WARNING: If your garage has no service entrance door, Model 1702AML Outside Quick Release must be installed. This accessory allows manual operation of the garage door from outside in case of power failure. Keep garage door balanced. Sticking or binding doors must be repaired. Garage doors, door springs, cables, pulleys, brackets and their hardware are under extreme tension and can cause serious personal injury. Do not attempt to loosen, move or adjust them. Call for garage door service. Do not wear rings, watches or loose clothing while installing or servicing a garage door opener. To avoid serious personal injury from entanglement, remove all ropes connected to the garage door before installing the door opener. Installation and wiring must be in compliance with your local building and electrical codes. This is a class 2 double insulated product, connection to earth is not required or provided. Lightweight doors of fiberglass, aluminum or steel must be substantially reinforced to avoid door damage. The best solution is to check with your garage door manufacturer for an opener installation reinforcement kit. The safety reverse system test is very important.

Repeat the test once a month and make any needed adjustments. This unit should not be installed in a damp or wet space.
Fasten the child warning label adjacent to the lighted door control button as a reminder of safe operating procedures. Disengage all existing garage door locks to avoid damage to garage door. Any door control buttons (if installed) MUST be located where the garage door is visible, but out of the reach of children. Do not allow children to operate push button(s) or remote control(s). Serious personal injury from a closing garage door may result from misuse of the opener. Activate opener ONLY when the door is in full view, free of obstructions and opener is properly adjusted. No one should enter or leave the garage while the door is in motion. Do not allow children to play near the door.
These safety alert symbols mean WARNING a personal safety or property damage instruction. Read these instructions carefully.

If the unit stops before it reaches the Open or Close Limit repeat the process. The green LED will stop flashing when the Force has been learned
The safety reverse system test is important. Garage door must reverse on contact with a 40mm obstacle laid flat on the floor. Failure to properly adjust opener may result in serious personal injury from a closing garage door. Repeat test once a month and adjust as needed. Procedure: Place a 40mm obstacle (1) laid flat on the floor under the garage door. Operate the door in the down direction. The door must reverse on the obstruction. If the door stops on the obstruction, it is not traveling far enough in the down direction. Move Close Limit closer to door

When the door reverses on the 40mm obstacle, remove the obstruction and run the opener through a complete travel cycle. Door must not reverse in closed position. If it does, adjust Limit and repeat safety reverse test. Place 20kg at the center of the door and ensure that the door will not move up more than 500mm. SAVE THESE INSTRUCTIONS
