OPERATION OPERATION

DITCHING WORK
Ditching work can be performed efficiently by attaching a bucket
to match the width of the ditch and then setting the wheels parallel
to the line of the ditch to be excavated.
To excavate a wide ditch, first dig out both sides and then finally
remove the center portion.
LOADING WORK
In places where the swing angle is small, work efficiency can be
enhanced by locating the dump truck in a place easily visible to
the operator.
Loading is easier and capacity greater if you begin from the front
of the dump truck body than if loading is done from the side.
REPLACEMENT AND INVERSION OF BUCKET
WARNING
●
When knocking the pin in with a hammer, metal particles
may fly and cause serious injury, particularly if they get
into your eyes. When carrying out this operation, always
wear goggles, helmet, gloves, and other protective
equipment.
●
When the bucket is removed, place it in a stable condi-
tion.
Stop the machine on a firm, flat surface. When performing joint
work, make clear signals to each other and work carefully for
safety’s sake.
REPLACEMENT
1. Place the bucket in contact with a flat surface.
REMARK
When removing the pins, place the bucket so that it is in light
contact with the ground.
