8. Reattach the nose cone.
Note: The cap's lifetime is
1 year after the first
reading has been taken.
Install by the date printed
on the packaging. 9. Reattach the RDO sensor and white PVC fitting. Do not completely tighten
the white fitting. You will need to adjust the sensor so that it touches the
brush in the next section.
3.1.2 Adjusting the Wiper Brush
1. With the white PVC fitting slightly loose, move the RDO sensor toward or
away from the brush. The brush should lightly sweep the sensor cap, but
not brush too hard or miss the cap completely.

2. Tighten the white PVC fitting when the sensor is in the proper location.
3. If the brush is too high or too low, loosen the set screw on the brush
mechanism and slide the brush up or down as needed. You may also
rotate the brush while it is loose to check the position of the sensor.
Tighten the set screw when you have completed the adjustment.
