Caution: Booster battery voltage must be 12V. Do not start with booster battery unless you are sure it is the right battery.
1. Turn off all unnecessary lights and make sure the cars are not touching.
2. If necessary, remove all vent plugs from booster and dead batteries. Lay a cloth over the open vents on the batteries (this helps to reduce the risk of explosion).
3. If the booster battery vehicle does not run, start it and let it run for a few minutes. When starting with a booster battery, the engine should run at approximately 2000 rpm.
4. Connecting cables.
A) Connect the cables in the sequence shown in the figure.
Note: To avoid serious injury when making connections, do not lean over the battery or allow the cables or clamps to accidentally touch anything other than the appropriate battery terminals or ground.
b) Attach the clamp on the other end of the negative booster battery cable to a rigid, non-moving, unpainted metal part of the vehicle's engine with the dead battery as shown.
Attention: do not connect the cable near any part that can move when the engine is cranked.
5. Start the engine in the usual way. Once started, it should run at 2000 rpm for a few minutes.
6. Carefully disconnect the cables, negative first, then positive.
7. Carefully remove fabrics covering batteries as they may contain sulfuric acid.
8. If the vent plugs have been removed, reinstall them.
