What? How?
Increased play in the milling head spindle can be reduced by
adjusting the spindle nut. The spindle nuts are readjusted by
reducing the thread flanks of the spindle nut with two take-up
screws. Due to the readjustment, it is necessary to check if
smooth movement over the entire way is still provided, other-
wise 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-
way.

Check the settings. The corresponding guideway must be
more easily moveable but ensure a stable guiding.
