Information:
Oils
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin.Keep all exhaust manifold and turbocharger shields in place to protect hot exhaust from oil spray in the event of a line, tube or seal failure.Always wear protective glasses when working with 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.Fire or Explosion Prevention
A flash fire can result in personal injury if crankcase covers are removed within fifteen minutes after an emergency shutdown.Fire may result from lubricating oil or fuel sprayed on hot surfaces causing personal injury and property damage. Inspect all lines and tubes for wear or deterioration. They must be routed, supported or clamped securely. Tighten all connections to the recommended torque.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.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. Diesel fuel is flammable. Gasoline is flammable. The mixture of diesel and gasoline fumes are extremely explosive. Keep all fuels and lubricants stored in properly marked containers and away from all unauthorized persons.Provide adequate and safe disposal of waste oil and petroleum products. Follow all federal, state and local laws and regulations regarding waste oil and hazardous waste.Oil and fuel filters must be properly installed and tightened when being changed.Remove all flammable materials such as fuel, oil and other debris before they accumulate on the engine.Collect drained liquids and wipe up all oil, fuel or coolant spills. Remember; all fuels, most lubricants and some coolant mixtures are flammable as well as creating a hazard to walking if spilled.DO NOT SMOKE while refueling or in a refueling area. DO NOT SMOKE in areas where batteries are charged, or where flammable materials are stored. 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.Clean and tighten all electrical connections. Check regularly for loose or frayed electrical wires. Refer to maintenance schedules for interval. Have all loose or frayed electrical wires tightened, repaired or replaced before operating the engine.Wiring must be kept in good condition, properly routed and firmly attached. Routinely inspect wiring for wear or deterioration. Loose, unattached, or unnecessary wiring must be eliminated. All wires and cables must be of
