DIAL 4988337 - Caterpillar

Stopping the engine immediately after the engine has been working under load, can result in overheating and accelerated wear of the engine components.Avoid accelerating the engine prior to shutting down the engine.Avoiding hot engine shutdowns will maximize turbocharger shaft and bearing life. Also, selective catalytic reduction component life.
Note: Individual applications will have different control systems. Ensure that the shutoff procedures are understood. Use the following general guidelines in order to stop the engine.
Remove the load from the engine. Reduce the engine speed to low idle. Allow the engine to idle for 5 minutes in order to cool the engine.
Stop the engine after the cool down period according to the shutoff system on the engine and turn the ignition keyswitch to the OFF position. If necessary, refer to the instructions that are provided by the OEM. Note: Some applications the engine will continue to operate after the keyswitch is turned to the OFF position. The engine will operate for a short time in order to allow engine components to cool.
Allow at least 2 minutes after the engine has stopped before you turn the battery disconnect switch to OFF. Disconnecting the battery power too soon will prevent purging of the DEF fluid lines after the engine is shut down. Also, during the 2 minutes the engine electronic control module is active, storing information from the engine and aftertreatment sensors. Delayed Engine Shutdown (if Equipped)
The delayed engine shutdown allows the engine to run for a time after the engine start switch is turned to the OFF position in order to cool the system components. The engine start switch key may be removed.Note: There may be regulations that define the requirements for the operator and/or support personnel to be present when the engine is running.
Leaving the machine unattended when the engine is running may result in personal injury or death. Before leaving the machine operator station, neutralize the travel controls, lower the work tools to the ground and deactivate all work tools, and place the lever for the hydraulic lockout control in the LOCKED position.
Leaving the engine unattended while running may result in property damage in the event of a malfunction.Note: An authorized dealer can change the maximum run time value up to 30 minutes but the default setting is 10 minutes.An override can be enabled so that the delayed engine shutdown will not operate. Overriding delayed engine shutdown may reduce engine and system component life. The override is operated by the keyswitch.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.
