After operating the machine for a long period of time, clearances will drift on the turning and
milling/drilling spindles.
• Turning spindle: Adjustment is made by readjusting the round nut with locking slot on the end of
the spindle.
• Drilling/milling spindle: The big belt pulley and the spline sleeve assembly should be removed
first, then the round nut with locking slot on the top end of the spindle should be readjusted, then
the removed assemblies reinstalled.
