3. Stay clear of fan blades, belts, pulleys and other parts that can cause injury. NOTE: If it is necessary to close the hood during

the jump starting process, ensure that the hood does not touch the battery clamps or cut the insulation of the cables.

4. Check the polarity of the battery posts.

5. Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded to the

chassis (as in most vehicles), see step 6. If the positive post is grounded to the chassis, see step 7.

6. For a negative-grounded vehicle, connect the POSITIVE (RED) clamp from the jump starter to the POSITIVE (POS, P, +)

ungrounded post of the battery. Connect the NEGATIVE (BLACK) clamp to the vehicle chassis or engine block away from the

battery. Do not connect the clamp to the carburetor, fuel lines or sheet-metal body parts. Connect to a heavy gauge metal

part of the frame or engine block.

7. For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clamp from the jump starter to the NEGATIVE (NEG, N, -)

ungrounded post of the battery. Connect the POSITIVE (RED) clamp to the vehicle chassis or engine block away from the

battery. Do not connect the clamp to the carburetor, fuel lines or sheet-metal body parts. Connect to a heavy gauge metal

part of the frame or engine block.

8. Crank the engine. If the engine does not start within 10 seconds, stop cranking and wait at least 1 minute before

attempting to start the vehicle again. (This permits the jump starter battery to cool down.)

9. After the engine starts, disconnect the black clamp (-) and then the red clamp, (+) in that order (for a negative-grounded vehicle).

10. Recharge the jump starter as soon as possible after use.

Powering a 12V DC device

•

The jump starter is a power source for all 12V DC accessories that are equipped with a 12V accessory plug.

CAUTION: Do not use the jump starter to run appliances that draw more than 15A DC.

NOTE: Extended operation of a 12V DC device may result in excessive battery drain. Recharge the jump starter immediately

after unplugging the 12V DC device.

NOTE: Do not power a 12V device with the jump starter while charging the internal battery.

1. Make sure the device to be powered is OFF before inserting the 12V DC accessory plug into the 12V DC accessory outlet.

2. Open the protective cover of the DC power outlet on the jump starter.

3. Plug the 12V DC device into the DC power outlet and turn on the 12V DC device (if required).

4. When finished, turn off the DC device (if required) and unplug from the DC power outlet.

FUSE REPLACEMENT

The jump starter is equipped with a replaceable fuse, to protect the battery from overload.
