TABLE OF CONTENTS
Before you begin:
Disable locks (contact your door manufacturer for
information on disabling your door 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.
If your door binds, sticks, or is out of balance, call a
trained door systems technician.
If you have a one-piece door, the installation of your
garage door opener will be different. Follow the assembly
instructions included in this manual then proceed to the
Installation Instructions For One-Piece Doors included with
the garage door opener.
