Engine Operating GuidelinesNormal Engine OperationObserve engine coolant temperature and engine oilpressure. Temperatures and pressures will varybetween engines and with changing operatingconditions, temperatures, and loads.Normal engine coolant operating temperature range is82°–94°C (180°–202°F). If coolant temperature risesabove 112°C (234°F), reduce load on engine. Unlesstemperature drops quickly, stop engine and determinecause before resuming operation.Operate the engine under a lighter load and at slowerthan normal speed for first 15 minutes after start-up.DO NOT run engine at slow idle.IMPORTANT: Should the engine die whileoperating under load, immediatelyremove load and restart the engine.Overheating of the turbochargerparts may occur when oil flow isstopped.Stop engine immediately if there are any signs of partfailure. Symptoms that may be early signs of engineproblems are:• Sudden drop in oil pressure• Abnormal coolant temperatures• Unusual noise or vibration• Sudden loss of power• Excessive black exhaust• Excessive fuel consumption• Excessive oil consumption• Fluid leaksRG,RG34710,5045–19–30JAN98–1/115-15 060106PN=55
