Wong,
Here's my best guess the half nuts may just slide out.
The 4 pins are for location, Proxxon went to a lot of trouble to locate it correctly. So caution is a wise option at the moment.
Test for the half nut engagement at the headstock, the middle (1/2 way between headstock and tailstock) and at the tailstock. See if you get the same amount of movement of the lead screw at each position.
