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" ( .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.
. 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.

• 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.

center should be pre-greased. If dry, regrease to
ensure proper operation.
• Place the idler pulley into the window as shown.
• Insert the idler bolt from the top through the rail
and pulley. Tighten with a /8" lock washer and nut
underneath the rail until the lock washer is
compressed.

ASSEMBLY STEP 4
Install the Chain/Cable
and Attach the Sprocket Cover
1. Pull the cable around the idler pulley and toward
the trolley.
2. Connect the cable loop to the retaining slot on the
trolley, as shown:
• From below, push pins of master link bar up
through cable loop and trolley slot.
• Push master link cap over pins and past pin
notches.
• Slide clip-on spring over cap and onto pin
notches until both pins are securely locked in
place.
. With the trolley against the pliers, dispense the
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 I JURY to fingers from
moving garage door opener:
• ALWAYS keep hand clear of sprocket while
operating opener.
• Securely attach sprocket cover BEFORE operating.

Tighten the Chain
• Spin the inner nut and lock washer down the
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" (1 cm) 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.
NOTE: You may notice loosening of chain after
Adjustment (Test the Safety Reversal System).
Check for proper tension and readjust chain if
necessary. Then repeat Adjustment.

6. Locate the door control push button within sight of
the door at a minimum height of 5 feet where small
children cannot reach and away from all moving
parts of the door. Operating a door control push
button that is located out of sight of the door can
lead to SERIOUS PERSO AL I JURY or DEATH
from entrapment.
7. Install the User Safety Instruction Label on the wall
adjacent to the control button and the Maintenance
Instruction Label in a prominent location on the
inside or alongside of the door.
8. Upon completion of the installation, the door must
reverse when it comes in contact with a 2x4 board
inserted between the wall and the door or between
the swinging door sections (see page 8).
9. Do not wear watches, rings or loose clothing while
installing or servicing an opener. Jewelry or loose
clothing can be caught in the mechanism of the door

ADJUSTMENT
Follow the Adjustment Steps below
for proper testing of the Safety
Reverse System.
1. The opener must reverse if the door comes in
contact with an obstruction. A closing door should
reverse with little effort, and open completely.
Refer to Adjustment Step 2 in Owners Manual
for instructions.
2. At completion of installation of opener and testing
of reversing feature in #1 above, the 1 inch
reversal test must be completed. (Use 2x4 board
laid flat against the wall or door edge.)
• On a sliding door door, place a 2x4 board
between the door and wall of a closing door.
Door must reverse on the board and open
completely. Repeat at opposite wall if two
openers are installed.
• On a swing out door, insert a 2x4 board between
the closing door sections. Door sections must
reverse and swing open completely.
• If the door stops on the obstruction, it is not
traveling far enough in the closing direction.
Increase the DOWN limit adjustment screw
counterclockwise 1/4 turn. Repeat test.
• When the door reverses on a 2x4 board, remove
the obstruction and run the opener through
complete travel cycle to test adjustment.
• If the door will not reverse after repeated
adjustment attempts, call for trained door
systems technician.
IMPORTANT SAFETY CHECK
Repeat Adjustment Steps in Owners Manual
after:
• Each adjustment of door arm length, force controls
or limit controls.
• Any repair to or adjustment of the garage door
(including springs and hardware).
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY I JURED or KILLED by a closing garage door.
• Too much force on garage door will interfere with
proper operation of safety reversal system.
• EVER increase force beyond minimum amount
required to close garage door.
• EVER use force adjustments to compensate for a
binding or sticking garage door.
• If one control (force or travel limits) is adjusted, the
other control may also need adjustment.
• After A Y adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with one-inch high object (or 2x4 laid flat)
on floor.
