7.Remove fasteners (M8 x 16 socket head screws and M6 plain washers) that attach column spacers to machine bed and remove spacers/ outer columns from machine bed. Figure 13- 14A.

8.Remove fasteners (M8 x 20 socket head screws) that attach spacers to columns, move spacer down 100mm [4 inches] to lower set of mounting holes and re-attach spacers to columns. Figure 13-14B.

9.Reverse procedure to reassemble machine.

Note – When installing upper assembly

back into machine (removed in Step 3), slide upper assembly down into outer columns until lead screws contact plastic nuts and support upper assembly. Then, slowly turn height adjustment crank counterclockwise until two "clicks" are heard, one at each plastic nut. Now the upper assembly can be cranked down (turn height adjustment crank clockwise) for installation of special nut on bottom of each lead screw.
