figure 21. speed ranges for each belt position.
To change speed ranges:
1. disConneCt Lathe FroM poWer!
2. remove the threaded knob and open
the upper belt access panel, as shown in
figure 23.
the Model g0694 has three speed ranges for
maximum turning options. these ranges are
selected by changing belt positions on the motor
and spindle pulleys (
figure 21).
When turning a workpiece where a lot of mate-
rial must be removed and a rough finish does not
matter, low range, which has more torque, is best.
When turning a workpiece where a clean finish is
required, and only light cuts are made, high range
is best. Mid range is a compromise between
the two ranges. Use the speed dial to adjust the
spindle speed within each range.
refer to the chart in figure 22 help choosing the
correct spindle speed. note that both the diameter
of the workpiece and the type of cutting deter-
mines the spindle speed.

Always choose the correct spindle speed
for your operation. Using the wrong speed
may lead to the workpiece breaking loose
or being thrown from the lathe at a high rate
of speed, causing fatal or severe impact
injuries.
