USE OF GENUINE PARTS
An engine consists of many parts which are mechanically
harmonized. To prevent engine faults in advance and use
engines with best performance for a long period,
maintenance and replacement of expendable parts
should be conducted regularly.
Use of genuine parts is recommended. Using
unauthorized or remanufactured parts may cause critical
damage and faults to engine for which Doosan shall not
be held liable.
ENGINE MAINTENANCE
PREVENTION OF DAMAGE AND ABRASION
Using an engine for any purposes other than the
designed purpose may cause critical faults to the engine
for which Doosan shall not be held liable. For details
concerning the usage and purpose of the engine, please
direct questions to Doosan Sales Team. Do NOT adjust,
convert, or change the ECU without Doosan
authorization.
If a problem is found in an engine, figure out and solve
the cause to prevent the critical faults in advance. Use of
genuine parts is recommended. Using unauthorized or
remanufactured parts may cause critical damage and
faults to engine for which Doosan shall not be held liable.
Consider the following while managing engines:
1. Use clean, specified, and qualified fuel only. Use fuel
recommended in this Operation and Maintenance
Manual.
CAUTION
Using inappropriate or unspecified fuel may cause
critical damage and faults in engine performance.
2. Do not operate an engine without lubrication oil or
coolant. Use only the products (engine oil, cooling
water, anticorrosive agent, and etc.) recommended
by Doosan.
3. Always keep surroundings of the engine clean.
4. Use fuel recommended in this Operation &
Maintenance manual.
5. Conduct inspections and exchanges regularly
according to the regular inspection table.
6. If the engine is overheated, do not stop it immediately,
but operate it at idle status for five minutes or more to
lower the engine temperature to the proper level.
WARNING
If the radiator cap is opened while the engine is still
hot, hot water will spurt out and may cause burns.
7. Check the engine oil level on a flat surface. Do not
exceed the maximum of the oil level gauge.
CAUTION
Immediately replenish engine oil when the engine oil
level is below the lower limit of the engine oil gauge.
8. If there are gauges for battery, oil pressure, coolant
and temperature, check if they indicate a normal
status.
9. Do not operate engine without coolant.
CAUTION
Always use coolant mixed with antifreeze. If coolant
without antifreeze is used, the coolant may freeze
causing the coolant passage in the cylinder block to
freeze and damage the engine.
