CHAPTER 4 – OPERATING INSTRUCTIONS
4-15
After preparing the drainage, the next step is to prepare
and level the road bed.
Maintain the frame straight, circle centered and blade al-
most perpendicular to the machine, in such a way that the
material leaves from both sides and cuts the crest of the
road rather high to permit drainage on both sides.
In subsequent passes, angle the blade between 10° and
25° tilting it a little toward the front to permit the material
to roll toward the road shoulders.
Make these passes at relatively high speeds, so that the
loose material passes under the blade before touching
the ends.
On the nal pass, for each road shoulder position the bla-
de end bit in line with tandem, so that the rear tires can
compact the material that may slide off the sides of the
blade.
