Sears 200.71486 manual Powering a 12v dc device

4.4Connect the red clamp to the positive (+) terminal of the vehicle battery.

4.5Connect the black clamp to an unpainted and unmoving part of the vehicle chassis or engine block. Do not connect to the carburetor, fuel lines or sheet-metal body parts.

CAUTION: If you have connected the clamps backwards, an audio alarm will sound. DO NOT turn the ON/OFF switch to the ON position. This could cause serious damage. Reverse the connections and the audio alarm will stop.

4.6Turn the jump start ON/OFF switch to the ON position.

4.7Turn the key and crank the engine. If the engine does not start within 5-8 seconds, stop cranking and wait at least 1 minute before attempting to start vehicle again. This permits the battery to cool down.

4.8After the engine starts, turn the JUMP START ON/OFF switch to OFF.

4.9Disconnect the black clamp first and then the red clamp. Store the clamps on the ears located on the back of the case.

4.10Charge the 750 as soon as possible after jump-starting.

CAUTION: To prevent sparking while the 750 jump-start switch is in the ON position, NEVER allow the clamps to touch together or to contact the same piece of metal. And, never attempt to charge a frozen battery.

NOTE: In the rare case of jump-starting a vehicle that has a positive- grounded vehicle electrical system, connect the black clamp to the negative terminal of the vehicle battery. Then connect the red clamp to an unpainted and unmoving part of the vehicle chassis or engine block. If you are unsure of the nature of the vehicle’s electrical grounding system, check the owner’s manual of the vehicle or call the Customer Technical Assistance number: 1-800-SEARS-64.

The Portable Power 750 is a power source for all 12 volt DC accessories that are equipped with a 12V accessory plug. The DC accessory outlet has a 15-amp automatic overload protection circuit breaker. The breaker will automatically reset after an overload occurs.

To operate a 12V DC device:

5.1Open the protective cover of the DC power outlet on the right side of the Portable Power 750.

5.2Plug the 12V DC device into the DC power outlet, and turn on the 12V DC device (if required).

5.3If the 12V DC device draws more than 15A, the internal circuit breaker of the Portable Power 750 will momentarily disconnect power to the device. If this occurs, unplug the device and the circuit breaker will automatically reset after several seconds.
