This is how to read the feed rate charts:
1. The box in the upper left-hand corner of each
chart tells whether that chart represents car-
riage feed movement for standard or metric
threads. These boxes are shaded in Figure
28.

The boxes in the top row of each chart
(excluding the box in the left-hand corner)
shows the thread pitches listed on that chart.
These boxes are shaded in Figure 29.

The boxes on the left-hand column (exclud-
ing the box in the upper left-hand corner)
represent the gear positions on each shaft.
These boxes are shaded in Figure 30 and
the shafts are called out with arrows.

4. Each shaft has room for two positions to
mount the gears—a forward position and
a rear position. Figure 31 separates these
positions into different shades for you to
understand better.
Figure 31. The shaded boxes show the thread
pitches listed on this chart.
Both forward and rear positions must be filled
on the shaft in order for the gears to work
properly. A good example of this is the blank
spot to the right of gear "F," as shown in the
chart in Figure 31. Although the chart shows
this as a blank spot, there should actually be
a spacer in this position on the machine. This
spacer is not listed on the chart, because the
chart only reflects ACTIVE gear positions.
