ADJUSTMENT STEP 3

Test the Safety Reversal SystemGarage Door Installation

TEST

•With the door fully open, place a 38 mm obstacle 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 27.

•Repeat the test.

•When the door reverses on the 38 mm obstacle, 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.

Gate Installation

TEST

The opener must reverse if the gate comes in contact with an obstruction. A closing gate should reverse with little effort, and open completely. See Adjustment Step 2.

•Use 38 mm board laid flat against the wall or gate edge.

•SLIDING GATE DOOR, place a 38 mm board between the door and wall of a closing gate. Gate must reverse on the board and open completely. Repeat at opposite wall if two openers are installed.

•SWING OUT GATE, insert a 38 mm board between the closing gate sections. Gate sections must reverse and swing open completely.

ADJUST

•If the gate stops on the obstruction, it is not traveling far enough in the closing direction. Increase the DOWN limit adjustment screw counterclockwise 1/4 turn. Repeat test.

•When the gate reverses on a 38 mm board, remove the obstruction and run the opener through complete travel cycle to test adjustment.

If the gate will not reverse after repeated adjustment attempts, call for professional gate service.

WARNING

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

•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 38 mm obstacle on the floor. Gate MUST reverse on contact with 38 mm obstacle at the closing edge.
