necessary. After each adjustment, run the opener
through a compieto travel cvete.
If the door reverses during the down (close) cycle
and the opener lights aren't flashing
Increase DOWN (dose) force by turning the control
clockwise. Make 10 degree turn adjustments until the
door completes a dose cycle. After each adjustment,
run the opener through n cornptelo travel cyde. Do
