3.6.2 Emergency shutdown
Under an emergency or special condition, make an emergency stop to avoid serious engine failure. Manually pulling
of the emergency stop handle can achieve an emergency shutdown.
3.7 Running-In of A New or Overhauled Engine
When the engine is first put into use or after being overhauled, run the engine for 60 hours (about 2,000 km) in
running-in condition and change its oil thereafter before running it in full load condition so as to improve its moving
parts working condition and its reliability and service life.
The way of running-in varies from one engine application and loading manner to another. In principle, engine speed
and load in running-in process will be increased gradually with the running-in going on. Load should be 50%-80% of
its full load, and speed should not exceed 80% of its rated speed.
Do not run the engine at idle or with low load for a long-time either in running-in period or normal working period
thereafter. Continuous running at idle should not be longer than 10 minutes to avoid early wear due to carbon deposit
or engine performance being affected.
