If no audio alarm sounds, turn the rotary switch to the 12V position. The 3.10
clamps are now powered. Crank the engine. If the engine does not start
within 5 – 8 seconds, stop cranking and wait at least 1 minute before at-
tempting to start the vehicle again. (This permits the battery to cool down.)
After the engine starts, turn the rotary switch to the O (OFF) position. Then 3.11
disconnect the black clamp (-) and then the red clamp (+) in that order.
Store the clamps in the compartments located on the sides of the case.
Recharge the jump starter as soon as possible after use.3.12
*NOTE: In the rare case of jump-starting a vehicle that has a positive-
grounded vehicle electrical system, connect the NEGATIVE black clamp
(-) to the negative terminal (-) of the vehicle battery. Then connect the
POSITIVE 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. To
disconnect the clamps, reverse the order.
DIGITAL DISPLAY4.
The display can be used to indicate a battery’s voltage when connected to
a battery or the percentage of charge in the jump starter’s internal battery.
With the switch in the O (OFF) position, connect the clamps to the ve-
hicle’s battery, and its voltage is displayed. Turn the jump starter’s rotary
switch to 12V, and the combination of both internal and external batteries
are shown.
To read the internal battery’s charge status: disconnect the clamps from
the vehicle’s battery, with the switch in the O (OFF) position, press the
display button to read the percentage of charge left in the internal battery
or turn the switch to the 12V position, and the voltage level of the internal
battery is displayed. A fully charged battery will read 100% or 12.8 volts.
