INITIAL SETUP:
WARNING
• Battery acid (electrolyte) is extremely harmful. Always wear safety
goggles and rubber gloves, and do not smoke when performing battery
maintenance. Severe injury will result if acid contacts eyes or skin.
• Remove all jewelry such as rings, dogtags, bracelets, etc. If jewelry or
disconnected battery ground cable contacts battery terminal, a direct
short can result, causing instant heating of tools, severe injury to
personnel, or damage to equipment.
• Always disconnect both ground cables when performing battery
maintenance on the “A2” series vehicles. The “A2” series vehicles have
a 12 volt cable connected to the positive terminal, which keeps the
electrical system charged when only one ground cable is disconnected.
Failure to do this may cause injury to personnel, or damage to
equipment.
• When removing battery cable clamps, disconnect both ground cables
first. Ensure all switches are in OFF position before disconnecting. Do
not allow tools to come in contact with vehicle when disconnecting
cable clamps. A direct short can result, causing instant heating of
tools, tool damage, battery damage, or battery explosion.
NOTE
• Secure all cables to head side of mounting capscrews.
• Use this procedure for disconnecting all battery cables.
• The following procedure covers disconnection and connection of the
ground cable.
1.
Inspect cables (1), (2), and (11) for corrosion and cracks.
2.
Remove defective cables (1), (2), and (11), or clean with wire brush and baking soda solution.
