to select suitable gears to produce the threads required. (the change gears are standard acces-
sories). After the gears are changed, the gear box door must be closed. To engage the thread-
ing mode, the half-nut on the saddle must be engaged through the lever shown in the picture
below. (Fig. 5)When the half nut is engaged the longitudinal and cross feeds are inter-locked
and will only allow one option to operate. The direction of the threading, can be achieved by
switching the direction change shift on the feeding box. (Fig. 3)
