi.nals and connectors with pe-
troleum Jelly to
prevent corrosion.
Check that battery overflow tube is not
blocked or linked.
.... WARNING: Overflow tube must
T
be free and open. A kinked or
bent tube will restrict ventilation and
create gas accumulation that could re-
sult in an explosion. Avoid skin contact
with electrolyte.
. . , CAUTION: Prior to charging the
~
battery, always remove it from
the vehicle to prevent electrolyte spill-
age.
Suspension
