Stopping the engine immediately after the engine has been operating under a load can result in overheating and accelerated wear of the engine components.Allow the engine to gradually cool before stopping the engine.
Note: Remove the load at a rate that will avoid detonation.
Disengage the driven equipment.
For generator set engines, open the main circuit breaker.
For industrial engines, unload the compressor or pump. Disengage the clutch (if equipped). Place the transmission and/or other attachments for the power take-off in NEUTRAL. Note: Extended idling can cause excessive oil consumption and related problems. See this Operation and Maintenance Manual, "Engine Operation" topic (Operation Section).
Reduce the engine rpm to low idle. Note: If the cooldown feature is not utilized, operate the engine at low idle rpm for a cooldown period before stopping the engine. If the engine has been operated at a low load, operate the engine at low idle for approximately 30 seconds before stopping the engine. If the engine has been operated at a high load, operate the engine at low idle for one minute before stopping the engine.
Use one of the following methods in order to stop the engine:
Turn the engine control switch to the "COOLDOWN/STOP" position. If the cooldown feature is utilized, the engine will operate for a programmed period of time before the engine stops. Otherwise, the engine will immediately shut off.
Turn the engine control switch to the "OFF/RESET" position. The engine will immediately shut off.
If the engine control switch is in the "AUTO" position, open the remote start/stop initiate contact. If the cooldown feature is utilized, the engine will operate for a programmed period of time before the engine stops. Otherwise, the engine will immediately shut off. The engine will coast to a stop. Ensure that any system that provides external support to the engine is secured after the engine is stopped.
