OPERATING INSTRUCTIONS

JUMP STARTING A VEHICLE
6.1
IMPORTANT: Using the jump starter without a battery installed in the vehicle will damage the vehicle's electrical system.
1. Turn the ignition OFF.
2. Lay the DC cables away from any fan blades, belts, pulleys, and other moving parts.
NOTE: Make sure all of the vehicle's electrical devices are turned off.
3. For a negative-ground vehicle (as in most vehicles), connect the jump starter's POSITIVE (RED) clamp to the POSITIVE (POS, P, +) battery post. Next, connect the
NEGATIVE (BLACK) clamp to the vehicle chassis or engine block, away from the battery.
4. For a positive-ground vehicle, connect the jump starter's NEGATIVE (BLACK) clamp to the NEGATIVE (NEG, N, -) battery post. Next, connect the POSITIVE (RED)
clamp to the vehicle chassis or engine block away from the battery.
5. Press the Jump start/Override button to turn on the jump starter. The green Ready LED will light.
6. It is best to wait 30 seconds after clamp connection to attempt to start the vehicle. Crank for up to 5 seconds. If engine does not start, wait 30 seconds before cranking again.
7. After the engine starts, press the Jump start/Override button to turn the jump starter off, and then disconnect the black clamp (-) and the red clamp (+), in that order.
8. Recharge the unit as soon as possible after each use. NOTE: Recharge the unit when all Battery Status LEDs are off.
STARTING A BATTERY WITH LOW VOLTAGE
6.2
If the vehicle's battery voltage is too low for the jump starter to detect that the clamps are connected, there is a manual start procedure to enable the jump start function.
1. Make sure the clamps are correctly connected.
2. Press the Jump start/Override button once then press and hold for 5 seconds, to turn on the override mode. The green Ready LED will flash.
WARNING! This overrides a safety feature. It will energize the clamps and cause sparking if they are touched together. If the clamp connections are shorted or reversed,
damage to the unit, battery, and possibly the car's electrical system will occur.
USING THE USB PORT
6.3
The USB port provides up to 2.4A at 5V DC.
1. Ensure the battery clamps are securely clipped on the storage holders.
2. Press the Power button on the front of the unit to turn on the power.
3. Plug your device into the USB port.
4. Turn on the USB device, if necessary.
5. When finished using the USB port, turn off the device (if necessary) and unplug the device.
6. Recharge the unit as soon as possible after each use. NOTE: Recharge the unit when all Battery Status LEDs are off.
USING THE WORK LIGHT
6.4
1. Position the jump starter on a flat, stable surface near the intended work area.
2. Ensure the battery clamps are securely clipped on the storage holders.
3. Press the Light button on the front of the unit and hold for 0.75 second, to cycle through the following modes:
• Steady glow
• Flash for an SOS signal
• Flash in strobe mode
4. When finished using the work light, press and hold the button for 0.75 second, to turn off the work light.
5. Recharge the unit as soon as possible after each use.
