5. Turn the spindle ON, and slowly turn the
spindle speed dial to your calculated spindle
speed.
Figure 88. Quick change range lever.
If using the quick change gearbox, and it is
shifted into high, NEVER run the spindle at
speeds greater than 350 RPM as listed on
the label (Figure 88), or feed system damage
will occur. DO NOT shift any levers on the
headstock or quick change gearbox while the
spindle is turning, or damage will occur to the
gearing.
Make sure the variable speed dial is turned all
the way to the left (counterclockwise) before
turning the lathe ON, or the spindle may start
up at a dangerously high rate of speed.
4. Move the spindle range lever shown in
Figure 87 to the range that covers your
calculated spindle speed.
Note: To shift the spindle speed range lever, you
may need to rock the chuck by hand to get
the gears to align.

2. Use the chart in Figure 85 to determine the
available spindle speed range closest to your
calculated spindle speed.
