3. Turn off the vehicle ignition and accessories (e.g. radios, lights, air conditioners), and
disconnect all devices such as GPS and mobile phones or tablets.
4. Turn off all Battery Jumper switches and disconnect all accessories.
5. Determine the polarity of the vehicle’s battery terminals. The positive (POS, P, +) battery
terminal is usually larger in diameter than the negative (NEG, N, −) terminal. If you are
unsure, you should refer to the vehicle owner’s manual.
6. Determine the ground system of your vehicle.
• If vehicle to be started has a negative ground system (this is most common):
a. Connect the red (+) cable clamp first to the vehicle’s positive (red) battery terminal.
b. Next, connect the black (−) clamp to the vehicle chassis or a solid, non-moving,
metal vehicle component or body part. DO NOT clamp directly to negative battery
terminal or a moving part.
• If vehicle to be started has the positive battery terminal connected to chassis (this is rare
and usually found in older car models from the 1950s or earlier):
a. Connect the black (−) clamp first to vehicle battery’s negative (black) terminal.
b. Connect red (+) clamp to vehicle chassis or a solid, non-moving, metal vehicle
component or body part. DO NOT clamp directly to positive battery terminal or a
moving part.
7. Inside the vehicle, turn on the ignition switch and attempt to start the engine.
8. Crank a maximum of 3 seconds. If the engine does not start, wait 3 minutes before the
next attempt.
9. After the engine starts, disconnect the clamps in the reverse order of connection prior
to jumpstarting.
10. Be sure that the cables and clamps are securely stored.
11. Recharge the Battery Jumper as soon as convenient.
AIR COMPRESSOR
This Battery Jumper is equipped with an air compressor that can provide up to 260 PSI (pounds
per square inch) of pressure for a variety of uses such as vehicle tires and sports equipment.
CAUTION:
Be careful not to over inflate, monitor the compressor gauge while inflating. Never
connect or disconnect the nozzle with the compressor operating.
Procedure
In the event that the vehicle tire is completely flat, raise the vehicle using a recommended jack
before inflating the tire.
1. Before any tire inflation, look for manufacturer’s recommended inflation pressure.
2. Unwind and extend the air hose from the bottom, back side of the unit.
3. Position the Battery Jumper so that you can see the pressure gauge.
4. Make sure the chuck lever is positioned up (away from the chuck opening).
5. Determine if you will need an air hose adapter for your object.
