Grading Operation - Hitachi ZAXIS 120-6 class Operator's Manual

Grading Operation

Operate the boom, arm, and the bucket in such a way so that
the bucket teeth move horizontally, constantly keeping them
perpendicular to the ground at the grading operation.
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.
1. Operate arm roll-in function while slowly raising the
boom. Once the arm moves past the vertical position,
slowly lower the boom to allow the bucket to maintain a
smooth surface.
2. Reverse the directions in step 1 to perform arm roll-out
operation.
3. Perform slope finishing work using the same procedure
described in steps 1 and 2.
