Grading Operation; Avoid Abusive Operation - Hitachi EX27U Operator's Manual

GRADING OPERATION

In most cases, use the blade for soil refilling and general
grading operations. When needed, the front attachment
can be used to perform grading operations.
IMPORTANT: Don't pull or push dirt with the bucket
when traveling.
Position the arm slightly forward of the vertical position with
bucket rolled back, as shown.
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.
Grading operation can be more precisely done by operat-
ing the boom, arm and bucket simultaneously.

AVOID ABUSIVE OPERATION

Don't use travel as an additional digging force. Severe
machine damage may result.
Don't raise rear of machine to use the machine's weight as
additional digging force. Severe machine damage may re-
sult.
