Adjustments

3 - Test the Safety Reversal System

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.
• After ANY adjustments are made, the safety reversal system MUST be tested. Door
MUST reverse on contact with 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on the
floor.
1 With the door fully open, place a 1-1/2 inch (3.8 cm) board (or a 2x4 laid flat) on the floor,
centered under the garage door.
2 Press the remote control push button to close the door. The door MUST reverse when it makes
contact with the board.
If the door stops but does not reverse:
1. Repeat Program the Travel (see Adjustment Step 1);
2. Repeat the Safety Reversal test.
If the test continues to fail, call a trained door systems technician.

4 - Test the Protector System

Without a properly installed safety reversing sensor, persons (particularly small children)
could be SERIOUSLY INJURED or KILLED by a closing garage door.
1 Open the door. Place an obstruction in the path of the door.
2 Press the remote control push button to close the door. The door will not move more than an
inch (2.5 cm).
The garage door opener will not close from a remote control if the LED in either safety reversing
sensor is off (alerting you to the fact that the sensor is misaligned or obstructed).
If the garage door opener closes the door when the safety reversing sensor is obstructed (and the
sensors are no more than 6 inches [15 cm] above the floor), call for a trained door systems
technician.
