Testthe SafetyReversal 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.
• Operatethe 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. Increasethe DOWNlimit by
turning the DOWNlimit 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.
• Repeatthe 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 ReverseTest, call for a
trained door systems technician.
IMPORTANTSAFETYCHECK:
Test the Safety ReverseSystem 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.
Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLYINJUREDor
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 1-1/2"
high (3.8 cm) object (or 2x4 laid flat) on the floor.
