Jump starting
If the 12-volt booster battery to be used is in another car, check that the cars are not touching to prevent
premature completion of a negative circuit. Note the position of the battery.
Using jumper cables:
●
First connect the booster battery positive (+) terminal (1) to car battery positive (+) terminal (2).
●
Then connect the booster battery negative (-) terminal (3) to a stationary solid metal part on the
engine at a point away from the battery (4).
Do not connect the jumper cable to any part of the fuel system or to any moving parts. Avoid touching
hot manifolds.
After the engine has started, first remove the negative (-) terminal jumper cable. Then remove the
positive (+) terminal jumper cable.
CAUTION: Improper hookup of jumper cables or use of other than 12-volt batteries could result in
damage to equipment and/or the battery.
WARNING!
●
Never expose the battery to open flame or electric spark.
●
Do not smoke near the battery.
●
Batteries generate hydrogen gas which is flammable and explosive.
●
Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or
painted surfaces. If contact occurs, flush the affected area immediately with water. Obtain medical
help immediately if eyes are affected.
Failure to follow the instructions for jump starting can lead to personal injury.
NOTE: Refer to
for information on properly maintaining the battery.
