Note: In temperatures from 0 to 60 °C (32 to 140 °F), the warm-up time is approximately five minutes. In temperatures below 0 °C (32 °F), additional warm-up time may be required.Note: Ensure that the self-test for the monitoring system is completed before you operate the engine under load.
Operate the engine at low idle rpm for five minutes. Perform these checks during the warm-up:
Check for any fluid leaks and for any air leaks.
Check all the gauges.Observe the gauges and record the data frequently while the engine is operating. Comparing the data over time will help to determine normal readings for each gauge. This will also help detect abnormal operating developments. Investigate any significant changes in the readings.
After the engine has idled for five minutes and the inspections have been made, increase the engine speed to 1/2 rated rpm.
To avoid engine overheating and possible engine damage, ensure that water discharge is visible at the sea water outlet and/or the water flow is not restricted.If the water flow is restricted and/or water discharge is not visible at the sea water outlet, follow the recommended procedure.
Observe the water discharge at the sea water outlet. If water discharge is not visible or the water flow is restricted, perform the following procedure:
Stop the engine immediately.
Inspect the inlet screen and the sea water strainer for debris. Remove any debris that is found.
Inspect the cooling system and the auxiliary water pumps for evidence of leaks.
Check for any fluid leaks and for any air leaks.
