Before excavation, the arm cylinder should have angle with the arm as 90°, bucket with ground to be
excavated as 30°. Only in such case, can each cylinder have the max. excavating force. It is suitable for
relatively hard soil, so as to decrease the excavating resistance.
To excavate any soft soil, bucket should be angled with the soil to be 60°, increasing the work efficiency.
Keep the angle between bucket base and the bevel at 30°, and retract the arm to start work.
