Engine Operating GuidelinesWarming EngineIMPORTANT: To assure proper lubrication, operateengine at or below 1200 rpm with noload for 1–2 minutes. Extend this period2–4 minutes when operating attemperatures below freezing.Engines used in generator setapplications where the governor islocked at a specified speed may nothave a slow idle function. Operate theseengines at high idle for 1 to 2 minutesbefore applying the load. Thisprocedure does not apply to standbygenerator sets where the engine isloaded immediately upon reaching ratedspeed.Standard North American Instrument PanelRG11612 –UN–17OCT011. Check oil pressure gauge (A) as soon as engine starts.If gauge needle does not rise above minimum oilpressure specification of 105 kPa (1.05 bar) (15.0 psi)within 5 seconds, stop the engine and determine thecause. Normal engine oil pressure is 345 kPa (3.45bar) (50 psi) at rated full load speed (1800–2500 rpm)with oil at normal operating temperature of 115°C(240°F).Standard VDO Instrument Panel (Except North America)RG10613 –UN–21OCT99NOTE: On certain engines, the oil pressure and coolanttemperature gauges are replaced by indicatorwarning lights. The lights must be "OFF" whenengine is running.2. Watch coolant temperature gauge (B). Do not placeengine under full load until it is properly warmed up.The normal engine coolant temperature range is 82°—94°C (180°—202°F).NOTE: It is a good practice to operate the engine under alighter load and at lower speeds than normal forthe first few minutes after start-up.A—Oil Pressure GaugeB—Coolant Temperature GaugeRG,RG34710,5560–19–08JAN02–1/115-12 110306PN=56
