Operation
Loading dump truck
NOTE
Do not load the dump truck suddenly from a high position. If
the dump truck is loaded like this, the dump truck will suffer
impact load and there is danger that this may damage the
body.
Do not operate the dump or stop operations when the
engine is running at high speed. There is danger of impact
pressure being generated in the hydraulic equipment and
causing damage to the hydraulic equipment.
Do not shake the bucket violently to dump the load inside the
bucket. The machine will sway greatly and there is danger of
damage to the machine. In addition, there is danger of
impact pressure being generated in the hydraulic equipment
and causing damage to the hydraulic equipment.
When loading the dump truck, do not pushed forcibly with
the bucket. This machine and the dump truck will suffer
impact shock, and this will cause damage. When pushing
the load with the bucket to prevent rocks from falling, carry
out the operation softly.
When loading large rocks, first load with sand or soil to act
as a cushion. Then load the large rocks on top. If large rocks
are loaded directly, they will cause deformation or damage to
the dump body.
1. When loading the dump truck, load at a low point that does
not hit with the dump truck or dilution.
2. After completing the loading, if there is danger of rocks fall-
ing off, push the load softly with the bucket.
