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
bing opened or closed from the fully open position.
B. SECTIONAL DOOR INSTALLATION:
Connect according to Figure B, then proceed to Step 21.
