OPERATION
FINISHING LEFT ROAD SHOULDER
1. Operate the drawbar shift cylinder to set the circle to the left
end.
2. Set so that the left end of the blade is in line with the outside of
the left tire. Set the blade so that the soil is discharged between
the 2 wheels. (The soil can be moved more smoothly if the
blade is at a small propulsion angle.)
3. Align the center of the machine with the line of the soil
discharged when digging the ditch.
4. Operate the left and right blade lift cylinders to keep the blade
horizontal and at the desired digging depth.
5. Lean the front wheels slightly to the right.
