These tags, Form SEHS7332, are available from your Caterpillar dealer.Perform all maintenance unless otherwise specified as follows: The engine stopped.The protective locks or controls in the applied position.Wear a hard hat, protective glasses and other protective equipment as required by job conditions.Do not wear loose clothing or jewelry that can catch on controls or other parts of the engine.Make certain all protective guards and covers are secured in place.Disconnect the batteries before servicing the electrical system.Do not allow unauthorized personnel in the operator's compartment when it is being serviced.Use the proper tools. Replace or repair broken or damaged equipment.Do not attempt repairs you do not understand.Operate the engine only in a well ventilated area.When operating the engine in a closed area, vent the exhaust to the outside.Remove all tools, electrical cords and other loose items from the engine before starting.When starting an engine after repair, make provisions for shutting off air supply, to stop the engine, in case there is an overspeed on start-up.Pressure air can cause personal injury. When using pressure air for cleaning, wear a protective face shield and protective clothing.Never put maintenance fluids into glass containers.Crushing or Cutting Prevention
Never attempt adjustments while the engine is running unless otherwise specified.Stay clear of all rotating and moving parts.Keep objects away from moving fan blades. They will throw or cut any object or tool that falls or is pushed into them.Wear protective glasses when striking a retainer pin to avoid injury to your eyes.Chips or other debris can fly off objects when struck. Make sure no one can be injured by flying debris before striking any object.Burn Prevention
At operating temperature, the engine coolant is hot and under pressure. The expansion tank and all lines to heaters or the engine contain hot water or steam. Any contact 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 conditioner contains alkali. To prevent personal injury, avoid contact with the skin and eyes and do not drink.Allow cooling system components to cool before draining.Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin.Relieve all pressure in air, oil, fuel or cooling systems before any lines, fittings or related items are disconnected or removed.Battery electrolyte contains acid and can cause injury. Avoid contact with skin or eyes.Fire or Explosion Prevention
All fuels, most lubricants and some coolant mixtures are flammable.Accumulated grease and oil on the engine is a fire hazard.Remove the grease, oil and debris at least every 1000 hours and each time any significant quantity of oil is spilled on the engine.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.When starting from an external source, always connect the positive (+) boost cable to the positive (+) terminal of the battery of the engine to be started.Attach the negative (-) boost ground cable last, away from the battery. See the Operation and Maintenance Guide for specific 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.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.Do not bend or strike high pressure lines. Do not install bent or damaged lines, tubes or hoses.Inspect all lines, tubes, and hoses carefully. Do not use your bare hand to check for leaks. Tighten all connections to the recommended torque.Repair any loose or damaged fuel and oil lines, tubes and hoses. Leaks can cause fires.Debris, dirt and foreign material must not be allowed to accumulate around, on the engine or in the engine compartment as overheating or fire could result.Make sure that all clamps, guards and heat shields are installed correctly to prevent vibration, rubbing against other parts and excessive heat during operation.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.Ether is flammable. Do not smoke while changing ether cylinders.Use ether only in well ventilated areas.Keep ether cylinders out of the reach of unauthorized persons.Do not store ether cylinders in direct sunlight. Discard cylinders in a safe place. Do not puncture or burn cylinders.Fire Extinguisher
Always have a fire extinguisher available and know how to use it. Inspect and have it serviced as recommended on its instruction plate.
