Attaching Opener to Rail
Tools Needed:
3/8” Socket
Ratchet Wrench
IMPORTANT: THE DRIVER GEAR IN THE
OPENER MUST BE PROPERLY ALIGNED
WITH THE SPROCKET/ COUPLING COGS IN
THE RAIL ASSEMBLY AND THE MOUNTING
BOLTS FULLY TIGHTENED, BEFORE
POWERING UP THE OPENER. NEGLECTING
TO DO THIS WILL RESULT IN GEAR FAILURE.
Before assembly, align sprocket/ coupling
cogs to match notches of driver gear. Rotate
the motor spline to position driver gear so
the nearest notch in driver gear is directly
behind motor spline, as illustrated.
NOTE: Do not rotate more than 1/2 turn.
Place opposite end of rail on temporary
support approximately 6” in height.
Proceed with attaching rail to opener,
ensuring proper engagement between
sprocket/coupling cogs and driver gear
notches. Realign if necessary, making sure
to keep any rotation only to the nearest
notch. Using the (4) pre-attached
1/4”-20 x 5/8” hex head bolts, assemble
rail to opener using 3/8” socket; tighten
securely.
NOTE: Do not plug the opener power cord
into electrical outlet until opener is fully
installed and you are instructed to do so in
this manual.
