FOR METAL BUILDINGS ONLY: A strong mounting
surface for the operator front header bracket is
needed. On the wall above the center stile, weld or
bolt a 2"x2"x1/4" piece of angle iron or another
suitable, heavy-duty material as shown in Figure 2.
6. Draw a vertical line on header (or reinforcement
material) above center stile of door.
7. Raise the door to its high arc point. Use a
carpenter's level to locate high arc point on wall
above door center stile as shown in Figure 3. Make
a horizontal line, intersecting the vertical centerline
mark.
8. Close the door and refer to Figure 4. Position
operator chassis on the floor with the bottom edge
of header bracket 2" above horizontal mark and
centered on vertical line. Mark mounting holes.
FOR METAL BUILDINGS: Drill 3/8" holes for
fastening bolts. FOR CONCRETE BUILDINGS: Drill
3/8" holes for anchor bolts, following manufacturer's
instructions.
NOTE: Be sure header bracket is level before
tightening the bolts.
