Grading Operation - Hitachi ZAXIS 30U-5N Operator's Manual

Grading Operation

Use the blade for soil refilling and general grading operations
after excavation. Grading operation can be also performed by
operating the boom, arm, and bucket simultaneously.
IMPORTANT: Do not pull or push dirt with the bucket
when traveling. Excess force will be applied on each
part, and the machine may be damaged.
When grading by operating the boom, arm, and bucket
simultaneously:
1. When grading from the forward to the backward, slowly
roll in the arm while slightly raising the boom. As soon
as the arm passes the vertical position, slowly lower the
boom so that the bucket can be horizontally moved.
2. When grading from the backward to the forward,
operate the arm and bucket rolled back as described
step 1.
Do the slope finishing work in the same procedure as
described in steps 1 and 2.
