Rotate arch to the desired “home” position (position you want arch to return to).
- Re-attach and lower stop collar directly behind pin of center stop plate and between legs of torsion spring. Tighten
stop collar on arch with end of pin of collar approximately .02” below top surface of center stop plate.
Important:
end

Stop collar.
Spring centering kit will limit rotation of arch to
90 degrees of rotation in each direction, no more
. There is no way
to increase rotation in one direction more than 90 degrees and still have spring return. However one can limit rotation
to less than 90 degrees in one or both directions by adding 1 or 2 more Stop Collars (75000-655W).
