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. |
 |
Perform the required daily maintenance and other periodic maintenance before starting the engine. Inspect the engine room. This inspection can help prevent major repairs at a later date. See this Operation and Maintenance Manual (Maintenance Section), "Maintenance Interval Schedule".
Walk-Around Inspection
| NOTICE |
|---|
For any type of leak (coolant, lube, or fuel) clean up the fluid. If leaking is observed, find the source and correct the leak. If leaking is suspected, check the fluid levels more often than recommended until the leak is found or fixed, or until the suspicion of a leak is proved to be unwarranted. |
To obtain maximum service life for your engine, make a thorough inspection before starting the engine. Make a walk-around inspection of the installation. Look for items such as oil or coolant leaks, loose bolts, and trash buildup. Remove any trash. Arrange for repairs, as needed.
- The guards must be in the proper place. Repair damaged guards or replace missing guards.
- Ensure that the areas around the rotating parts are clear.
Aftertreatment System
CEM
- Ensure area around CEM is clear of flammable materials.
- Inspect access panels.
- Inspect injector.
- Inspect bulkhead fittings.
- Ensure that urea and air lines are connected.
- Inspect sensors.
- Inspect wiring harness.
- Check the A/C power.
Dosing Cabinet
- Ensure that filter screens are in place.
- Ensure that drains are closed.
- Ensure that all lines are connected.
- Check for leaking fluids. Ensure all fluids that have leaked are cleaned up and properly disposed of.
Air Inlet System
- Ensure that the air inlet piping and the air filters are in place.
- Ensure that all clamps and connections are secure.
- Observe the air cleaner service indicator. Service the air cleaner when the yellow diaphragm enters the red zone, or when the red piston locks in the visible position.
Cooling System
- Inspect the cooling system for leaks or loose connections.
- Inspect the cooling system hoses for cracks and for loose clamps.
- Inspect the water pumps for evidence of leaks.
- Inspect the fan drive belts for cracks and for deterioration.
- Check the coolant level. Add coolant, if necessary. For information on the proper coolant to use, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations".
Driven Equipment
- Perform any maintenance that is required for the driven equipment. Refer to the Operation and Maintenance Manual for the generator.
- Ensure that the main circuit breaker is open.
Electrical System
Inspect the wiring for the following conditions:
- Loose connections
- Wiring that is worn or frayed
Inspect the alternator belt for cracks and for deterioration.
Ensure that the grounds are secure.
Fuel System
| NOTICE |
|---|
All valves in the fuel return line must be open before and during engine operation to help prevent high fuel pressure. High fuel pressure may cause filter housing failure or other damage. |
- Inspect the fuel lines for loose fittings and leaks. Ensure that the fuel lines are properly clamped.
- Ensure that the fuel is supplied to the engine.
If the engine has not been started for several weeks, fuel may have drained from the fuel system. Air may have entered the filter housing. Also, when fuel filters have been changed, some air space will be left in the housing. In these instances, prime the fuel system. See this Operation and Maintenance Manual (Maintenance Section), "Fuel System-Prime" for information on priming the fuel system.

Oil level gauge (1) "ADD" mark (2) "FULL" mark | |
- Check the engine crankcase oil level. Maintain the oil level between the "ADD" and "FULL " marks on the "ENGINE STOPPED" side of the oil level gauge. For information on the proper oil to use, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations".
- Check for leaks at the following components: crankshaft seals, crankcase, oil filters, oil gallery plugs, sensors and valve covers.
- Inspect the tubes, tee pieces, and clamps on the crankcase breathers.
- Inspect the Closed Crankcase Ventilation (CCV) filter, if equipped.
Starting System
- Disconnect any battery chargers that are not protected against the high current drain that is created when the electric starting motor is engaged.
- Inspect the battery cables for good connections and for corrosion.
- Inspect the gauges and the control panel for good condition.
- Reset the shutoff and alarm components.
