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 lim#
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.
iMPORTANT
SAFETY CHECK:
Test the Safety Reverse System 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 SERIOUSLYINJURED
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 1-1/2" high (3.8 cm) object (or 2x4 laid flat) on the
floor.

®
• 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 (2.5 cm),
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" (15 cm) above the floor), call for a
trained door systems technician.
Without a properly installed safety reversing sensor, persons
(particularly small children) could be SERIOUSLYINJURED
or KILLED by a closing garage door.
