When you see this safety symbol on the following pages, it will alert you to the possibility of damage

WARNING WARNING
CAUTION

3
• Lift the door about halfway as shown. Release the
door. It should stay in place, supported entirely by
its springs.
• Raise and lower the door to see if there is any
binding or sticking.
An unbalanced garage door might not reverse
when required and someone under the door
could be seriously injured or killed.
If your garage door binds, sticks or is out of
balance, call for professional garage door
service. Garage doors, door springs, cables,
pulleys, brackets and their hardware, are under
extreme tension and can cause serious injury or
death. Do not try to loosen, move or adjust them
yourself!
Ropes left on a garage door could cause
someone to become entangled and killed.
Remove all ropes connected to the door before
installing and operating the opener.
This product is for use on sectional garage
doors only. Serious personal injury could
result from the use of this product on one-
piece garage doors.
To avoid damage to the garage door and
opener, disable locks before installing and
operating the opener. Use a wood screw or nail
to hold locks in the "open" (unlocked)
position.
Operation at other than 120V 60 Hz will cause
opener malfunction and damage.
Before you begin, complete the following test to make sure your door is balanced and is not sticking or
binding. Identify the type and height of your door, any special conditions that exist, and any additional
materials that may be required by referring to the lists on page 4.

Slack in chain tension

Based on your particular requirements, there are
several installation steps which might call for
materials and/or hardware not included in the
carton.
• Step 1, page 8 - Look at the wall or ceiling above
the garage door. The header bracket must be
securely fastened to structural supports.
• Step 5, page 12 - Do you have a finished ceiling in
your garage? If so, a support bracket and
additional fastening hardware may be required.
• Safety reversing sensor, page 16 - Depending
upon garage construction, wood blocks may need
to be fastened to mounting locations before
sensors are installed.
• Step 10, page 17 - Alternate floor mounting of the
safety reversing sensor will require hardware not
provided.
• Step 11, page 19 - Do you have a steel, aluminum,
fiberglass or glass panel door? If so, horizontal
and vertical reinforcement is required.
• Look at the garage door where it meets the floor. It
must close on the floor all the way across. Other-
wise, the safety reverse system may not work
properly. See page 23. Floor or door should be
repaired.
• If your door is more than 7 feet high, see longer
rails available on page 30.

• The opener can be installed within 2 feet to the left or
right of the door center if there is a torsion spring or
center bearing plate in the way of the header bracket
or door bracket area. If your door has extension
springs, the opener must be installed in the center of
the door. See pages 8 and 19.
Do you have an access door in addition to the garage
door? If not, Model 1702 Outside Quick Release is
required. See page 30.
