• Elevation Adjustment: If the elevation check did not
show any play between the column tube and the
support, go to the rotation adjustment. Otherwise,
raise and lower the arm with the elevating hand-
wheel. Tighten the black screws on the rightside of
the column support by 1/16th to 1/8th of a turn.
Tighten the two silver screws on the left side
slightly more. You will need two 1/2 in. wrenches or
sockets. Turn the elevating handwheel again. Ifthe
column tube binds, loosen the silver and 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.
