Coolant
To prevent personal injury, do not step up on engine to remove the filler cap, if applicable. Use an adequate ladder.At operating temperature, the engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot water. When pressure is relieved rapidly, this hot water can turn into steam.Allow cooling system components to cool before draining.Any contact with hot water or steam can cause severe burns.Check the coolant level only after the engine has been stopped and the filler cap is cool enough to remove with your bare hand.Remove the cooling system filler cap slowly to relieve pressure.Cooling system supplemental additive contains alkali. To prevent personal injury, avoid contact with the skin and eyes and do not drink.Oils
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin.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.Batteries give off flammable fumes which can explode.Always thaw a frozen battery before jump starting. Frozen batteries can explode.Do not smoke when observing the battery electrolyte levels.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.Inhaling freon gas through a lit cigarette or other smoking method, or inhaling fumes released from a flame contacting freon could cause bodily harm or death. Do not smoke when servicing, charging or working around air conditioners or where freon gas may be present.All fuels, most lubricants and some coolant mixtures are flammable.Diesel fuel is flammable. Gasoline is flammable. The mixture of diesel and gasoline fumes are extremely explosive.Do not smoke while refueling or in a refueling area.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 truck engine.Do not expose the engine to flames, burning brush, etc., if at all possible.Exhaust shields (if equipped), 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
