The machine is prepared for several different type
of optional equipment to perform many types of
work. Only the simplest operations are described

Backhoe work is digging the material at a lower
level than the machine is located.
When the angle between bucket cylinder and links,
dipper arm cylinder and dipper arm is set to 90°
respectively, the working efficiency of each cylinder
will be at its maximum. Take advantage of this angle
to improve the work efficiency. The range for
effective digging is when the dipper arm is between
30° forward and 45° rearward. There may be a little
difference according to digging depth. Do not use
the cylinder up to its stroke end, but only within this
range.

Install a proper bucket for ditching. Place the
machine where the ditching is performed
effectively.
In case of a wide ditch, dig both sides in first, and
then dig the center area.

Position the hauler or truck so as to achieve a small
swing movement and good visibility for the operator
to work effectively.
Also load over the rear side of the dump truck rather
than over the side, as this makes the operator work
easier and increases efficiency.
