Stepladder
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.
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.
• 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!
