21 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 40 mm high object on the floor.
TEST
1. With the door fully open, place a 40 mm board 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.
ADJUST
If the door stops but does not reverse:
1. Review the installation instructions provided to ensure all steps were followed;
2. Repeat Program the Travel (see Adjustment Step 1 "Point 20");
3. Repeat the Safety Reversal test.
If the test continues to fail, call a trained door systems technician.
IMPORTANT SAFETY CHECK:
Test the Safety Reverse System after:
• Each adjustment of limits.
• Any repair to or adjustment of the door (including springs and hardware).
• Any repair to or buckling of the floor.
• Any repair to or adjustment of the garage door opener.
22 To Open the Door Manually
If possible, use emergency release handle to disengage door ONLY when garage door is CLOSED. Weak or broken springs
or unbalanced door could result in an open door falling rapidly and/or unexpectedly. NEVER use emergency release handle
unless garage doorway is clear of persons and obstructions.
Disengage any door locks before proceeding. The door should be fully closed if possible. Pull down on the emergency release handle until a click
noise is heard from the door opener and lift the door manually. To reconnect the door to the door opener, pull the emergency release handle straight
down a second time until a click noise is heard from the door opener. The door will reconnect on the next UP or DOWN operation.
TEST THE EMERGENCY RELEASE
1. Make sure the door is closed.
2. Pull the emergency release handle. The door should then be able to be opened manually.
3. Return the door to the closed position.
4. Pull the emergency handle a second time.
5. Reconnect the door to the door opener.
