1. Close the garage door completely.

long or damaged, you may need to cut the torsion bar. Ensure the collar does not
touch the bearing plate.
3.
Use a level to position and vertically align the garage door opener. Verify the mounting
bracket is located on a solid surface such as wood, concrete or door/fl ag bracket.
4. When the garage door opener is properly aligned, mark the mounting bracket holes.
If necessary, tighten collar screws on the torsion bar to hold garage door opener in
place while marking holes.

5. Remove the garage door opener from torsion bar. Drill 3/16 inch pilot holes at the
marked locations. Drill through steel plate if necessary.

bracket. Securely tighten collar screws to the torsion bar to 12-14 ft./lbs. of torque

NOTE: You may need to manually raise the door slightly in order to reach the
set screws.
