In order to ensure the proper operation of your safety
reverse feature, replace the assembly instructions in
your Owner’s Manual with the following assembly steps.
WARNING
ASSEMBLY STEP 1
Assemble the Rail & Install
the Trolley
To avoid installation difficulties, do not run the
garage door opener until instructed to do so.
The front rail has a cut out “window” at the door end
(see illustration). The hole above this window is
larger on the top of the rail than on the bottom. A
smaller hole 3-1/2" (8.9 cm) away is close to the rail
edge. Rotate the back rail so it has a similar hole
close to the opposite edge, about 4-3/4" (12 cm)
from the far end. A 3-piece rail uses two back rails.
1. Align the rail sections on a flat surface exactly as
shown and slide the tapered ends into the larger
ones. Tabs along the side will lock into place.
2. Place the motor unit on packing material to protect
the cover, and rest the back end of the rail on top.
For convenience, put a support under the front
end of the rail.
3. As a temporary trolley stop, clamp a locking pliers
onto the rail, 8" (20 cm) from the end of the back
rail, as shown.
4. Check to be sure there are 4 plastic wear pads
inside the inner trolley. If they became loose
during shipping, check all packing material. Snap
them back into position as shown.
5. Connect the inner and outer trolleys as shown.
6. Slide the trolley assembly along the rail from the
front end to the locked pliers.

shown. Tighten securely with a 1/4"-20 lock nut.
• Remove the two bolts from the top of the motor
unit.
• Attach spreaders to the U bracket by snapping
them into place.
• Place the U bracket, flat side down, on the motor
unit and align the bracket holes with the screw
holes. Fasten with the previously removed screws.
• Align the rail assembly with the top of the motor
unit. Slide the rail end onto the U-bracket, all the
way to the stops that protrude on the top and sides
of the bracket.

and pulley. Tighten with a 3/8" lock washer and nut
underneath the rail until the lock washer is
compressed.
• Rotate the pulley to be sure it spins freely.
• Insert a 1/4"-20 x 1-3/4 bolt into the trolley stop
hole in the front of the rail as shown. Tighten
securely with a 1/4"-20 lock nut.

1. Pull the cable around the idler pulley and toward
the trolley.

notches.
• Slide clip-on spring over cap and onto pin
notches until both pins are securely locked in
place.

remainder of the cable/chain along the rail toward
the motor unit and around the sprocket. The
sprocket teeth must engage the chain.
4. Check to make sure the chain is not twisted, then
connect it to the threaded shaft with the
remaining master link.
5. Thread the inner nut and lock washer onto the the
trolley shaft.
6. Insert the trolley threaded shaft through the hole
in the trolley. Be sure the chain is not twisted.
7. Loosely thread the outer nut onto the trolley shaft.
8. Remove the locking pliers.
9. Align the tabs on the sprocket cover with the
slots in the mounting plate. Squeeze
cover and insert tabs in slots.
To avoid possible SERIOUS INJURY to fingers from
moving garage door opener:
• ALWAYS keep hand clear of sprocket while
operating opener.
• Securely attach sprocket cover BEFORE operating.
