AUTO-DECELERATION SWITCH
Auto-deceleration switch automatically lowers the engine
speed and turns on the function to reduce fuel consumption
when the control levers are at NEUTRAL position.
Auto-deceleration indication lamp lights up: Auto-deceleration
ON
Auto-deceleration indication lamp goes off: Auto-deceleration
OFF
Each time the switch is pressed, the auto-deceleration is
switched between ON and OFF.
REMARK
When the travelling on street mode is set, the auto-deceleration
function is automatically activated.
Avoid deactivating it. If the auto-deceleration function is deacti-
vated, when the drive pedal is released the engine rpm returns
to what was set with the hand throttle. This is not an anomaly.
Function of auto-deceleration
When the auto-deceleration function is ON, if the work equipment lever and travel lever are returned to NEU-
TRAL position, the engine speed will drop approximately after 4 seconds from the operating speed to idle
speed.
As a result, fuel consumption can be reduced.
If any lever is operated in this condition, engine speed will return to the previous operating speed, and you can
perform the operation.
