6. Engine automatic warming-up, overheat prevention function, turbo protect function
Function
• If the coolant temperature is low, this automati-
cally raises the engine speed to warm up the en-
gine after it is started. In addition, if the coolant
temperature rises too high during operations, it
reduces the load of the pump to prevent over-
heating.
• To protect the turbocharger bearing during cold
weather, the engine speed is kept below the
fixed speed when the engine is started.
