OPERATIONS AND CHECKS BEFORE STARTING ENGINE OPERATION
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.
LEVELLING WORK
Can be carried out with work equipment or dozer blade (if fitted).
