Adjusting Spindle Speeds - Grizzly G0694 Owner's Manual

Adjusting Spindle
Speeds
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).
A = Low Range
100-1000 RPM
B = Mid Range
1000-2000 RPM
C = High Range
2000-3000 RPM
figure 21. speed ranges for each belt position.
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.
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.
