OPERATING INSTRUCTIONS

6.1 Jump Starting a Vehicle Engine
1. Turn vehicle's ignition OFF before making cable connections.
2. If the jump starter is plugged into a 120V AC wall outlet, disconnect it.
Never use the jump starter while the charger is connected or you may
damage the jump starter or cause property damage.
3. For a negative grounded system, clamp the red clip (+) to the positive
terminal of the battery.
4.
Clamp the black clip (-) to an unpainted and unmoving part of the chas-
sis or engine block.
NOTE: In the rare case of jump-starting a vehicle that has a positive-
grounded vehicle electrical system, connect the NEGATIVE black clip (-)
to the negative terminal (-) of the vehicle battery. Then connect the POSI-
TIVE red clip (+) 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. To disconnect
the clips, reverse order.
5. 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 the
vehicle again. (This permits the battery to cool down.)
6. After the engine starts, disconnect the black clip (-) and then the red
clip (+) in that order.
7. Recharge the jump starter as soon as possible after use.
Risk of Explosion.
To prevent sparking, NEVER allow the clips to touch together or
to contact the same piece of metal. Never attempt to jump start a
frozen battery.
6.2 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. Use it for power outages and fishing
or camping trips. Estimated usage time is listed in the chart below.
Make sure the device to be powered is OFF before inserting the 12V DC
accessory plug into the 12V DC accessory outlet.
1. Ensure the battery clips are securely clipped on the storage holders.
2. Open the protective cover of the DC power outlet on the front of the
jump starter.
3.
Plug the 12V DC device into the DC power outlet, and turn the 12V DC
device on (if required).
4. If the 12V DC device draws more than 15A or has a short circuit, the
internal circuit breaker of the jump starter will trip and disconnect the
power to the device. Disconnect the 12V DC device. The breaker will
automatically reset after an overload occurs.
