WARNING
If the lever is operated when engine speed has been reduced by the autodeceleration function, engine
speed will go up abruptly; therefore, the levers should be operated with care.
Working tools are controlled by the levers positioned to the operator's right and left. The left lever controls the 2nd
boom and the turret rotation, while the right lever controls the 1st boom and the bucket. When the levers are
released, they automatically return to a neutral position and the working tools remain in the position in which they
were stopped. The movement of the levers and the corresponding movement of the tools are illustrated in the
following diagrams.
