Unattended Operation; Preparing Your Garage Door; Tools Needed - Craftsman CMXEOCG231 Owner's Manual

UNATTENDED OPERATION

Any device or feature that allows the door to close without being in the line of sight of the door is considered unattended close. Devices that allow unattended operation
are to be used ONLY with sectional doors.

PREPARING YOUR GARAGE DOOR

Before you begin:
1. Disable locks and remove any ropes connected to the garage door.
2. Lift the door halfway up. Release the door. If balanced, it should stay in
place, supported entirely by its springs.
3. Raise and lower the door to check for binding or sticking. If your door
binds, sticks, or is out of balance, call a trained door systems technician.
4. Check the seal on the bottom of the door. Any gap between the floor and
the bottom of the door must not exceed 1/4" (6 mm). Otherwise, the safety
reversal system may not work properly.
5. The opener should be installed above the center of the door. If there is a
torsion spring or center bearing plate in the way of the header bracket, it
may be installed within 4 feet (1.2 m) to the left or right of the door center.
