It is important to idle the engine 3 to 5 minutes before shutting it down to allow the lubricating oil and water to carry heat away from the combustion chamber, bearings, shafts etc.
Long Periods of idling are not good for an engine because the combustion chamber temperatures drops to low and fuel will not burn completely. This will cause carbon to clog injector spray holes and piston rings and can result in stuck valves.
To prevent permanent cranking motor damage, do not crank the engine for more than 10sec continuously.
If engine does not start after about three repeated attempts, then starter should not be operated and the fuel system has to be checked for any faults.
Engine Oil Pressure must be indicated on the gauge within 15s after starting. If oil pressure is not indicated shut off the engine immediately.
The Oil Temperature must be between 75 to 105 degree Celsius. If any sudden increase in oil temp, shut off the engine.
Coolant temp must be maintained between 75 to 95 degree Celsius.
Normal Engine pressure at 105degree Celsius should be between 3 to 7 kg/cm2 at rated speed and 1 to 2 kg/cm2 at idle.
