ADJUSTMENT STEP 3
Test Safety Reverse System
THE SAFETY REVERSE SYSTEM TEST IS
IMPORTANT. GARAGE DOOR MUST RE-
VERSE ON CONTACT WITH A ONE-INCH
OBSTACLE PLACED ON THE FLOOR. FAILURE TO
PROPERLY ADJUST OPENER MAY RESULT IN
SERIOUS PERSONAL INJURY FROM A CLOSING
GARAGE DOOR. REPEAT TEST ONCE A MONTH AND
ADJUST AS NEEDED.
PROCEDURE: Place-a one-inch obstacle on the floor
under the garage door. Operate door in DOWN direction.
The door MUST reverse on the obstruction.
If the door STOPS on the obstruction, it is not traveling
far enough in the DOWN direction. Increase the DOWN
limit by turning DOWN limit adjustment screw
counterclockwise 1/4 turn. REPEAT TEST.
NOTE: Make sure limit adjustments do not force the
door arm beyond a straight up and down position.
See the illustration on Page 18/19.
When the door reverses on the one-inch obstacle,
remove the obstruction and run the opener through a
complete travel cycle.
Door MUST NOT reverse in closed position. Repeat
Adjustment Steps 1, 2 and 3 if necessary.
REPEAT ADJUSTMENT STEP 3 AFTER:
• EACH ADJUSTMENT OF DOOR ARM LENGTH, CLOSE
FORCE OR DOWN LIMIT.
• ANY REPAIR OR ADJUSTMENT OF GARAGE DOOR
(INCLUDING SPRINGS AND HARDWARE).
• ANY REPAIR OR BUCKLING OF THE GARAGE FLOOR R.
• ANY REPAIR OR ADJUSTMENT OF THE GARAGE DOOR
OPENER.
THE PROTECTOR SYSTEM
Installation of Optional Safety Feature
THE PROTECTOR SYSTEM PROVIDES AN ADDITIONAL
MEASURE OF SAFETY AGAINST A SMALL CHILD BEING
CAUGHT UNDER A GARAGE DOOR. It uses an invisible
beam which, when broken by an obstruction, causes a
closing door to open and prevents an open door from
closing. STRONGLY RECOMMENDED FOR HOMEOWNERS
WITH YOUNG CHILDREN.
After opener has been installed and adjusted, THE
PROTECTOR SYSTEM accessory can be installed.
Instructions are included with this optional
device.
