How?
An larger amount of backlash in the milling head spindle can
be reduced by adjusting the spindle nut. The spindle nut is
reset by reducing the thread flanks of the spindle nut with take-
up screws. After the reset, it is necessary to check if there is
still smooth movement over the entire path, otherwise wear is
considerably increased due to friction between the spindle nut
and the spindle.

Turn the take-up screws of the gib clockwise. The gib is
pushed further inward thus reducing the play in the guide
rail.
Check the settings. The corresponding guide rail must be
more easily movable but ensure stable guidance.
