SHOVEL WORK
This is suitable for excavating at a position higher than the machine.
Shovel work is performed by attaching the bucket in the re-
verse direction.
DITCHING WORK
Ditching work can be performed efficiently by attaching a buck-
et which matches the digging operation and then setting the
tracks parallel to the line of the ditch to be excavated.
To excavate a wide ditch, first dig both sides and then finally re-
move 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 visi-
ble to the operator.
Loading is easier and capacity greater if you begin from the
rear of the dump truck body than if loading is done from the
side.
EFFECTIVE USE OF HYDRAULIC EXCAVATOR
Operation for reducing fuel consumption
(Carbon dioxide emissions reducing operation)
The operating methods for reducing fuel consumption are as follows.
• Avoiding unnecessary engine idle running
• Avoiding hydraulic relief
• Running at low engine speed
• Reducing excavation at high position
• Operation at minimum swing angle
• Traveling at low engine speed
We can provide our users the training for operating methods to increase the productivity and to reduce the fuel
consumption. Contact your Komatsu distributor for details.
