OPERATION OPERATIONS AND CHECKS BEFORE STARTING ENGINE
189
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).
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.
If the bucket is lowered strongly to the ground, the resistance will
be increased and it will be difficult to remove the pins.
2. Remove the stopper bolts and nuts, then remove pins (A) and
(B) and remove the bucket.
NOTICE
After removing the pins, make sure that they do not
become contaminated with sand or mud and that the seals of
bushing on both sides do not become damaged.
3. Align the arm with holes (1) and the link with holes (2), then
install pins (A) and (B).
