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.
Under-the-Hood Inspection
Perform the required daily maintenance and other periodic maintenance before you start the engine. Inspect the engine compartment. This inspection can help prevent major repairs at a later date. Refer to the Operation and Maintenance Manual, "Walk-Around Inspection" topic (Maintenance Section) for more information.
For the maximum service life of the engine, make a thorough inspection before you start the engine. Look for the following items: oil leaks, coolant leaks, loose bolts and trash buildup. Remove trash buildup and arrange for repairs, as needed.
Inspect the cooling system hoses for cracks and for loose clamps.
Inspect the alternator and accessory drive belts for cracks, breaks, and other damage.
Inspect the wiring for loose connections and for worn wires or frayed wires.
Check the fuel supply. Drain water from the water separator (if equipped). Open the fuel supply valve.
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.
Do not start the engine or do not move any of the controls if there is a "DO NOT OPERATE" warning tag or similar warning tag attached to the start switch or to the controls.
Ensure that the areas around the rotating parts are clear.
All of the guards must be put in place. Check for damaged guards or for missing guards. Repair any damaged guards. Replace damaged guards and/or missing guards.
Disconnect any battery chargers that are not protected against the high current drain that is created when the electric starting motor (if equipped) is engaged. Check electrical cables and check the battery for poor connections and for corrosion.
Reset all of the shutoffs or alarm components.
Check the engine lubrication oil level. Maintain the oil level between the "ADD" mark and the "FULL" mark on the oil level gauge.
Check the coolant level. Observe the coolant level in the coolant recovery tank (if equipped). Maintain the coolant level to the "FULL" mark on the coolant recovery tank.
If the engine is not equipped with a coolant recovery tank maintain the coolant level within 13 mm (.5 inch) of the bottom of the filler pipe. If the engine is equipped with a sight glass, maintain the coolant level in the sight glass.
Observe the air cleaner service indicator (if equipped). Service the air cleaner when the yellow diaphragm enters the red zone, or when the red piston locks in the visible position.
Ensure that any driven equipment has been disengaged. Remove any electrical loads.
Inspect the exhaust system.
Ensure that the J1939 datalink has been disconnected.Cold Weather Starting
Starting the engine and operation in cold weather is dependent on the type of fuel that is used, the oil viscosity, and other optional starting aids. For more information, refer to this Operation and Maintenance Manual, "Cold Weather Operation" topic (Operation Section).Air Inlet Heater
