Increased play in the milling head spindle can be reduced by
adjusting the spindle nut. The spindle nuts are reset by reduc-
ing the thread flanks of the spindle nut with two take-up
screws. After the reset, it is necessary to check if there is still
smooth movement over the entire path, otherwise wear is con-
siderably 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.
