4.11 Engine Oil Sump Level Check and Oil Replacement

（1） Remove the oil dipstick (A) on the left front of
the oil pan and check if the oil level is between the upper
scale mark and lower scale mark. If the oil level doesn't
reach the lower scale mark, add oil to the recommended
level.
（2） Before maintenance and replacement of the oil,
preheat the engine. When the engine oil temperature
reaches 50℃～60℃, unscrew the drain plug (A) below
the oil pan, discharge all of the dirty oil, and refill with
new oil.
IMPORTANT NOTE: Never mix new and old engine oil or blend different brands of oil, as this can damage
the engine. Replace the engine oil strictly in accordance with time limits recommended in the Operation
Instruction of the Diesel Engine.
