1. WHEN AUTO DECEL LAMP ON
If all the work equipment control levers including swing and travel levers are at neutral for at least 4
seconds, CPU controller drives the accel actuator to reduce the engine speed to 1200rpm. As the
result of reducing the engine speed, fuel consumption and noise are effectively cut down during non-
operation of the control levers.
When the auto decel lamp is turned off by pressing the auto decel switch or any control lever is
operated, the reduced engine speed rises up to the speed set before deceleration in a second.
2. WHEN AUTO DECEL LAMP OFF
Auto deceleration function is not activated, and the engine speed can be set as desired by power
mode switches and engine speed switches on the cluster.
