MACHINE OPERATIONS AND CONTROLS
REMARK
•
If some place higher than the design surface is left at 1 time dozing, travel on that place several times so
that such place can be built as designed.
•
If the soil in front of the blade disappears and no load to the blade in the middle of carrying the soil, drive
the machine in reverse once and get the load to the blade again.
•
When the design surface is deep, offset the design surface upward and cut the ground by each 150 to
300 mm in steps, you can operate smoother and more stable.
METHOD FOR SCRAPING SOILS IN SHORT DISTANCE
In this method, carrying distance is short and operation is efficient.
Enable "Smooth Start" and select "Cutting".
1.
Start dozing by the blade automatic control from the position near piling position (U).
2.
Gradually retract the starting point of dozing and repeat traveling backward and forward.
(T) Design surface
•
As standard, limit the distance of each reverse travel to a half of the machine overall length (L) (approxi-
mately 3 m), and the dozing depth to 350 mm. Operator should adjust the dozing distance and dozing
depth, depending on the type of soil.
•
When driving the machine in reverse at the place where the cutting angle changes, the operator comfort
may be bad. In this case, set the cutting depth to 200 mm or less.
For details of setting of the cutting depth, see "METHOD FOR ADJUSTING CUT/FILL OFFSETS" and
"METHOD FOR ADJUSTING CUT/FILL OFFSETS (POP-UP MENU)".
•
If the type of soil is not uniform, blade may cut too deep at position (A) where the surface changes from
downhill to level ground. Use the blade control lever to raise the blade.
•
At position (B) where the blade pushes the carried soil to the soil piled at the last time, the track may slip
and damage the surface of the ground. Use the blade control lever to raise the blade.
