PERIODICAL INSPECTION AND
MAINTENANCE
LUBRICATING SYSTEM
Servicing of the engine oil and oil filter element will affect the engine
performance as well as the engine life. Change the engine oil and the
oil filter in accordance with the recommended service intervals.
Engine oil and oil filter element change
Engine oil change and oil filter element change must be made
simultaneously according to the following change schedule.
Engine oil draining
Wipe clean around the oil filler cap taking care so that no foreign
articles enter. Remove the filler cap.
It is advisable that draining be done while the engine is warm to
minimize the draining time.
Remove the oil pan drain plug and drain the engine oil completely.

Oil Filter Element Installation
Lightly apply engine oil to the O-ring.
Fig.8
Screw in the new cartridge hand tight as the O-ring comes in contact
with the engine block. Tighten a further 3/4 to 1 1/4 turns. DO NOT
overtighten.
Fill with new engine oil via the most convenient oil filler port.
Wait at least ten minutes until the oil drains down to the oil pan. Then
check the oil level with the dipstick.
Check after oil and filter changes
Oil leakage check:
• Run the unit for five to ten minutes, then visually check for oil
leakage.
Oil level recheck:
• Stop the engine for at least ten minutes.
Use the dipstick to recheck the oil level. If necessary replenish with
engine oil to the specified level
Engine oil additives
Engine oils contain a variety of additives. Your engine should not need
any extra additives if you use the recommended oil quality and change
intervals.
Used engine oil
Do not dispose of used engine oil (or any other oil) in a careless
manner such as pouring it on the ground, into sewers, or into streams
or bodies of water. Instead, recycle it by taking it to a used oil collection
facility which may be found in your community. If you have a problem
disposing of your used oil, it is suggested that you contact your local
Doosan branch or dealer. This also applies to diesel fuel which is
contaminated with water.
Discard used engine oil and other oils properly.
COOLING SYSTEM
Coolant change
The coolant must be changed at intervals of 1000 hours or twelve
months, whichever come first.
If the coolant becomes sludged up it will lead to engine overheating or
coolant blow-off from the radiator.
NOTE: For change intervals: Refer to maintenance schedule
section.
CAUTION: To help avoid the risk of being burned, do not drain
oil while the engine is still hot.
NOTE: Use a receptacle to catch the drained oil so that the
engine and equipment will not be contaminated.
NOTE: When the engine is started, the oil level will slightly drop
from the initial level as the oil fills the entire oil circuit.
CAUTION: Used engine oil contains harmful contaminants that
have caused skin cancer in laboratory animals. Avoid prolonged
skin contact. Clean skin and nails thoroughly using soap and
water - not mineral oil, fuels, or solvents. Launder or discard
clothing, shoes, or rags containing used engine oil.
