Auto-deceleration function
When the auto-deceleration function is ON, if the work equipment and travel levers are returned to the N posi-
tion, the engine speed will drop after 4 seconds from the operating speed to idling speed.
This makes it possible to reduce fuel consumption.
If any lever is operated when the machine is in this condition, engine speed will return to the previous operat-
ing speed to make it possible to perform operations.
