Note
To minimize crank backlash, tighten table lock, rotate elevation worm shaft clockwise, then assemble
crank tight against table support and tighten set screw.
2. Feed the gear rack through the slot in the table support so that the teeth are facing out and the
longer smooth end faces up. The worm gear should engage the gear rack.
See Figure 7.
3. Using both hands, slide the entire assembly onto the column until the bottom of the gear rack is
positioned against the column.
4. Slide the column collar, bevel side down, over the column until the beveled side engages the
beveled end of the gear rack. Tighten the set screw in the collar using the 4 mm hex wrench. Do
not overtighten.
Note
Table should be able to move side to side. Do not overtighten set screw.
5. Slide the column collar over the column until the beveled side engages the beveled end of the gear
rack.
6. Check column collar for proper adjustment. Collar should not be angled on the column and it should
be positioned so rack will slide freely in collar when table is rotated 360° around column tube. If
readjusted, only tighten set screw enough to keep collar in place.
