How do I set the travel limits on my Linear garage door operator?

Travel limits are set on the LDO/LSO/LCO series operators by adjusting the limit adjusting screws accessed through the holes on the left hand side of the operator. These are marked "CLOSE LIMIT" and "OPEN LIMIT."

Turning the appropriate adjustment screw clockwise will cause the door to stop at a higher position. Turning the appropriate adjusting screw counterclockwise will cause the door to stop at a lower position. One complete turn of the screw will change the stopping point by about 2.5 inches.
