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 areas that are lower than the
machine.
When the condition of the machine is as shown in the diagram on
the right (angle between [bucket cylinder and link] and [arm
cylinder and arm] is 90°), the maximum excavation force is
obtained from the pushing force of each cylinder.
When excavating, use this angle effectively to optimize your
working efficiency.
The range for excavating with the arm is from a 45° angle away
from the machine to a 30° angle towards the machine.
There may be some differences depending on the excavation
depth, but try to stay within the above range rather than operating
the cylinder to the end of its stroke.
Shovel Work
A shovel is suitable for excavating at a position higher than the
machine. Shovel work is performed by attaching the bucket in the
reverse direction.
Ditching Work
Ditching work can be performed efficiently by attaching a bucket
which matches the digging operation and then setting the tracks
parallel to the line of the ditch to be excavated.
To excavate a wide ditch, first dig both sides and then finally
remove the center portion.
