CONNECTING GOOSENECK TO TRAILER (Continued).
It may be necessary to raise or lower the gooseneck tilt support arm (11)
with the gooseneck support lever (12) to assist in aligning the gooseneck
base to the trailer deck. It may also be necessary to back bump the
gooseneck slightly to engage the neck base slide bar (3). The bar is fully
engaged when the end of the bar resides in the bar recess hole.
Connect the air lines (9 and 10) between the trailer and the gooseneck.
