Battery
Batteries in Cold Weather
In colder weather a greater drain is placed on the batteries when
th
ey are used for the preheat cycle and when starting a cold
engine. Battery performance decreases as the temperature gets
lower.
In extremely cold weather, remove batteries at night and move
them to a
warm location. This will help to keep them at a higher
power level.
WARNING
AVOID DEATH OR SERIOUS INJURY
Battery electrolyte contains sulfuric acid and can quickly
burn t
he skin and eat holes in clothing. If you spill acid on
yourself, immediately flush the area with water.
Battery acid could cause blindness if splashed into the
eyes. If
acid gets into the eyes, flush them immediately with
large quantities of water and see a doctor at once.
If you accidentally drink acid, drink a large quantity of water
or milk, be
aten egg or vegetable oil. Call a doctor or poison
prevention center immediately.
When working with batteries, always wear safety glasses or
goggle
s.
Battery generates hydrogen gas, so there is danger of an
explo
sion. Do not bring lighted cigarettes near the battery,
or do anything that will cause sparks.
Before working with batteries, stop engine and turn the
start
er switch to "O" (OFF) position.
Avoid short circuiting the battery terminals through
accident
al contact with metallic objects, such as tool.
When removing or installing, check which is the positive (+)
termin
al and negative (-) terminal.
When removing the battery, first disconnect the negative (-)
termin
al. When installing the battery, first connect the
positive (+) terminal.
If the terminals are loose, there is danger that the defective
cont
act may generate sparks that will cause an explosion.
When installing the terminals, install them tightly.
