TIGHTENING THE ARM AND COLUMN ADJUSTING THE COLUMN TUBE
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 it is unlocked, use the
following steps to tighten it.
• Using a phillips screwdriver, remove the rear cover
screws (2) and rear cover from the back of the arm.
This uncovers the bolts on the column.
• Tighten the top two bolts evenly until the arm is firm
and there is no vertical or horizontal movement.
• Also check the two bottom 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.

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 result in a
poor cut or difficulty in elevating the carriage. The
column tube is the upper portion of the column and
extends from the column support.
Note: It is critica/to 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 both the elevating action and
the rotating action. If a check does not show loose-
ness, do not perform the adju.stment.
• If the arm is not at 0" (straight forward), release the
arm lock knob, set the arm, and re-lock the arm
lock knob.
• Elevation check: To check the elevation movement,
place your hand under the front of the radial arm.
Press upward on the radial arm. There should be
no play between the column tube and the column
support. The whole assembly should move as one.
