Preparing your garage door WARNING Before you begin: • Disable locks. • Remove any ropes connected to garage door. • Complete the following test to make sure your garage door is balanced and is not sticking or binding: 1. Lift the door about halfway as shown. Release the door. If balanced, it should stay in place, supported entirely by its springs. 2. Raise and lower the door to see if there is any binding or sticking.
Planning Identify the type and height of your garage door. Survey your garage area to see if any of the conditions below apply to your installation. Additional materials may be required. You may find it helpful to refer back to this page and the accompanying illustrations as you proceed with the installation of your opener. SECTIONAL DOOR INSTALLATION FINISHED CEILING Support bracket & fastening hardware is required. See page 15.
