Auto-deceleration function
When the auto-deceleration function is ON, if the work
equipment and travel levers are returned to the N position,
the engine speed will drop after 4 seconds from the operat-
ing speed to idling speed.
This makes it possible to reduce fuel consumption.
If any lever is operated when the machine is in this condi-
tion, engine speed will return to the previous operating
speed to make it possible to perform operations.
1. When auto-deceleration switch (2) is pressed and the auto-
deceleration function is turned ON, the mode is displayed
in the center of the monitor display, and after two seconds,
the screen returns to the standard screen.
2. On the standard screen, the Auto-deceleration monitor
lights up.
(When the auto-deceleration is OFF, it does not light up.)
