TIGHTENING THE ARM AND COLUMN

See Figure 19.

There should be no play, vertical or horizontal, in the arm relative to the column. If you can move the arm up, down or sideways when )he arm lock is unlocked, use the followingsteps to tighten the arm.

Note: The arm should pivot only when the arm lock knob is unlocked and pulled forward to com- press the spring.

•Using a phillipsscrewdriver, remove the rear cover

screws (2) and rear cover from the back of the arm. This uncovers the belts on the column.

•Tighten the top two belts evenly until the arm is firm and there is no verticalor horizontal movement.

•Also check the two bettom hex nuts. It is not necessary to tighten them as tight as the upper bolts. However they should be tightened even and snug.

•Replace the rear cover and rear cover screws.

•Tighten screws securely.

ADJUSTING THE COLUMN TUBE

See Figures 20A - 20D.

The purpose of this procedure is to check whether the inner column tube is snug in the housing and to remove any looseness. Looseness could resultin a poor cut or difficultyin elevating the carriage. The column tube is the upper portion of the column and extends from the column support.

Note: It is criticalto remove all looseness with this procedure. If this procedure is not done cor- rectly,following adjustments will be wrong and could result in machine damage.

This procedure checks beth the elevating actionand the rotating action. If a check does not show loose- ness, do not perform the adjustment.

•If the arm is not at O"(straight forward), release the arm lock knob, set the arm, and re-lockthe arm lock knob.

•Elevation check:To check the elevation movement, place your hand under the frontof the radial arm. Press upward on the radial arm. There shouldbe minimal play between the column tube and the column support.The whole assembly shouldmove as one. See Figure 20A.
