General Hazard Information
Attach a DO NOT OPERATE or similar warning tag to start switch or controls before performing maintenance or repairing the engine. These tags, SEHS7332, are available from your Caterpillar dealer. When appropriate, attach tags at the engine and at each start position and disconnect starting controls.Do not allow unauthorized personnel on or around the engine when it is being serviced.Diesel engine exhaust contains products of combustion which may be harmful to your health. Always start and operate the engine in a well ventilated area and, if in an enclosed area, vent the exhaust to the outside.Use caution when removing cover plates. Gradually loosen (do not remove) the last two bolts or nuts located at opposite ends of the cover or device. Pry cover loose to relieve any spring or other pressure, before removing the last bolts or nuts.Use caution when removing vent release valve, grease fittings, pressure taps, breathers or drain plugs. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids under pressure.* Wear a hard hat, protective glasses, hearing protection 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.* Use all cleaning solutions with care.* Never put maintenance fluids into glass containers since glass containers can break.* Report all needed repairs.UNLESS INSTRUCTED DIFFERENTLY, PERFORM ALL MAINTENANCE AS FOLLOWS:* Stop the engine.* Do not attempt any repairs or adjustments to the engine or driven equipment while it is running.* Do not attempt repairs you do not understand.* Ensure the protective locks or controls are in the applied position.* Be sure the remote starting system is inoperative on the equipment being serviced. Always disconnect the engine starter circuit when working on the generator. Place the automatic start-stop switch to the STOP position before working on the equipment to prevent accidental starting. * Disconnect the batteries whenever performing any maintenance or before servicing the electrical system. If the engine has electric starters, disconnect and tape the battery ground leads to prevent accidental starting.* Do not attempt repairs you do not understand. Use proper tools; replace or repair broken or damaged equipment.* When starting an engine after repairs have been made to the fuel system or governor, make provisions for shutting off the engine's intake air and/or fuel supply (to stop the engine), in case there is an overspeed on start-up.Pressure Air and Water
Pressure air can cause personal injury. When using pressure air for cleaning, wear a protective face shield, protective clothing and protective shoes.The maximum air pressure must be below 200 kPa (30 psi) for cleaning purposes.Wear eye protection at all times when cleaning the cooling system. Pressurized water could cause debris and/or hot water to be blown and result in personal injury.Fluid Penetration
Always use a board or cardboard when checking for a leak. Escaping fluid under pressure, even a pin-hole size leak, can penetrate body tissue, causing serious injury or possible death.If fluid is injected into your skin, it must be treated by a doctor familiar with this type of injury immediately.Asbestos Information
Your Caterpillar engine and replacement parts shipped from the factory are asbestos free. Caterpillar recommends the use of ONLY genuine Caterpillar parts.Lines, Tubes and Hoses
Do not bend or strike high pressure lines. Do not install bent or damaged lines, tubes or hoses.Repair any loose or damaged fuel and oil lines, tubes and hoses. Leaks can cause fires.Inspect all lines, tubes and hoses carefully. Do not use your bare hands to check for leaks. Tighten all connections to the recommended torque. Check for the following:* End fittings damaged, leaking or displaced.* Outer covering chafed or cut and wire reinforcing exposed.* Outer covering ballooning locally.* Evidence of kinking or crushing of the flexible part of the hose.* Armoring embedded in the outer cover.Burn Prevention
Do not touch any part of an operating engine. Allow the engine to cool before any repair or maintenance is performed on the engine.Make sure that all clamps, guards and heat shields are installed correctly to prevent vibration, rubbing against other parts and excessive heat during operation.Relieve all pressure in air, oil, fuel or cooling systems before any lines, fittings or related items are disconnected or removed.Coolant
At operating temperature, the engine coolant is hot and under pressure. The cooling system and all lines to heaters or the engine contain hot liquid. When pressure is relieved rapidly, this hot liquid can turn into steam.Allow cooling system components to cool before draining. Any contact with hot liquid or steam can cause severe burns. Check the coolant level only after the engine has been stopped and the vent release valve is cool enough to remove with your bare hand.Remove the cooling system vent release valve slowly to relieve pressure. Use caution when removing vent release valve, grease fittings, pressure taps, breathers or drain plugs. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids under pressure.Cooling system additive (conditioner) 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.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.Batteries
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.Do not smoke when observing the battery electrolyte levels. Batteries give off flammable fumes which can explode. Ensure there is proper ventilation for batteries which are located in an enclosure.Never disconnect any charging unit circuit or battery circuit cable from the battery when charging unit is operating. A spark can cause the flammable vapor mixture of hydrogen
