Assemble Door Arm
A. ONE-PIECE DOOR INSTALLATION:
Fasten the straight (1) and curved (2) door arm sections together to the longest possible length (with a 2 or 3 hole
overlap) using hardware (3,4 and 5). With the door closed connect the straight door arm section (1) to the door bracket
with clevis pin (6). Secure with ring fastener (7). Disconnect the inner and outer trolley. Slide the outer trolley back toward
the opener and join the curved arm (2) to the connector hole in the trolley (8) with clevis pin (6). It may be necessary to
lift the door slightly to make the connection. Secure with ring fastener (7).
NOTE: When setting the up limit, the door should not have a “backward” slant when fully open. A slight backward slant
(9) will cause unnecessary bucking and/or jerking operation as the door is being opened or closed from the fully open
position.
B. SECTIONAL DOOR INSTALLATION:
Connect according to Figure B, then proceed to Step 21.
