ADJUSTMENT STEP 3

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 force the door arm beyond a straight up and down position. See the illustration on page 26.

•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.

WARNING

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

•Safety reversal system MUST be tested every month.

•If one control (force or travel limits) is adjusted, the other control may also need adjustment.

•After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with one-inch high object (or 2x4 laid flat) on the floor.

2x4 laid flat

ADJUSTMENT STEP 4

Test the Protector System®

•Press the remote control push button to open the door.

•Place the opener carton in the path of the door.

•Press the remote control push button to close the door. The door will not move more than an inch, and the opener lights will flash.

The garage door opener will not close from a remote if the indicator light in either sensor is off (alerting you to the fact that the sensor is misaligned or obstructed).

If the opener closes the door when the safety reversing sensor is obstructed (and the sensors are no more than 6" above the floor), call for a trained door systems technician.

WARNING

Without a properly installed safety reversing sensor, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.
