SECTIONAL DOOR
ONE-PIECE DOOR
An unbalanced garage door might not reverse
when required and someone under the door
could be seriously injured or killed.
If your garage door binds, sticks or is out of
balance, call for professional garage door
service.
Garage doors, door springs, cables,
pulleys, brackets and their hardware are under
extreme tension and can cause serious injury
or death.
Do not try to loosen, move or adjust
them yourself!
Ropes left on a garage door could cause
someone to become entangled and killed.
Remove all ropes connected to the door before
installing and operating the opener.
To avoid damage to the garage door and
opener, disable locks before installing and
operating the opener. Use a wood screw or nail
to hold locks in the "open" (unlocked) position.
Operation at other than 120V 60 Hz will cause
opener malfunction and damage.
Identify the type and height of your door and any
special conditions that exist and any additional
materials that may be required by referring to the lists
on page 4 or page 5.
Before you begin, complete the following test to
make sure your door is balanced, and is not
sticking or binding:
• Lift the door about halfway as shown. Release the
door. It should stay in place, supported entirely by
its springs.
• Raise and lower the door to see if there is any
binding or sticking.

The front rail has a cut out “window” at the door end
(see illustration). The hole above this window is
larger on the top of the rail than on the bottom. A
smaller hole 3-1/2" away is close to the rail edge.
Rotate the back rail so it has a similar hole close to
the opposite edge, about 4-3/4" from the far end. A
3-piece rail uses two back rails.
1. Remove the straight door arm and clevis pin
packaged inside the front rail and set aside for
Installation Step 12.
2. Align the rail sections on a flat surface exactly as
shown and slide the tapered ends into the larger
ones. Tabs along the side will lock into place.
3. Place the powerhead on packing material to
protect the cover, and rest the back end of the rail
on top. For convenience, put a support under the
front end of the rail.
4. As a temporary trolley stop, clamp a locking pliers
onto the rail, 8" from the center of the idler pulley
hole, as shown.
5. Check to be sure there are 4 black plastic wear
pads inside the inner trolley. If they became loose
during shipping, check all packing material. Snap
them back into position as shown.
