4. Looking down (toward the scalar plate)
on the linear section of the feed, locate
the alignment hole in the driven sprocket
of the linear section of the feed.
5. Make sure that the linear section of the
feed can rotate freely by turning it with
your hand.
NOTE: The CW & CCW alignment holes in the
collar under the driven sprocket are 180 degrees
apart and should be scribe marked on the body of
the OMT, above the driven sprocket.

(through the sprocket and the one in the
body underneath) are aligned and insert
your 2mm Allen wrench into the
alignment holes to prevent the feed from
rotating.
