RECOMMENDED APPLICATIONS

In addition to the following, it is possible to further increase the range of applications by using various attachments.
BACKHOE WORK
A backhoe is suitable for excavating at a position lower than
the machine.
When the condition of the machine is as shown in the diagram
at right, each cylinder's maximum pushing excavation force is
obtained when the bucket cylinder and link, arm cylinder and
arm are at 90º.
When excavating, use this angle effectively to optimize your
work efficiency.
The range for excavating with the arm is from a 45º angle away
from the machine to a 30º angle toward the machine.
There may be some differences depending on the excavation
depth, but try to stay within the above range rather than operat-
ing the cylinder is the end of its stroke.
DITCHING WORK
Ditching work can be performed efficiently by attaching a
bucket to match the width of the ditch and then setting the
tracks parallel to the line of the ditch to be excavated.
To excavate a wide ditch, first dig out both sides and then
finally remove the center portion.
LOADING WORK
In places where the swing angle is small, work efficiency can
be enhanced by locating the dump truck in a place easily visi-
ble to the operator.
Loading is easier and capacity greater if you begin from the
front of the dump truck body than if loading is done from the
side.
