Connect The Door Arm To The Trolley - Craftsman 139.18867 Owner's Manual

Assemble the Door Arm:

• With the door closed, connect the straight door arm
section to the door bracket with a clevis pin.

On one-piece doors, before connecting the door arm to the trolley the travel limits must be adjusted. Limit adjustment
screws are located on the right side panel as shown on page 28. Follow adjustment procedures below.
