1. Assemble the door arm:
• Fasten the straight and curved door arm sections
together to the longest possible length (with a 2
or 3 hole overlap).
• With the door closed, connect the straight door
arm section to the door bracket with the
5/16"x1-1/4" clevis pin.
• Secure with a ring fastener.
2. Adjustment procedures:
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 left side panel as shown on page 28. Follow
adjustment procedures below.
• Open door adjustment: decrease UP travel
limit
– Turn the UP limit adjustment screw
counter-clockwise 5-1/2 turns.
– Press the Door Control button. The trolley
will travel to the fully open position.
– Manually raise the door to the open
position (parallel to the floor), and lift the
door arm to the trolley. The arm should
touch the trolley just in back of the door
arm connector hole. Refer to the fully open
trolley/door arm positions in the illustration.
If the arm does not extend far enough,
adjust the limit further. One full turn equals
2" of trolley travel.
• Closed door adjustment: decrease DOWN
travel limit
– Turn the DOWN limit adjustment screw
clockwise 5 complete turns.

– Press the Door Control button. The trolley
will travel to the fully closed position.
– Manually close the door and lift the door
arm to the trolley. The arm should touch the
trolley just ahead of the door arm connector
hole. Refer to the fully closed trolley/door
arm positions in the illustration. If the arm is
behind the connector hole, adjust the limit
further. One full turn equals 2" of trolley
travel.
3. Connect the door arm to the trolley:
• Close the door and join the curved arm to the
connector hole in the trolley with the remaining
clevis pin. It may be necessary to lift the door
slightly to make the connection.
• Secure with a ring fastener.
• Run the opener through a complete travel cycle. If
the door has a slight "backward" slant in full open
position as shown in the illustration, decrease the
UP limit until the door is parallel to the floor.
NOTE: When setting the up limit on the following
page, the door should not have a "backward" slant
when fully open as illustrated below. A slight
backward slant will cause unnecessary bucking
and/or jerking operation as the door is being opened
or closed from the fully open position.
