Break-in Period of Engine
Doosan engines are subjected to a final approval test to ensure the provision of high quality
engines before being shipped. However, engines are not operated for a long period of time in
this test. Therefore, new engines require a break-in period during the initial 50 hours after
delivery. By properly breaking-in an engine, the highest levels of engine performance can
be maintained long term.
If the engine's bearings are not properly broken in, they may be easily damaged and the
lifetime of the engine may be shortened by overloading or high speeds. In order to prevent
this, please follow the guidelines below for the initial 50 hours after delivery of new engine.
1. Fully warm up the engine until the engine temperature reaches the normal operation
condition, before starting operation of the engine.
2. Do not overload the engine or operate it at too high RPM.
3. Do not operate the engine with high speed at idle.
4. Do not rapidly start up or shutdown.
5. Do not operate the engine with less than 70% of the engine load.
6. Inspection, check, and repair of engines should be managed by officially certified
technicians at certified service centers in compliance with corresponding rules.
