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
Ensure the following conditions:
The air inlet piping and the air filters are in place.
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, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations" (Maintenance Section).Engine Protective System
Perform a lamp test for the alarm system.Reset all the devices that may prevent the engine from starting:
Air shutoff
Control panel
Overspeed switchPumping air into the pneumatic linkage of the fuel rack shutoff may be necessary.Fuel System
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.
Open all fuel supply lines and fuel return lines.
Inspect the fuel lines for loose fittings and leaks. Ensure that the fuel lines are properly clamped.
Check the fuel supply. Keep fuel tanks nearly full. Partially filled tanks will collect moisture. Do not overfill the fuel tank. When fuel is warm, fuel expands and the fuel may overflow.
Drain water and sediment from the fuel tank.
Drain water and sediment from the primary filter/water separators.Lubrication 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 WITH OIL COLD" side of the oil level gauge. For information on the proper oil to use, see the 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
Ensure that the engine control system allows the engine to be started from the local position.
Ensure that the engine will be started at low idle rpm.
Ensure that the barring device is fully disengaged.
Drain moisture and sediment from the air tank and from any other air piping.
Check the air pressure for starting. Open the air supply valve.Note: If the engine is equipped with a system for external support, prepare the system before starting the engine. Ensure that all systems for engine support are enabled. Perform all prestart checks for the control system.Purge the Cylinders

Cylinder pressure valve (Kiene valve)
(1) Cap nut
(2) Valve cock
Fluids may escape from the cylinder pressure valves at high velocity during this procedure and cause personal injury. Always stay clear and keep personnel away from the cylinder pressure valves during this procedure.
Remove cap nuts (1). Turn valve cocks (2) counterclockwise for 1 1/2 turns (540 degrees).
Ensure that the "FUEL ON/OFF" switch is in the "OFF" position.
Turn the "PRELUBE/START"switch to the "PRELUBE" position. When the "PRELUBE" indicator illuminates, turn the "PRELUBE/START" switch to the "START" position to rotate the crankshaft for a few revolutions.
Inspect all the outlets of the cylinder pressure valves for indications of fluid.If fluid is found, do not continue the start-up. Inform the maintenance personnel. Record the cylinder number, the engine serial number, and the service hours.If no signs of fluid discharge are found, ensure that all the cylinder pressure valves and the cap nuts are clean. Tighten valve cocks (2) to 24 3 N m (18 2 lb ft). Install cap nuts (2) and tighten to 17 3 N m (13 2 lb ft).
Ensure that the driven equipment is disengaged.Note: Two typical control panels are illustrated. If the engine is equipped with a different control panel, follow the instructions that are provided by the OEM of the control panel.
