• Always disconnect the negative (black) jumper cable first, followed by
the positive (red) jumper cable, except for positive grounded systems.
PROCEDURE
Take the following steps, observing all cautions and warnings in the
"Important Safety Instructions" section at the front of this manual.
1. Turn off vehicle ignition and all accessories (radio, A/C, lights,
connected cell phone chargers, etc.). Place vehicle in "park" and
set the emergency brake.
2. Make sure the jump-starter power switch is in the off position.
3. Remove jumper clamps from clamp tabs. Connect the red clamp
first, then the black clamp.
4. Procedure for jump-starting a NEGATIVE GROUNDED
SYSTEM (negative battery terminal is connected to chassis)
(MOST COMMON)
4a. Connect positive (+) red clamp to vehicle battery's positive
terminal.
4b. Connect negative (–) black clamp to chassis or a solid, non-
moving, metal vehicle component or body part. Never clamp
directly to negative battery terminal or moving part. Refer to
the automobile owner's manual.
5. Procedure for jump-starting POSITIVE GROUND SYSTEMS
NOTE: In the rare event that the vehicle to be started has a
Positive Grounded System (positive battery terminal is connected
to chassis), replace steps 4a and 4b above with steps 5a and 5b,
then proceed to step 6.
5a. Connect negative (–) black clamp to vehicle battery's negative
terminal.
5b. Connect positive (+) red clamp to vehicle chassis or a solid,
non-moving, metal vehicle component or body part. Never
clamp directly to positive battery terminal or moving part. Refer
to the automobile owner's manual.

6. When the clamps are connected properly, the backlit LCD screen
will display the following to indicate the unit is ready to jump-start:
The Battery Status icon, Battery Voltage Indicator, Clamp Icons
and the "+" and"–" signs light solid. The jump starter icon will flash
to indicate the clamps are properly connected.
7. Turn the Jump-Starter Power Switch on. Turn on the ignition and
crank the engine in 5-6 second bursts until engine starts. The
backlit LCD screen will display the following:
The Battery Status Icon, the Battery Voltage Indicator, Clamp
Icons and the "+" and "–" signs light solid to indicate the unit is
jump-starting. The Jump Starter Icon flashes. The Jump Starter
Icon lights solid once the vehicle starts.
8. The Jump Starter Icon flashes, then lights solid if the vehicle has
started.
9. Turn the Jump-Starter Power Switch off.
10. Disconnect the negative (–) engine or chassis clamp first, then
disconnect the positive (+) battery clamp.
IMPORTANT: Always turn the unit off when not in use. Recharge this
unit fully after each use.

CAUTION – TO REDUCE THE RISK OF PROPERTY DAMAGE:
• Vehicles that have on-board computerized systems may be damaged
if vehicle battery is jump-started. Before jump-starting this type of
vehicle, read the vehicle manual to confirm that external-starting
assistance is advised.
• Excessive engine cranking can damage the vehicle's starter motor. If
the engine fails to start after the recommended number of attempts,
discontinue jump-start procedure and look for other problems that
need to be corrected.
• If vehicle fails to start, turn off the ignition, turn off the Jump-Starter
Power Switch, disconnect the jump-start system's leads and contact
a qualified technician to investigate why the engine did not start.
Alternator Check
Set up the unit and connect to the battery following steps 1 through 5
in the "Jump-Starter" section.
Important Notes About the Alternator Check Function
1. The unit may detect that the alternator is out of typical voltage
range because someone has added a number of accessory loads
on the charging system, thereby increasing current demand from
the alternator. MAKE SURE THAT THE ALTERNATOR IS RATED
TO SUPPORT THE APPLICATION.
2. This check may not be accurate for every make, manufacturer and
model of vehicle. Check only 12 volt systems.
PART 1
No Load (turn OFF all vehicle's accessories): The vehicle battery
must be fully charged before testing the alternator. Run the engine
long enough to achieve normal idle speed and verify there is a no-load
voltage.
1. Press the Alternator Check Button to start the check. The backlit
LCD screen will display the following to indicate the unit is analyzing
the alternator:
The Battery Status Icon will light solid and the Alternator Icon will
flash.
2. If the unit detects that the alternator is good, the backlit LCD screen
will display the following:
The Battery Status Icon, Alternator Icon, and "ALT GOOD" will light
solid.
3. If the unit detects that the alternator is out of typical voltage range,
the backlit LCD screen will display the following:
