Personal Precautions

WARNING! RISK OF EXPLOSIVE GASES. A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

  • NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.
  • Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring to metal, causing a severe burn.
  • Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short-circuit the battery or other electrical parts, which may cause an explosion.
  • Do not permit the internal battery of the unit to freeze. Never charge a frozen battery.
  • To prevent sparking, NEVER allow clamps to touch together or contact the same piece of metal.
  • Consider having someone nearby to come to your aid when you work near a lead-acid battery.
  • Have plenty of fresh water, soap, and baking soda nearby for use, in case battery acid contacts your eyes, skin, or clothing.
  • Wear complete eye and body protection, including safety goggles and protective clothing. Avoid touching your eyes while working near the battery.
  • If battery acid contacts your skin or clothing, immediately wash the area with soap and water. If acid enters your eye, immediately flood the eye with cold running water for at least 10 minutes and get medical attention right away.
  • Neutralize any acid spills thoroughly with baking soda before attempting to clean up.

WARNING! RISK OF CONTACT WITH BATTERY ACID. BATTERY ACID IS A HIGHLY CORROSIVE SULFURIC ACID.

  • Make sure the area around the battery is well ventilated while the unit is in use.
  • Clean the battery terminals before using the jump starter. During cleaning, keep airborne corrosion from coming into contact with your eyes, nose, and mouth. Use baking soda and water to neutralize the battery acid and help eliminate airborne corrosion. Do not touch your eyes, nose, or mouth.
  • Determine the voltage of the battery by referring to the vehicle owner’s manual, and make sure that the output voltage is 12V.
  • Make sure that the unit’s cable clamps make tight connections.

WARNING! A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

  • Plug the clamps into the unit, and then attach the output cables to the battery and chassis as indicated below. Never allow the output clamps to touch each other.
  • Position the DC cables to reduce the risk of damage from the hood, door, and moving or hot engine parts. NOTE: If it is necessary to close the hood during the jump-starting process, ensure that the hood does not touch the metal part of the battery clips or cut the insulation of the cables.
  • 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.
  • 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.

OPERATING INSTRUCTIONS

JUMP STARTING A VEHICLE ENGINE

NOTE: Use only the model number SA934 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 of 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. The green LED on the smart cable should light up. 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. NOTE: If the car does not crank a second time, check the smart cable to see if the green LED is lit. If you hear beeping or an LED is flashing, refer to section 10, Troubleshooting. When the condition is corrected, the smart cable will automatically reset. Cold weather may affect the performance of the jump starter’s lithium battery. If you hear only a click and the engine does not turn over, try the following: With the jump starter connected to the car battery and the green LED illuminated on the smart cable, turn on all lights and electrical accessories for one minute. This draws current from the jump starter and warms the battery. Now, try to crank the engine. If it does not turn over, repeat the procedure. Extremely cold weather may require two or three battery warmings before the engine will start. If no activity is detected, the smart cable will automatically shut off after 90 seconds, and the red and green LEDs will be solid. To reset, disconnect the clamps from the vehicle battery, and then reconnect. IMPORTANT: DO NOT attempt to jump-start your vehicle more than three consecutive times. If the vehicle will not start after three attempts, consult a service technician.
