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 installation. This inspection can help prevent major repairs at a later date. See this Operation and Maintenance Manual , "Maintenance Interval Schedule"(Maintenance Section).
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 position. Repair damaged guards or replace missing guards.
- Ensure that the areas around the rotating parts are clear.
Air Inlet System
- 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.
- Ensure that the air inlet piping and the air filters are in place.
- Ensure that all clamps and connections are secure.
- Ensure that both of the air shutoffs are in the OPEN 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 hydraulic fan drive for leaks.
- 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" (Maintenance Section).
Driven Equipment
Note: If the engine is equipped with a system for external support, prepare the system before starting the engine. Perform all prestart checks for the control system.
- If necessary, check the oil levels of the driven equipment. Perform any maintenance that is required for the driven equipment. Refer to the literature that is provided by the OEM of the driven equipment.
- Ensure that the driven equipment is unloaded. Place the transmission in neutral.
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 will remain in the housing. In these instances, prime the fuel system. See this Operation and Maintenance Manual, "Fuel System-Prime" (Maintenance Section).
Lubrication System

Oil level gauge (1) "ADD" mark (2) "FULL" mark | |
| NOTICE |
|---|
Excessive engine oil will increase oil consumption and result in excessive deposits in the combustion chamber. Do not overfill the engine with oil. |
- Check the engine crankcase oil level. Maintain the oil level between the "ADD" and "FULL " marks on the "ENGINE STOPPED WITH OIL COLD" side of the oil level gauge. For information on the proper oil to use, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations" (Maintenance Section).
- 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.
Starting System
- Inspect the instrument panel and the control panel for good condition.
- Reset the shutoff and alarm components.
Air Starting Motor
- Inspect the air starting motor for leaks.
- Inspect the air lines for loose connections.
- Inspect the air lines for leaks.
- Check the air pressure that is supplied to the air system. There should be approximately 827 kPa (120 psi) of air pressure that is continuously supplied to the air system.
