MAINTENANCE
BATTERY MAINTENANCE
Mishandling of the battery shortens the service life of the
battery and adds to maintenance cost. When handling the
battery do the following:
Be careful to not let the battery electrolyte come in
contact with your body or clothing.
ALWAYS wear eye protection and rubber gloves, as the
battery contains sulfuric acid which burns skin and eats
through clothing.
Check the battery terminals periodically to ensure that
they are in good condition.
Use wire brush or sand paper to clean the battery
terminals.
ALWAYS check the battery for cracks or any other
damage. If a white pattern appears inside the battery or
paste has accumulated at the bottom, replace the battery.
DANGER
Use all safety precautions specified by the battery
manufacturer when working with the battery.
Flammable, explosive gas. (Produces
hydrogen gas while charging or during
operation.) Keep the area around the
battery well ventilated and keep away from
any fire source.
Battery electrolyte contains corrosive, toxic
chemical (dilute sulfuric acid). Avoid
contact with eyes and skin.
Shock or fire due to electrical short
circuit. Disconnect battery cables before
inspecting the electrical system. NEVER
‘spark’ battery terminals to test for charge.
CAUTION
Battery Safety
Wear safety glasses or face mask, protective clothing,
and rubber gloves when working with the battery.
NEVER attempt to charge a battery that is frozen. The
battery can explode unless first allowed to thaw.
If the pump will not be in operation for a long period of
time, store it in a cool, dry place and check the battery
charge level every month to maintain the performance
of the battery.
Check the battery regularly and make sure that the
electrolyte level is to the bottom of the vent well
(Figure 53). If necessary add only distilled water in a
well-ventilated area. Never operate or recharge without
sufficient fluid in the battery.
