3. The value next to rotation should display 0 degrees. If it does not
read 0 degrees, recalibrate the Rotation Sensor in its current
position and re-enter the System Test Mode.
Figure 7-14.
4. Proceed by rotating the circle counterclockwise continuously and
smoothly to about a 45 degree angle (the right side of the blade
should be approximately 1 foot from the front tire.)
The value next to "Rotation" should display the increase from 0
degrees to 45 degrees in a smooth transition:
• If the numbers jump erratically as the circle is being rotated,
then the Rotation Sensor is not working properly.
• If the numbers do not change, as the circle is being rotated,
remove the Rotation Sensor and check to make sure the pin
has not fallen out.
