SECTION 5: CONTROLS
Figure 7. Speed shifting levers.
Figure 8. Speed chart.
Never change speeds while spindle or motor
is in motion.
The speed of the spindle is controlled by the
positions of the speed control knobs.
See Figure
7. By positioning the knobs using the chart in
Figure 8 , you can achieve all of these speed
ranges: 70, 200, 220, 270, 360, 600, 800, 1000
and 1400 RPM.
The chart above shows the various combinations
of knob positions for achieving a desired speed.
Example:
To select a spindle speed of 600 RPM, move the
left-hand selector knob until the indicator arrow
on its hub is pointing to the “C”. Move the right-
hand selector knob until its indicator arrow is
pointed at the “3”.
