WARNING
•
The garage door opens rapidly, and can cause serious
injury or death.
•
Keep the path clear.
•
Position the ladder to the side of the Power Head so it is
clear of all moving parts of the Opener and the door.
•
Set the door Opener to use the minimum force needed
to open the door.
NOTE
•
Little effort is required to turn the Force
Adjusting Knobs.
•
If the door stops moving while opening or
closing, adjust the Open Force or Close Force
Controls slightly clockwise (to slightly
increase the force) and retry the step.
•
The Open Force and Close Force Controls are to
be set to the minimum force necessary to
ensure the door smoothly opens fully and
closes completely.
•
The garage door will move slowly the first
time it runs, until the Opener “learns” the
type of door.
•
Ensure the Magnetic Carriage Assembly is
engaged and is between the two Limit
Switches before operating the Opener.
