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.1. 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 ±103 kPa(3.45 bar ± 1.03 bar) (50 ±15 psi) at rated full loadspeed (1800–2500 rpm) with oil at normal operatingtemperature of 105°C (221°F).North American Instrument PanelRG11533 –UN–01DEC002. 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 GaugeAEZ Instrument Panel (Except North America)RG11593 –UN–08DEC00VDO Instrument Panel (Except North America)RG10613 –UN–21OCT99RG,RG34710,5051–19–30JAN98–1/115-17 060106PN=57
