Assemble the Door Arm:
• Fasten the straight and curved door arm sections
Door Arm to Trolley p27
together to the longest possible length (with a 2 or
Canadian 3/29/93
3 hole overlap).
• With the door closed, connect the straight door
arm section to the door bracket with a clevis pin.
• Secure with a ring fastener.
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 limit
• Turn the UP limit adjustment screw counter-
clockwise 5-1/2 turns.
• Press the Door Control push bar. 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.
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.
