MACHINE OPERATIONS AND CONTROLS
Select "Simple Grading".
REMARK
When "Simple Grading" is selected, you cannot set the Smooth
Start and the blade load mode.
At the place where the angle of design surface changes sharply, operate the decelerator/brake pedal to de-
crease the travel speed.
When the dozing mode is set to "Simple Grading", the blade edge always moves along the design surface. Even
if a load is applied to the blade, the blade does not rise automatically. Therefore, use this method for the finish-
ing operation under a light load.
(T) Design surface
If the slope length is shorter than the machine overall length, the finishing accuracy may become worse at a
concave inflection point. In such case, do as follows.
•
Use both of the blade automatic control and manual blade control by blade control lever.
•
Change the working direction of the machine.
WHEN FINISHING CONVEX INFLECTION POINT
•
At convex inflection points (A) and (B), perform finishing work by operating the blade with the blade control
lever or by traveling transversely.
•
The brake mode is recommended to maintain the speed of the work equipment. If the brake mode is used,
the travel speed can be decreased without decreasing the engine speed.
