2. ADJUSTING THE DRIVE HUB
The drive hub must be adjusted so the following actions occur.
- When the correct buttons of the combination have been depressed, the turn
knob must rotate 90° to the right (clockwise) to the stop position without
restriction.
- When the turn knob is at the 90° position (vertical), the exit device latch
should be completely retracted and the combination buttons will have
automatically reactivated for the next entry.

1) In order to determine the proper setting for the exit device being used, insert
a flat bladed screwdriver into the horizontal slot of the exit device hub.
2) Rotate the screwdriver to the right (clockwise) until the exit device latch is
fully retracted. Note the position of the screwdriver (45º, 60º, or 90º). Once
your setting has been determined, adjust the drive hub (if necessary) as
described below.
The factory setting of the drive hub is shown in Figures 2-1 and 2-2.
