Stopping the engine immediately after it has been working under load, can result in overheating and accelerated wear of the engine components. Refer to the following procedure, to allow the engine to cool, and to prevent excessive temperatures in the turbocharger housing (if equipped), which could cause oil coking problems. |
- Park the machine on level ground. Refer to Operation and Maintenance Manual, "Stopping the Machine" for the recommended procedure.
- To allow the engine to cool, operate the engine at low idle for 5 minutes.
- Turn the engine key switch to the off position.
Note: If the "Regen Active" indicator is illuminated, do not shut off the engine. Refer to Operation and Maintenance Manual, "Monitoring System" for more information on indicators.
Note: This machine is equipped with a separate engine enclosure cooling fan that may continue to operate even after the engine is stopped and the engine start switch has been placed in the OFF position. Leaving the machine unattended with systems still running may result in property damage if there is a system malfunction.
The Delayed Engine Shutdown allows the engine to run for a time after the key switch has been turned to the off position. This is to cool the engine and system components.
Note: The DEF purge process will run for 2 minutes once the engine is shutdown and must complete. The purge process may occur during delayed engine shutdown. Do not turn off battery disconnect switch during the purge process. Do not turn off the battery power disconnect switch until the battery disconnect switch indicator lamp has turned off. If the purge process does not complete, a diagnostic code will become active.
Note: There may be regulations that define the requirements for the operator and/or support personnel to be present when the engine is running.

Delayed Engine Shutdown - The delayed engine shutdown indicator will illuminate or the following text will be displayed, ENGINE COOL DOWN ACTIVE. |
Delayed engine shutdown will run whenever the exhaust temperature is above a threshold at engine shutdown. Delayed engine shutdown will run for a minimum of 76 seconds and will continue to run until the engine and system components are cooled.
Note: At any time during a delayed engine shutdown, the engine start switch may be turned to the ON position. The engine may be placed back into service.
