General Operations instruction
4.10.1.
Backhoe operation
The backhoe is suitable for digging below the machine.
Maximum bucket thrust is achieved when
the machine is in the position shown in the
diagram to the right, i.e., when the bucket
cylinder is at 90° to the connecting rod and
the boom cylinder is at 90° to the boom.
The digging range of the boom is from an
angle of 45° away from the machine to an
angle of 30° toward the machine.
This may vary depending on the digging
depth, but try to operate within this range
rather than operating the cylinder to the
end of its stroke.
ATTENTION: It is best to excavate hard rocky ground after it has been
smashed by other means. This will not only reduce the damage to the machine,
but is also more economical.
4.10.2.
Loading operation
It is more efficient to park the dump
truck in a place where the operator
can easily see it at a low slew angle.
It is easier and more convenient to
load from the rear of the dump truck
than from the side of the dump truck.
