TRANSMISSION AR 1167684 - Caterpillar

Stopping the engine immediately after it has been working under load can result in overheating and accelerated wear of the engine components. Allow the engine to engine cool down before stopping. Avoiding hot engine shutdowns will maximize turbocharger shaft and bearing life.
Emergency Stopping
Emergency shutoff controls are for EMERGENCY use ONLY. DO NOT use Emergency shutoff devices or controls for normal stopping procedure.
Make sure that any external system components that have been operating to support engine operation are secured after any stop.Emergency Stop Buttons

There may be several ways to shut off your engine. Make sure the shutoff procedures are understood. Use the following general guidelines for stopping the engine.Generator Set Engines
If the ECS is in the AUTO position and the remote contact opens, the engine will run for a pre-programmed cool down period. This will only occur when the cool down mode is used. If the cool down mode is not used, the engine will shut off immediately.1. Open the main electrical circuit breaker to remove the load.2. The engine should be run for a cool down period before being shut off. This can be accomplished with the COOLDOWN STOP function, or the operator can control the cool down and shut off.To use the COOLDOWN/STOP function, turn the ECS to the COOLDOWN/STOP position. The engine will operate for a pre-programmed time period. The timer will activate the fuel shutoff after the cool down period.Alternatively, after removing the
