personal injury (particularly to eyes) or property damage may result from
battery explosion, battery acid, or electrical (short circuit) burns.

THE MAJOR SAFETY PRECAUTION IS TO MAKE THE FINAL
CONNECTION TO GROUND (a solid, stationary metallic o b ject) ON
THE ENGINE AT SOME DISTANCE FROM THE BATTERY. THIS
HELPS REDUCE THE CHANCE OF AN EXPLOSION DUE TO
SPARKS.
•
To lessen the chance of an explosion, never expose the battery to
open flames or electric sparks. Also do not smoke near the battery.
Batteries give off a gas which is flammable and explosive.
•
To lessen the risk of injury in case an explosion does occur, wear
eye protection or shield your eyes when working near any
battery. Do not lean over a battery.
•
Do not allow battery fluid to contact eyes, skin, fabrics, or painted
surfaces because battery fluid is a corrosive acid. Flush any
contacted area with water immediately and thoroughly.
Also get medical help if eyes are affected.
•
To lessen the risk of a short circuit, remove rings, metal watch
bands and other metal jew.elry. Also do not allow metal tools to
contact at the same time the positive battery terminal (or any metal
connected to this terminal) and any other metal on either vehicle.
Make certain when attaching the jUmper cable clamps to the
positive terminals of the batteries that neither clamp contacts any
other metal.
This vehicle has a 1 2 volt battery and a negative ground electrical
1 .
system. Make sure that the other vehicle also has a 12 volt battery
and that the negative terminal is grounded (attached to a metal
part of the vehicle). Its owner's manual may give you that
information. If unsure of the other vehicle ' s voltage (or
if the voltage a nd ground on the other vehicle are
different from your vehicle), do not try to jump start as
personal injury or severe damage to electrical and
electronic parts may result.
Position the vehicle with the good (charged) battery so that the
