PIPE AS 2W8843 - Caterpillar

Note: Certain procedures are required before an engine is started for the first time. See the Special Instruction, REHS0371, "Installation and Initial Start-Up Procedure for G3300 and G3400 Engines".Perform the required maintenance before starting the engine. This can prevent major repairs at a later date. See 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.
Inspect the drive belts for cracks and wear.
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.
Inspect the air cleaner service indicator (if equipped). Service the air cleaner filter element when the yellow diaphragm enters the red zone, or the red piston locks in the visible position.Cooling System
Inspect the cooling system for leaks or loose connections. Inspect the condition of all the hoses and 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).
For engines with separate circuit aftercooling, open the water supply.Driven Equipment
Perform any maintenance that is required 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 frayedInspect the gauge panel and the control panel for good condition. Reset any shutoff or alarm components.Fuel System
NEVER use a flame to check for gas leaks. Use a gas detector.An open flame can ignite mixtures of air and fuel. This will cause explosion and/or fire which could result in severe personal injury or death.
Check the fuel system for leaks with a gas detector.
Inspect the fuel lines for loose fittings. Ensure that the fuel lines are properly clamped.
Ensure that the fuel is supplied to the engine at the correct pressure for the engine.Lubrication System
