To Assemble Rail and Opener
1. Prepare the rails as shown in Fig.1.
2. Connect the rails starting with the header segment. Insert
the tapered ends into open ends, apply any additional force
necessary by tapping the rail on padded flooring. Ensure
the end segment has trolley stop bolt facing up. Make sure
the rails are securely joined together as shown.
3. Slide the trolley onto the rail from the header segment.
Make sure the arrow is pointing towards the door as shown
in Fig.1.
4. Connect the rail assembly to the rail bracket on the opener.
To Assemble the Header Section of Rail
Follow steps shown in Fig.2:
1. Remove the “trolley shaft and cable” from the chain carton
and lay it beside the rail assembly. Hold cable eyelet on the
end of cable and thread about 20” (50cm) through the slot
on the Header Segment of the rail.
2. Insert the pulley into the opening while the cable is hanging.
3. Secure the pulley by inserting the 3/8” x 1-3/4” clevis pin
through the top of the rail.
4. Lock the clevis pin with a hitch pin. Rotate the pulley to
ensure it spins smoothly.
Refer to Fig.3 to connect the trolley shaft to the trolley. Slide both
the trolley shaft and trolley towards each other. A “click” will be
heard when they are connected.
To Link Cable with Chain
Refer to Fig.4. Place the chain carton beside the rail, hold the
“chain to cable connector” and pull about 8” (20cm) of chain from
the box. Thread the chain to cable connector onto the trolley
shaft so that they are loosely linked together.
