In addition to the following, it is possible to further increase the range of applications by using various attachments.
Shovel Work
This is suitable for digging a place which is higher than the
machine's position. It is most efficient if the arm s digging angle
is from vertical to 60i forward, and the arm cylinder is used
effectively.
A simple method of seeing the angle of the bucket teeth to the
ground surface is to use the teeth and the part of the rear
bucket shown in the diagram on the right. Check that the part
of the rear bucket is more or less parallel to the teeth.
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 if the excavator is placed beside the dump
truck for loading. This way means more earth can be loaded
more effectively than by a loader working behind the truck.
