1. Lift the door about halfway as shown. Release
the door. If balanced, it should stay in place
supported entirely by its springs.
2. Raise and lower the door to see if there is any
binding or sticking.
If your door binds, sticks, or is out of balance, call
a trained door systems technician.

Planning
Identify the type and height of your garage door.
Survey your garage area to see if any of the
conditions below apply to your installation. Additional
materials may be required. You may find it helpful to
refer back to this page and the accompanying
illustrations as you proceed with the installation of
your opener.
Depending on your requirements, there are several
installation steps which may call for materials or
hardware not included in the carton.
• Installation Step 1 - Look at the wall or ceiling
above the garage door. The header bracket must
be securely fastened to structural supports.
• Installation Step 5 - Do you have a finished ceiling
in your garage? If so, a support bracket and
additional fastening hardware may be required.
• Installation Step 10 - Depending upon garage
construction, extension brackets or wood blocks
may be needed to install sensors.
• Installation Step 10 - Alternate floor mounting of
the safety reversing sensor will require hardware
not provided.
Do you have an access door in addition to the
garage door? If not, Model 53702 Emergency Key
Release is required. See Accessories page.
Look at the garage door where it meets the floor.
Any gap between the floor and the bottom of the
door must not exceed 1/4". Otherwise, the safety
reversal system may not work properly. See
Adjustment Step 3. Floor or door should be
repaired.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical reinforce-
ment is required (Installation Step 11).
• The opener should be installed above the center of
the door. If there is a torsion spring or center
bearing plate in the way of the header bracket, it
may be installed within 4 feet to the left or right of
the door center. See Installation Steps 1 and 11.
• If your door is more than 7 feet high, see rail
extension kits listed on Accessories page.
SECTIONAL DOOR INSTALLATION
Horizontal and vertical reinforcement
is needed for lightweight garage doors
(fiberglass, steel, aluminum, door with
glass panels, etc.). See page 24 for details.

Planning (continued)
ONE-PIECE DOOR INSTALLATIONS
• Generally, a one-piece door does not require
reinforcement If your door is lightweight, refer to
the information relating to sectional doors in
Installation Step 11
•Depending on your door's construction, you may
need additional mounting hardware for the door
bracket (Step 11)
Without a properly working safety reversal system,
persons (particularly small children) could be
SERIOUSLYINJUREDor KILLEDby a closing garage
door.
• The gap betweenthe bottom of the garage door and
the floor MUST NOTexceed1/4". Otherwise,the safety
reversal system may not work properly.
• The floor or the garage door MUSTbe repaired to
eliminate the gap.

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" away is close to the rail edge.
Rotate the back rail so # has a similar hole close to
the opposite edge, about 4-3/4" from the far end. A
3-piece rail uses two back rails.
1. Remove the straight door arm and clevis pin
packaged inside the front rail and set aside for
Installation Step 12.
2. 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.
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 trolley stop, clamp a locking pliers
onto the rail, 8" from the center of the idler pulley
hole, as shown.
5. Check to be sure there are 4 black 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. Connect the inner and outer trolleys as shown.
7. Slide the trolley assembly along the rail from the
back end to the locked pliers.

bolt hole on the back end of the rail as shown.
Tighten securely with a 1/4"-20 lock nut.
• Remove the two screws 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.

• Remove the tape from the idler pulley. The inside
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 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"-20xl-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.

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.
3. 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 injury to fingers from moving
garagedoor opener:
• ALWAYSkeephand clear of sprocket while operating
opener.
• Securelyattach sprocket cover BEFOREoperating.
