To prevent damage to garage door and opener:
• ALWAYS disable locks before installing and operating
the opener.
• ONLY operate garage door opener at 20V, 60 Hz to
avoid malfunction and damage.
To prevent possible SERIOUS INJURY OR DEATH:
• ALWAYS call a trained door systems technician if
garage door binds, sticks, or is out of balance. An
unbalanced garage door may not reverse when
required.
• NEVER try to loosen, move or adjust garage door, door
springs, cables, pulleys, brackets or their hardware, all
of which are under EXTREME tension.
• Disable ALL locks and remove ALL ropes connected to
garage door BEFORE installing and operating garage
door opener to avoid entanglement.
Preparing your garage door
Before you begin:
• Disable locks.
• Remove any ropes connected to garage door.
•Complete the following test to make sure your
garage door is balanced and is not sticking or
binding:
. 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.
Tools needed
During assembly, installation and adjustment of the
opener, instructions will call for hand tools as

SECTIONAL DOOR INSTALLATION
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 – 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 0 – Depending upon garage
construction, extension brackets or wood blocks
may be needed to install sensors.
• Installation Step 0 – 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 7702CB Outside Quick
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 /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 ).
• 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 and .
• If your door is more than 7 feet high, see rail
extension kits listed on Accessories page.

need additional mounting hardware for the door
bracket (Step ).

ASSEMBLY STEP 1
Assemble the T-Rail and
Attach the Belt Pulley Bracket
To avoid installation difficulties, do not run the
garage door opener until instructed to do so.
1. Align the four T-rail sections on a flat surface
exactly as shown.Center sections are
interchangeable. Front and back sections are also
interchangeable for ease of assembly.
2. nsert the carriage bolts so the square
bolt necks seat in the square holes
in the T-rail sections and pass
through the round holes in the rail
braces. Make sure bolt necks are
seated in the square holes and rails
are aligned before you tighten lock
nuts. mproper assembly can cause
jerky trolley operation, noise and/or
nuisance door reversals.
3. Assemble lock nuts, ensure alignment
and tighten.
NOTE: If T-rail is not assembled exactly as shown,
trolley will not travel smoothly along length of rail or
it will hit against nuts.
4. Position the belt pulley bracket on the front end of
the T-rail as shown. Fasten securely with the
hardware shown.
NOTE: When tightening the bolts, be sure to keep
bracket parallel to the rail. Otherwise, the rail may
bow when the opener is operated.

screwdriver stop. NOTE: If trolley hits against any
nuts on the T-rail, the bolts and nuts were attached
from the wrong side and must be repositioned.
Review Assembly Step 1.
• nsert a 5/16"-18x7/8" hex bolt into the trolley stop
hole in the T-rail as shown. Tighten securely with a
5/16" lock washer and nut. This screw limits trolley
travel in the DOWN direction.

retaining slot on top of the trolley (Figure ).
2. Grasp the clip connector at the end
of the belt and slip it through the belt
pulley bracket from behind, around
the pulley and toward the trolley.
3. Fasten the belt clip connector to the
trolley clip with a master link:
• Push pins of master link bar
through holes in trolley clip and belt
clip connector.
• 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.
4. With the trolley against the screwdriver,
dispense the belt along the rail and around
the motor unit sprocket. The sprocket teeth
must engage the belt (Figure 2).
5. Use the second master link to connect the belt
to the flat end of the trolley threaded shaft
(Figure ). Check to make sure the belt is not
twisted
6. Remove the screwdriver.
SETTING THE TENSION
. Insert the trolley threaded shaft through the hole in
the trolley.
2. Hold the belt at the trolley shaft to avoid twisting as
