1. Loosen stop lamp switch by rotating it counter-clockwise by
45#0#.
2. Loosen input rod lock nut (A), then rotate input rod, set pedal to
the specified height, and tighten lock nut (A).
CAUTION:
Confirm threaded end of input rod remains inside the cle-
vis.
3. Pull pedal by hand and hold it. Press stop lamp switch until its
threaded end contacts the stopper rubber.
4. While holding it against the stopper rubber, turn the switch clock-
wise by 45#O# and secure it.
