STEP 2 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.
l Safety reversal system MUST be tested every month.
l After ANY adjustmentsare made, the safetyreversal 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 and does not reverse on the obstruction, increase the down travel (refer to Adjustment
Step 1). Repeat the test.When the door reversesupon contact with the 1-1/2 inch board, remove the
board and open/close the door 3 or 4 times to testthe adjustment. If the garage door opener continues
to fail the safetyreversal test, call a trained door systemstechnician.
