WARNINGCAUTION

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 doora, door springs, cables, pulleys, brackets and their hardware are under extreme tension and can cause serious injury or death. Do not fry to loosen, move or adjust them yourselfl

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,

Identify the type and height of your door and any special conditions that exist and any additional materials that may be required by referring to the lists on page 4 or page 5.

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:

Uft 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.
