Rod does not adjust properly, it is either too loose or too tight. (Either the auxiliary will not follow because the rod slips, or with the auxiliary motor tipped up the rod does not extend.)
Move the inner rod in or out of the outer rod. If the inner rod will not move, remove the white plastic cap on the outer rod and back off the Allen screw inside the detente tube. As soon as the inner rod is movable, extend or insert the inner rod until you feel the detente pin drop into one of the grooves in the inner rod. At this point, tighten the Allen screw until it is snug. Now back off the Allen screw one and one-half turns. This will adjust the rod so that approximately 20 pounds of pressure is needed to make it adjust.
If you want to check the accuracy of this adjustment, you can extend the rod, place the end of the rod on a bathroom scale, and try to compress the rod. Check the scale reading to see how much pressure was needed to compress the rod. If further adjustments are necessary, turn the Allen screw by one-eighth of a turn increments. It changes very quickly.
