ENGINE STOPPING
Make sure that all of the control levers on the equipment are in
NEUTRAL position.
Before stopping the engine, cool down the engine by operating
it at low idle speed about five minutes.
In this operation, check the engine noise and the engine oil
pressure for abnormalities.
In the turbocharged engine, if the engine is stopped
instantaneously, a dry condition produced by high temperature
will take place in the turbocharger rotating parts which may
cause lack of lubrication. This will result in turbocharger failure.
To stop the engine, turn the starter switch key to OFF position.
Switch off the battery (if so equipped).
NOTICE:
Leaving the starter switch key in the DRIVE position for a
long while after the engine has been stopped, will
discharge the batteries wastefully.
