NEVER shift the headstock feed direction lever on the headstock while the spindle is turning, or damage will occur to the headstock gearing.
If the threading or general carriage feed is required, the carriage lock (see Figure 91) must be disengaged. If the cross feed will be used for facing, the carriage lock should be engaged and the cross feed gib lock screw (see Figure 91) should be loose. If it is tight, loosen the cross feed gib lock using a 3mm hex wrench.
To engage the power feed:
1.Make sure the spindle is OFF and has come to a complete stop.
2.Shift the headstock feed direction lever to engage the leadscrew or feed rod. Sometimes you need to slightly rotate the handwheel of the component you are trying to engage, so that the gears can mesh.

3.Push down on the feed ON/OFF lever (see Figure 91) on the front of the apron to engage power feed for either the carriage or the cross slide.
4.Push the feed selection knob in to select carriage feed, or pull the feed selection knob out to select cross feed.
5.Adjust the feed clutch knob, shown in Figure 92, to set at which point the feed clutch will slip to avoid feed system overload.
—Tighten the feed clutch knob completely to seat the clutch. Next, count how many turns it takes to back it off completely.
Then tighten the knob 1⁄3 of the distance that was
and will not slip in the event of a feed system overload, resulting in feed system damage.
