TUBE
See fLgures 20A - 20D.
The purpose of this procedure
is to check whether
the
inner coJumn 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
coJumn tube is the upper portion of the column and
extends from the column support.
Note: It is
critical
to remove alJ looseness with this
procedure.
If this procedure is not done correctly,
folJowing 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 adjustment.
[]
if the arm is not at 0° (straight forward),
release the
arm lock knob, set the arm, and reqock the arm
lock knob.
