G20, 30, 40 SIIIA Operation & Maintenance Manual
PERIODICAL INSPECTION AND MAINTENANCE
INSPECTION AFTER INITIAL 50 HOURS OPERATION
(a) Replacing the engine oil and engine oil filter
(1st time)
Excercise caution when handling hot engine oil as it may
cause serious burns. After running the engine, let the oil
cool until it is just warm before draining and replacing. It
is most effective to drain the engine oil while the engine is
still warm.
In early period of use, the engine oil gets dirty rapidly
because of the initial wear of internal parts. Replace the
engine oil earlier.
Engine oil filter should also, be replaced when the engine
oil is replaced.
Engine oil and engine oil filter replacing procedures are
as follows:
Remove the oil filler cap to drain easily while draining the
engine oil.
1) Prepare a waste oil container collecting waste oil.
2) Loosen the drain plug using a wrench (customer
procured) to drain the engine oil.
3) Securely tighten the drain plug after draining the
engine oil.
4) Turn the engine oil filter counter-clockwise using a
filter wrench (customer procured) to remove It.
5) Clean the engine oil filter mounting face.
6) Moisten the new engine oil filter gasket with the
engine oil and install the new engine oil filter
manually turning it clockwise until it comes into
contact with the mounting surface, and tighten it
further to 3/4 of a turn with the filter wrench.

7) Fill with the new engine oil until it reaches the
specified level as explained in OPERATION section.
8) Warm up the engine by running for 5 minutes while
checking any oil leakage.
9) Stop the engine after warming up and leave it
stopping for about 10 minute to recheck the engine
oil level with dipstick and replenish the engine oil. If
any oil is spilled, wipe it away with a clean cloth.
10) Resume engine oil and filter changes at 250 our
intervals (with non Doosan fluids) or 500 hour
intervals with Doosan Protect engine fluid and filters.
NOTE: The use of genuine Doosan oil and filters will
qualify for extended warranty coverage. Refer
