JUMP STARTING (BATTERY BOOST) INSTRUCTIONS
CAUTION: Follow correct polarity connection and never allow booster clamps to touch together or to contact the same
piece of metal to prevent short circuits and arching.
1. Turn off the vehicle ignition and all accessories (e.g., radios, lights, air conditioner and cellular phones).
2. Set the emergency brake and put vehicle with automatic transmission in the PARK position.
3. Determine the polarity of the vehicle battery terminals. The Positive (POS, P, +) battery terminal usually is
larger in diameter than the Negative (NEG, N, -) terminal. (If you are unsure you should refer to vehicle
owner's manual).
4. Determine whether your vehicle uses a Negative or Positive Grounded System:
Negative Grounded System: Negative battery terminal is grounded to chassis. Most vehicles use this system.
Positive Grounded System: Positive battery terminal is grounded to chassis or any other metallic part of the
vehicle (If you are unsure you should refer to the vehicle owner's manual).
5. Access the jump starter booster clamps by squeezing the clamp handles. Pull the clamps outward and
remove clamps from their storage holders. Never allow clamps to touch together or to contact the same
piece of metal to prevent short circuits and arching.
6. Follow instructions for Negative Grounded System or Positive Grounded System as indicated below:
Negative Grounded System:
a. Securely connect the Positive (+) Red clamp to the Positive (POS, P, +) terminal of the vehicle battery or
the remote Positive (+) terminal if equipped.
b. Securely connect the Negative (-) Black clamp to the vehicle chassis, engine block or a thick non-moving
grounded metal part of the vehicle as far away from the battery as possible. Do not clamp directly to
carburetor, fuel lines, or non-grounded sheet-metal body parts.
c. See Jump Starting (Battery Boost) step #7 to continue.
Positive Grounded System:
a. Securely connect the Negative (-) Black clamp to the Negative (NEG, N, -) ungrounded terminal of the
vehicle battery.
b. Securely connect the Positive (+) Red clamp to the vehicle chassis, engine block or a nonmoving grounded
metal part of the vehicle as far away from the battery as possible. Do not clamp directly to carburetor, fuel
lines, or Sheet-metal body parts.
c. See Jump Starting (Battery Boost) step #7 to continue.
NOTE: Unit should detect 12V or 24V battery voltage on vehicle. If the battery is severely discharged, 12V and/or 24V
LED will be flashing. Stop the process immediately and disconnect clamps. Check vehicle manual to identify battery
voltage. User must manually select 12V or 24V battery until the proper LED is illuminated. Then connect clamps based
on Positive or Negative Ground System (step #6) and proceed to step #7.
NOTE: DO NOT start vehicle until you check all connections. Make sure correct positive and negative polarity
connections are achieved when using manual voltage selection for 12V or 24V to avoid damage to unit and/or vehicle
battery.
7. Allow 2 or 3 minutes charging time. It is recommended to have a second person to assist holding the jump
starter unit securely in place during the next steps.
8. Turn the ignition key and attempt to start the vehicle.
NOTE: If the vehicle does not start after 4 to 5 seconds of engine cranking, stop. Wait 3 to 4 minutes, then try again.
Repeat several times until the vehicle starts.
NOTE: Excessive engine cranking can damage vehicle starter motor. If the engine turns, but fails to start after several
attempts, other technical problem(s) might be involved. Discontinue cranking the engine until the other problem is
determined and corrected.
