ASSEMBLY STEP 1

Assemble the Rail and

Attach the Belt Pulley Bracket

To avoid installation difficulties, do not run the garage door opener until instructed to do so.

1.Align the four rail sections on a flat surface exactly as shown. Center sections are interchangeable. Front and back sections are also interchangeable for ease of assembly.

2.Insert the carriage bolts so the square bolt necks seat in the square holes in

the rail sections and pass through the round holes in the rail braces. Make

sure bolt necks are seated in the square holes and rails are aligned

before you tighten lock nuts. Improper assembly can cause jerky trolley operation, noise and/or nuisance door reversals.

3. Assemble lock nuts, ensure alignment

and tighten.

NOTE: If rail is not assembled exactly as shown,

trolley will not travel smoothly along length of rail

or it will hit against nuts.

4. Position the belt pulley bracket on the front end of
