Operation & Maintenance Manual
Start and Shutdown
Start and Shut down of the Engine.
Preparing for Start
Check the following before starting the engine for the first time after purchase.
1. Before starting an engine, check the levels of fuel, coolant, and oil. Replenish those
fluids if required.
2. Ensure engine oil level is between the upper and lower limit of the oil level gauge.
The upper and lower limit of the oil level gauge indicate the maximum and minimum
of the engine oil level.
When replenishing engine oil, do not exceed the maximum on the oil
level gauge. Too much oil may cause damage to the engine.
3. Be careful not to mix foreign substances in fuel, engine oil, or coolant while injecting
the fluid. Keep the fluid clean while it is not in use. Use fuel, oil, and coolant
recommended by Doosan. Otherwise, critical damage to the engine may occur.
Starting the Engine
Observe the following when starting the engine.
1. For a cold start, start the engine after preheating it sufficiently through the glow plug.
After Starting the Engine
1. Operate engine at light load until engine has reached normal operating temperature.
2. Oil, air, or fuel leaks can cause a decrease in oil pressure. Oil leaks are especially
likely to cause the burning of bearings. As such, if oil, air, or gas leaks occur, check
the leaking parts and solve the problem.
During Operation
1. If oil pressure drops too low, it may cause abnormal wear and burning of bearings. If
oil pressure is too high, it may cause oil leakage.
2. Continuing to operate the engine after noises or vibrations coming from the engine
are noted may lead to serious engine damage. As such, if noises or vibrations come
from the engine, slowly decrease the rpm to stop the engine and examine the cause.
Shutdown
Do not suddenly shut down the engine after it was operated under high loads for a long period.
If oil burns because of heat sent from the high-temperature turbine blade to the bearing part,
the bearing metal and rotating shaft may burn. As such, if the engine was operated under
high loads for a long period, sufficiently run the engine at idle before shut down.
