3.Loosen keylocking bolts (See figure 7) and insert a 3/16- inch Hex-L wrench into the socket-head set-screw that

adjusts the column tube wedge key, as shown in figure 7. Rotate the set-screw slowly in (clockwise) until no side play can be felt in radial arm.

4.Check for binding by rotating the elevation crank. If the crank rotates with noitceable resistance, loosen the set-

screw by rotating the Hex-L wrench counterclockwise until rotation is normal. An effective method for finaliz-

ing the set-screw adjustment is to rotate the screw while the elevation crank is being rotated, checking for side play in radial arm as the adjustment progresses. The adjustment is correct when all side play of radial arm is eliminated and only very slight additional resistance can be felt when rotating the elevation crank.

5.If some radial arm side play can still be detected after performing the above adjustment, it will be necessary

to adjust the forward five screws through the right-, and left-hand column supports as follows:

a.While rotating the elevation crank, tighten the five column adjusting screws slightly at the forward edge of column supports. Each screw should be tightened only slightly, and each one the same amount, until a slight resistance can be felt when rotating the elevation crank, then each screw backed off just

enough to restore a normal feel to the elevation crank.

b.Recheck the adjustment of the column tube wedge key set-screw as outlined in preceding instructions.

6.After the above adjustments have been completed, re- check the radial arm for absence of side play.

7.When all side play has been eliminated, lock the column tube key in place by tightening keylocking bolts. (See figure 7.)

1.Place the large (front) table board upside-down on floor. Distinguish between the one through-bored (leveling screw) hole near the center of the board, and the seven counterbore holes. The counterbores are in the top sur- face of the board. Drive the T-nut into the through-hole.

(See figure 8 which shows the T-nut installed.)

2.With the front table board still in the upside-down posi- tion, locate the two pre-drilledscrew holes near each end of the table. Attach the two rear table support brackets to the table with two No. 10 x 5/8-inch screws in each bracket. (See figure 8.)

3.Place the 1/4-20 U-clip nut on the base cross member to receive the center front table attaching screw.

4.Place the large, front table board on the table supports. (See figure 9.)

5.Align the counterbore holes with matching holes in table supports.

6.Place a 17/64-inch plain washer and a 1/4-20 x 1-inch pan-head machine screw from loose parts pack in each of the six counterbore holes located above the table

supports. Use a 1/4-20 x 1-1/4-inch pan-head machine screw in counterbored hole at the center of the table board.
