It is important in a normal shutdown that the engine be idled under no load conditions at half-speed or less
for at least three to five minutes. This allows lubricating oil and coolant to carry heat away from the combustion
chamber, pistons, valves and exhaust system. Sudden shutdown results in extreme localized heat-rise with
potential engine damage.
Shutdown is accomplished by PRESSING THE STOP BUTTON and holding it until engine stops.
