ADJUSTMENT STEP 3

Test the Safety Reversal System

TEST

With the door fully open, place a 1-1/2" (3.8 cm) 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 force the door arm beyond a straight up and down position. See the illustration on page 25.

Repeat the test.

When the door reverses on the 1-1/2" (3.8 cm) board, remove the obstruction and run the opener through 3 or 4 complete travel cycles to test adjustment.

If the unit continues to fail the Safety Reverse Test, call for a trained door systems technician.

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