MACHINE OPERATIONS AND CONTROLS OPERATION
SIDE DITCHING WORK
Ditching work can be performed in a narrow space by combin-
ing swing and boom swing operations.
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 becomes greater if you place
the machine at the rear of the dump truck than if loading is
done from the side.
LEVELING WORK
Use the blade for back filling and leveling work after digging the
ground.
