5.7.3 Replacement of engine oil
Generally, the oil and oil lter are required to be replaced at the same time. The oil
shall be replaced at the time when engine is stopped after operating for a period of
time and oil temperature of engine is a little lower than the operating temperature.
When replacing the oil, loosen and remove the drain plug provided on the side of
the oil sump.
After the engine oil is drained off completely, carefully inspect
the magnetic part of the drain plug for accumulation of metal
particles. Accumulation of various metal particles is the indication
of abnormal wear of internal components. Carry out the inspection
before proceeding to the next step.
Wipe, clean the drain plug and re tighten it to oil sump. Add fresh oil from oil lling
port as per required quantity of the specied grade. Start the engine and run it for
a short time. Check the oil level, top up if required.
Precautions
• Never run an engine without oil.
• Do not run an engine with oil ller port open or oil dipstick taken out.
