mechanical or from electric shock. Read the instructions carefully.
Mechanical
serious injury
3
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.
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.
Identify the type and height of your door, any special
conditions that exist, and any additional materials that
may be required.
Test Your Door for Balance
Before you begin, complete the following test to make
sure your door is balanced, and is not sticking or
binding:
• 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.

IMPORTANT INSTALLATION INSTRUCTIONS
To reduce the risk of severe injury or death to persons:
1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS
2. Install only on a properly balanced and lubricated garage door. An improperly balanced door may not
reverse and could result in severe injury or death. Repairs to cables, spring assemblies and other
hardware must be made by a professional service person before installing opener.
3. Disable all locks and remove all ropes connected to the garage door before installing the opener. Ropes
connected to a garage door can cause entanglement and death.
4. If possible, install door opener 7 feet or more above floor with the manual release handle mounted 6
feet above the floor.
5. Do not connect the opener to power source until instructed to do so.
6. Locate the Door Control within sight of the door at a minimum height of 5 feet where small children
cannot reach and away from all moving parts of the door.
7. Install the User Safety Instruction Label on the wall adjacent to the control button and the
Maintenance Instruction Label in a prominent location on the inside of the garage door.
8. Upon completion of the installation, the door must reverse when it comes in contact with a one-inch
high object or a 2x4 laid flat on the floor.
9. Do not wear watches, rings or loose clothing while installing or servicing an opener. Jewelry or loose
clothing can be caught in the mechanism of the garage door or the opener.
• Align rail brackets to end of rail assembly, as shown.
• Insert two 1/4"-20 x 5/8" hex screws and lock nuts.
Tighten securely with a 7/16" socket.
