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, mainte-
nance and replacement of expendable parts should be
conducted regularly.
Use of genuine parts is recommended. Using unautho-
rized or remanufactured parts may cause critical damage
and faults to engine for which Doosan shall not be held
liable.
