8. After securing the wall mounting bracket, allow the motor to rest on floor and raise the front end of the rails and
secure (but not tighten) with 5/16" bolts and nuts (Figure 9). If torsion hardware is preventing the rails from lining-
up with the wall bracket, secure temporarily with cord.
9. Hoist rear of operator using block & fall or other suitable means above level of horizontal door tracks and
temporarily secure in place using rope or chain. Tighten front end bracket bolts.
10. Carefully open door by hand and move rear of operator so that it is directly over center of door, with
approximately 3" clearance between door and bottom of operator rails (Figure 10).
11. Hanging brackets may now be affixed from ceiling to operator (Figure 11). Two or more holes are provided in
frame of operator for this purpose. Take care that unit remains centered over door during installation of hangar
brackets. After vertical drops are made and secured, side braces should be installed.
12. Approximately 5 feet (1.5 m) from forward end of rails, locate set of 3/8" holes for angle iron braces to secure
rails. Two drops pieces should be installed at this point to further strengthen installation (Figure 11).
