Vertical Adjustment
- Move panel to full open position. Insert adjustment tool (J-28652) under guide rail 3" behind front screws. Loosen screws and raise or lower guide rail. Adjust both sides as necessary.
- Using the same procedure but with adjustment tool 3" in front of screws, adjust guide rail at rear corners. If height adjustment is not enough, shim washers may be added between the panel and the cable support. See Figure and Figure .
