6.2 CHARGING THE INTERNAL BATTERY
NOTE: Use a 2A USB charger (sold separately), or a 2A USB
charging port to quickly recharge the jump starter. Using a charger
with less than 2A will increase charge time.
1. Plug the Micro USB end of the charging cable into the input port. Next,
plug the USB end of the charging cable into a charger's USB port.
2. Plug your charger into a live AC or DC power outlet.
3. The LCD display will light, the digit begins to flash and show "IN", indicating
that charging has begun.
4. The jump starter will fully charge in 4-5 hours. When the unit is fully
charged, the display will show "100%".
5. When the battery is fully charged, disconnect your charger from the
outlet, and then remove the charging cable from the charger and the
unit. Slide the ON/OFF switch to the OFF position, if you are not using
the unit immediately.
7. OPERATING INSTRUCTIONS
7.1 JUMP STARTING A VEHICLE ENGINE
NOTE: Use only model number SA883 jump cable.
IMPORTANT: Do not use the jump starter while charging its internal battery.
IMPORTANT: Using the jump starter without a battery installed in the
vehicle will damage the vehicle's electrical system.
NOTE: The internal battery must have a charge if at least 40% to
jump start a vehicle.
1. Turn the ignition OFF.
2. Plug the battery clamp cable into the jump starter's output socket.
3. Lay the DC cables away from any fan blades, belts, pulleys and other
moving parts. Make sure all of the vehicle's electrical devices are turned off.
4. 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.
5. 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.
6. Slide the ON/OFF switch to the ON position. The green LED on the
smart cable should light.
NOTE: If the vehicle battery is extremely discharged, the initial current
draw from the jump starter may activate short circuit protection in the
smart cable. When the condition is corrected, the smart cable will
automatically reset.
7. After a proper connection has been made, 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.
