WARNING
In the resting position, the distance from the centering shoe to the back plate is factory-set at 4.00”, which is appropriate for
most applications. If desired, this distance may be increased up to 4⅜” (± 1/16”). Increasing the distance will allow the turnstile
to rotate with less effort.
NOTE
If the distance is exceeded, self-centering may not operate correctly.
Issue
Solution
Reference
Customer would like the
turnstile to rotate with less
pushing force.
The pushing force required to rotate the turnstile is factory set to be
suitable for most installations. To lessen the pushing force required to
rotate the turnstile, adjust as follows:
1. Locate the lock bolt and lock nut on the back plate.
A. Loosen the lock nut with the 9/16” wrench while holding the lock
bolt in place with the 9/16” socket and socket wrench.
B. Once the lock nut has been loosened, unscrew the lock bolt 3 turns.
C. Confirm smoother operation. If no noticeable change is detected,
repeat steps A and B.
2. Once the self-centering tension has been adjusted, tighten all hardware.
Perform approximately 10 rotations to confirm that the roto self-centers
prior to closing the top channel cover.
