6.4.5 Adjusting the spindle nut on the cross slide
The cross spindle nut consists of two parts.

Slightly loosen both hexagon sockets in the centre of the cross slide.

Tighten the intermediary threaded pin, so the cross spindle nut is spread. This reduces the
play in the thread.

Tighten the hexagon sockets again and check the mobility of the spindle along the entire
length.
