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 dooropener 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. 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.
4. As a temporary stop, insert a screwdriver into the hole 10" (25 cm) from the front end of the rail,
as shown.
5. 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.
6. Slide the trolley assembly toward the screwdriver as shown.
7. Slide the chain spreader onto the rail until it stops.

protection bolt hole on the back end of the rail as shown. Tighten securely with a 1/4"-20 lock nut.
DO NOT overtighten.
2. Use the carton to support the front end of the rail.
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. Fasten the rail with the screws; DO NOT use any power tools. The use of power tools may
permanently damage the garage door opener.

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.

STEP 5 Tighten the chain
1. Spin the inner nut and lock washer down the trolley threaded shaft, away from the trolley.
2. To tighten the chain, turn the outer nut in the direction shown.
3. When the chain is approximately 1/4" (6 mm) above the base of the rail at it's midpoint, re-tighten
the inner nut to secure the adjustment.
Sprocket noise can result if the chain is too loose.
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 is open, do not re-adjust the chain.
NOTES:During future maintenance, ALWAYS pull the emergency release handle to disconnect the
trolley before adjusting the chain.
You may notice loosening of the chain after Adjustment Step 3 (Test the Safety Reversal System). Check
for proper tension and readjust chain if necessary. Then repeat Adjustment Step 3.
