time. Excess grease may cause grease seals to fail or grease migration into areas

Batteries and Charging
Safety
• NOTE:
Always observe the following warnings when working on or near
batteries.
• WARNING:
To prevent battery explosion that could result in severe per-
sonal injury or death, keep all smoking materials, open flame or sparks
away from the batteries.
•
Hydrogen gas is formed when charging batteries. Do not charge batteries
without adequate ventilation. A 4% concentration of hydrogen gas is ex-
plosive.
•
Be sure that the key switch is off and all electrical accessories are turned
off before starting work on vehicle.
•
Never disconnect a circuit under load at a battery terminal.
•
Batteries are heavy. Use proper lifting techniques when moving them. Al-
ways lift the battery with a commercially available battery lifting device.
Use care not to tip batteries when removing or installing them; spilled
electrolyte can cause burns and damage.
•
The electrolyte in a storage battery is an acid solution which can cause
severe burns to the skin and eyes. Treat all electrolyte spills to the body
and eyes with extended flushing with clear water. Contact a physician im-
mediately.
•
Always wear a safety shield or approved safety goggles when adding water
or charging batteries.
•
Any electrolyte spills should be neutralized with a solution of 1/4 cup (60
mL) sodium bicarbonate (baking soda) dissolved in 1½ gallons (6 liters) of
water and flushed with water.
•
Overfilling batteries may result in electrolyte being expelled from the bat-
tery during the charge cycle. Expelled electrolyte may cause damage to
the vehicle and storage facility.
•
Aerosol containers of battery terminal protectant must be used with ex-
treme care. Insulate metal container to prevent can from contacting bat-
tery terminals which could result in an explosion.
•
Wrap wrenches with vinyl tape to prevent the possibility of a dropped
wrench from ‘shorting out’ a battery, which could result in an explosion
and severe injury or death.
