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 area in the vicinity of the diesel engine. This inspection can help prevent major repairs at a later date. See this Operation and Maintenance Manual (Maintenance Section), "Maintenance Interval Schedule".

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.
- Ensure that the air inlet piping and the air filters are in place.
- Ensure that all clamps and connections are secure.
- Ensure that the air shutoff valves are open.
- Check the display of the Blackstart System in order to ensure that the Blackstart System is functional.
- Ensure that the engine control switch is in the correct position.
- 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.
- Check the coolant level. Add coolant, if necessary. For information on the proper coolant to use, see this Operation and Maintenance Manual (Maintenance Section), "Cooling System Specifications".
- 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.
Inspect the wiring for the following conditions:
- Loose connections
- Wiring that is worn or frayed
Ensure that the grounds are secure.

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 (Maintenance Section), "Lubricant Specifications".
- 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 gauges and the control panel for good condition.
- Reset the shutoff and alarm components.
- Drain moisture and sediment from the air tank and from any other air piping.
- Check the oil level in the lubricator for the air starting motor. Keep the lubricator at least half full. Add oil, if necessary.
- Verify that the slow roll motor is not engaged.
- Check the air pressure for starting. Open the air supply valve.
