drive arms and connecting links are perpendicular and clear of door and track. If necessary, slide the
operator base forward or backward.
Proper positioning of the operator is critical to the life of the arm bearings. Bending of the drive arms will
place stress on the bearings reducing their operating life.
Once the operator base is in correct position, drill the holes to permanently fasten the rear of the operator
and tighten all mounting bolts.
