IMPORTANT INSTALLATION INSTRUCTIONS
To reduce the risk of severe injuryor 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 emergency 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 door control 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,

If the header bracket is not rigidly fastened to
a structural support on the header wall or
ceiling, the safety reverse system may not
work properly (see page 30). The door might
not reverse when required, and could cause
serious injury or death.
The garage door springs, cables, pulleys,
brackets and their hardware are under extreme
tension. Do not attempt to loosen, move or
adjust them yourself. Serious personal injury
or death could result. Call for professional
garage door service.
