BATTERY CHARGING AND MAINTENANCE
Safety
Always obey the following warnings when working on or near batteries.
To prevent the risk of battery explosion, keep all flammable materials, open flames or sparks away
from the batteries.
Hydrogen gas is made as batteries are charged. Do not charge batteries without good ventilation.
A 4% concentration of hydrogen gas is explosive.
Make sure that the key switch is in the OFF position and all electrical accessories are off before
you start to work on the vehicle.
Turn off all accessories before disconnecting from the battery terminal.
Use safe procedures to move the batteries. Always lift the battery with a
commercially available battery lifting device.
Do not tilt the batteries during removal or installation. An electrolyte spill can
cause burns and damage.
The electrolyte in a storage battery is an acid solution which can cause
burns to the skin and eyes. Treat all electrolyte spills to the body and eyes
with extended flushing with clear water. Contact a physician immediately.

Unless otherwise noted in text, tighten all hardware in accordance with this chart.
This chart specifies 'lubricated' torque figures. Fasteners that are plated or lubricated when
installed are considered 'wet' and require approximately 80% of the torque required for 'dry' fasteners.
