Step 3: Attach Unit to Front Wall Bracket
Raise the front end of the opener and attach
it to the front wall bracket, using the ¼” x 4”
hex head bolt and the supplied ¼” plastic
insert nut. Take care not to over tighten nut;
tighten only until end of bolt is flush with out-
side of nut.
NOTE: If you have a torsion spring
counter-balance system, it will be
necessary to raise the motor Head
Assembly of the opener and support it
on a step-ladder to attach the front end
of the opener to Wall Bracket.
Step 4: Positioning the Motor End of Operator
CAUTION: To prevent damage to steel, aluminum, fiberglass or glass panel doors do not rest the opener of the
door without using a 2” x 4” at least 12” long.
Raise the motor end of the opener and support it
so you can open the door to its fully open position.
You may need help raising motor end if ladder is
not high enough.
Open the door and place a 2” x 4” piece of wood
along the top section of the garage door. Rest the
double rails on the 2” x 4”, as illustrated.
Support the top section of the door to prevent
sagging.
Step 5: Mounting Motor End of Opener
Align the center of opener tracks with
the center line previously marked on
the top section of the garage door to
ensure rail will be parallel with the di-
rection of door travel.
Use perforated hangers (cut as
needed to adjust length) from ceiling
or beams to hang opener at motor end
(be sure to locate and mount to solid
structural beams, as illustrated).
Pre-drill with 3/16” drill bit and use 1/4”
x 1-1/2” lag screws to ensure a rigid
mount. Attach opener to hangers.
WARNING: Do not use gear cap
bolt or nut for hanger attachment,
this may cause sprocket and
chain misalignment, resulting in
damage or possible injury!
Note: Hanging brackets should be at an angle to provide rigid support. If hangers have no angle or if you use
long hangers, cross brace the hangers to eliminate the possibility of sway during operation of the opener.
