ASSEMBLY STEP 1
Attach the Rail to the Motor Unit
To avoid installation difficulties, do not run the garage
door opener until instructed to do so.
• Remove the two washered bolts mounted in top of
motor unit.
• Position rail at a 45˚ angle to opener so one hole in rail
and motor unit line up.
• Thread one of the washered bolts part way in.
Use only these bolts! Use of any other bolts will cause
serious damage to door opener.
• Align rail and styrofoam over sprocket. Cut tape from
rail, chain and styrofoam.
• REMOVE STYROFOAM.
ASSEMBLY STEP 2
Attach the Chain to the Sprocket and
Install the Sprocket Cover
• Position chain over the sprocket. If necessary, loosen
the outer nut on the trolley to obtain more chain slack.
• Insert the second washered bolt. CAUTION: Use only
the bolt previously removed from motor unit!
• Tighten both bolts securely through the rail into the
motor unit as shown.
• Install the sprocket cover: Insert the back tab in the slot.
Squeeze the cover slightly and insert the front tab in the
slot on the mounting plate.
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.

ASSEMBLY STEP 3
Tighten the Chain
• Spin the inner nut and lock washer down the trolley
threaded shaft, away from the trolley.
• To tighten the chain, turn outer nut in the direction
shown (Figure 1).
• When the chain is approximately 1/2" (13 mm) above
the base of the rail at its midpoint, re-tighten the inner
nut to secure the adjustment.
Sprocket noise can result if 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 in Figure 2 when the door is
open, do not re-adjust the chain.
NOTE: During future maintenance, ALWAYS pull the
emergency release handle to disconnect trolley before
adjusting chain. You may notice loosening of chain after
Adjustment Step 3 (Test the Safety Reversal System).
Check for proper tension and readjust chain if necessary.
Then repeat Adjustment Step 3.

IMPORTANT INSTALLATION INSTRUCTIONS

INSTALLATION STEP 1
Determine the Header Bracket
Location
Installation procedures vary according to garage door
types. Follow the instructions which apply to your door.
1. Close the door and mark the inside vertical centerline of
the garage door.
2. Extend the line onto the header wall above the door.
You can fasten the header bracket within 4 feet
(1.22 m) of the left or right of the door center only if
a torsion spring or center bearing plate is in the
way; or you can attach it to the ceiling (see page 9)
when clearance is minimal. It may be mounted on
the wall upside down if necessary, to gain
approximately 1/2" (1 cm).
If you need to install the header bracket on a 2x4
(on wall or ceiling), use lag screws (not provided)
to securely fasten the 2x4 to structural supports as
shown here and on page 9.
3. Open your door to the highest point of travel as shown.
Draw an intersecting horizontal line on the header wall
above the high point:
• 2" (5 cm) above the high point for sectional door and
one-piece door with track.
• 8" (20 cm) above the high point for one-piece door
without track.
This height will provide travel clearance for the top edge
of the door.
NOTE: If the total number of inches exceeds the height
available in your garage, use the maximum height
possible, or refer to page 9 for ceiling installation.
To prevent possible SERIOUS INJURY or DEATH:
• Header bracket MUST be RIGIDLY fastened to structural
support on header wall or ceiling, otherwise garage door
might not reverse when required. DO NOT install header
bracket over drywall.
• Concrete anchors MUST be used if mounting header bracket
or 2x4 into masonry.
• NEVER try to loosen, move or adjust garage door, springs,
cables, pulleys, brackets, or their hardware, ALL of which
are under EXTREME tension.
• ALWAYS call a trained door systems technician if garage
door binds, sticks, or is out of balance. An unbalanced
garage door might not reverse when required.
