the door will stop when moving up or down.
NOTE: Door STOPS in the UP direction If anything
interferes with door travel. Door REVERSES in the
DOWN direction It anything interferes with the door
travel (including binding or unbalanced doors).

TRAVEL CYCLE. No limit adjustments are necessary when
the door opens and closes completely and doesn't reverse
unintentionally when fully closed.
The following chart outlines adjustment procedures. Run the opener through a
COMPLETE TRAVEL CYCLE AFTER EACH ADJUSTMENT.
NOTE: REPEATED OPERATION OF THE OPENER DURING ADJUSTMENT PROCEDURES MAY
CAUSE MOTOR TO OVERHEAT AND SHUT OFF. SIMPLY WAIT 15 MINUTES AND TRY AGAIN.
Read the chart carefully before proceeding to Step 2. Use a screwdriver to make limit adjustments.
LIMIT ADJUSTMENT CHART
IF DOOR DOES NOT OPEN COMPLETELY
BUT OPENS AT LEAST FIVE FEET IF OPENER REVERSES IN FULLY
CLOSED POSITION
Increase UP travel. Turn the UP LIMIT adjustment screw
clockwise. One turn equals 2" of travel.
If door does not open at least 5 feet: adjust UP
(OPEN) FORCE as explained in Step 2.
Decrease DOWN travel. Turn down limit adjustment
screw clockwise. One turn equals 2 inches of travel.
IF DOOR DOES NOT CLOSE COMPLETELY
Increase DOWN travel. Turn down limit adjustment
screw counterclockwise. One turn equals 2" of travel.
