Illustration 1 g00704000Use of personal protection equipment (PPE) may be needed.All fuels, most lubricants, and some coolant mixtures are flammable.Always perform a Walk-Around Inspection, which may help you identify a fire hazard. Do not operate a product when a fire hazard exists. Contact your Caterpillar dealer for service.Flammable fluids that are leaking or spilled onto hot surfaces or onto electrical components can cause a fire. Fire may cause personal injury and property damage. A flash fire may result if the covers for the engine crankcase are removed within 15 minutes after an emergency shutdown.Determine whether the engine will be operated in an environment that allows combustible gases to be drawn into the air inlet system. These gases could cause the engine to overspeed. Personal injury, property damage, or engine damage could result.If the application involves the presence of combustible gases, consult your Caterpillar dealer for additional information about suitable protection devices.Remove all flammable materials such as fuel, oil, and debris from the engine. Do not allow any flammable materials to accumulate on the engine.All fluids that are captured in the fluid spill containment basin should be cleaned up immediately. Failure to clean up spilled fluids can cause a fire. Fire may cause personal injury and property damage.Store fuels and lubricants in properly marked containers away from unauthorized persons. Store oily rags and any flammable materials in protective containers. Do not smoke in areas that are used for storing flammable materials.Do not expose the engine to any flame.Exhaust shields (if equipped) protect hot exhaust components from oil or fuel spray from a failed line, tube, or seal. Exhaust shields must be installed correctly.Do not weld on lines or tanks that contain flammable fluids. Do not flame cut lines or tanks that contain flammable fluid. Clean any such lines or tanks thoroughly with a nonflammable solvent prior to welding or flame cutting.Wiring must be kept in good condition. Properly route and securely attach all electrical wires. Check all electrical wires daily. Repair any wires that are loose or frayed before you operate the engine. Clean all electrical connections and tighten all electrical connections.Eliminate all wiring that is unattached or unnecessary. Do not use any wires or cables that are smaller than the recommended gauge. Do not bypass any fuses and/or circuit breakers.Arcing or sparking could cause a fire. Secure connections, recommended wiring, and properly maintained battery cables will help to prevent arcing or sparking.Inspect all lines and hoses for wear or for deterioration. Properly route all hoses. The lines and hoses must have adequate support and secure clamps. Tighten all connections to the recommended torque. Leaks can cause fires.Properly install all oil filters and all fuel filters. The filter housings must be tightened to the proper torque.
Illustration 2 g00704059Use caution when you are refueling an engine. Do not smoke while you are refueling an engine. Do not refuel an engine near open flames or sparks. Always stop the engine before refueling.Note: Avoid static electricity risk when fueling. Ultra-low sulfur diesel fuel (ULSD fuel) poses a greater static ignition hazard than earlier diesel formulations with a higher sulfur content. Avoid death or serious injury from fire or explosion. Consult your fuel or fuel system supplier to ensure that the delivery system is in compliance with fueling standards for proper grounding and bonding practices.
Illustration 3 g02298225Gases from a battery can explode. Keep any open flames or sparks away from the top of a battery. Do not smoke in battery charging areas.Never check the battery charge by placing a metal object across the terminal posts. Use a voltmeter or a hydrometer.Improper jumper cable connections can cause an explosion that can result in injury. Refer to the Operation Section of this manual for specific instructions.Do not charge a frozen battery. Charging a frozen battery may cause an explosion.The batteries must be kept clean. The covers (if equipped) must be kept on the cells. Use the recommended cables, connections, and battery box covers when the engine is operated.Fire Extinguisher
Make sure that a fire extinguisher is available. Be familiar with the operation of the fire extinguisher. Inspect the fire extinguisher and service the fire extinguisher regularly. Obey the recommendations on the instruction plate.Ether
Do not use ether as a starting aid. Refer to this Operation and Maintenance Manual, "Starting the Engine" for information about starting the engine.Lines, Tubes, and Hoses
Do not bend high-pressure lines. Do not strike high-pressure lines. Do not install any lines that are bent or damaged.Repair any lines that are loose or damaged. Leaks can cause fires. Consult your Caterpillar dealer for repair or for replacement parts.Check lines, tubes, and hoses carefully. Do not use your bare hand to check for leaks. Use a board or cardboard to check for leaks. Tighten all connections to the recommended torque.Replace the parts if any of the following conditions are present:
End fittings are damaged or leaking.
Outer coverings are chafed or cut.
Wires are exposed.
Outer coverings are ballooning.
Portions of the hoses are kinked.
Outer covers have embedded armoring.
End fittings are displaced.Make sure that all clamps, guards, and heat shields are installed correctly in order to prevent vibration, rubbing against other parts, and excessive heat.
