ASSEMBLY STEP 1
Assemble the Rail and
Attach the Idler Pulley Bracket
To avoid installation difficulties, do not run the
garage door opener until instructed to do so.
1. Place the 3 rail sections on a flat surface for
assembly. The end sections are identical. The
center section must be positioned with the braces
against the end sections as shown.
Make sure the “directional arrow” on
the center section is pointing toward
the front (to door). Study the illustration
carefully.
2. Bolt rail sections together with the
hardware illustrated and from the
direction indicated. (When assembled,
rail has a front-to-back position
as shown.)
NOTE: If rail is not assembled exactly
as shown, trolley will not travel smoothly along
length of rail or it will hit against nuts.
3. Position the idler pulley bracket on the front end of
the rail as shown. Fasten securely with the
hardware provided.
NOTE: When tightening the bolts be sure to keep
bracket parallel to the rail. Otherwise, the rail may
bow when the opener is operated.
