joint assembly with 1 x 2-1/2 in (63 mm) hardware. Note: Mounting position of azimuth
pivot jackscrew assembly is dependent upon azimuth range requirements and corre-
sponds with mounting position of 201488 outrigger plate or extension assembly.
Note: If optional motor drive system is included, install motors at this point. Refer to
installation instructions provided with motor kits.

bly; do not attach rope to small motor. Tie up loose conduit before lifting jack.
