Batteries
Batteries give off flammable fumes which can explode. Do not smoke when servicing the batteries.Battery electrolyte contains acid and can cause injury. Avoid contact with the skin and eyes.Wash hands after touching batteries and connectors. Use of gloves is recommended.Always thaw a frozen battery before jump starting. Frozen batteries can explode.Always wear protective glasses when working with batteries.Fire or Explosion Prevention
Determine whether the engine will be operated in an environment in which combustible gases could be drawn through the air inlet system. These gases could cause the engine to overspeed, which in turn could seriously damage the engine and result in bodily injury or property damage.If your application involves the presence of combustible gases, consult your Caterpillar dealer to obtain additional information concerning protection devices suitable for the application involved.All fuels, most lubricants and some coolant mixtures are flammable.Always thaw a frozen battery before jump starting. Frozen batteries can explode.Do not smoke in areas where batteries are charged, or where flammable materials are stored.Batteries give off flammable fumes which can explode.Keep all fuels and lubricants stored in properly marked containers and away from all unauthorized persons.Store all oily rags or other flammable material in a protective container, in a safe place.Do not weld or flame cut on pipes or tubes that contain flammable fluids. Clean them thoroughly with nonflammable solvent before welding or flame cutting on them.Remove all flammable materials such as fuel, oil and other debris before they accumulate on the engine.Shields, which protect hot exhaust components from oil or fuel spray in the event of a line, tube or seal failure, must be installed correctly.Never disconnect any charging unit circuit or battery circuit cable from the battery when the charging unit is operating. A spark can cause the flammable vapor mixture of hydrogen and oxygen to explode.When starting from an external source, always connect the positive (+) jumper cable to the POSITIVE (+) terminal of the battery of the engine to be started.To prevent potential sparks from igniting combustible gases produced by some batteries, attach the negative (-) boost ground cable last, to the starter NEGATIVE (-) terminal (if equipped) or to the engine block.See the Operation Section of this manual for specific starting instructions.Clean and tighten all electrical connections.
