Modifying spring tension
By removing the drive stopper from the main pinion splines and repositioning, you can increase or
decrease the spring tension for windy conditions, or increased latch pressure. The drive unit must be
removed from the header to make this adjustment Note: This will also change the manual opening and
closing force (Check your code settings).
1. To lock the d
rive from moving manually rotate the drive coupler until a ¼” X 20 NC threaded hole
is exposed through the cast housing coupler window (figure 4 A&B). Thread a machine screw in
this hole.
2. Now slide the door arm on the main spline pinion and rotate until the stop block is 180 degrees
from the casting stopper lug.
3. Lightly undo the Allen cap screw in the stop block and before removing mark the spline position of
the pinch gap on the stop block (figure 5).
4. You can now remove the stop block and reinstall MAXIMUM 4-6 splines in either direction from
the factory setting.
5. Moving the stop block forward to the opening travel will decrease the tension and moving the stop
block away from the opening travel will increase the tension (figure 6).
6. Slide the stop block down the splines to the casting and re-tighten the Allen cap screw.
7. Reinstall the drive unit into the header and with the door arm slipped back onto the splines, rotate
the main pinion till the stop block engages the casting stopper.
8. You can now reinstall the door arm in the correct position for backstop and re-tighten. You may
have to adjust your back-check, latch activation
