TUBE AS 2542509 - Caterpillar

Coolant
At operating temperature, the engine coolant is hot and under pressure. The radiator and all lines to the engine contain hot water or steam. Any contact can cause severe burns.Steam can cause personal injury.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 additive contains alkali that can cause personal injury. Avoid contact with the skin and eyes and do not drink.Allow cooling system components to cool before draining.Oils
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin.At operating temperature, the hydraulic tank is hot and can be under pressure.Remove the hydraulic tank filler cap only after the engine has been stopped and the filler cap is cool enough to remove with your bare hand.Remove the hydraulic tank filler cap slowly to relieve pressure.Relieve all pressure in air, oil, fuel or cooling systems before any lines, fittings or related items are disconnected or removed.The pins and bushings in a dry track pin joint can become very hot. It is possible to burn the fingers if there is more than brief contact with these components.Batteries
Batteries give off flammable fumes which can explode.Do not smoke when observing the battery electrolyte levels.Electrolyte is an acid and can cause personal injury if it contacts skin or eyes.Always wear protective glasses when working with batteries.Fire or Explosion Prevention
All fuels, most lubricants and some coolant mixtures are flammable.Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire.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.Batteries in series may be located in separate compartments. When using jumper cables always connect positive (+) cable to positive (+) terminal of battery connected to starter solenoid and negative (-) cable from external source to starter negative (-) terminal. (If not equipped with starter negative terminal, connect to engine block.)See the "Operation Section" of this manual for specific starting instructions.Clean and tighten all electrical connections. Check daily for loose or frayed electrical wires. Have all loose or frayed electrical wires tightened, repaired or replaced before operating the machine.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 machine.Do not expose the machine to flames, burning brush, etc., if at all possible.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.Have a fire extinguisher available and know how to use it.
