Disengage the driven equipment. Unload the compressor or pump.
Disengage the clutch (if equipped).
Place the transmission and/or other attachments for the power take-off in NEUTRAL.
Reduce the engine rpm to low idle. 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 three to five minutes before stopping the engine.
Turn the engine control switch to the stop position. The engine will coast to a stop. Ensure that any system that provides external support to the engine operation is secured after the engine is stopped.
