OPERATING THE MACHINE
Loader and Dump Truck Combination Method

WARNING:

Always maintain a flat and clean work site surface.
Avoid rapid turns and/or sudden braking while
raising the lift arm with the bucket loaded to
prevent the machine from tipping over.

Do not insert the bucket into a loading face at fast
speed, possibly resulting in an accident.
A loader carries out loading and carrying, and dumping is
carried out by a dump truck. Either V- or I-shape loading
method is used in this method. Depending on the work
site conditions and matching with available trucks, select
the most efficient method.
V-Shape Loading
1. Park a dump truck in a spot located at approx. 60°
angle toward the loading face. After loading material,
travel the wheel loader in reverse and turn its direction
so that the wheel loader faces the parked dump truck
at a right angle. Then, travel forward to carry material
onto the dump truck.
2. Position the wheel loader so that the material can be
loaded around the center of the dump body. In case
the dump body is longer than twice the bucket width,
load from the front to rear position of the dump body
in order.
3. When dumping sticky material such as clay, move the
bucket lever back and forth to lightly hit the bucket to
the stoppers.
Use a small steering angle to operate the machine
efficiently.
4. Before raising the lift arm to the maximum height with
the bucket full, lightly tap the bucket while low to
stabilize the material in the bucket and help prevent
the material from spilling from the backside of the
bucket.
I-Shape Loading
Park a dump truck in a direction parallel to the loading
face. After loading material into the bucket, move the
wheel loader straight in reverse. Then, move a dump truck
to a spot between the loading face and the wheel loader.
Move the wheel loader forward to load material into the
dump truck body.
