Test the Safety Reversal System

TEST

•With the door fully open, place a one-inch board (or a 2x4 laid flat) on the floor, centered under the garage door.

•Operate the door in the down direction. The door must reverse on striking the obstruction.

ADJUST

•If the door stops on the obstruction, it is not traveling far enough in the down direction. Increase the DOWN limit by turning the DOWN limit adjustment screw counterclockwise 1/4 turn.

NOTE: On a sectional door, make sure limit adjustments do not cause the trolley to move within 2-1/2" of the trolley stop bolt. If necessary

lengthen straight door arm to maintain this minimum distance.

•Repeat the test.

•When the door reverses on the one-inch board, remove the obstruction and run the opener through 3 or 4 complete travel cycles to test adjustment.

IMPORTANT SAFETY CHECK:

Repeat Adjustment Steps 1, 2 and 3 after:

•Each adjustment of door arm length, limits, or force controls.

•Any repair to or adjustment of the garage door (including springs and hardware).

•Any repair to or buckling of the garage floor.

•Any repair to or adjustment of the opener.
