Preparation

Assembly

STEP 1 Assemble the rail and trolley

To prevent INJURY from pinching, keep hands and fingers away from the joints while assembling the

rail.

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 front rail has a rail tab. This tab

MUST be on the top of the rail when assembled.

1. Remove the straight door arm and hanging bracket packaged inside the front rail and set aside

for Installation Step 5 and 9. NOTE: To prevent INJURY while unpacking the rail carefully remove

the straight door arm stored within the rail section.

2. The rail sections have a groove on the sides near the bottom edge. Use these grooves to

align the rail sections. Slide the tapered ends into the larger ones. Tabs along the side will lock

into place.

3. As a temporary stop, insert a screwdriver into the hole in the second rail section from the motor

unit, 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 packiSng material. Snap them back into position as shown.

5. Slide the trolley assembly toward the screwdriver as shown.

6. Slide the chain spreader onto the rail until it stops.

TIP: Ensure the rail sections are aligned properly and the chain spreader has been installed

before fastening the rail to motor unit.

STEP 2 Fasten the rail to the motor unit

To avoid SERIOUS damage to garage door opener, use ONLY the 1/4"-20x1-3/4" self-threading

screws provided.

1. 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.

2. Ensure that the chain spreader is installed.

3. Place the rail onto the motor unit. Align the screw holes in the rail with the holes on top of the

motor unit.

4. Use a 1/4" socket to fasten the rail with the screws; DO NOT use any power tools. The use of

power tools may permanently damage the garage door opener.

approximately 12" (30 cm) of cable through the window. Allow it to hang until Assembly Step 4.

2. Remove the tape from the idler pulley. The inside center should be pre-greased. If dry, regrease

to ensure proper operation.

3. Place the idler pulley into the window as shown.

4. Secure idler pulley with clevis pin and ring fastener.

5. Rotate the pulley to be sure it spins freely.

6. Locate the rail tab. The rail tab is near the idler pulley on the front rail section. Use a flat head

screwdriver and lift the rail tab until the tab is vertical (90º).

3. With the trolley against the screwdriver, dispense the remainder of the cable/chain along the rail

toward the motor unit into the slot on the chain spreader, around the sprocket onto the chain

spreader and continuing to the trolley assembly. The sprocket teeth must engage the chain.

(Figure 2)

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 trolley thread shaft

STEP 5 Tighten the chain

1. Spin the inner nut and lock washer down the trolley threaded shaft, away from the trolley.

the inner nut to secure the adjustment.

Sprocket noise can result if the chain is too loose or too tight. When installation is complete, you may

notice some chain droop with the door closed. This is normal. If the chain returns to the position shown

when the door isopen, do not re-adjust the chain.
