ALL ONE-PIECE DOORS
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).
• Make sure the garage door is fully 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.
• Pull the emergency release handle,
disconnecting the outer trolley from the inner
trolley by pulling straight down on the emergency
release handle and sliding the outer trolley back
toward the motor unit.
• Connect the curved door arm section to the
trolley using the 5/16"x1-1/4" clevis pin and ring
fastener.
NOTE: Adjusting the limits on the following page:
• The trolley will automatically connect. If not,
review the trolley lockout feature on page 33.
• 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.
