4) Mount the front mounting bracket (Item 9) to the mounting
pad as shown in Figure 8. The location of the door’s torsion
shaft may prevent you from placing the mounting pad in the
location shown. Mount the pad as close as possible to three (3)
inches above the door’s high arc point.
6) Swing the operator to a horizontal position above the door
guide rails (high enough to raise the door) and temporarily
secure by suspending from the ceiling with a suitable rope or
chain or support from the floor to the operator. Now open the
garage door slowly, being careful not to dislodge the temporary
support. Lower the operator until it is level. Make sure the
operator is aligned with the center of the door and the bottom of
the rail is at least 2” above the high arc of the door. See Figure
10.
5) With the door in the down position, loosely attach the rail
support to the mounting bracket using two (2) bolts, lockwashers
and nuts (Items 4, 5, 6). See Figure 9.
7) Tighten securely the two (2) bolts, nuts and washers that
were loosely attached in Step 5. See Figure 11.
