runway, as it will need to be flipped over. Note: Using some type of hoist is recommended to

previously chosen corner for the Power Unit.
7. Unbolt all four Columns from the shipping brackets and place the Power Unit Column (#1) with
mount bracket in the above chosen corner. Arrange the other three Sub Columns (#2) in the
remaining corners.
8. Unpack the Crossbeams, Cover panels, Ramps, Drip Trays, Jack Tray, Lock Ladders and
Caster Kit from the lower Sub Runway (#2). Remove the linkage rod Cover Panels (#68, #69,
#70 & #71) (Fig. 3) if not already removed. They will be reinstalled later.
