Elevation Adjustment: If the elevation check did not
show any play between the column tube and the
support, go to the rotationadjustment. Otherwise,
raise and lower the arm with the elevating hand-
wheel. Tighten the black screws on the right side of
the column supportby 1/16th to 1/8th of a turn.
Tighten the two silver screws on the left side
slightlymore. You will need two 1/2 in. wrenches or
sockets. Turn the elevating handwheel again. If the
column tube binds, loosen the silverand black
screws and turn the handwheel again. See Figure
20C.
• When the elevation is smooth, check for looseness
again by pressing upward on the front of the arm.
Repeat the previous step until elevation is smooth
with no play between the column tube and the
column support.
