CLAMP-PIPE 1279133 - Caterpillar

Note: After the engine has been installed or rebuilt, carefully monitor the engine in order to detect any unusual engine performance.
Operate the engine at low idle for two to three minutes. Allow the jacket water temperature to begin to rise before increasing the engine rpm. Note: More warm-up time may be necessary when the ambient temperature is below −18 °C (0 °F).
Turn the air supply to the air starting motor OFF (if equipped).
Make another walk-around inspection. Inspect the engine for fluid leaks and air leaks. Note: For instructions on engaging the driven equipment, see the literature that is provided by the OEM of the vessel.
Ensure that the gauges are in the normal ranges for the engine rpm. After verifying that the engine systems are normal, engage the driven equipment. Begin operating the engine at low load. Continue to check the gauges and the driven equipment. Operate the engine at a low load until the engine reaches normal operating temperature. The engine should reach operating temperature before the vessel enters open water.The engine will reach normal operating temperature faster when the engine is operated at low rpm and low power demand. This procedure is more effective than idling the engine with no load.
After normal oil pressure is reached and the jacket water temperature rises, the engine may be operated at full load. Increase the load, as required.
