Perform the required daily maintenance and other periodic maintenance before starting the engine. This process can prevent major repairs at a later date. Refer to this Operation and Maintenance Manual, "Maintenance Interval Schedule" (Maintenance Section).Walk-Around Inspection
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. Make repairs, if necessary.
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.Air Inlet System
Unburned gas in the air inlet and exhaust system may ignite when the engine is started. Personal injury and/or property damage may result.Before starting an engine that may contain unburned gas, purge the unburned gas from the air inlet and exhaust system. Refer to the topic on purging unburned gas in the "Starting the Engine" section.
Ensure that the air inlet piping and the air filters are in place.
Ensure that all clamps and connections are secure.Cooling System
Inspect the cooling system for leaks or loose connections. Inspect the condition of all the pipes for the cooling system. Ensure that the connections are properly clamped.
Inspect the water pumps for evidence of leaks.
Check the coolant level. Add coolant, if necessary. For information on the proper coolant to use, refer to this Operation and Maintenance Manual, "Refill Capacities and Recommendations" (Maintenance Section).Driven Equipment
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.
If the engine is equipped with a clutch, ensure that the clutch is disengaged.
For generator set engines, ensure that the main circuit breaker is open.Electrical System

Check the engine oil level. Add engine oil if the level is in the "ADD" zone. If the engine is running, maintain the level in the "RUNNING FULL" zone. For information on the proper engine oil to use, refer to this Operation and Maintenance Manual, "Refill Capacities and Recommendations" (Maintenance Section).
Check for leaks at the following components: crankshaft seals, crankcase, engine oil filters, plugs for the engine oil gallery, sensors and valve covers.
Inspect the tubes, tee pieces, and clamps on the crankcase breathers.
If the engine has an air cleaner for crankcase ventilation, inspect the air cleaner service indicator.
