3. Pick up the rise and fall gear rack, identify the top and the
bottom, (the rack gearing is cut asymmetrically, with the gear
cut extending closer to the bottom), make sure you have the
rack the right way up, as it will allow you to drive the drill table
up and down over its full range, see fig 06.

4. Fit the rise and fall rack into the square recess in the
mounting bracket arm (2) casting, ensure that it is engaged
with the pinion, see fig 07. Lower the combined mechanism
over the column. Allow it to slide down the column until the
rise and fall rack is located in the cup chamfer in the top of
the mounting flange, see fig 08. Replace the cup chamfered
retaining collar over the column and slide it down onto the top
of the rack. Lock it in place with the grub screw, ensuring that
it has captured the upper end of the rack securely, but not too
tight that the rack cannot be swivelled around the pillar see
fig 09.

5. Locate and fit the crank handle (10) to the shaft, ensuring
that you tighten the grub screw onto the machined flat on the
shaft, this will keep the worm gear in position, see fig 10-11.
6. Check that the mounting bracket can be driven up and down
the column and can swivel around the pillar. Locate the lift and
shift clamping handle (8) and screw it into the threaded hole to
the rear of the mounting bracket arm and tighten, see fig 12.
Check it has 'pinched' up on the column and the bracket is
immobile; both in its up and down travel and swivel movement.
