JUMPSTARTER
WARNING
Failure to follow these instructions may cause damage or explosion�
• Jumpstart connection is ALWAYS live! Never allow the clamps to touch together or contact
the same piece of metal.
• Do not attempt to jumpstart your vehicle when battery bank is below 20% charge (observe
battery status indicator lights on the unit).
• Only use with positive grounded systems.
• Do not reverse jumper cables.
• Use safety glasses to protect eyes while jumpstarting a battery.
• If the engine fails to start after two attempts, discontinue jumpstart procedure. Excessive
engine cranking can damage the vehicle's starter motor. Look for other problems that may
need to be corrected or call for professional service.
• Disconnect the clamps from the vehicle battery immediately after engine starts. Return the
cable clamps to their storage holsters when not in use.
• Vehicles equipped with on-board computers may be affected if the engine battery is
jumpstarted. Read your vehicle owner's manual before attempting to start the vehicle to
determine if external starting assistance can be used.
• If the battery bank is overloaded while in the jumpstart mode, quickly disconnect the clamps
and let the unit rest for ten minutes then plug it into a power source for a few minutes to reset
the unit. All functions on the battery bank will not operate until this is done.
Procedure
1. Turn off the vehicle ignition and all accessories (radios, lights, air conditioners), and
disconnect electronic devices.
2. Set the emergency brake and put vehicles with automatic transmission in park position.
3. Determine the polarity of the vehicle's battery terminals. The positive (POS, P, +) battery
terminal usually is red and larger in diameter than the negative (NEG, N, −) terminal. If you
are unsure, first refer to the vehicle owner's manual.
4. Remove clamps from the holders. Never allow clamps (positive & negative terminals) to
touch together or contact the same piece of metal to prevent short-circuits and arcing. Insert
the blue plug of the jumper cables into the battery bank's jumper terminal.
5. Securely connect the positive (+) red clamp to the positive (POS, P, +) terminal of the vehicle
battery or the remote positive (+) terminal if equipped.
6. Securely connect the negative (−) black clamp to the negative terminal.
7. Place unit on a secure surface away from moving parts.
8. Start vehicle engine. Stop if the vehicle does not start after 4 to 5 seconds of engine
cranking. Disconnect the cables and wait 3 to 4 minutes, then try again. If engine does not
start after second attempt, discontinue and consult a professional.
9. When finished, disconnect the clamps in reverse sequence of connecting procedure—first
disconnect negative (black), then positive (red) clamps.
