NOTICE
If you go past the chisel mark, repeat the procedure
beginning with the blade rotated 1 foot clockwise beyond
the chisel mark.
If the value is within 1 or 2 degrees of 0, then rotation is accurately
compensated and no repairs are needed!
Figure 7-18.
If the value is more than beyond 2 degrees, then the problem is one or
more of the following:
Figure 7-19.
• Excess "slop" in the pin between the grader's hydraulic swivel
and the hose tray.
• Hose tray is bent and the guide rods are no longer attached to the
circle.
• The hole where guide rod is attached to circle is worn so the
guide rod is no longer held tight.
• Guide rods are weak and have too much flex.
These are physical wear areas that must be repaired for System Five
to cut accurate cross slope.
