Prestart Checks
Walk-Around Inspection
Perform required Daily and other periodic maintenance before starting the engine. Make a walk-around inspection of the installation. It only takes a few minutes to make minor corrections. This can prevent major repairs at a later date.* For maximum service life of your engine, make a thorough inspection before starting the engine. Look for items such as oil or coolant leaks, loose bolts, and trash build-up. Remove trash build-up and have repairs made as needed.* Inspect the radiator hoses for cracks and loose clamps.* Inspect the fan belts and accessory drive belts for cracks, breaks, and other damage.* Inspect the wiring for loose connections and for worn or frayed wires.* Check the fuel supply. Drain water from the water separator (if equipped). Open the fuel supply valve.
All valves in fuel return line must be open before and during engine operation to prevent high fuel pressure. High fuel pressure may cause filter housing failure or other damage.
If the engine has not been run for several weeks, fuel may have drained and allowed air into the filter housing. Also, when fuel filters have been changed, some air space will be left in the housing. In these instances, prime the fuel system. Refer to Priming the Fuel System in this publication for more information.
Diesel 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.
* Do not start the engine or move any of the controls if there is a DO NOT OPERATE or similar warning tag attached to the start switch or controls.* The operator must be satisfied that no one will be endangered before starting the engine.* Disconnect the battery charger (if equipped).* Reset any shutoff or alarm components (if equipped): Low Oil Pressure, Overspeed, Air Shutoff.* Check for damaged or missing guards. Repair or replace any damaged or missing guards.
Oil Level Gauge (Dipstick):(1) ENGINE STOPPED sideLOW IDLE side (2) ADD mark, and FULL mark.* Check the oil level. The ENGINE STOPPED side of the dipstick is marked to read when the engine is stopped. The LOW IDLE side of the dipstick is marked to read when the engine is at low idle. Maintain the oil level between the ADD and FULL marks.* Check the coolant level. Make sure the engine is cool. Remove the radiator or expansion tank filler cap slowly to relieve any pressure. Maintain the coolant to within 13mm (1/2 inch) of the bottom of the fill pipe.* Observe the air cleaner service indicator (if equipped). Service the air cleaner when the yellow diaphragm enters the red zone, or the red piston locks in the visible position.Electric Starting
Startability will be improved at temperatures below 12°C (55°F) by the use of a starting aid. A jacket water (coolant) heater or other means can be used to heat the crankcase oil.
Do not crank the engine for more than 30 seconds. Allow the
