Batteries give off flammable fumes that can explode resulting in personal injury. Prevent sparks near the batteries. They could cause vapors to explode. Do not allow the jump start cable ends to contact each other or the machine. Do not smoke when checking battery electrolyte levels. Electrolyte is an acid and can cause personal injury if it contacts skin or eyes. Always wear eye protection when starting a machine with jump start cables. Improper jump start procedures can cause an explosion resulting in personal injury. Always connect the positive (+) to positive (+) and the negative (-) to negative (-). Jump start only with an energy source with the same voltage as the stalled machine. Turn off all lights and accessories on the stalled machine. Otherwise, they will operate when the energy source is connected.
