5. Rotate the circle back clockwise continuously and smoothly to a
45 degree angle.
The values next to rotation should decrease from 45 degrees to a -
45 degrees angle in a smooth transition. If they do not, refer to the
procedures, in step 4.
Figure 7-16.
6. The Rotation Sensor Test can also be used to indicate whether
servicing of the circle, hose tray or guide rods is required.
Rotate the circle counterclockwise until chisel mark on the circle
lines up with the "A"-frame.
