Battery Service

IMPORTANT: To prevent damage to the electrical
components, do not operate the engine with the bat-
tery cables disconnected.
Keep the terminals and entire battery case clean. To
clean the battery, wash the entire case with a solution of
baking soda and water. Rinse with clear water. Do not
get the soda solution into the battery because damage
to the battery will result. Coat the battery posts and cable
connectors with skin–over grease, or petroleum jelly to
prevent corrosion.
Check for loose battery hold–downs. A loose battery
may crack or cause the container to wear and leak acid.
Check the electrolyte solution to make sure the level is
above the plates. If the level is low (but above the plates
inside the battery), add water so the level is to the bottom
of the cap tubes. If the level is below the plates, add wa-
ter only until the plates are covered and then charge the
battery. After charging, fill the battery to the proper level.
Do not charge a frozen battery because it can
explode and cause injury. Let the battery
warm to 60 F (15.5 C) before connecting to
a charger.
Charge the battery in a well–ventilated place
so that gases produced while charging can
dissipate. Since the gases are explosive,
keep open flame and electrical spark away
from the battery; do not smoke. Nausea may
result if the gases are inhaled. Unplug the
charger from the electrical outlet before con-
necting or disconnecting the charger leads
from the battery posts.
