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 2 m), and the dozing depth to 300 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.
• When the design surface in the range of piling soil is not set, operate the blade by using blade control lever
to release the load.
METHOD FOR SCRAPING NATURAL GROUND
Natural ground scraping work is the operation to generate the inclined surface by scraping the soil on the slope.
