To tighten the fasteners properly:
CAUTION: Upright support fasteners must be properly aligned
and wrench-tightened in the order described below. If improperly
assembled, the upright supports can rub against the ramp. Before
you begin, verify that the base and lift covers are properly aligned
and that the gap between them is even. If not, move the upright
supports until the covers are properly aligned.
1. Fully tighten the two sets of fasteners on the back of the
center column support.
