  1. Turn ignition off before making cable connections.
  2. Clamp the positive (red +) clamp to the positive terminal on the vehicle battery
      (for negative ground system), or an alternate vehicle starting point as
    recommended by vehicle manufacturer.
  3. Clamp the negative (black –) clamp to the vehicle ground (non-moving metal part,
    such as the vehicle frame). 
  4. Make sure the cables are not in the path of moving engine parts (belts, fans, etc.).

  6. When the vehicle is started, disconnect the negative (–) battery clamp from the
    vehicle frame and return it to its holster.
